The present invention relates to a retaining plate 1 for a vacuum cleaner filter bag, including a base plate 2 having a passage opening 3 formed therein and a closure device for closing the passage opening 3, where the closure device includes two closure parts 4, 5 arranged in a plane parallel to the passage opening 3, and where the closure parts 4, 5 are movable relative to each other in the plane, so that, by a closing movement in the plane, they are movable to a closure position at which they close the passage opening 3 by overlapping each a respective part of the passage opening 3.

Provided is a cleaning system including: a robot cleaner including a dust collecting device having a dirt outlet and an outlet door configured to open and close the dirt outlet; and a station including a collecting device configured to generate a suction force to suction dirt of the duct collecting device and a lever device provided with a lever configured to be fixable to the outlet door as the outlet door is being opened to allow the collecting device and the dust collecting device to communicate with each other, and a lever driving source configured to generate power for driving the lever.

The invention comprises a vacuum cleaner filter bag (1), comprising a bag wall (2) and a retaining plate (3), wherein the retaining plate (3) is connected to an at least partially cylindrical connection piece (4) which extends in a direction perpendicular to a passage opening (5) formed in the retaining plate (3), wherein the bag wall (2) is connected with the lateral surface of the connection piece (4) along the circumference thereof.

The present disclosure discloses a hand-push leaf suction machine with an automatic outage function for toppling which includes a housing provided with an air duct, a fan fixedly arranged in the housing, a dust collecting box, ground wheels arranged on two sides of the housing and supported on ground, auxiliary wheels arranged on two sides of the housing and supported on the ground, and a push handle arranged at a rear end of the housing.

A suction apparatus includes a suction apparatus housing, including a filter for cleaning a suction flow, wherein the suction apparatus housing has at least one filter fastening element for securing the filter to the suction apparatus housing, and including a filter cleaning device for mechanically cleaning the filter. The filter, the filter fastening element and the filter cleaning device are arranged within the suction apparatus housing. The filter cleaning device includes an actuation device and a hammer device. The actuation device and the hammer device interact such that the hammer device can be actuated by using the actuation device and, when actuated, the hammer device applies at least one pulse to the filter securing element.

A vacuum cleaner includes a suction inlet, a motor, and an impeller connected to the motor and operable to generate suction through the suction inlet upon operation of the motor. The vacuum cleaner further includes a power connector mounted to the vacuum cleaner and selectively connectable to a direct current (DC) power source and an alternating current (AC) power source. The power connector includes external terminals accessible from an exterior of the vacuum cleaner. The external terminals are configured for removable mechanical connection to each of the DC power source and an AC power supply cord such that the DC power source and the AC power supply cord are selectively and mechanically connectable to the same external power connector terminals.

A debris canister and filter assembly, which may be used in a vehicular vacuum cleaner, includes a debris canister having an inlet, an outlet, and a peripheral side wall. The peripheral side wall at least partially defines an interior space of the debris canister. A filter is disposed in the interior space of the debris canister, and includes filter media having a non-pleated portion and a pleated portion. The peripheral side wall forms a corner of the debris canister, and the filter media has a rounded-corner shaped to fit adjacent to the corner of the peripheral side wall.

A surface cleaning device for removing debris from a surface is described. The surface cleaning device comprises a cleaning head comprising a housing, wherein the housing defines an inlet and comprises brush chambers; at least one vent coupled to a top portion of the housing; and a sweeper assembly coupled to the housing and comprising brushes having bristles, wherein the cleaning head is configured create a suction with a surface by directing air flow into the housing through the inlet and out of the housing through the at least one vent.

A vacuum cleaner device is provided that comprises an automated disposable container device configured to place an unused disposable container for collecting vacuumed debris. In accordance with some embodiments, the vacuum cleaner device may be advantageous for collecting pet waste.
