To wipe out a large amount of fine dust, earth grains or the like on a floor with a light force, effectively peel off and wipe out a muddy contaminant or the like adhering to the floor, and further wipe out or otherwise even a relatively large volume of liquid on the floor via the adsorption thereof.

Two rectangular pieces of water absorptive nonwoven fabric 10 are jointed to each other with a hot melt adhesive along a whole periphery 12, and pulp 14 is laid between both pieces of the nonwoven fabric 10 in a substantially even state. Also, the nonwoven fabric 10 is formed, so as to substantially prevent the infiltration of the pulp 14 to surface, and have such a gap and thickness as not obstructing the absorption of water base liquid containing solid particles from treated surface to a liquid absorptive material. As a result, the pulp 14 absorbs water base liquid as well as water base liquid containing solid particles on the treated surface via the nonwoven fabric 10, and can arrest the solid particles contained in the solid particle containing liquid. At the same time, the pulp 14 can feed the water base liquid to the treated surface.
