Cleaning implement

Abstract

A cleaning implement is disclosed that provides multiple functions useful in cleaning windows and similar surfaces. There is a support head that has three sides, one being a cleaning liquid applicator side and two presenting an absorbent sheet. The liquid applicator side can apply a cleaning liquid to a surface to be cleaned and optionally can provide scrubbing to the surface. The sheet can perform rough drying followed by finish drying, and/or other functions. Replacement liquid applicator cartridges and replacement sheets, or stacks of sheets, are also disclosed.

1 . A cleaning implement for cleaning a surface, comprising:
 a handle;   a support head mounted on the handle for rotation, the support head having at least two sides that can be selectively positioned adjacent the surface;   an absorbent sheet removably covering at least one of the sides of the support head; and   a substrate forming one of said sides of said support head and being impregnated with a cleaning fluid and also being removably mountable to the support head, the substrate being suitable to deliver cleaning fluid to the surface.   
   
   
       2 . The cleaning implement of  claim 1 , wherein the support head has at least three sides that can be selectively positioned adjacent the surface. 
   
   
       3 . The cleaning implement of  claim 2 , wherein the absorbent sheet removably covers two of the sides of the support head. 
   
   
       4 . The cleaning implement of  claim 3 , wherein the absorbent sheet is part of a stack of such absorbent sheets, the stack being removably mounted to the support head along two of the sides such that a first sheet of the stack can be tom off from the stack after use to expose a second sheet of the stack. 
   
   
       5 . The cleaning implement of  claim 4 , wherein the first sheet of the stack has weakenings to facilitate tearing off the first sheet from the stack. 
   
   
       6 . The cleaning implement of  claim 4 , wherein at least one absorbent sheet of the stack comprises an outer absorbent layer linked to an inner barrier layer. 
   
   
       7 . The cleaning implement of  claim 1 , wherein the substrate comprises a fibrous material selected from the group consisting of polyester fiber, polypropylene fiber, cellulose acetate fiber, and bonded polyolefin fiber, and the substrate is impregnated with a cleaning fluid. 
   
   
       8 . The cleaning implement of  claim 1 , wherein the substrate can be removed from a remainder of the support head independently of removal of the absorbent sheet from that remainder of the support head. 
   
   
       9 . The cleaning implement of  claim 1 , further comprising a removable cover suitable to cover the substrate prior to use, and the support head is essentially triangular in cross section. 
   
   
       10 . The cleaning implement of  claim 1 , wherein the support head is capable of freely rotating along its longitudinal axis, but not for a complete 360 degrees of rotation. 
   
   
       11 . The cleaning implement of  claim 1 , wherein the absorbent sheet has at least one slot adjacent an end of the sheet that can hook onto a projection of the support head. 
   
   
       12 . The cleaning implement of  claim 1 , wherein a side of the support head is pivotably hinged to another side of the support head to facilitate mounting of the absorbent sheet. 
   
   
       13 . The cleaning implement of  claim 1 , wherein the substrate is mounted to a cartridge housing, and the cartridge housing is mounted to the support head. 
   
   
       14 . The cleaning implement of  claim 1 , wherein a cartridge housing houses a plurality of separated porous material that are impregnated with cleaning fluid. 
   
   
       15 . A refill cartridge for a cleaning implement, the cleaning implement being of a type suitable to clean a hard surface, the cartridge comprising:
 a cartridge housing; and   a porous substrate mounted to the housing, wherein the substrate is impregnated with a cleaning liquid and the substrate is suitable to deliver the cleaning fluid to the surface.   
   
   
       16 . The refill cartridge of  claim 15 , wherein the substrate comprises a fibrous material is selected from the group consisting of polyester fiber, polypropylene fiber, cellulose acetate fiber, and bonded polyolefin fiber, and the substrate is impregnated with a window cleaner. 
   
   
       17 . The refill cartridge of  claim 15 , wherein the substrate comprises an applicator portion and a reservoir portion. 
   
   
       18 . The refill cartridge of  claim 17 , wherein the reservoir portion is positioned in at least two separated wells, the two separated wells each holding a separate piece of a porous absorbent material impregnated with a cleaning liquid. 
   
   
       19 . The refill cartridge of  claim 17 , wherein the applicator portion is divided into segments. 
   
   
       20 . The refill cartridge of  claim 15 , wherein the substrate is sized so as to avoid gravity alone causing the cleaning liquid to drool out of the substrate.
