Abstract
A drive system for a pool cleaner is disclosed, the drive system including a motor operatively connected relative to an axle for driving rotation of the axle. The axel in turn is connected to and drives the rotation of (i) a roller assembly including a roller for cleaning a target surface and (ii) a wheel drive assembly engaged with an idler gear for driving a wheel. Notably the axis of rotation of the roller assembly is different than the axis of rotation of the wheel. Thus, the wheel drive assembly may drive the wheel by interacting with a surface of a cylindrical flange of the wheel.
