Frequently asked questions
Corded or cordless — which is better?
Corded cleaners run as long as you like and never need charging; cordless models are easier to drop in and retrieve with no cable to untangle.
Does it clean walls and the waterline?
Models with waterline scrubbing climb the walls and clean the tile line where oils and scum collect, not just the floor.
Do I still need a separate pool filter?
The robot has its own filter basket/cartridge for debris; it reduces load on your main system but doesn’t replace water chemistry and circulation.
