Abstract
Abstract A cleaning apparatus having a pan-shaped housing carrying brushes engageable with a surface to be cleaned. Mounted on the top of the housing is a spinner assembly having a body containing a longitudinal passage. A tubular shaft rotatably mounted in the passage carries tubular arms located within the housing. The fluid flows from the hollow shaft into the arms and is discharged through the orifices in nozzles mounted on the ends of the arms. The shaft has a head located in a chamber at one end of the passage. The diameter of the head is larger than the diameter of the passage and is dynamically balanced by the flow of fluid under pressure through the passage and chamber into the hollow shaft. A guard carrying a center brush attached to the housing protects the arms and nozzles of the spinner assembly.
