Our take
The WYBOT S2 Cordless Robotic Pool Cleaner is a cordless, battery-powered robotic pool cleaner from Wybot. It cleans the floor, walls and waterline, navigates in a systematic pattern rather than at random, using 6 cleaning paths (S-pattern default), and pairs with its app over Bluetooth. A charge lasts up to 210 minutes and takes about 3 hours to refill.
On paper it scores 8.1 out of 10 (great) against other robotic cleaners. Its strongest areas are runtime (10.0) and pool size (10.0). Where it gives ground: app & connectivity (6.0) and filtration (6.5).
The best price we found is $759.99 at WYBOT, 24% off its $999.99 list price. The typical robotic cleaner we track costs $899, so this one is cheaper than most. For what it does, its value score is 7.3 out of 10.
If you want mapping navigation, the cheapest we track with it is the Dreame Z1 Cordless Robotic Pool Cleaner at $349.99.
If you want a Wi-Fi app, the cheapest we track with it is the Dreame Z1 Pro Cordless Robotic Pool Cleaner at $399.99.
To spend less for nearly the same spec score, the WYBOT C2 Cordless Robotic Pool Cleaner (2026 Upgrade) rates 8.4 for $429.
For about the same money, the Beatbot AquaSense 2 Robotic Pool Cleaner scores higher (9.0) at $799.
Bottom line: a great pick for pools with no outlet near the deck, large pools, above-ground pools and buyers who want the most features per dollar.
