What is claimed is: 1. 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). 2. The cleaning sheet according to claim 1, wherein the area ratio of said low-friction area to said cleaning surface is 10 to 60%. 3. The cleaning sheet according to claim 1, wherein said low-friction area is disposed on one side of said cleaning surface across the cleaning direction of said cleaning surface. 4. The cleaning sheet according to claim 3, wherein said low-friction area is disposed on both sides of said cleaning surface across the cleaning direction of said cleaning surface. 5. The cleaning sheet according to claim 1, wherein said first sheet is disposed on said second sheet.
