First Claim
1. A carpet extractor having a source of cleaning solution for selective depositing upon a carpet and a vacuum source for extracting the cleaning solution with entrained dirt from the carpet and further comprising;
- a main body having a pair of vertical guide slots;
support means for supporting said main body above the floor being cleaned;
a brush support beam having a pair of rails extending therefrom;
each of said rails being slidably received within an associated one of said vertical guide slots;
a plurality of brushes carried by said beam;
each of said brushes engaging the surface being cleaned;
said brushes being freely floating with said support beam within said guide slots upon the surface being cleaned; and

Abstract
Floor care apparatus is disclosed wherein a powered brush assembly having a multiplicity of rotary brushes is suspended within the apparatus such that the brush assembly floats freely upon the surface being cleaned without supporting any of the machine'"'"'s weight. The rotary brushes are generally configured as spur gears and function in a gear train wherein one brush drives all other gear brushes in the system. Axially projecting brush bristles are embedded in each gear tooth such that there is no unbrushed area between adjacent brushes in the brush line. The portion of the gear tooth wherein the bristles are embedded includes a recessed profile to allow for circumferential expansion of the tooth, upon insertion of the brush bristles, thereby preventing gear tooth interference. The brush assembly is particularly suitable for hot water carpet extractors of the upright design.

4. A carpet extractor cleaning apparatus, comprising:
-
a source of cleaning solution for selectively depositing cleaning solution upon a carpet; a vacuum source for extracting the cleaning solution from the carpet; a main body receiving one of said source of cleaning solution and vacuum source, said main body having guide slots therein; said main body having a rear support and a forward support; at least one brush slidingly received in a bearing in a brush support beam such that said brush is free to move vertically within said bearing with respect to said support beam; said support beam is movably received by vertical guide slots in said main body such that said support beam may translate vertically with respect to said main body and in both parallel and skewed relationship with respect to said main body such that said brush freely floats upon the surface being cleaned without supporting any of the weight of said main body; and wherein said at least one brush comprises a plurality of brushes suspended from said brush support beam such that each of said plurality of brushes is free to move vertically with respect to said support beam and with respect to each other. - View Dependent Claims (5, 6, 7, 8, 9, 10, 11)
