A cleaning tool is used for cleaning hard to reach surface areas with a cloth, pad or the like. The tool has a head in the form of a shallow circular, cup of a somewhat flexible material mounted pivotally on a long handle. The peripheral rim of the cup is equipped with a set of teeth that grip the cloth and hold it in place as it is wiped over the surface to be cleaned. Within the cup is a short cylindrical member, also provided with a set of cloth-gripping teeth on its outer, annular face.

Why it's free to use
- Filed November 18, 1994. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended November 18, 2014.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by November 18, 2016.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
