Three cordless robots sell for $400–$500 and clean floor, walls and waterline: the Beatbot Sora 10, the Aiper Scuba S1 (2026) and the Wybot C1. They look similar on a spec sheet, but the details (battery, coverage, filtration and track record) separate them. This comparison uses listing data and manufacturer tables as of October 2026; for how the scores work, see how we research.

Cleaning and navigation
All three clean the same four zones. The Sora 10 reaches shallow areas down to 12 inches and parks at the waterline. The Scuba S1 uses 11 sensors and a “WavePath” pattern, and reaches shallow areas above 12 inches. The C1 uses gyroscope navigation with N- and S-path patterns and has a triple-motor climbing system. None has AI mapping.
Battery and coverage
The Sora 10’s 300-minute rating and 3,229 sq ft figure are far above the others: nearly double the S1’s auto runtime and twice the C1’s rated coverage. Rated figures are best-case (see coverage ratings explained), but the gap is real. If your pool is over about 1,000 sq ft, the C1’s battery is the limiting factor. For a typical 16×32 pool, any of the three is enough.
Filtration
The S1’s dual filter with a 3 µm ultra-fine option is the best of the three for fine dust and pollen. The Sora 10 has a bigger 5 L basket (good for leaves) and an optional 3 µm filter. The C1 has a dual-layer basket. See filtration microns explained.
Reviews and reliability
The S1 has the best numbers: about 870 reviews at 4.4 stars. The C1 has the most reviews (about 1,040) but a lower 4.0 average. The Sora 10 is the newest; its small review base makes it the riskiest on paper, though it has the strongest specs. All three give a 2-year warranty.
Which one should you buy?
Buy the Sora 10 if you want the best specs per dollar and the largest pool rating, and you’re comfortable with a newer robot.
Buy the Scuba S1 if you want the proven option with the best reviews and fine filtration.
Buy the Wybot C1 if your pool is small (under about 1,600 sq ft) and every dollar matters.
