Abstract
A cleaning head for carpets, walls or upholstery, including a rigid, exterior, open-bottomed main body which defines the surface subjected to the cleaning process. Mounted within or adjacent to the main body portion coplanar with the bottom thereof is the fluid-applying device, which includes a slot at an acute angle to the plane of the bottom of the body located adjacent the plane of the bottom of the body, configured such that the fluid is applied in a thin sheet which flows out of the slot and into the upper portion of the surface to be cleaned and subsequently into the vacuum source for recovery.
Claims6
A cleaning head including a main body portion adapted to be used with a source of cleaning liquid, and a vacuum source for cleaning a floor, wall or upholstered surface;
- comprising:
- a lower surface contact area defined by a rectangular lip defined by the main body of the head, outlining the limits of operation of the tool as it is guided over the floor;
- liquid-applying means fixedly located within the confines of the lip, said liquid-applying means being configured such that the cleaning liquid is applied to the surface as a continuous film flowing over the lower surface, whereby the liquid is better controlled, there is no danger of overspray, and the surface is dried more quickly;
- means to interconnect the cleaning head and a source of cleaning liquid;
- and
- means to interconnect the cleaning head and a vacuum source.
A floor, wall or upholstery cleaning tool for use in conjunction with a source of cleaning liquid and a vacuum source comprising:
- means interconnecting the tool to the liquid source;
- exterior envelope means and interior supply means wherein the exterior envelope has a substantially uniplaner lower surface wherein the envelope means defines a substantially enclosed area of the floor when in contact therewith and is connected to the vacuum source and the supply means is interconnected with the source of cleaning liquid, said interior supply means provides an elongated bottom lip substantially uniplaner with the lower surface of the envelope means and is configured such that the liquid is selectively applied to the floor as a thin film which flows over the bottom lip.
A cleaning head adapted to be used with a source of cleaning liquid and a vacuum source for cleaning a floor, wall or upholstered surface, comprising:
- a lower surface contact area defined by a lip surrounding an opening through which a vacuum is applied for removing fluid and entrained soil;
- and
- a liquid supply means adjacent the lip, including an angled delivery slot, causing the liquid to flow in a sheet over the lip and into the vacuum.
