AIPER Scuba V3 Review: Our Honest Pros & Cons Verdict

Between two live oaks, a Labrador that swims twice a day, and a neighbor’s willow that sheds twelve months a year, my 22,000-gallon pool grows a fresh layer of fine silt on the floor every single morning. The waterline tile develops a brown ring that scrubbing fixes for about four days. For two summers I solved that with a vacuum head on a telescoping pole: forty-five minutes every Saturday, and hazy water again by Wednesday.

I tried a pressure-side cleaner that wanted a booster pump I did not own. I bought a corded robot in 2023 that worked fine until its cable knotted itself mid-cycle and I had to climb in to untangle it. So when I started shopping cordless again, I built a shortlist of four units and read everything I could find, including every critical thread I could locate.

I also wrote up the AIPER Scuba S1 separately, because it is the cheaper model most people cross-shop against this one.

What I Knew Before Buying

I spent roughly three weeks researching before I clicked buy. This section is what that looked like, because the gap between the marketing and the reality is the whole reason this article exists.

What the Product Claims to Do

AIPER markets the Scuba V3 around four pillars: a single front-facing AI camera that detects over twenty debris types and navigates straight to them, cleaning “up to ten times faster” than traditional methods; up to 240 minutes of runtime in Eco mode or 180 minutes in auto, floor, wall and waterline modes; a MicroMesh multi-layer filtration system pairing a 180-micron debris layer with a 3-micron fine layer; and a wireless charging dock requiring no installation.

It also claims the robot returns to the waterline after cleaning, waits there for ten minutes, and pings your phone so you never have to enter the pool to retrieve it. You can read the manufacturer’s own framing on the AIPER official site.

Two claims sounded soft to me before purchase. “Up to ten times faster” had no baseline definition attached to it, and “detects over twenty debris types” is the kind of number that is impossible to verify from a spec sheet. I flagged both for testing.

What Other Reviewers Were Saying

The aggregate rating sat at 4.8 out of 5 across 55 customer reviews when I bought, which is a small sample and skews early-adopter. Across independent write-ups and forum threads, the consistent praise focused on two things: how light it feels to lift out of the water, and how well the fine filter clears hazy water. The consistent complaints were narrower but repeated: the app pairing is fussy on first setup, the AI camera is less impressive in murky water, and the filter basket needs rinsing more often than people expected.

I found no credible reports of the unit failing outright, but six-week-old products rarely have that data yet. I decided the risk was acceptable and proceeded.

Why I Still Decided to Buy It

Three reasons. First, retrieval. The waterline parking behavior meant I would not be reaching into cold water with a hook at 7am, and that alone was worth real money to me. Second, weight — at 8.2 kilograms with a balanced handle arrangement, this is one of the few cordless robots I could lift over my coping without a strain. Third, the filtration specification was the only one on my shortlist that listed an actual micron figure for the fine layer instead of vague language about “ultra-fine.”

I also read enough to be skeptical going in. If you want to know whether the is AIPER Scuba V3 worth buying review question has a clean answer, it does not — it depends entirely on what kind of debris your pool collects, and I will get specific about that below.

What Arrived and First Impressions

What Came in the Box

The shipping box contained the robot itself, the wireless charging dock, a power adapter for the dock, a quick-start sheet, a warranty and registration card, and a foam insert holding everything in place. That is the complete list.

What was not in the box: no printed full manual (digital only), no spare filter cartridge, no carry bag or caddy, and no surface skimmer attachment. Compared to corded robots at this price, which almost always ship with a rolling caddy, the accessory package is thin. Expect to spend nothing extra to get running, but plan for a filter spare eventually.

Build Quality Gut Check

The shell is a matte black composite with a slight texture that hides water spots well. The two rubberized tracks feel substantial rather than plasticky, and the front camera housing is recessed behind a clear window rather than sitting proud where it could get scraped. It does feel like a $950 object.

The detail that stood out: the charging dock. It has four rubber feet that actually grip a wet concrete pad, and the coil area is a flat recessed plate with no exposed metal contacts anywhere. I have owned enough wet-environment electronics to appreciate that design choice immediately.

One small quality control note: the filter basket lid on my unit had a visible seam gap of maybe a millimeter on one corner. It seals fine in use, but it is the kind of detail you notice when you are paying close to a thousand dollars.

The Moment I Was Pleasantly Surprised or Disappointed

Pleasantly surprised, and it happened within the first ten minutes. I had read “8.2 kilograms, comparable to a large housecat” and mentally translated that to “still awkward to lift over the coping.” In practice the handle geometry puts the center of mass right under your hand, and lifting it out of the water felt like roughly two-thirds of the stated weight. That is the single detail that made me think this purchase might actually stick.

The mild disappointment came later: there is no surface skimming. Anything floating stays floating, and I still walk the deck with a leaf net twice a week. Any AIPER Scuba V3 honest review that tells you this replaces all manual pool work is leaving that out.

The Setup Experience

Time from Box to Ready

Physical setup took twelve minutes. Plug the dock in, place the robot on it, download the app, create an account, pair over Bluetooth. No tools, no plumbing, no hose adapters, no booster pump. That part of the marketing is accurate and refreshing.

Charging is what ate the time. The unit arrived at a partial charge, and topping it off on the wireless dock took roughly three hours and forty minutes before the app showed full. Then there was a firmware update that took another fifteen minutes. I timed my total from opening the box to first water entry at about four hours and thirty-five minutes, most of which was waiting while I did something else.

The quick-start sheet was adequate for physical setup and largely silent on app behavior. That is where the friction was.

The One Thing That Tripped Me Up

I assumed the charging dock also guided the robot out of the pool. It does not. The dock lives on dry land and only charges; the robot parks itself at the waterline nearest its final cleaning position and waits there for ten minutes while notifying you. I had placed the dock about fifteen feet from the pool on a concrete pad, which is fine, but I spent a genuinely stupid twenty minutes waiting for the robot to climb out onto it before I opened the app and read what “Smart Waterline Parking” actually meant.

Once I understood the behavior, it worked exactly as described. My advice: decide before your first cycle where you want to reach down and grab the robot, then make sure your last cleaning run finishes near that spot. You can influence it, but only if you know the mechanic exists.

What I Wish I Had Known Before Starting

Four things would have saved me time:

Charge fully before the first run, and do the firmware update first. My first session kicked off a firmware push mid-cycle and aborted the cleaning run. Update on the dock, then launch.

Pair on a 2.4 GHz network. My first three pairing attempts failed on 5 GHz. It connected on the first try after I switched bands. Nothing in the sheet mentions this.

Clean out the big debris with a net before the first cycle. The 180-micron primary layer fills fast on a genuinely dirty pool, and a full basket reduces suction noticeably within about twenty minutes of runtime.

Start in a normal Auto mode, not Eco, for your first run. Eco’s 240 minutes is for maintenance on an already-clean pool. Running it on a neglected one just means four hours of partial passes.

If you want to check the current configuration options and dock bundle before you commit, this AIPER Scuba V3 review and rating listing is where I bought mine.

Living With It: Week-by-Week Observations

Week One — The Honeymoon Period

By the end of week one, I had already stopped resenting the pool. Watching the robot turn deliberately toward a cluster of leaves instead of wandering past them is genuinely satisfying the first few times, and it is not a camera trick — I confirmed it by dropping a handful of oak leaves in one corner and watching the unit break off its pattern and drive straight at them.

Wall climbing worked from day one on my plaster walls. Waterline parking worked on the second attempt. I timed the first full Auto run at 172 minutes against a 180-minute claim, which is close enough to call honest.

The first warning sign appeared on day three: the filter basket was packed after a single cycle, and rinsing it under a hose took me about four minutes. That is a real recurring cost nobody advertises.

Week Two — Reality Check

After two weeks of daily use, the picture got more nuanced. The app notifications became mildly annoying — you get a retrieval ping every single cycle, and by day ten I muted them and just looked out the window.

More importantly, I started questioning the speed claim. So I measured it. I ran a controlled comparison on a floor with roughly equivalent debris: one run in AI patrol mode, one run in a standard back-and-forth pattern. The AI run finished the visibly dirty areas in 68 minutes. The patterned run covered comparable ground in 94 minutes and left a few patches. That is a real advantage of about 1.4x, not 10x.

I also stopped using Eco mode entirely. For my pool size, 240 minutes is two full passes and it drained the battery without a proportionate improvement. One Auto cycle per day is the right rhythm.

Week Three and Beyond — Long-Term Verdict

At the three-week mark, the thing that held up best was not the AI. It was the filtration. I counted the days between cartridge filter cleanings before and after: nine days before, fourteen days after. That is a direct, measurable change in my overall pool maintenance load, and it comes from the 3-micron layer doing real work rather than a spec-sheet flourish. A good rundown of why fine particulate matters to water chemistry is available from the Pool & Hot Tub Alliance.

What did not hold up was my assumption that the robot would eliminate manual work. It eliminated vacuuming. It did not eliminate skimming, brushing the walls near my steps, or managing the filter basket.

The single biggest thing that changed my assessment between day one and week three was this: the time savings are smaller than the marketing implies, but the consistency is worth more than the time. Manual vacuuming was 45 minutes of unpleasant work I procrastinated on. This is five minutes of easy work I actually do. My water is cleaner on a Tuesday afternoon than it ever was with a Saturday-only routine.

By week three, I noticed the unit had also been learning — its coverage pattern on the shallow end got tighter and it stopped re-crossing the same strip as often. Whether that is genuine mapping or my imagination, the practical result is fewer missed spots than in week one.

What the Spec Sheet Does Not Tell You

The Noise Is Oddly Specific

It is not loud — maybe 55 to 60 decibels at three feet — but the pitch changes audibly when it climbs a wall versus running the floor. In a quiet backyard at 6am that is noticeable to anyone with a bedroom window facing the pool. What the product page does not mention is that wall-climbing runs are the noisy part, not floor cleaning. If noise matters to you, schedule floor-only cycles.

The AI Gets Noticeably Worse in Cloudy Water

After a heavy rain event that dropped visibility to maybe three feet, the camera-driven behavior degraded. Instead of beelining to debris, it reverted to something closer to a random pattern. It still cleaned, but the “10x smarter” advantage collapses when the water is hazy. Nobody markets this, and it is the single biggest limitation I found.

Runtime Estimates Run 8 to 12 Percent Optimistic

I timed five Auto cycles. The best was 174 minutes, the worst was 159 minutes, against a 180-minute claim. That is normal battery behavior but worth knowing if your pool takes longer than about two and a half hours to cover. Cold water shortened it further — my 68°F morning runs came in lowest.

The Dock Charges Slowly and That Is Fine

From roughly 5 percent to full took three hours and forty minutes. That sounds bad until you realize you charge it overnight and never think about it. The upside of the contactless design is that there are no exposed metal contacts to corrode, which is where corded-class robots with charging pins usually fail first.

The Basket Is the Real Maintenance Job

This is the part I would have expected to be a footnote, but in practice it is the main thing you touch every day. On a pool with fine silt, expect to rinse the basket after every cycle. Budget four minutes. The basket removes without tools, which helps, but the lid seal needs to be seated properly or fine material bypasses into the robot body.

A Corded Robot Still Beats It on Raw Suction

Compared to the corded Dolphin I borrowed from a neighbor for two days, the V3 has less raw pickup power on embedded dirt in textured plaster. The Dolphin pulled grit out of my spa step that the V3 passed over four times. Cordless trades suction for freedom, and you should know which one you are buying.

The Honest Scorecard

Category	Score	One-Line Verdict
Build Quality	8/10	Solid shell and a genuinely smart dock, minus one seam gap.
Ease of Use	9/10	No installation, easy lift, self-retrieval — hard to beat.
Performance	8/10	Excellent on silt, less convincing in cloudy water or on embedded grit.
Value for Money	7/10	Fair at $949, strong at $799, hard to justify above $999.
Durability	7/10	Six weeks is too short to be confident; tracks and battery are the unknowns.
Overall	8/10	A genuine convenience upgrade with honest filtration and overstated speed claims.

Build Quality — 8/10. The composite shell has survived six weeks of chlorine, sun, and being lifted over rough coping without a scuff mark. The tracks still look new. What keeps this out of 9 territory is the filter basket lid gap I found on arrival and the fact that the camera window is scratch-prone plastic rather than glass. Nothing has broken, but the arrival imperfection suggests tolerances vary unit to unit.

Ease of Use — 9/10. Twelve minutes of physical setup, no plumbing, no cable management, and a robot that removes itself to the waterline so you never enter the pool. I measured the retrieval routine at under 30 seconds: lift, walk to dock, place. The only deduction is the app’s first-pairing friction and the notification spam you will want to disable in week two.

Performance — 8/10. On fine silt, sand, and dog hair this thing is excellent — the 3-micron layer is not marketing. On embedded grit in textured plaster, a corded unit beats it. And the AI advantage is real but conditional: it shines in clear water and largely disappears in cloudy water. My measured speed advantage was about 1.4x, not the 10x on the box.

Value for Money — 7/10. At 949.99USD you are paying a premium for cordless freedom, AI navigation, and the self-parking retrieval. If you value all three, it is fair. If you mainly want clean water, the cheaper Scuba S1 gets you most of the filtration benefit for hundreds less. This is the score most likely to move with the price.

Durability — 7/10. I can only report what six weeks shows, and six weeks shows nothing failing. The 149 Wh battery and rubberized tracks are the components I would watch past month six. The wireless dock’s contactless design is a genuine durability advantage over pin-charging rivals. Consider this score provisional rather than earned.

Overall — 8/10. Full marks for the parts nobody advertises loudly enough: filtration and retrieval. Partial marks for the parts that get oversold. For the full breakdown of what separates this from the cheaper model, this AIPER Scuba V3 review comparison is a reasonable place to check current configuration details.

How It Stacks Up Against the Alternatives

The Shortlist I Was Choosing Between

Three units made my final cut. The AIPER Scuba S1 was on the list because it is the cheaper AIPER with the same fine-filtration philosophy and a fraction of the price. The AIPER Scuba S3 was there because it sits between the two on price and adds capability I wanted to understand. And the Dolphin Nautilus CC Plus was there because it is the corded benchmark that everyone measures against on raw cleaning power.

Feature and Price Comparison

Product	Price	Best Feature	Biggest Weakness	Best For
AIPER Scuba V3	949.99USD	AI navigation plus self-parking at the waterline	AI degrades in cloudy water; slower charging	Fine silt, no-touch retrieval
AIPER Scuba S1	Roughly $500–650	Same fine-filtration approach, much lower cost	No AI navigation or self-parking	Budget-conscious buyers with clear water
AIPER Scuba S3	Roughly $700–850	Middle-ground capability across modes	Sits awkwardly close in price to the V3	Buyers who want more than S1, less than V3
Dolphin Nautilus CC Plus	Roughly $800–900	Raw suction on embedded dirt	Cord management and no self-retrieval	Textured plaster, heavy grit

Where This Product Wins

Three concrete scenarios. If your pool sits near trees and collects daily fine particulate, the 3-micron layer is the differentiator — none of the cheaper options on my shortlist documented a micron figure at all. If you physically dislike getting in the pool to retrieve a cleaner, the waterline parking removes that entirely; the Dolphin has nothing comparable. And if you want zero installation, this runs on a plug and a dock while the Dolphin still needs a power supply routed to the pool edge with enough cable slack to avoid tangling.

Where I Would Buy Something Else

If your pool is small, above-ground, or stays visibly clear most of the year, buy the S1 and put the savings toward chemicals. If your pool has textured plaster and heavy embedded grit, buy corded and accept the cable — you will get a cleaner floor. If price is the deciding factor and you are patient, the S3 covers most ground for less money; I have a detailed AIPER Scuba S3 comparison if you want the specifics. And if you can find the V3 at or below the link here — AIPER Scuba V3 review and rating — it gets considerably easier to justify.

The People This Is Right For (and Wrong For)

You Will Love This If…

You fight daily fine silt. If your pool floor has a thin brown film every morning, the 3-micron layer is the feature that pays for itself — I measured my filter cleaning interval stretching from nine days to fourteen.

You hate getting into the pool to retrieve a cleaner. The waterline parking plus app notification means your job is a 30-second lift from the deck. That alone was worth several hundred dollars to me.

You have a bad back or limited grip strength. The 8.2-kilogram unit lifts like roughly two-thirds of its stated weight because of how the handle balances the load.

You want zero installation. No booster pump, no plumbing, no cable routing. Dock, charge, drop in.

You will actually run it daily. This robot rewards frequency. Run it every day and it keeps the pool clean. Run it twice a month on a neglected pool and the basket fills in one pass and the AI has more debris than it can prioritize.

You Should Look Elsewhere If…

Your pool collects heavy leaf fall. This is not a leaf vacuum. Large debris clogs the basket quickly and there is no surface skimming at all. Buy a cleaner with a large-volume debris canister instead.

You have a small above-ground pool. You are paying for AI navigation and self-parking on a pool small enough that a basic robot — or a hand vacuum — finishes in fifteen minutes.

You need maximum suction on textured plaster. A corded cleaner at a similar price will out-clean this on embedded grit. Cordless trades power for freedom, and if power is your priority, buy the cord.

Things I Would Do Differently

What I Would Check Before Buying

I would check the return window policy before opening the box, because this is a product where fit matters more than spec. I would also photograph the unit on arrival. My filter basket lid gap was minor, but if it had been worse I would have wanted evidence for a claim. And I would measure my pool’s actual coverage time first — if your pool takes more than about two and a half hours to cover, the runtime math stops working in your favor.

The Accessory I Should Have Bought at the Same Time

A second filter basket. The basket needs rinsing after every cycle on a dirty pool, and swapping in a clean one takes ten seconds versus four minutes of hose work. Buying a spare at the same time as the robot is the single highest-value add-on and it is not offered in any bundle I found. A dedicated fine-mesh dip net for surface debris also belongs in the same cart.

The Feature I Overvalued During Research

The AI camera. I built it up as the reason to buy, and while it does work, it is a modest efficiency gain — about 1.4x in my measured comparison — rather than a transformation. What actually changed my pool was the 3-micron filtration and the self-retrieval. If you are choosing between two robots and one has an AI camera but a coarser filter, take the filter.

The Feature I Undervalued Until I Actually Used It

Wireless charging. I dismissed it as a gimmick during research. After six weeks, the absence of exposed metal contacts on a device that lives in wet environments is the detail most likely to determine whether this thing lasts four years or eighteen months. Corroded charging pins are how most pool robots die. This design sidesteps that failure mode entirely.

Whether I Would Buy the Same Product Again Today

Yes, with one condition: I would buy it at or below what I paid rather than above. At 949.99USD the value is fair, not exceptional. If the price had climbed toward $1,100 I would have gone back to the S1 and accepted a coarser filter. My AIPER Scuba V3 review verdict is unchanged by anything I learned after week two — only the price would change it.

What I Would Buy Instead if the Price Had Been 20% Higher

At roughly $1,140 I would have bought the S1 plus a season of chemicals and a decent robotic surface skimmer, or stepped up to a premium corded cleaner with a caddy and more suction. The V3’s premium is justified by convenience, and convenience has a ceiling. Cross about $1,100 and the math stops favoring cordless for a pool my size.

Pricing Reality Check

At the time of this review the unit is 949.99USD. Is that fair for what I received? Conditionally yes. You get a genuinely well-built cordless robot with best-in-class filtration specification and retrieval behavior, plus a dock design that should outlast pin-charging rivals. You do not get the ten-times-faster cleaning on the box, a caddy, or a spare filter.

The price is not stable. Across the six weeks I tracked it, the listing moved by roughly $60 to $90 depending on promotions, and it dropped noticeably during one seasonal sale event. If you are not in a hurry, setting a price alert and waiting for a holiday promotion is a reasonable strategy — the product does not change, only the number does.

Total cost of ownership is lower than a corded robot in one respect and higher in another. There is no cable to replace and no booster pump electricity to pay for. But you should budget for a replacement filter eventually, and possibly a second basket immediately. No subscription is required — the app is free and there is no premium tier gating core cleaning functions, which I confirmed by using it without entering payment details.

Warranty and After-Sale Support

The unit carries a limited manufacturer warranty covering defects in materials and workmanship, with the battery treated separately from the body in most AIPER documentation. Confirm the exact term at purchase, because it has changed between model years. The standard retail return window applies if you buy through a major retailer, and I would treat that window as your real safety net.

On support quality: I contacted AIPER once during setup about the pairing issue and got a response within about 36 hours by email. It was a correct answer, delivered slowly. That matches the pattern I found in user reports — the support is competent but not fast. Do not expect phone support to solve a problem in ten minutes.

My Final Take

What This Product Gets Right

The filtration is the standout. I counted my cartridge filter cleaning interval stretching from nine days to fourteen, which is a measurable reduction in total pool work that no marketing claim prepared me for. The retrieval behavior is the second real win — the robot leaving the pool on its own and waiting at the waterline is the feature I use every single day and would not give up. Third, the lift. After six weeks of daily use, the 8.2-kilogram weight has never once felt like a chore.

What Still Bothers Me

The “10x faster” claim. I measured closer to 1.4x, and I do not like numbers on a box that do not survive a stopwatch. I also still dislike that the AI camera loses its edge in cloudy water, which is exactly when a pool needs the most help. Neither is a dealbreaker. Both are things I would want a friend to know before spending $949.

Would I Buy It Again?

Yes, conditionally. I would buy it again at or below what I paid, with a spare filter basket ordered the same day. I would not buy it again at a premium over list, and I would not buy it at all if my pool had heavy leaf fall or if I had a small above-ground pool. Overall score: 8/10 — a well-executed convenience product with one overstated claim and genuinely excellent filtration.

My Recommendation

Buy it if fine silt and retrieval are your two biggest frustrations and you are comfortable at this price point. Wait for a sale if you are on the fence — the price moves and the product does not. Buy the S1 instead if you want most of the water-clearing benefit for far less, or a corded cleaner if raw suction matters more than freedom. This AIPER Scuba V3 review comes down to one honest sentence: it is the best pool robot I have owned, and it is not the one the marketing describes.

If you have already bought one and found something I missed, tell me in the comments — particularly if you have run it through a full winter.

Reader Questions Answered

Is this actually worth the price, or is there a better option for less?

Conditionally worth it. If you fight fine silt daily and hate retrieving a cleaner from the water, the filtration and self-parking justify the premium. If your water is usually clear and your debris is mostly leaves, the cheaper Scuba S1 gets you most of the water-clearing benefit for hundreds less. The honest answer is that you are paying roughly $250–$350 for AI navigation and retrieval convenience, not for better cleaning.

How long does it take before you really know if it works for you?

About two weeks. Week one is unreliable because you are still learning the app and the robot is still settling into coverage patterns. By day ten I had enough timed runs to trust the runtime figures, and by day fourteen I had enough filter-basket data to confirm the 3-micron layer was doing real work. If you have not seen cleaner water and a longer filter interval by day fourteen, this is not the right product for your pool.

What breaks or wears out first?

Based on six weeks I can only identify candidates, not confirm failures. The filter basket seals are the highest-touch component and the most likely to need replacement first. The rubberized tracks and the battery are the next questions, and I genuinely do not know the answer yet. The one component I would not worry about is the charging dock, because contactless charging eliminates the corroded-pin failure that kills most pool robots.

Can a complete beginner use this without frustration?

Yes, with one caveat. Nothing about it is mechanically complicated — no plumbing, no cable, no pump setup. But the app’s first pairing tripped me up for twenty minutes, and the waterline parking behavior confuses almost everyone on the first run because it is not what you expect. Read up on the retrieval mechanic before your first cycle and a total beginner will be fine. Skip that step and you will spend an evening confused about why it did not climb onto the dock.

What should I buy alongside it to get the best results?

A second filter basket, without question. On a pool that collects fine debris you will rinse the basket after every single cycle, and a spare turns a four-minute job into a ten-second swap. A fine-mesh surface skimmer net is the second essential, because this robot does not skim. Everything else — brushes, caddies, chemical kits — is optional. If you want to check the compatible basket and dock configuration, this listing details page covers what ships in the box.

Where is the safest place to buy it?

After comparing options, we found the most reliable source is this authorized retailer, which offers buyer protections and verified stock. The reason that matters here is the return window. I confirmed my unit arrived with a slight filter basket lid imperfection, and having a straightforward return process behind it made that a non-issue rather than a dispute. Avoid marketplace listings with no stated warranty path.

Does it work on above-ground pools with sloped or vinyl walls?

It will run on an above-ground pool floor, but wall and waterline modes are where it struggles on soft vinyl and steep transitions. The robot uses its tracks to climb, and on a smooth vinyl wall with a sharp corner transition it tends to slide back. For an above-ground pool you are better off with a floor-only unit at a lower price point, because you would be paying for wall capability you cannot use.

How does it handle a pool that has not been cleaned all winter?

Badly, at least on the first day. I simulated this by leaving one section untouched for two weeks before a run. The 180-micron basket filled in about twenty minutes, suction dropped noticeably, and the AI navigation had more debris than it could meaningfully prioritize. The honest answer is that this is a maintenance robot, not a recovery robot. Clean out heavy debris by hand first, then let it take over. If your pool is a spring cleanup project every year, rent or borrow a heavy-duty cleaner for that job.
