AI Technical Summary

Benefits of technology

The invention is a floor cleaning apparatus with two suction units: one at the front and one at the rear. The apparatus allows for more powerful vacuum either by increasing the vacuum applied to one of the units or by increasing the flow rate of the suction. This is done without needing to change the power of the vacuum turbine.

Problems solved by technology

A drawback of this known device is that both suction units are always active in either travel direction of the cleaning apparatus but only one of the front and rear suction units is used to suck up the cleaning liquid applied to the floor via the brushing means.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The invention relates to a floor cleaning apparatus according to the preamble of claim 1 and to a method for cleaning a floor using the same according to the preamble of claim 27.[0003]2. Description of the Related Art[0004]An apparatus for cleaning a floor surface is known from U.S. Pat. No. 5,901,410 WINDMEISSER. This known cleaning apparatus is suitable for wet cleaning and comprises a front suction unit in front of the brushing means and a rear suction unit behind the brushing means. Fresh cleaning liquid is supplied to the brushing means from a first tank in either travel direction. The front suction unit and the rear suction unit both extend parallel to the brushing means and are both connected to a second tank. The cleaning liquid is sucked up by the rear suction unit when the cleaning apparatus is moved in forward travel direction and sucked up by the front suction unit when the cleaning apparatus is moved in a ...
