Abstract
Robotic apparatus cleans swimming pools and has road and pulley wheels with belts thereon, on opposite sides and drive motors that rotate a wheel on each side to move the frame along a pool surface. Pairs of outside wheels have friction surfaces to engage pool surfaces to also moving the frame. Forward and rearward brush assemblies are driven to brush the pool surface. Oppositely facing and angled duck bill valves allow water into free volumes in the frame and are covered by a filter bag for filtering out debris under the action of a dual pump assembly that pumps water out through a pair of outlet opening in a top of the frame. A computer processor controls the drive motors and pump assembly to move the frame along programmed paths and rechargeable batteries power the drive motors, pump assembly and computer processor.
