Abstract

An entry mat for placement before an entry door to permit cleaning of shoe soles. The entry mat has a liquid reservoir with an open top, and a plurality of adjacent parallel generally cylindrical brushes mounted such that certain bristles thereof extend outwardly from the open top of the liquid reservoir for engagement of a shoe bottom and certain bristles thereof extend inwardly into the reservoir. At least one of the cylindrical brushes is rotatable. The mat has a liquid absorbing fabric material releasably retained in a taut configuration by a stretcher, a wiping mat, and a frame member having respective compartments within which the liquid reservoir, liquid absorbing fabric material and wiping mat are housed. Use of the entry mat is a three step process wherein shoe soles are first wiped on the wiping mat to remove larger sized debris. Next, the shoe soles are subjected to the brushes whereby the at least one rotating brush introduces liquid from the reservoir to the soles for cleansing. Finally, the shoe soles are repeatedly rubbed on the taut liquid absorbing fabric material for drying.
