Abstract
Abstract A device for cleaning the sidewalls of a swimming pool at the waterline region is self-propelled by water jets which also urge the device against the pool sidewall. The device includes brushes which brush against and clean the sidewall of the swimming pool as the device advances through the water. Means are provided for squirting a cleaning agent against the tiles. In one embodiment, means also are provided for collecting debris and dirt loosened by the brushes.
