WYBOT S2
#27 in CordlessFull review
For large in-ground pools that need a long runtime on one charge. The C2 is cheaper and enough for pools under about 2,000 sq ft.

3.8/5
A bare-bones cordless floor-and-wall cleaner for budget buyers with smooth above-ground pools. Buyers who want sonar navigation and waterline scrubbing should step up to the Seauto SAT 25.

#30 in CordlessFull review
For in-ground pool owners who never want to lift the robot out to charge it. Anyone happy to plug in a robot can buy the C2 or S2 for much less.
