Cordless Robotic Pool Cleaners
Battery-powered robotic pool cleaners that scrub the floor, walls, and waterline of a swimming pool with no power cord in the water.
 Aiper Scuba S1 | 3.0 Reviewers repeatedly clocked runtime far under the claim and suction too weak to justify the money; Aiper's own cheaper models beat it. | 180 min | 16 lb | 7,800 mAh | ||
|---|---|---|---|---|---|---|
 Aiper Scuba X1 | 5.0 Cleans big debris fine and feels solid, yet testers found it weak on silt and pollen, awkward on steep walls, and heavy to lift out. | 180 min | 26.4 lb | 7,800 mAh | ||
 Beatbot AquaSense 2 | 8.8 Does floor, walls and waterline properly with a genuinely good app and a 3-year replacement warranty, at roughly half what the rest of this field charges. | 240 min | 23.1 lb | 10,000 mAh | ||
 Beatbot AquaSense 2 Ultra | 7.8 The best hardware and navigation here, but at two to three times the price of the standard AquaSense 2 for gains most pools will never notice. | 300 min | 29.1 lb | 13,400 mAh | ||
 Dolphin Liberty 400 | 6.0 Dependable Maytronics basics and easy handling, but no app, one short cycle per six-hour charge, and a sealed battery at $1,099. | 150 min | 17.9 lb | 10,400 mAh | ||
 Polaris FREEDOM | 7.0 Premium build and refined navigation from a real pool brand, held back by flaky underwater connectivity and a price that undercuts nothing. | 150 min | 20 lb | 9,600 mAh |
How the AI score works, and who wrote it
A language model rated these, not a test lab. Every score from 1 to 10 is an AI assessment of how good the product is against the other 6 in this comparison, formed from the specifications we verified plus the published lab reviews and owner reception found while researching each one. Nobody at Slopsheets listened to, wore or plugged in any of it.
It weighs the things a spec table cannot show: how a product is actually reviewed, how well the software works, build quality, and what you get for the money. That is deliberate. An earlier version of this column was pure arithmetic on the table and it ranked a bundle of cheap boxes above a class-leading single unit, because counting hardware is not the same as judging it.
Treat it as an informed starting point and read the sourced comparison, not as a verdict. The score is relative to this comparison only, so it means nothing across categories, and it carries no price, star rating or review count. Every specification behind it is sourced and checked; the score on top of them is opinion.
