Abstract
A vacuum cleaner protective guard is disclosed. My invention will save homeowners and business owners a lot of time and money because it eliminates the frequency of repainting, repairing, refinishing, retouching their baseboard, doors, and the bases of their furniture. A padded non-scuff material selected to be resistant to transfer to a finished surface of a structure through a frictional contact with the finished surface has a length corresponding to a front face and at least a portion of a side face of the suction head. Preferably the padded non-scuff material is felt.
Claims
exact text as granted — not AI-modifiedWhat is claimed is:
1 . A guard for a suction head of a vacuum cleaner, comprising:
an elongate strip of a padded material dimensioned to fit about at least a forward face and a forward portion of a lateral side of the suction head, the padded material selected from a non-scuff material that will not be transferred to a finished surface of a structure through frictional contact with the finished surface; and an adhesive layer disposed on an inner surface of the elongate strip; the adhesive layer selected to adhere the elongate strip to the suction head of the vacuum cleaner.
2 . The guard of claim 1 , further comprising:
a release layer covers the adhesive layer, wherein the release layer is removable from the adhesive layer.
3 . The guard of claim 1 , wherein the padded material is a felt fabric.
4 . The guard of claim 3 , wherein the felt fabric has a thickness of at least ⅛ inches.

6 . A method of preventing marring of a finished surface by contact with a suction head of a vacuum cleaner, comprising:
measuring a length of a padded non-scuff material that selected to be resistant to transfer to a finished surface of a structure through a frictional contact with the finished surface, the length corresponding to a front face and at least a portion of a side face of the suction head.
7 . The method of claim 6 , further comprising:
applying an adhesive layer on an inner face of the padded non-scuff material to the front face and the at least a portion of the side face of the suction head.
