Surface cleaning machine having double glide apparatus

Abstract

A surface cleaning machine includes a cleaning head having a double glide apparatus formed by a first glide member in front position and a second glide member in rear position. The first and the second glide members are joined together along a portion of their facing walls, a longitudinal cavity being defined therebetween that opens to the surface to be cleaned. Each of the first and the second glide members has one or more suction openings defined in its bottom wall, and the second glide member also has one or more inlet openings defined in its rear wall to receive a cleaning solution, which is delivered through the cavity to a surface to be cleaned and is removed from the surface by action of vacuum applied through the suction openings.

Description

FIELD OF THE INVENTION[0001]The present invention concerns a surface cleaning machine, which includes a cleaning head having a double glide apparatus formed by a first glide member in front position and a second glide member in rear position. More specifically, the present invention concerns a cleaning machine, by which a cleaning solution is applied through a cavity within the double glide apparatus to a surface to be cleaned and is then removed by the action of vacuum applied at each of the first and second glide members.BACKGROUND OF THE INVENTION[0002]Surface cleaning machines, in particular carpet cleaning machines, typically include a nozzle spraying a cleaning solution onto a surface to be cleaned, and a vacuum system extracting the spent cleaning solution and dirt particles from the surface. Examples of floor cleaning machines in the prior art are disclosed in U.S. Pat. No. 3,624,668 to Krause; U.S. Pat. No. 4,441,229 to Monson; and U.S. Pat. No. 7,530,135 to Benedict.[0003]...

AI Technical Summary

Benefits of technology

[0012]It is an aspect of the present invention to provide a surface cleaning machine that improves cleaning effectiveness and speed.

[0013]It is another aspect of the present invention to provide a surface cleaning machine that reduces the cost of cleaning a surface such as a carpet.

[0014]It is still another aspect of the present invention to provide a carpet cleaning machine having a double glide apparatus, in which a front glide member applies vacuum to the pile before the cleaning solution is applied, causing the carpet pile to become more erect and better exposed to the cleaning solution, and a second glide member removes the spent cleaning solution and dirt particles entrained therein from the carpet pile.

[0015]It is still another aspect of the present invention to provide a carpet cleaning machine with a double glide apparatus, which leaves the carpet pile erect and, therefore, substantially uniform after cleaning, reducing or eliminating the need to comb of the carpet to achieve a uniform look.

Problems solved by technology

Limitations of surface cleaning machines in the prior art include the limited efficiencies deriving from cleaning a carpet pile that is often not erect, especially in the case of long piles; and the need to comb the carpet after cleaning to provide the uniform look expected by the purchasers of floor cleaning services.
