Embodiment Construction

[0040] now refer to Figure 1-4 , shows an upright extraction cleaning device, generally indicated at 10 , according to an aspect of an exemplary embodiment. The extraction cleaning device 10 generally includes a base assembly 11 and a handle assembly 12 for engaging a floor surface, such as carpet or hard floors. The handle assembly 12 is pivotally connected to the base assembly 11 and can be hinged in a generally upright position (in Figure 1-4 shown in ) and oblique or angled orientations.

[0041] now refer to Figure 5 , the base assembly 11 includes a main body 13 that supports and carries various parts installed in the base assembly. A handle release lever 14 is carried by the body 13 and can be depressed by a user to release the handle assembly 12 from the upright position. The body 13 also includes a pair of opposed hubs 15 each adapted to receive a pin 16 therein. Each pin carries a wheel 17 which is rotatably mounted thereon. One or more sensor systems 18 may...

Abstract

An extraction cleaning apparatus includes separate cleaning tanks for water and detergent and optionally also for rinse agent. The apparatus is able to sense its direction of travel and / or rate of travel and to control the cleaning liquid composition and / or rate of its delivery onto the floor in accordance therewith. For example, the apparatus is able to dispense detergent at a higher rate when the forward rate of travel increases and to dispense only water and / or rinse agent in the reverse direction.
