Rotary surface cleaning tool

Abstract

A rotary surface cleaning machine for cleaning floors, including both carpeted floors and uncarpeted hard floor surfaces including but not limited to wood, tile, linoleum and natural stone flooring. The rotary surface cleaning machine has a rotary surface cleaning tool mounted on a frame and coupled for high speed rotary motion relative to the frame. The rotary surface cleaning tool has a substantially circular operational surface that performs the cleaning operation. The rotary surface cleaning tool is driven by an on-board power plant to rotate at high speed. The rotary surface cleaning tool is coupled to a supply of pressurized hot liquid solution of cleaning fluid and a powerful vacuum suction source.

Description

FIELD OF THE INVENTION[0001]The present invention relates generally to a rotary tool for cleaning surfaces, including rugs and carpets, and in particular to such apparatus and methods with brushes for coaction with cleaning liquid delivering means and suction extraction means.BACKGROUND OF THE INVENTION[0002]Many apparatuses and methods are known for cleaning carpeting and other flooring, wall and upholstery surfaces. The cleaning apparatuses and methods most commonly used today apply cleaning fluid as a spray under pressure to the surface whereupon the cleaning fluid dissolves the dirt and stains and the apparatus scrubs the fibers while simultaneously applying suction to extract the cleaning fluid and the dissolved soil. Many different apparatuses and methods for spraying cleaning fluid under pressure and then removing it with suction are illustrated in the prior art. Some of these cleaning apparatuses and methods use a rotating device wherein the entire machine is transported ove...

AI Technical Summary

Benefits of technology

This patent describes a rotary surface cleaning tool that uses a spiral pattern of spray nozzles to deliver cleaning solution to the floor. This pattern reduces the number of individual spray nozzles needed, which saves money but ensures sufficient cleaning solution delivery. The cleaning tool also includes rows of bristle brushes that provide a more aggressive cleaning action when combined with fluid cleaning. Additionally, the tool can be used on both carpet and hard floor surfaces without causing any damage. The tool's design allows for uniform pressure across the entire radius of the cleaning tool.

Problems solved by technology

The spray nozzles are very expensive to drill or otherwise form because they are only about 1 / 10,000th of an inch in diameter.
