Abstract

[Summary]

[Problem] To make it possible to clean even corners of a floor

[Solving Means] In a disk-shaped self-propelled floor cleaner 4 provided with a traveling part 6 and obstacle detecting means to travel by the traveling part 6 and, when the obstacle detecting means detects an obstacle, cleaning with a dust sheet 1 attached to the bottom part of the cleaner in a peelable manner while performing control of changing a traveling direction of the traveling part 6,

the dust sheet 1 has at least one protrusion 3 provided outside of an annular sheet 2 having the same dimensions as those of the circular bottom part of the cleaner 4.

[Selected Drawing] FIG. 1

Claims

1. A dust sheet formed of an annular sheet with a rear surface having a peelable removable structure, the dust sheet being affixed to a circular bottom part of a disk-shaped self-propelled floor cleaner to wipe a floor surface with movement of the self-propelled floor cleaner, wherein

the dust sheet has an outer perimeter provided with at least one protrusion extending therefrom and protruding sideward from the bottom part when affixed to the self-propelled floor cleaner, and an adhesive member attachable to an upper surface of the self-propelled floor cleaner is mounted on an upper surface of a tip part of the protrusion.

2. The dust sheet for a self-propelled floor cleaner according to claim 1, wherein

a plurality of the protrusions are provided at regular intervals.

3-10. -10. (canceled)

11. A dust sheet formed of an annular sheet with a rear surface having a peelable removable structure, the dust sheet being affixed to a circular bottom surface of a disk-shaped self-propelled floor cleaner to wipe a floor surface with movement of the self-propelled floor cleaner, wherein

when the dust sheet is affixed to the self-propelled floor cleaner, the dust sheet extends off an entire perimeter from an outer perimeter of the bottom part, and many incisions are provided to at least an extending-off part in a direction from a center toward the outer perimeter.
