Abstract
The present invention is a water-powered device for cleaning gutters and the like. An elongated housing includes a water-powered motor comprising an internal paddlewheel mated to a first end of a gear train. A fitting is attached to a first end of the housing. The fitting is connected to a conventional hose to provide a stream of water to the paddlewheel. A drive gear is mated to a second end of the gear train. Drums having cleats are mounted to the gear train. As the water rotates the paddlewheel, the gear train reduces the rotational speed and increases the torque delivered to the drive gear and the drums. As the drums rotate and mulch debris in the gutter, the device advances forward. Water is flushed from the housing through specially oriented ports into the gutter to enhance the mulching of debris.
