It works well for medium to large pools thanks to its 31-foot hose, giving it good reach for various pool shapes and sizes.

The cleaner features a large dual-filtration canister that separates big debris from smaller particles, and its transparent lid lets you easily see when it needs emptying, which simplifies maintenance.

Users find it relatively easy to use since no complex assembly is needed, and the scrubbing brushes help with thorough cleaning along all pool surfaces.
