Abstract: The invention relates to a mobile sweeper comprising a housing, in which a sweeping roller driven by an electric motor is mounted for rotation, and a sweepings container for receiving sweepings, wherein there are mounted on the housing adjacent to the sweeping roller two front supporting wheels and at a distance from these at least one rear supporting wheel, each for rotation about an axis of rotation. In order to further develop the sweeper such that with the occurrence of surface unevennesses, there is no risk of the sweeping roller becoming blocked or of the sweeper tilting, it is proposed in accordance with the invention that the axis of rotation of a first front supporting wheel be arranged coaxially with the axis of rotation of the sweeping roller and, in relation to the main direction of movement of the sweeper, offset from the axis of rotation of the second front supporting wheel.

Abstract: A cyclone separator for a suction cleaning appliance is provided, including a separating container for separating cleaning liquid drawn in by suction, with an inlet through which suction air and cleaning liquid can be drawn by suction into an interior of the separating container, thereby forming a cyclone, a suction extraction line extending into the interior and connectable to a suction unit, with an outlet through which suction air can be drawn out of the interior, and a partition wall shielding the outlet from cleaning liquid, a space being provided between an inner wall of the separating container and the partition wall. The cyclone separator can include at least one transfer element arranged between the partition wall and the inner wall for transferring cleaning liquid from the partition wall to the inner wall, the transfer element bridging the space except for a maximum remaining space of 2 millimeters.

Abstract: A vacuum cleaner is provided, including a suction inlet, a dirt collection container, a filter device, a suction conduit, a suction unit, wherein the dirt collection container is in flow communication with the suction unit via the filter device and the suction conduit and wherein the filter device has a negative pressure applied to it by the suction unit, and including an external air valve device, wherein the filter device is capable of having external air applied thereto on the clean side thereof via the external air valve device and wherein for cleaning the filter device the external air valve device is capable of being brought from a closed valve position to an open valve position and back again from the open valve position to a closed valve position, characterized by a battery device for supplying energy to the external air valve device.

Abstract: A pump for a high-pressure cleaning device for delivering cleaning fluid is provided. The pump has at least one pump chamber, into which at least one piston plunges, and which is connected to a suction line via at least one inlet valve and to a pressure line via at least one outlet valve. A bypass line leads from the pressure line to the suction line. An overflow valve is arranged in the bypass line. The valve body of the overflow valve is connected to a control piston which is displaceably held in a control chamber with the interposition of a sealing element and moves the valve body into a closed or an open position as a function of the flow rate of the cleaning fluid in the pressure line. A sliding element is arranged in the control chamber and abuts sealingly on the wall of the control chamber.

Abstract: A floor treating apparatus is provided, including a support device, on the lower side of which there is held at least one floor treating tool, which is driven to rotate or oscillate, a handle device to guide the floor treating apparatus in at least one working position, which handle device is held on the support device so as to be pivotable about a pivot axis from the at least one working position into at least one parking position and vice versa, and a storage container for a treatment liquid. The floor treating apparatus includes a storage container receptacle, in which the storage container can be releasably positioned in the at least one working position of the handle device, and a securing device with at least one first securing member and at least one second securing member which can be moved relative thereto.

Abstract: The invention relates to a high-pressure cleaning appliance, comprising a heatable heat exchanger for heating up a liquid dispensable by the high-pressure cleaning appliance, a blower with a flow channel connected thereto for supplying combustion air to the heat exchanger, and a setting member for setting the amount of combustion air suppliable to the heat exchanger, the setting member having a channel constriction section which is positionable in the flow channel and movable relative thereto for changing the free cross-sectional area of the flow channel. In order to develop a generic high-pressure cleaning appliance further so that the amount of combustion air suppliable to the heat exchanger can be better adjusted, it is proposed that the channel constriction section be configured so as to be slidingly displaceable relative to the flow channel.

Abstract: A vacuum cleaner is provided with a dirt collection container and a suction head which can be placed on the dirt collection container, wherein the suction head has at least one suction unit which is in flow communication with the dirt collection container via a suction duct and a filter device and with at least one exhaust air opening via at least one exhaust air duct. To provide high suction capacity, a compact construction, and relatively little generation of noise during operation, the suction head has two suction units arranged next to one another, positioned in a vertical direction at the same level as the filter device and surrounded by a common exhaust air chamber, wherein the exhaust air chamber is in flow communication with exhaust air openings via a first and a second exhaust air duct and the filter device is arranged between the two exhaust air ducts.

Abstract: A vacuum appliance is provided including a dirt collection container for sucked-in vacuumed material, a suction unit for subjecting the dirt collection container to the action of negative pressure via a suction chamber, at least one filter element between the dirt collection container and the suction chamber in the flow direction of the air sucked in by the suction unit, at least one rechargeable battery for providing electrical energy for the suction unit, and at least one battery receptacle for holding the battery on the vacuum appliance. The vacuum appliance includes a filter cover transferrable from a closed position in which the filter element is covered, to a removal position in which the filter element is removable from and insertable into the vacuum appliance on the clean space side, and vice versa, and which filter cover includes the battery receptacle for the battery.

Abstract: A suction cleaning apparatus comprising a dirt collection container which has a suction inlet and is fluidly connected to at least one suction unit via at least one filter and at least one suction channel is provided. The suction cleaning apparatus further has at least one external air inlet which opens out into the suction channel downstream of the at least one filter and which is selectively closable and openable by means of a closing body. In order to reduce the installation space of the closing body required for proper filter cleaning, the suction channel has an external air inlet wall with at least one external air inlet. The closing body, sliding along the outer side of the external air inlet wall, is reciprocatingly movable between a closed position closing the at least one external air inlet and an open position opening the at least one external air inlet.

Abstract: A road sweeper is provided with a rotatingly drivable sweeping brush, a sweepings container, a suction blower in flow communication with the sweeping brush for taking in dust-containing air, and at least one filter for separating dust from the air drawn in, wherein the filter can be acted upon on the clean side with external air stored in a pressure container and subject to pressure, via at least one external air valve for cleaning. In order for the filter to be cleaned off with as small an amount of external air as possible, the pressure container can have a pressure container wall located opposite the clean side of the at least one filter, the at least one external air valve being arranged on the wall, wherein a section of a suction conduit extends between the pressure container wall and the clean side of the filter.
