Abstract
The invention relates to a cleaning apparatus comprising a cleaning device placed on a first side of the apparatus to perform a cleaning apparatus perpendicular to the general direction of advance of the apparatus. The apparatus could also include a second lateral cleaning device located on a side opposite the first side of the apparatus, to perform, simultaneously with the first cleaning device, the desired cleaning operation perpendicular to the general direction of advance of the apparatus, so as to be able to complete the entire cleaning operation without it being necessary for the apparatus to proceed along a wall.

10. A method of cleaning a particular area, such as a room surrounded by a plurality of boundary walls consisting of the steps of:
-
a) providing a cleaning apparatus having a body provided with supporting wheels with first and second cleaning devices, each having a cleaning-nozzle and a hose, said body capable of movement in a first direction, and said cleaning devices and said hoses capable of extending from said body in a direction perpendicular to said first direction, and said hoses capable of being withdrawn into said body; b) said cleaning apparatus entering a particular area to be cleaned provided with at least two boundary walls provided opposite one another; c) moving said cleaning apparatus to approximately the middle of one of the boundary walls, and in close proximity therewith; d) extending said cleaning devices in a direction perpendicular to said first direction to clean a strip of floor; e) rewinding said cleaning device into said body; f) moving said cleaning apparatus in said first direction a distance less than the length of said cleaning nozzles; g) repeating steps d), e) and f), until said cleaning apparatus reaches the opposed boundary wall; and h) having said cleaning apparatus exit the particular area to be cleaned. - View Dependent Claims (11, 12)
