Abstract
A rug cleaning head for a traditional rug cleaning application machine is improved. The spray apparatus remains prior art. The vacuum components on the underside of the cleaning head are improved with a focusing diverter arm or a pair of arms forming a “V”. The arm or arms direct the wash water into a reduced size (about a one inch slot) vacuum inlet. The result is much more wash water is collected from the rug due to the combination of a higher speed (reduced size) vacuum inlet stream and the focusing diverter's urging all the wash water into the smaller vacuum inlet. An alternate embodiment uses separate spray/vacuum inlet assemblies on a star shaped hub.
Claims22
A rotary carpet cleaning head comprising:
- a plate shaped base having a top surface and a bottom surface;
- said plate shaped base having a connection for a powered hub which rotates the plate shaped base;
- a plurality of wash water spray nozzles attached to the plate shaped base which when in use spray wash water into a carpet to be cleaned;
- a first diverter arm attached to the bottom surface behind a first wash water spray nozzle so as to form an acute angel smaller than or equal to about 85° relative to a radius axis from a center of the plate shaped base through a vacuum inlet;
- said vacuum inlet cannot extend beyond the first diverter arm;
- said first diverter arm located between the center of the plate shaped base and the vacuum inlet and the acute angle measured inbound from the first diverter arm;
- said first diverter arm extending from the first wash water spray nozzle to the vacuum inlet;
- said first diverter arm having a height to rest on the carpet to be cleaned, wherein a support for a weight of a powered applicator machine is supported by the first diverter arm;
- and
- said vacuum inlet has an opening cross sectional area of less than about one half a square inch.

A rotary carpet cleaning head comprising:
- a rotating spray and vacuum inlet assembly;
- said assembly having a connection means to a powered hub functioning to allow the powered hub to rotate the assembly;
- a wash water spray nozzle attached to the assembly which when in use sprays wash water into a carpet to be cleaned;
- a V shaped focusing diverter having a height to rest on the carpet to be cleaned;
- wherein said V shaped focusing diverter diverts wash water from the wash water spray nozzle from a point inbound and along a radius of the cleaning head and from the wash water spray nozzle and a point at a periphery of the cleaning head into a vacuum inlet on the assembly as the assembly is rotating in use;
- said vacuum inlet sized to be equal or less in length than a distance between an inner edge of a pair of arms at a top nozzle end of the V shape of the V shaped focusing diverter means;
- and
- wherein a support for a weight of a powered applicator machine is supported by the V shaped focusing diverter.
