CLEANING IMPLEMENT HAVING A VISUAL INDICATOR FOR DETERMINING DEBRIS REMOVAL EFFECTIVENESS AND END OF USEFUL LIFE

摘要

A visual indicator for the cleaning effectiveness and end of useful life of a cleaning implement, e.g., a fabric sweeper, for removing dust, dirt, pet hair and other debris present on a fabric surface. The implement comprises a housing and a pair of fabric-covered rollers. During a cleaning operation, the implement is swept over the surface to be cleaned. Debris is retained by the fabric on the rollers and transported to a collection chamber by the opposing roller. The fabric covering the rollers is a unidirectional fabric such as velour with a light color such as light blue. The light color provides an indication of cleaning effectiveness since the hair and debris loaded on the rollers contrasts with the light color and therefore can easily be quantified. The light color further aids in determining when the rollers have become too dirty such that the implement should be disposed and a new implement used.
