CLEANING DEVICE
First Claim
1. An assembly for cleaning surfaces comprising:
- a chassis having a forward end and a rear end;
a forward roller assembly mounted in the chassis at the forward end;
a rear roller assembly mounted in the chassis at the rear end;
a flexible cleaning web having a first cleaning surface, an opposed second cleaning surface, a leading end and a trailing end;
wherein the leading end of the cleaning web is attached to one of the forward and the rear roller assemblies and the trailing end of the cleaning web is attached to the other of the forward and the rear roller assemblies;
an advancement mechanism for driving at least the roller assembly to which the leading end of the cleaning web is attached;
whereby operation of said advancement mechanism transfers the cleaning web between the forward roller assembly and the rear roller assembly by wrapping the cleaning web around the one of the forward and the rear roller assemblies to which the leading end of the cleaning web is attached and simultaneously unwrapping the cleaning web from the other of the front and the rear roller assemblies to which the trailing end of the cleaning web is attached;
whereby the cleaning web is adapted to be wrapped around the one of the forward and the rear roller assemblies to which the leading end of the cleaning web is attached so that the first cleaning surface faces outwardly from and the second cleaning surface faces inwardly toward said roller assembly; and
further whereby the cleaning web is adapted to be wrapped around the other of the forward and the rear roller assemblies to which the trailing end of the cleaning web is attached so that the first cleaning surface faces inwardly toward and the second cleaning surface faces outwardly from said roller assembly.

Abstract
A cleaning device includes a chassis with a plurality of roller assemblies disposed therein, and a cleaning web having a first and second cleaning surface. The cleaning web extends between the roller assemblies such that the first cleaning surface of the cleaning web faces outwardly from one of the roller assemblies and towards a surface to be cleaned and the second cleaning surface faces outwardly from another roller assembly and towards the surface to be cleaned permitting both sides of the cleaning web to be used efficiently during a cleaning operation. The cleaning device further includes an advancement mechanism for advancing the cleaning web between the roller assemblies. A handle assembly with control elements is provided for guiding and controlling operation of the cleaning device. The cleaning device further includes a fluid delivery assembly for storing and delivering fluids to the cleaning web.
