Abstract
Abstract A cleaning apparatus having a pan-shaped housing enclosing a rotatable spinner assembly equipped with a plurality of rotatable laterally directed arms for carrying cleaning fluid under pressure to nozzles. Cleaning fluid under pressure is discharged in a circular pattern out the open side of the housing close to the surface to be cleaned. Brushes connected to the housing scrub the surface as the apparatus is moved over the surface. A pair of facing housings are adjustably mounted on a frame used to change the elevation of the housings. One of the frames is adjustably mounted on a support so that the space between the housings can be changed. A plurality of caster wheels and a handle may be connected to a housing so that the apparatus is movably supported above a surface.
