  • Patent number: 9743747
    Abstract: A surface cleaning implement for use with an elongated handle is provided. The implement includes a largely rectangular and asymmetric body region with rounded outer edges, largely planar upper and lower surfaces, and upstanding contact material coextensively disposed thereon. The body region is a largely flattened structure having a first and second leading edge corner, the corners comprising where the leading edge of the body region transitions to the side edges. The first corner comprises a large, sweeping radius for cleaning curving and open surfaces. The second corner comprises a sharp corner having a small radius, chamfered, protuberant, or largely square corner wherein overly elongated and stiffened contact material extends therefrom for contacting surfaces within corners or within confined areas. The head region includes a back end having a handle receiving sheath and suitable support therefor, wherein an elongated handle is attached thereto for use away from the user's person.

  • Publication number: 20110000039
    Abstract: The present invention relates generally to a manually-operated household cleaning tool, and more particularly to household cleaning tool having optimum geometry for cleaning of bathroom, kitchen, floor, wall, ceiling, and other surfaces in the home. The shape of the tool head is designed to provide contiguous surface contact on a variety of concave basin surfaces while the angle and length of the handle attached thereto facilitates reach and leverage of the operator in potentially confined environments. The multiplicity of contact material and stiffness of said material further enhances the utility of the tool under any household condition.
