AquaSense 2 Ultra
4 independent reviewsRead the findings →Beatbot's big camera-guided pool robot, which goes back for leaves it missed. It's an excellent underwater cleaner for awkward pools. It's very heavy to lift out, though, and its surface skimming is hit and miss.

Feedback
What reviewers found
We use four home tests from three publications: PCWorld in 2025, a PCWorld retest in an above-ground pool in 2026, Digital Trends and The Gadgeteer. All four found it an excellent underwater cleaner, and in both PCWorld tests the camera found nine of ten leaves added after a run. All four also flag the weight. Skimming is where they part: both PCWorld tests found it pushed floating leaves away, while The Gadgeteer and Digital Trends were happy with it.

Floor, wall and waterline
Mixed resultsUnderwater it excels: Digital Trends saw floor and walls cleaned, and the PCWorld retest saw years-old grime lines lifted. Skimming splits reviewers, as PCWorld and the PCWorld retest found its bow wave pushes floating leaves away, while The Gadgeteer and Digital Trends were happy with it.
Debris
Reviewers rate it highlySunken debris is its strength. Its camera found nine of ten leaves added after a run in both PCWorld and the PCWorld retest, Digital Trends saw poured-in sand picked up, and The Gadgeteer filled the basket after garden work. The PCWorld retest says pollen can slip through the standard filter.
Coverage and navigation
Reviewers rate it highlyDigital Trends found it mapped accurately, cleaned most of the stairs and didn't catch on wall jets. The PCWorld retest watched it work round a hanging ladder without sticking, and The Gadgeteer found it didn't miss areas.
Battery and charging
Reviewers rate it highlyPCWorld got about 6 hours in the water, Digital Trends usually managed two custom floor cleans per charge, and The Gadgeteer liked the charging dock that keeps it ready. No reviewer found run time a problem.
Filter and retrieval
Mixed resultsIt parks at the edge and drains, which Digital Trends and The Gadgeteer found makes it easier to lift out. But it's heavy: PCWorld found it near 20kg straight out of the water, and Digital Trends suggests smaller or older owners pick a lighter robot.
Pool types it suits
Reviewers rate it highlyIt worked well in every pool tested: an in-ground pool with steps and wall jets for Digital Trends, an above-ground pool with a hanging ladder for the PCWorld retest, and a kidney-shaped pool for The Gadgeteer.
Reliability and support
Not enough evidenceOnly Digital Trends commented, finding no loose parts or wear after a few weeks. None of the reviews we use ran it long-term or judged Beatbot's support.
Value
Mixed resultsThe Gadgeteer thinks the time it saves justifies the price if you can afford it. Digital Trends calls it overkill for most pools, noting rivals such as the Aiper Scuba X1 Pro Max offer similar features for less.
Verdicts come from independent, hands-on, finished reviews. An area needs at least two of them before we say more than “Not enough evidence”. We don't score robots ourselves. How this works
Superb underwater, with a second look
PCWorld had its pool free of debris after three hours, then scattered ten more leaves, and the camera found all but one. The PCWorld retest got the same nine out of ten, with no visible dirt left after 85 minutes, and it lifted most of the grime lines that had built up over years. Digital Trends found it mapped accurately and cleaned floor, walls and most of the stairs, while The Gadgeteer filled its basket after a garden clean-up. If sunken leaves are your problem, this is where it shines.
Skimming depends on who you ask
Both PCWorld tests saw the robot's bow wave push floating leaves aside. PCWorld measured only about 40% capture, and the PCWorld retest called surface cleaning the weakest of its five jobs. In a kidney-shaped pool, The Gadgeteer liked how it mowed neat lanes across the surface, and Digital Trends reported no surface problems. Nobody has explained the gap, though debris type and pool shape differ. If floating leaves are why you're buying, keep a net or a separate skimmer.
Heavy, but it waits at the wall
It's about 13kg dry, and PCWorld found it could reach around 20kg straight out of the pool, and couldn't lift it out without getting wet. Digital Trends found it drained fairly quickly if pulled out slowly, but advises smaller or older owners to consider a lighter robot. The good news, PCWorld found, is that it parks at the wall for about 15 minutes, then floats on the surface rather than sinking. The retrieval hook in the box rarely comes out.
Handles obstacles and stairs well
The PCWorld retest watched it approach a hanging ladder, stop, reverse and work round the rungs without getting stuck, something the cheaper Aiper Scuba V3 failed to do in the same pool. Digital Trends expected it to catch on wall jets, as its predecessor had, and it didn't. It also cleaned most stairs, though no robot Digital Trends has tried does them perfectly. In an irregular pool, the navigation is what you're paying for.
Filter, clarifier and the app
The finest standard mesh is 150 microns, which the PCWorld retest says lets some pollen and very fine particles through; a finer basket costs extra. The clarifier cartridges are an ongoing cost, and you reset the counter by hand. The app is detailed, but The Gadgeteer and both PCWorld tests found it can't reach the robot underwater, and The Gadgeteer also wanted a live camera feed. Set it running, then check the log afterwards.
Our take
Should you buy the AquaSense 2 Ultra?
Best for: Pools with curves, steps or shallow sitting ledges. Skip it if: You would struggle to lift a heavy robot out of the water.
The Ultra is worth considering for an awkward pool where sunken leaves and underwater coverage are the main problem, provided you can manage a roughly 13kg dry lift and additional retained water. Camera-guided floor debris collection worked in two PCWorld tests; surface skimming remained mixed. Platforms need at least 35cm of water, and the supplied filter may miss pollen. A lighter V3 has its own ladder and retrieval limitations.
The AquaSense 2 Ultra tops Beatbot's AquaSense 2 line. After a normal sweep of the floor, walls and waterline, a front camera sends it roaming for leftover leaves and back over them. It skims the surface too, cleans shallow platforms, can dose a water clarifier, charges on a dock and parks at the edge when it's done.
All four testers found it excellent underwater. In both PCWorld tests it found nine of ten leaves scattered after a run. It also worked round a hanging ladder that trapped the Aiper Scuba V3 in the same pool. Digital Trends found it mapped accurately and coped with steps and wall jets. Skimming divides them. Both PCWorld tests saw its bow wave push floating leaves away, while The Gadgeteer and Digital Trends were happy with it. It floats at the wall for collection, but PCWorld put its weight near 20kg straight out of the water. The standard filter lets pollen through, the clarifier cartridges are an ongoing cost, and the app can't reach it underwater. Digital Trends calls it overkill for most pools and says the Aiper Scuba X1 Pro Max offers similar features for less.

Before you buy
The questions people ask about this one
Does it skim the surface as well as it cleans underwater?
It tries. PCWorld measured only about 40% capture of floating test debris, and the PCWorld retest also saw leaves pushed away by its bow wave. The Gadgeteer and Digital Trends were happier with it. Don't buy it mainly to skim.
How heavy is it to get out of the pool?
It's heavy. It weighs about 13kg dry, and PCWorld found it could approach 20kg straight out of the water. It parks at the edge and drains through vents, and Digital Trends advises pulling it out slowly so the water runs out first.
Is it cordless, and how long does a charge last?
Yes, and it sits on a contact dock to charge, so there's no cable to plug in, PCWorld notes. Beatbot claims up to 5 hours on the floor and 10 skimming, per the specifications. PCWorld got about 6 hours in the water, and Digital Trends usually managed two custom floor cleans per charge.
Can it cope with steps and a deep end?
Digital Trends found it cleaned most stairs, and the PCWorld retest saw it get round a hanging ladder without sticking. That's two pools, not every depth or step shape. Beatbot specifies at least 35cm of water over platforms, per the specifications, so shallower ledges fall outside that claim.
Will it catch fine dirt and pollen?
Not reliably as supplied. The finest standard mesh is 150 microns, per the specifications, and the PCWorld retest says pollen and very fine particles may pass through. A finer basket is sold separately. None of these tests measured how much the clarifier makes up for the filter.
Does it need an app?
No. Buttons on top start the main modes. The app adds custom programmes and logs, but loses contact underwater, as PCWorld found. The PCWorld retest also noted automatic firmware updates are off by default, so switch them on.
Alternatives
Other robotic pool cleaners to compare.
Scuba V3
Why consider it: It's also camera-guided but far lighter, comes with an ultra-fine filter, and three testers praised its pickup.
The compromise: No skimming, runs are about three hours, and it sinks if you miss its 10-minute pickup window.
AquaSense X
Why consider it: Les Numériques found its station cleared nearly all collected debris from the basket automatically.
The compromise: The station needs space, water, power and drainage, and you still lift the robot onto it.
AquaSense 2 Pro
Why consider it: Tom's Guide France found it particularly good on walls and the waterline.
The compromise: Floating-leaf results are mixed, and it still needs a heavy lift.
AquaSense 2 Ultra head to head
Head to head
Aiper Scuba X1 Pro Max vs AquaSense 2 Ultra
Our verdict: Heise found the Aiper close to the Beatbot on cleaning, and T3 liked its skimming. The Ultra's edge is its camera finding missed leaves on the floor; nobody has shown it skims better. Both are heavy, and the Aiper also failed to finish runs in Reviewed's test. Check current prices rather than assuming a fixed gap.
