Seauto Crab
#21 in CordlessFull review
Skip it: independent testing found poor debris pickup. Any WYBOT C1 or Aiper at a similar price is a safer bet.

Seauto SAT20
#34 in CordlessFull review
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.
