Abstract
Abstract An improved apparatus, particularly applicable for shampooing corners of wall-to-wall carpeting comprises an elongated, hand gripped shaft in two segments structured to allow the apparatus to be pointed into the corners of such carpeting, a container secured to the shaft to store shampoo for use in the apparatus; a rotatable brush secured to the shaft acting to contact and clean the carpeting; and a conduit providing shampoo from the container to the brush. A system which allows the operator to control when and how much shampoo is released from the container is also disclosed.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
126 words
An apparatus for manually treating a floor comprising in combination an elongated hollow shaft bent near one end at an obtuse angle to form a handle portion at said end for a user to hand operate said apparatus; a container removably secured to said shaft for storing cleaning liquid therein; an electric motor secured axially to the other end of said shaft, a rotatable connector axially connected to said motor; a brush means removably connected axially to said connector and rotated thereby; a conduit partially located within said shaft and providing liquid communication from said container through said motor and said connector to said brush means; and control means associated with said handle for selectively allowing liquid from said container to pass to said brush means.
Claim 2
Independent Claim
126 words
An apparatus for manually treating a floor comprising in combination an elongated hollow shaft bent near one end at an obtuse angle to form a handle portion at said end for a user to hand operate said apparatus; a container removably secured to said shaft for storing cleaning liquid therein; an electric motor secured axially to the other end of said shaft, a rotatable connector axially connected to said motor; a brush means removably connected axially to said connector and rotated thereby; a conduit partially located within said shaft and providing liquid communication from said container through said motor and said connector to said brush means; and control means associated with said handle for selectively allowing liquid from said container to pass to said brush means.
Claim 3
Dependent Claim
37 words
The apparatus of claim 1, said brush means being configured so as to be capable of effectively contacting right angle corners of floors which abut against vertically extending walls, and said conduit extends into said brush means.
Claim 4
Dependent Claim
74 words
The apparatus of claim 2 wherein said control means comprises: valve means to restrict the flow of treating liquid from said container to said brush means; release means secured to said shaft; and a rod providing mechanical communication between said release means and said valve means so that when said user applies force to said release means said valve means opens to allow treating liquid to pass from said container to said brush means.
Claim 5
Dependent Claim
47 words
The apparatus of claim 3 wherein said release means is located in proximity to said handle means, and said control means is biasly constructed so that said valve means completely restricts the flow of said treating liquid when no external force is applied to said release means.
