The invention pertains to a novel scraper assembly having a plurality of interchangeable scraper heads and handles and corresponding method for use. The scraper assembly further comprises a plurality of abrasive mechanisms, namely spring bristles, coiled springs, chainmail abraders and wire cloth abraders capable of effectively cleaning a surface without scoring or otherwise damaging the surface. The invention may be particularly useful for cleaning grills and ovens. Additionally, the invention may also be useful for shaping, adding texture to, stripping materials from or otherwise preparing a surface, including wood, metal or ceramic surfaces.

A cleaning pad for a robot cleaner includes a back piece, an absorbent sheet, and a water permeable web. The water permeable web has a web body which is of such a dimension as to form a downward draping unit to shield the absorbent sheet. The downward draping unit is embossed toward the back piece and along at least one line oriented in a lengthwise direction to form successive downward draping members each defining a height between a lowermost area thereof and a lower major surface of the back piece. The heights of the successive downward draping members are incrementally decreased from a rearmost one of the successive downward draping members to a frontmost one of the successive downward draping members.

A cleaning tool for use in abrading a surface for cleaning the surface includes a resiliently deformable backing member insert, and a chain mail abrader enclosure comprising a chain mail body having a plurality of interlinked rings. The chain mail abrader enclosure is configured to allow for insertion and removal of the resiliently deformable backing member insert. The resiliently deformable backing member is disposable within the chain mail abrader enclosure such that the backing member is positioned against the chain mail body to allow the chain mail body to conform to contours of the surface during abrading.

A grate cleaning device. The grate cleaning device is configured to wash grill grates. A pair of panels containing brush members are inserted into a housing. The panels are inserted so that the brush members on each panel face each other when they are inserted into the housing. The housing is liquid proof and configured to receive a liquid for cleaning therein. A grate device such as a grill grate can be inserted into the space between the pair of panels and slid in and out. The brush members act as an abrasive, cleaning debris from a grate such as a grill grate.

A twisted wire brush comprises a twisted wire core, and first and second lengths of spring coil. The twisted wire core comprises a first core wire intertwined with a second core wire. The first and second lengths of spring coil extend about the first core wire, and the second length of spring coil extends about the first length of spring coil. The first and second lengths of spring coil are pressed between the first core wire and the second core wire. In another embodiment, a method of making a twisted wire brush comprises providing a first and a second core wire, positioning a first length of spring coil to extend inside a second length of spring coil, and the first and second lengths of spring coil to extend about the first core wire, and twisting the first core wire and the second core wire about a core axis.
