FIELD OF THE INVENTION

This invention relates generally to mops, and more particularly to sponge mops.

BACKGROUND OF THE INVENTION

There is a need for an easier way to clean kitchen and bathroom edges and corners after using a broom, a regular mop, or a steamer mop to clean a floor surface. The dirt left by any mop, i.e. , steamer mops, flat mops, string mops, or mopping systems with pad refills, is too much to just leave on the floor. Consequently, it is often necessary to carefully bend over, or get on hands and knees with a wet paper towel, to wipe the dirt by hand that got pushed into the corners after using any of a variety of mops for floor cleaning.

Also, when using a typical mop, it is problematic when one needs to place the mop to allow it to dry. If the mop is stored upside down to prevent the wet mop from touching the floor, the mop is likely to fall over. If the wet mop is allowed to rest on the floor while it dries, an unsanitary condition is created where the damp mop can damage the floor and/or promote bacterial growth and mold. SUMMARY OF THE INVENTION

The sponge mop of the invention provides an easier way to clean kitchen and bathroom edges and corners after using a broom, a regular mop, or a steamer mop to clean a floor surface.

By using the sponge mop of the invention at the end of a broom handle, it is no longer necessary to carefully bend over, or get on hands and knees with a wet paper towel, to wipe the dirt by hand that got pushed into the corners after using any of a variety of mops for floor cleaning.

Also, when one needs to allow the sponge mop to dry, it can be placed along the handle of a broom, rather than a standard wet mop being stored upside down to prevent the wet mop from touching the floor, which could result in the mop falling over. Placing the sponge mop of the invention along the handle of the broom also avoids allowing the sponge mop to rest on the floor while it dries, which would create an unsanitary condition where a damp standard mop would damage the floor and/or promote bacterial growth and mold.

A general aspect of the invention is a handle-storable sponge mop with scrubber for use at a handle end of a broom handle. The handle-storable sponge mop includes: a sponge body having: a trailing surface, a leading surface, and a body surface extending between the trailing surface and the leading surface, a working channel extending longitudinally through the sponge body, the working channel having a first open end in the trailing surface, and a second open end in the leading surface, and a storage channel extending across through the sponge body, the storage channel having two open ends in the body surface, the working channel and the storage channel each configured to receive the handle end of a broom handle; a scrubber pad shaped so as to match the leading surface of the sponge body, the scrubber pad being attached to the leading surface of the sponge body; and a sponge head having a base surface and a sponge head surface, the base surface shaped so as to match the shape of the leading surface of the sponge body, the base surface of the sponge head being attached to the scrubber pad. In some embodiments, the sponge head is shaped as a truncated prism, the truncated prism having a base surface, a leading face, a longest rectangular side, a shortest rectangular side, and a pair of right-trapezoidal sides, the leading face and the longest rectangular side together forming a leading beveled cleaning edge.

In other embodiments, the storage channel extends between the pair of right- trapezoidal sides.

In other embodiments, the open channel extends perpendicularly between the pair of right-trapezoidal sides of the truncated prism.

In other embodiments, the truncated prism is one of: a triangular truncated prism, a square truncated prism, a rectangular truncated prism, a hexagonal truncated prism, an octagonal truncated prism.

In other embodiments the base surface is one of: a triangle, a square, a rectangle, a hexagon, an octagon, a circle.

In other embodiments, the truncated prism is a truncated right prism in which the longest rectangular side, the shortest rectangular side, and the pair of right-trapezoidal sides are perpendicular to the base surface.

In some embodiments, the working channel extends perpendicularly into the base face of the sponge body.

In some embodiments, the working channel and the storage channel are cylindrical channels.

In some embodiments, the working channel and the storage channel intersect.

In some embodiments, a central axis of the working channel and a central axis of the storage channel are in substantially perpendicular relationship.

In some embodiments, a central axis of the storage channel intersects with a central axis of the working channel. In some embodiments, a central axis of the storage channel extends perpendicularly with respect to a central axis of the sponge body.

In some embodiments, the sponge mop body and the sponge mop head are made entirely of absorbent material. In further embodiments, the absorbent material is selected from: polyurethane foam, foam rubber sponge material, microfiber textile, stranded cotton, stranded synthetic fiber, and stranded Rayon.

In some embodiments, the scrubber pad is made from heavy duty fiber material. In further embodiments, the scrubber pad is 1/4” thick.

In some embodiments, the scrubber pad is configured to as to resist penetration by the handle end of a broom handle when the broom handle is forced against the scrubber pad during use.
