Claim:
A cleaning sheet having a cleaning surface comprising a cleaning area for cleaning a piled surface and a low-friction area which adjoins said cleaning area, wherein said cleaning area has a first sheet as a scraping part and second sheet as a dust-holding part, wherein the first and second sheets extend in the same direction; said first sheet is an air-laid nonwoven fabric comprising at least one thermoplastic resin selected from the group consisting of a polyolefin, polyamide, polyester and a fluororesin, and the air-laid surface comprises numerous fibers having a fineness of 23 to 200 dtex; said second sheet comprises spun-laced, air-through or spun-bonded nonwoven fabric; said scraping part of the first sheet having on the surface thereof numerous fibers that edges into the pile of a piled surface and scrapes fibrous dust present in said pile, said fibers mainly comprising fibers constituting the air-laid nonwoven fabric, and said dust-holding part of the second sheet holds the scraped fibrous dust by having the fibrous dust physically entangled therewith; wherein said cleaning area having a coefficient of static friction of 0.1 to 4.0 against wool press felt (JIS L3201 R33W), wherein said cleaning area contains the air-laid nonwoven fabric, and said low-friction area comprises a film or a nonwoven fabric, and wherein said low-friction area has a coefficient of static friction of 0.01 to 1.0 against wool press felt (JIS L3201 R33W).
