A pool cleaner (10) has a chassis, drive wheels (14) that engage containment surfaces of a pool and support the chassis above the containment surfaces, and a pair of circular brushes (16). A drive mechanism receives rotational motion from the drive wheels, and is configured to cause the brushes to counter-rotate with rotation of the drive wheels. A receptacle (48) receives detritus that is swept from the containment surfaces by the brushes. A handle (18) is connected to the chassis, and a user grasps the handle to advance the pool cleaner along the containment surfaces, causing the drive wheels to rotate. |
