A mobile water jet sweep cleaner for movement over surfaces to be cleaned having a housing with a top wall, depending front and end walls and intermediate ribs with bottom opening notches therein. An elongate spray pipe is positioned in the notches and retained therein by caster structures secured to the housing. A brush is on the housing rearwardly of the spray pipe with end portions extending outwardly of the end walls, the lower ends of the brush being normally spaced slightly from the surface to be cleaned. A pipe means communicates with the spray pipe and extends through an aperture in the brush and is connected to an elongate pipe that extends upwardly and rearwardly forming a handle portion terminating any fitting for connection to a conduit for supply of water under pressure. The handle means has a cut off valve with a slide member operatively connected thereto for opening the cut off valve on forward movement and closing the cut off valve on rearward movement. The plurality of nozzles are arranged along the length of the spray pipe and direct fan shaped sprays downwardly and forwardly at an acute angle to the surface to be cleaned providing high pressure jet sprays to sweep debris from the surface as the device is moved forwardly and lowering of the handle portion and engagement of the brush with the surface providing a scrubbing action.
