Abstract
A floor cleaning device for facilitating the removal of matter from a surface includes a receptacle with a resilient bottom member having substantially an arch shape with first and second opposed ends for contacting the surface. A side wall and a ramp are disposed along the perimeter of the bottom member. The ramp is oriented for having matter transported across it from the surface for deposit into the receptacle. Upon application of a force to the second end of the resilient bottom member, the first end has increased contact with the surface. In another embodiment of the invention, a resilient member has first and second opposed ends with a channel formed in the resilient member between the first and second end. A ramp on the first end is oriented for having matter transported across it from the surface for being deposited into the channel. Upon application of a force by a user to the second end of the resilient member, the first end has increased contact with the surface.
