Replaceable cleaning pads

Abstract

A pad for cleaning a hard target surface. The pad has resiliently deformable protuberances for scrubbing grout and other irregularities in the target surface. The pad may be removably attached to a device for cleaning debris from a target surface.

1 . A pad for cleaning a hard surface, said pad comprising:
 A topsheet, said topsheet having a plurality of discrete protuberances extending outwardly from respective discrete proximal ends disposed on a continuous background to respective distal ends remote therefrom, said protuberances having a protuberance free height of about 2.5+/−0.3 mm, and an uncompressed height at 1.65 kpa of 0.65+/−0.2 mm; and   a backsheet joined to said topsheet in face to face relationship to form a laminate, said pad being removably attachable to a cleaning implement by releasable contact with the backsheet to the device.   
     
     
         2 . A pad according to  claim 1  wherein said protuberances have a protuberance free height of about 2.5+/−0.1 mm. 
     
     
         3 . A pad according to  claim 2  wherein said protuberances have an uncompressed height at 1.65 kpa of 0.65+/−0.1 mm. 
     
     
         4 . A pad according to  claim 1  wherein said protuberances have a first compressed height at 4.14 kpa of 0.65+/−0.1 mm. 
     
     
         5 . A pad according to  claim 1  wherein said attachment layer comprises an absorbent material. 
     
     
         6 . A pad according to  claim 5  wherein said attachment layer comprises a nonwoven material. 
     
     
         7 . A pad according to  claim 2  having a 24 mm peel face force of 100 g to 400 g. 
     
     
         8 . A pad according to  claim 7  having a 24 mm peel face force of 150 g to 350 g. 
     
     
         9 . A pad for cleaning a hard surface, said pad comprising:
 A pervious topsheet, said topsheet having a plurality of discrete protuberances extending outwardly from respective discrete proximal ends disposed on a continuous background to respective distal ends remote therefrom, said protuberances having a protuberance free height of about 2.5+/−0.3 mm, and a resiliency of 26 percent and within the range of 20 to 45 percent; and   an impervious backsheet, removably disposable on a cleaning implement; and   an core interposed between said impervious backsheet and said pervious topsheet, said topsheet, said core and said backsheet being joined in face to face relationship to form a laminate.   
     
     
         10 . A pad according to  claim 9  wherein said protuberances have an uncompressed height at 1.65 kpa of 0.65+/−0.2 mm. 
     
     
         11 . A pad according to  claim 10  wherein said protuberances have a first compressed height at 4.14 kpa of 0.65+/−0.1 mm. 
     
     
         12 . A pad according to  claim 10  having two opposed longitudinal edges, and two opposed end edges, said end edges being rounded.
