Definitions

• the invention initially relates to a self-propelled or traversing sweeper with a sweeping brush and an associated protective collecting space.
• Sweepers of the type in question are known.
• DE 44 14683 AI a sweeper is described and shown, which is provided with a device for picking up dust, dirt or the like from a surface to be cleaned with brushes and a receiving chamber for dirt.
• This sweeper can be interconnected with a suction device for emptying the receiving chamber.
• the sweeping device known from the aforementioned patent application is designed as a hand-held or stick-guided device having an electric motor for driving the sweeping brushes.
• self-propelled sweeping devices such as sweeping robots are known which autonomously work larger areas, in particular hard areas, by means of sweeping brushes and store the collected dirt in a receptacle.
• the design of the sweeping device according to the invention is conceivable both with autonomously operating sweeping devices, such as sweeping robots, and with hand-held or stick-guided sweeping devices.
• the individual assemblies of the sweeping device - sweeping device, liquid application device and Eutfeuchtung device - preferably work simultaneously.
• a solution is also conceivable in which individual assemblies can be activated as required.
• the specified inventive solution also results in a novel method for cleaning hard floors, in particular in the household sector, with sweeping first in one operation, then applying liquid to the hard floor and finally taking up the liquid film mixed with dirt particles.
• hard floors are cleaned without long set-up times, without physical contact with dirt or cleaning fluid, as is the case, for example, with conventional wet wiping and cleaning, and with only little physical exertion.
• sweeping and damp cleaning of overfloor surfaces and, for example, vertical surfaces such as wall tiles, shower cubicles or the like is also possible by means of the sweeping device according to the invention.
• a cleaning roller is arranged in front of the dehumidifying device, by means of which the floor moistened by the liquid application device is processed mechanically. So even stubborn dirt on the hard floor can be removed in one operation.
• cleaning roller which is preferably driven by an electric motor, leads to very good results even without multiple forward and backward movement of the sweeper over the area to be cleaned.
• the cleaning roller is preferably covered with a cleaning cloth.
• the cleaning roller can also be a bristle roller.
• the cleaning roller rotates at a higher relative speed with respect to the floor than the travel speed of the sweeper. For example, with a cleaning roller diameter of 40-60 mm, there is a rotation speed of the cleaning roller of more than 500 rpm, for example about 1000 rpm.
