Benefits of technology

"The present invention is an improved floor cleaning device that includes a base and a handle. The base has a suction nozzle and a brush assembly for agitating the surface. The brush and nozzle can be raised off the surface for vacuuming or lowered to contact the surface for collecting and picking up liquid and dirt from the surface. The device can also be moved along the surface to collect and pick up particles and cleaning solution. The technical effect of this invention is to provide a floor cleaning device that can efficiently pick up loose particles and cleaning solution from the surface."

Problems solved by technology

Such floors are of a relatively unyielding and nonabsorbent nature.

Embodiment Construction

[0081] Referring to the drawings, FIG. 1 depicts a perspective view of an upright hard floor-cleaning unit 40 of one embodiment of the present invention. The hard floor cleaning unit 40 comprises an upright handle assembly 42 pivotally connected to the rear portion of a base assembly 44 that moves and cleans along a surface. In particular, as shown in FIG. 2C, a pair of trunnions 46, laterally extending from respective right and left ears 48, 49 integrally formed on the lower end on the handle assembly 42, journal into caps 50 mounted on the rear of the frame 52 of the base assembly 44 to form the pivotal connection. Referring back to FIG. 1, the base assembly 44 includes a nozzle assembly 62 for recovery particles and / or fluid from the floor and a brush block assembly 216 (FIG. 2A) for scrubbing the floor. The handle assembly 42 includes a recovery tank 53 for collecting the particles and / or fluid picked up by the nozzle assembly 62 and a solution tank 43 containing cleaning soluti...

Abstract

A floor cleaning device comprises a base portion for movement along a surface and a handle portion pivotally connected to the base. The base portion further includes a suction nozzle and a brush assembly for agitating the surface, wherein the brush assembly and the nozzle assembly are in a first position raised off of the surface for vacuuming the surface, and the nozzle assembly is lowered to a second position contacting the surface for collecting and picking up liquid and dirt from the surface. A method of cleaning a surface by first dry vacuuming the surface using a cleaning unit in which the nozzle assembly is raised to pick up particles and then wet vacuuming the floor with the nozzle assembly lowered to collect and pick up dirt from the floor mixed with cleaning solution distributed on the floor.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to a cleaner such as a hard floor cleaning unit for use in wet or dry cleaning modes. In particular, the present application pertains to such a hard floor cleaning unit having a nozzle assembly that is raised off the floor for use in the dry cleaning mode and lowered on the floor for use in the wet cleaning mode. [0003] 2. Background Information [0004] It is known in the prior art to provide a hard or bare floor cleaning unit. Such floors are of a relatively unyielding and nonabsorbent nature. Some examples of these floors include ceramic tile, sealed hardwood, concrete, and vinyl. For these floors, it is often desirable to have a multipurpose cleaning unit which can be selected and used to dry vacuum the floor to pick up dirt and dust, or wet vacuum the floor by scrubbing the floor with cleaning solution and then collecting and picking it up. Also, it is desirable to first dry vacuum t...
