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.
Premium all-in-one cordless pool robot with mapping, 8,500 GPH filtration and surface parking.
Verdict: Broad coverage and high flow make it a genuine flagship competitor, but buyers should weigh the premium against Aiper's shorter track record and frequent promotional pricing.
