Aiper Scuba S1
Best for: Simple rectangular in-ground pools up to 1,600 sq ft
Our verdict
Buy the Scuba S1 for a simple, rectangular in-ground pool up to 1,600 sq ft where you mainly need the floor and walls cleaned. If your pool has steep transitions, many drains or steps, or you want the waterline scrubbed, the Scuba X1 or Beatbot Sora 10 is the safer choice.
The Aiper Scuba S1 is the robot most people search for when they start shopping for a cordless pool cleaner. It is light, simple and cleans both the floor and the walls. We have not tested it ourselves; this review compares Aiper's published specifications with independent reviews and owner reports (see sources), as explained in how we research.
What the Scuba S1 does
According to Aiper's specification table, the S1:
- cleans the floor and walls of in-ground pools up to 1,600 sq ft and 50 ft long;
- moves 4,200 gallons per hour through a 180 µm basket plus a 3 µm MicroMesh filter, with a 3.5 L capacity;
- runs up to 180 minutes and recharges in 3 to 4 hours with the DC charger (solar charging is optional);
- offers Floor, Wall and Automatic modes, plus Eco schedules of 45, 60 or 90 minutes several times a week;
- navigates with WavePath 2.0, which uses motion sensors rather than obstacle sensors.
Tip: Aiper has sold 2024, 2025 and 2026 versions under the same name. Its own page lists runtimes of 150, 180 and 270 minutes in different places. Check the serial number or the device info in the Aiper app to know which version you have.
Where it falls short
The most consistent complaint in owner reports is getting stuck. A Trouble Free Pool owner describes the robot stalling on the slope between the shallow and deep end until the battery dies; another reports it snagging on drains before freeing itself. Poolbots' review says it catches on steps, drain covers and liner wrinkles.
That fits the hardware: the S1 has one active roller at the front and no obstacle sensors. Simple rectangular pools with gentle slopes suit it best.
Who should buy it
- Buy it if your in-ground pool is rectangular, up to 1,600 sq ft, with gentle slopes, and you mainly need floor and wall cleaning.
- Skip it if your pool has a steep drop, a main drain the robot keeps catching on, or you want the waterline scrubbed.
Better alternatives for tricky pools
If your pool is larger or more complex, two robots stand out on paper:
Aiper
Aiper Scuba X1
Best for: Larger in-ground pools that need waterline cleaning
Beatbot
Beatbot Sora 10
List price $699 (as of Oct 2026)
Best for: Medium to large in-ground or above-ground pools on a budget
Bottom line
The Scuba S1 earns its popularity as a simple floor-and-wall cleaner, and the 3 µm filter on current versions is a real plus. Its lack of obstacle sensors is the deciding limitation: in the right pool it is good value; in the wrong one it will need rescuing.
