20110232024 | Arrangement of a Motor Protection Filter in a Vacuum Cleaner - A vacuum cleaner has a lid that selectively opens or closes a filter bag compartment. A secondary motor protection filter is removably mounted in the lid by a frame of an elastic material that simultaneously seals the secondary filter element to the lid and seals the lid onto the bag compartment. An air passage flows between the secondary filter and the lid through a duct to the suction motor compartment. A perimeter groove in the lid receives a spline of the elastic frame of the filter element in a removable manner, while the opposite surface of the frame forms the seal surface relative to a housing rim around the bag compartment. | 09-29-2011 |
20110232687 | Vacuum Cleaner With Motor Speed Indicator - A vacuum cleaner includes a variable speed suction motor and an illuminatable motor speed indicator having plural lights arranged in a circular pattern or annular ring pattern, for example around a motor speed control switch. A control unit includes an indicator controller and a motor controller that respectively control the illuminatable indicator and the motor, based on inputs from the motor speed control switch and optionally at least one sensor that senses operating conditions of the vacuum cleaner. The lights are successively activated and deactivated to create a visible light spot that appears to rotate around the circular or annular ring pattern at a light rotation rate related to and indicative of the motor rotation speed. Thereby the indicator allows the vacuum suction power to be visually monitored. | 09-29-2011 |

20150313427 | Floor care appliance - In a vacuum cleaner it is provided that a brush set can be connected via a pivotable connecting element in the form of a connecting piece for an attachable filter housing to a handle in the form of a hand grip. Here the brush set has an electric motor for a suction fan and for the drive of the brush roller. The pivotable connecting element of the brush set has an external connector plug for an electrical connection to an appliance coupling of a power line connection lead for connection to a power supply, for example, for connection to a wall socket and the like. As a result, the brush set with the integrated motor and a switch for operating control forms a functional electrical unit. | 11-05-2015 |
20150313428 | Floor care appliance - A brush vacuum cleaner having a brush set facing the floor with a driven brush roller, wherein the brush set can be connected via a pivotable connecting element in the form of a connecting piece for a filter housing attachable to a handle having a hand grip. The brush set accommodates an electric motor for a suction fan and for the drive of the brush roller. An electrical switch is provided for switching the electric motor on and off which is disposed on the side wall as a lateral flank of the brush set in the form of a foot operated switch. The switch with its external control surface projects outwards with respect to the side wall in the switched-off position whereas in the switched-on position the control surface ends with neighbouring or adjacent surface sections of the side wall without overhang. | 11-05-2015 |
20150313429 | Floor care appliance - A brush vacuum cleaner having a brush set for receiving a driven brush roller, wherein at least one electric motor for a suction fan and for the drive of the brush roller is disposed in the brush set and wherein at least three air guiding channels are formed in a pivotable connecting element between the brush set and a filter housing. A supply of the dirt-laden suction air from the brush set to the filter housing takes place through the first air guiding channel, the filtered air is returned to the brush set through the second air guiding channel and through the third air guiding channel exhaust gas of the suction fan is returned to the filter housing to an air outlet. | 11-05-2015 |
20150313430 | Unknown - A floor care appliance having a height-adjustable brush set. A pushbutton of the brush set is actuatable for height adjustment via a manual suction tube of the floor care appliance. The pushbutton has a receptacle for receiving an edge region of a manual suction tube and/or for foot actuation. | 11-05-2015 |
