Mid-priced cordless pool cleaner with dual-path navigation, dual filtration and waterline scrubbing.
Verdict: A useful mid-price alternative to premium cordless robots. It earns its place on value, though service depth and long-term battery durability deserve scrutiny.
Cordless pool robot for floors, walls, waterline, steps and ledges with backwash filtration.
Verdict: A credible cordless option from an established pool-robot company. The premium buys broader coverage and filtration, but the battery remains a long-term ownership item.
