- Amazon carries older Scuba S1 listings (ASIN B0FJ818NNZ) and this "2026" one; features are similar, but check the title and warranty before buying.
Specs are compiled from manufacturer listings and independent reviews and may change between production runs. Pool robots are re-listed and re-badged often, so confirm on the Amazon page before buying.
The Aiper Scuba S1 (2026) is the best-reviewed budget cordless robot we track: about 870 Amazon reviews on the listing, a 4.4-star average and a price just under $500. It cleans the floor, walls, waterline and shallow areas above 12 inches, uses 11 sensors and a “WavePath” coverage pattern, and carries a 2-year warranty per the listing. For buyers who want a cordless robot with lots of real-world feedback behind it, it’s the safe choice.
Who the S1 is for (and who should skip it)
It’s for you if your budget is about $500, you want waterline and wall cleaning, and you’d rather buy a robot with hundreds of reviews than one in its first season. It suits small to mid-size pools, where a 3-hour cycle is plenty.
Skip it if your pool is large (the listing gives no coverage rating, and the 3-hour battery is shorter than the Sora 10’s rated 5 hours) or if you want AI mapping or surface skimming.
Cleaning and navigation
Eleven sensors feed an adaptive navigation system with “enhanced dual-path algorithms” and the WavePath cleaning pattern, which Aiper says covers the pool systematically with minimal overlap. The four zones it targets are floor, walls, waterline and shallow areas. Caterpillar treads provide traction for climbing. The listing doesn’t list a rated coverage area for the 2026 model, so we leave that blank, but the older Scuba S1 (2024) listing cites about 1,600 sq ft.
Battery and runtime
The listing gives 180 minutes for Auto, Floor, Wall and Scheduled modes and up to 270 minutes in Eco, a floor-only low-power mode. That flexibility is useful: Eco for daily maintenance, full modes for the weekly deep clean. The battery is listed at 112 Wh. See corded vs cordless for how charging fits into a weekly routine.
Filtration
A replaceable 3 µm ultra-fine filter plus a 180 µm standard filter gives you the option of fine filtration without buying a separate kit. Fine filters need rinsing more often than coarse baskets; see maintenance.
Reliability
About 870 reviews average 4.4 stars, which is a meaningful sample for a cordless robot in this price tier, though the 2026 listing is relatively recent and older S1 listings carry their own review histories. Aiper offers a 2-year warranty on this model.
Bottom line
The Scuba S1 is the cordless robot to buy if you want proven, reviewed and under $500. The Sora 10 has a better spec sheet and the S3 has a stronger filter, but the S1 has the owner base. See how it stacks up in our budget cordless comparison.
