How to choose
Walls, waterline and floor coverage
Coverage differs most on walls and waterlines. The PoolMr cleans edges and corners near the wall with a boosted suction mode, and climbs slopes up to 15 degrees. Match the coverage to the surfaces that gather debris in your pool, not just the floor.
Runtime, battery and cordless use
Runtime decides how much pool gets cleaned on one charge. The WYBOT runs 120 to 160 minutes, the CZYBYTE and PoolMr run 120 minutes, and the ROBOKLEEN runs 100 minutes. The Dolphin is not a battery model: it plugs in and cleans in 1.5 hours.
Filters, baskets and fine debris
Filter mesh and basket size decide what stays trapped. The CZYBYTE holds 4L with a 150μm mesh, the ROBOKLEEN holds 0.28 cu ft with a 180μm mesh, and the WYBOT and PoolMr use 180μm mesh filters. The PoolMr adds a dense cotton sponge as a second layer, and its anti-return technology holds debris inside when lifted. Top-load baskets on the CZYBYTE, WYBOT and Dolphin make debris removal straightforward.
