OYEMIA SAT25
Inground pools up to about 2,150 sq ft that want cordless floor, wall, and waterline cleaning
Up to 180 minutes after about a 4-hour charge. Floor, walls, and waterline.
2026 lineup
Pool robots worth dropping in the water
Most roundups sort by price and stop. This one sorts by the job: pool size, cord versus battery, and whether the waterline is actually on the spec sheet. The featured cordless pick is the OYEMIA SAT25.
Beatbot
Beatbot AquaSense 2
Larger inground or above-ground pools where retrieval and waterline scrubbing matter more than a light carry
Dolphin
Dolphin Nautilus CC Plus
Inground pools that want a proven corded scrubber and do not mind a floating cable
The whole lineup, without the prices
Prices change by the hour, so every button goes to Amazon instead of a number we would have to keep lying about. The SAT25 leads because its listing matches a normal inground pool. The Dolphin and Beatbot are here because owners have already lived with them. DEENO's corded machines are further down: useful for a specific dirty-pool job, not the default.

When the robot misbehaves
A pool robot that will not climb, will not sink, or parks on the drain is usually a setup problem before it is a dead motor. Fix-it guides publish every other day from November 6, 2026.
