It's so simple, it's ingenious. To clean you simply roll the top to the floor and return. The internal mechanism deposits the clumped waste into the waste tray, which you then slide out and empty. Your cat can always have clean litter. Saves you money too--no more scoops, liners or filters to buy. Clean litter is never thrown away. Great covered pan design gives privacy to your cat and prevents mess. Works only with clumping litter.
