Carpet cleaning apparatus and method of construction

Abstract

A carpet cleaning apparatus and method of retrofitting a vacuum cleaner provides a vacuum cleaner with a sweeper housing carrying a rotating brush assembly for contacting a surface of a carpet. A collection device is carried in the sweeper housing along with a fan assembly. A suction hose is connected in circuit with the fan assembly and the collection device. A pump driven vessel is carried externally to the sweeper housing for fluid communication with a spray nozzle. The spray nozzle is arranged externally to the housing to dispense fluid under pressure a spaced distance from the housing.

Description

REFERENCE TO CO-PENDING APPLICATION [0001] This application claims the benefit of U.S. Provisional Application No. 60 / 515,518, filed Oct. 29, 2003.BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] This invention relates generally to vacuum apparatuses for cleaning carpet, and more particularly to vacuum apparatuses having mechanism for spraying a treatment liquid onto carpet. [0004] 2. Related Art [0005] Typically, over time, carpet requires an application of an odor eliminator, a protectant and / or a vacuum enhancement product. Commonly, odor eliminators, carpet protectants and vacuum enhancement products come in a liquid state, and are applied by a user through the use of aerosol cans, spray bottles and the like. As such, the user typically carries a hand held container with the desired liquid treatment therein, and applies the liquid treatment by bending at the waist to dispense a spray pattern of the liquid onto the area of the carpet requiring treatment.

AI Technical Summary

Benefits of technology

[0006] A carpet cleaning apparatus provide an easy and efficient manner in which to apply liquid carpet treatment products on carpet to facilitate cleaning the carpet without saturating the carpet. The apparatus has a sweeper housing carrying a rotating brush assembly for contacting a surface of a carpet. A collection device is carried in the sweeper housing along with a fan assembly. A suction hose is connected in circuit with the fan assembly and the collection device. A pump driven vessel is carried externally to the sweeper housing for fluid communication with a spray nozzle. The spray nozzle is arranged externally to the housing to dispense fluid under pressure a spaced distance from the housing.

[0008] Some of the objects, features and advantages of the invention include an apparatus that increases the usefulness and efficiency of a standard upright vacuum cleaner, applies a liquid treatment uniformly to a carpet while vacuuming the carpet, is readily attachable to a vacuum cleaner, is of relatively compact size, is readily removable from the vacuum cleaner, enables the application of liquid cleaner to difficult to reach areas of a carpet, regulates the amount of liquid cleaner being applied to the carpet, dispenses liquid cleaner in a controlled pattern, and is economical in design, manufacture and use.

Problems solved by technology

Accordingly, the application of a liquid carpet treatment product generally proves to be laborious and tiresome, let alone time consuming.

In addition, applying a uniform spray of the liquid carpet treatment product can prove difficult.
