Abstract

A portable cleaning apparatus may include a handle and a wheel rotatably mounted to the handle. Pressurized fluid may enter the apparatus, and a fluid flow director directs the fluid to scrubbing elements to rotate the wheel. The scrubbing elements may be secured to the wheel, and different types of treatment material dispensing systems are operable to apply treatment material to the scrubbing elements.

Claims (30)

1. A portable apparatus for treating a surface and comprising:

a handle having a proximal portion for holding in a person's hand and a distal portion for delivering a mobilizing fluid to the surface;

a fluid supply fitting at the proximal portion for connection to a source of mobilizing fluid;

a housing at the distal portion of the handle;

a nozzle at the housing, said nozzle having an inlet to receive said mobilizing fluid, and said nozzle having an outlet to discharge said mobilizing fluid in a direction;

a wheel mounted in the housing for rotation on an axis in the housing; and

a mobilizing fluid delivery passageway from said supply fitting to said nozzle inlet; and wherein:

said nozzle is movable from one orientation to another orientation to change discharge direction of said mobilizing fluid from said nozzle outlet relative to said axis, the apparatus further comprising:

a plurality of surface treating elements circularly spaced around the wheel,

wherein said surface treating elements have a front face and a back face bordered by edges and are mounted on said wheel and pivotal between an extended outward condition relative to said axis with said back face oriented facing said nozzle when said nozzle is in said one orientation, and a collapsed condition upon impact with a surface being treated, said surface treating elements being supported by stops on said wheel engage-able by said front face of said surface treating elements to prevent said surface treating elements from being collapsed by impact of said fluid impingement from said nozzle on said back face.

2. The apparatus of claim 1 and wherein:

said nozzle has a deflector plate portion which has a rear end and a front end, said rear end at said nozzle inlet and said front end facing said wheel;

said nozzle has a cap portion covering said plate portion and which has a rear end and a front end, said rear end at said nozzle inlet and said front end facing said wheel;

said deflector plate portion having a top surface receiving said mobilizing fluid entering said housing from said passageway, and directing said received fluid toward said wheel above said axis when said nozzle is in said one orientation; and

said deflector plate portion having a bottom surface receiving said mobilizing fluid entering said housing from said passageway when said nozzle is in said another orientation and directing said received fluid toward said wheel below said axis.

3. The apparatus of claim 2 and further comprising:

sidewalls above and below said deflector plate portion.

4. The apparatus of claim 3 and wherein:

said sidewalls flare out from said rear end of said deflector plate portion to said front end.

5. The apparatus of claim 4 and wherein:

said cap portion converges toward said deflector plate portion from said rear end of said cap portion to said front end of said cap portion.

6. The apparatus of claim 1 and wherein:

said wheel is adapted to reverse installation in said housing to place said back faces oriented facing said nozzle when said nozzle is in said another orientation to establish another mobilizing fluid discharge direction to impinge said surface treating elements below said axis of rotation and thereby rotate said wheel in a rotational direction opposite said one rotational direction.

7. The apparatus of claim 1 and wherein:

said nozzle is spring loaded for stabilization of said nozzle in said one orientation and, alternatively, in said another orientation.

8. The apparatus of claim 1 and further comprising:

a treatment material dispenser configured to be moved from a first position outside the housing to a second position at least partially inside the housing; and

a cam operable to selectively move the treatment material dispenser between the first and second positions.

9. The apparatus of claim 1 and, further comprising:

a high pressure water washer device coupled to said handle to deliver pressurized water to said nozzle.
