## Abstract

The present invention is a device for cleaning surfaces comprising; a housing having a handle on one end and a cleaning head on the other end the cleaning head having an upper surface, a lower surface, a perimeter edge and a magnetic means. The magnetic means is removably attached to the cleaning head and provides a magnetic field to its lower surface. There is at least one attachment means provided on the upper surface or the perimeter for securing a cleaning sheet over the lower surface of the cleaning head.

## Claims

### Claim 1

A device for cleaning a surface of an item comprising:
a housing having a handle on one end, a cleaning head on the other end, wherein said cleaning head has an upper surface, a lower surface and a perimeter edge, a magnet for supplying a magnetic field affixed to a means for regulating said magnetic field secured within said cleaning head, wherein said means for regulating said magnetic field are two or more slots provided at said perimeter edge of said cleaning head able to receive said magnet, said two or more slots being positioned parallel to and at incrementally greater distances from said surface of said item to be cleaned; and
at least one attachment means provided on said upper surface or said perimeter edge for securing a cleaning sheet over said lower surface of said cleaning head.

### Claim 2 (depends on 1)

A device according to claim 1, wherein said magnet is at least one rigid magnet or flexible magnetic sheet.

### Claim 3 (depends on 1)

A device according to claim 1, wherein said housing further comprises a flexible means between said handle and said cleaning head that allows said cleaning head to pivot about the handle.

### Claim 4 (depends on 3)

A device according to claim 3, wherein said flexible means is comprised of a universal joint and a rotational joint.

### Claim 5 (depends on 1)

A device according to claim 1, wherein said attachment means functions by way of direct pressure.

### Claim 6 (depends on 1)

A device according to claim 1, wherein said attachment means is a clamp.

### Claim 7 (depends on 6)

A device according to claim 6, wherein said clamp is activated by a spring or a magnet.

### Claim 8 (depends on 6)

A device according to claim 6, wherein said clamp is a snap.

### Claim 9 (depends on 1)

A device according to claim 1, wherein said attachment means functions by way of frictional pressure.

### Claim 10 (depends on 1)

A device according to claim 1, wherein said attachment means is a hook and loop fastener, at least one serrated strip or at least one pressure grip.
