Apparatus for cleaning surfaces with automatic water supply and drain
First Claim
1. An apparatus for cleaning a surface comprising:
- a cleaning head for applying a liquid onto the surface and cleaning same;
a vacuum head for removing a mixture of used liquid, air and particles from the surface under a vacuum action;
means for separating the used liquid, air and particles from the mixture respectively and containing the separated particles;
a fan device for generating the vacuum action of the vacuum head;
a used liquid container for containing a volume of the used liquid separated from the mixture; and
a single liquid passage adapted to be connected at a first end to an external liquid supply and drain system, the single liquid passage having valve means at a second end thereof for establishing selective fluid communication of the single liquid passage with one of the cleaning head and the used liquid container, so that the liquid can be supplied to the cleaning head and the used liquid can be withdrawn from the used liquid container alternately through the single liquid passage.

Abstract
An apparatus for cleaning floor surfaces and the like includes a cleaning head and a vacuum head to apply water on the surface for a continuous cleaning and vacuum operation. A single water passage of the apparatus is adapted to be connected to an automatic central water supply and drain system to supply water to and withdraw used water from the apparatus alternately through the single water passage in a controlled manner. Fresh water and used water containers are provided for temporarily storing the fresh and used water respectively. A valve device is used to selectively direct the water flow from the single water passage to the fresh water container and water flow from the used water container to the single water passage. Dirt particles are separated from water and air, and are collected in a removable bin for periodic dumping. The apparatus of the invention assures a fully automatic and efficient wet cleaning and vacuuming operation.
