Beatbot AquaSense 2 Ultra

The AquaSense 2 Ultra is Beatbot's camera-guided cordless robot for big, complicated pools: large freeform shapes, several depth levels, lots of debris. Beatbot rates it for up to 3,444 square feet of pool floor in one cycle, and it covers the floor, walls, waterline and surface, with a built-in dispenser for its clarifying agent. It is the upgrade pick in Reviewed's 2026 guide and earned PCWorld's Editors' Choice.

It is for owners who want the most automation a cordless robot offered in 2025 and 2026, and who are fine lifting a heavy machine out of the pool after each run.

Long run time. Beatbot lists up to 5 hours on the floor, 4.5 hours on walls and waterline and 10 hours on the surface from a 13,400 mAh battery. PCWorld measured about 6 hours, beyond the spec, and saw its test pool cleared of debris in roughly 3 hours. That is enough to clean even a large pool in one charge.

Camera-guided cleaning. Beatbot's HybridSense system combines an AI camera with dual time-of-flight, infrared and ultrasonic sensors, 27 in all. In PCWorld's test it spotted and collected 9 of 10 scattered leaves by sight, and the app shows a pool map and the cleaning path after each run.

It comes to you. When the cycle ends or the battery drops below 15 percent, it drains its internal water, floats up and parks at the wall. Reviewed could retrieve it without getting wet, and PCWorld notes it switches to free floating if you do not collect it right away.

Big baskets and a real warranty. Two baskets hold 7.7 liters in total, the most capacity on our list, and Beatbot backs the robot with a three-year full-replacement warranty, three times the term Maytronics now lists for its Nautilus models.

Clearer water. Reviewed reports sparkling water within hours when the ClearWater clarifier was in use. The clarifying agent is sold separately.

Weight. It weighs 29.1 pounds dry, and PCWorld estimates about 45 pounds with water inside if you pull it before it drains. Reviewed calls the weight a possible deal breaker for owners without much upper-body strength, and you lift it after every charge.

Surface skimming is weak. PCWorld found it captured only about 40 percent of floating test debris because its bow wave pushed material away. If floating leaves are your main problem, the Beatbot Sora 70 did much better in the surface tests we read, or pair a robot with a dedicated skimmer.

Steps and ledges. Reviewed saw it miss dirt on the shallow tanning area at the top of the steps. Beatbot says platform cleaning needs at least 13.7 inches of water and steps need more than 1.31 feet.

Coarse filtration for the price class. The baskets stop at 150 microns. The Pool Nerd, which disapproves of it, describes the filter as two thin mesh layers and reports suction that seemed to fade as the battery drained. The corded Dolphin Nautilus CC Plus Wi-Fi filters down to 70 microns.

Running costs and connectivity. Clarifier refills are an ongoing cost, and like every pool robot it loses Wi-Fi underwater, so remote control only works at the surface. Beatbot's newer AquaSense X adds a self-cleaning dock, so this is no longer the top of the range.

The Beatbot Sora 70 delivers most of the same coverage (floor, walls, waterline, surface) without the camera, clarifier or dual baskets. It reaches shallower ledges, weighs about six pounds less and sits a price class lower. PCWorld's Sora review says the AquaSense line is the stronger performer if budget allows, while Reviewed found the Sora cleaned steps and a Baja shelf that the Ultra could not.

The corded Dolphin Nautilus CC Plus Wi-Fi runs on a weekly timer with a finer filter and no charging, but skips the waterline, surface and steps. See the best robot pool cleaners for the full comparison.

Buy the AquaSense 2 Ultra if you have a large or multi-level pool, want the longest cordless run time and camera-guided cleaning, and value a three-year replacement warranty. Skip it if lifting close to 30 pounds after every run is a problem, if your pool has a big tanning ledge, or if you mainly need surface skimming; the Sora 70 or a corded Dolphin is the better fit.
