Abstract: A cleaning device agitator system having an agitator and one or more cleaning members. The agitator has first and second ends, a longitudinal axis and one or more agitating devices. One or more friction surfaces may project from the spindle. The cleaning members are adjacent the agitator and adapted to move between a first position and a second position. In at least the second position, the cleaning members engage the agitator, such as by engaging the friction surfaces, to remove debris. Agitator and cleaning members may be incorporated into a cleaning head having an inlet nozzle and a chamber in which the agitator rotates, and there may be an activation mechanism using, for example, a resilient member to move the cleaning members. An overload protection device may be provided, and may adjust its sensitivity depending on whether the cleaning devices are in the first or second position.

Abstract: A vacuum cleaner and a method for controlling the motor power of a vacuum cleaner are disclosed. The vacuum cleaner comprises an electric motor and an electric power supply for providing electric power to the electric motor. Furthermore, a voltage measuring means for measuring a motor voltage over the electric motor and a current measuring means for measuring a motor current flowing through the electric motor are provided. The vacuum cleaner further comprises a control means for controlling, based on the measured voltage and the measured current, the electric power provided to the electric motor from the electric power supply towards a target motor power value.

Abstract: The present invention relates to a vacuum cleaner having a motor housing provided with an inlet and an outlet, a motor and suction fan unit, which is arranged in the motor housing and which is arranged to create a suction flow in through the inlet of the housing, through the motor and suction fan unit and out through the outlet of the motor housing. The vacuum cleaner further comprise holding means for holding the motor and suction fan unit at the motor housing and sealing means arranged to guide the suction flow from the inlet of the motor housing and into the motor and suction fan unit in a sealingly manner. The holding means is arranged to prevent propagation of vibrations originated in the motor and suction fan unit from the motor housing by the holding means responding resiliently to forces from the motor and suction fan unit, and the holding means carries the motor and suction fan unit at the housing.

Abstract: A vacuum cleaner nozzle having a rotatable member for picking up particles from a surface, and a cleaning arrangement for removing articles entangled to the rotatable member. The rotatable member rotates around a longitudinal axis. The cleaning arrangement has at least one support surface provided on a radially projecting member, and at least one cleaning member movable between a resting position in which the cleaning member is arranged at a distance from the support surface and a cleaning position in the vicinity of the rotatable member. In the cleaning position, the cleaning member cooperates with the support surface to remove entangled articles from the rotatable member during rotation of the rotatable member. The cleaning member includes a resilient sheet member capable of providing resilient contact with at least one segment of the at least one support surface in the cleaning position during rotation of the rotatable member.

Abstract: This invention relates to a dust indicator in a vacuum cleaner, which dust indicator (200) is arranged in a wall (102) at least partly defining a space of the vacuum cleaner that is set under negative pressure with respect to the outside of the wall during operation of the vacuum cleaner. The dust indicator comprises an air channel (211) having an air inlet (212) arranged at an outer side of the wall, and an air outlet (213) arranged at an inner side of the wall, such that an airflow is directed into the space during operation of the vacuum cleaner due to the negative pressure. The dust indicator further comprises a sensor (220) arranged for detecting dust by means of sending and/or receiving an electromagnetic signal which is transmitted through the space. The air channel is arranged such that the airflow prevents dust from sticking in an area of the path of the electromagnetic signal of the sensor.

Abstract: A vacuum cleaner having a base, an agitator, a motor, an agitator cleaner, first and second support assemblies, and an actuator. The agitator cleaner is movable to be spaced from the agitator or to engage the agitator to remove debris while the motor rotates the agitator. The support assemblies collectively support the base on a surface to be cleaned, and the first support assembly is movable between a raised position in which the agitator is proximal to the surface and a lowered position in which the agitator is spaced from the surface. The actuator is movable between an idle position and an operative position. The actuator has a first controller to move the agitator cleaner into the first position when the actuator is in the idle position, and a second controller to move the first support assembly to the lowered position when the actuator is in the operative position.

Abstract: Vacuum cleaners and methods of controlling a motor driven by a battery source in a vacuum cleaner. The vacuum cleaner has a motor, a battery source for providing power to the motor, a voltage measuring unit for measuring a voltage over the motor, and a current measuring unit for measuring a current flowing through the motor. Further, the vacuum cleaner comprises a control unit for controlling, based on the measured voltage and/or the measured current, the power provided to the motor from the battery source to attain a target motor power value during a specified time period running from start-up of the motor, and to gradually decrease the power provided to the motor after the time period ends.

Abstract: There is provided a dust detection system for a vacuum cleaner comprising a dust separation chamber (20) of cyclone type and having a separate dustbin (30) for collecting separated dust. The dust separation chamber is adapted to provide a generally cyclonic airflow for separating dust from a dust laden air stream, and is at a bottom (25) of the dust separation chamber connected via an outlet (22) to the dustbin. The dust detection system further comprises an emitter (41) positioned to emit an electromagnetic signal into the dust separation chamber during operation of the vacuum cleaner, and a receiver (42) positioned to receive the electromagnetic signal. The inventive concept is based on an understanding that when the dustbin becomes full, dust accumulates at the bottom of the dust separation chamber, i.e. stays rotating at the bottom, since it cannot enter the dustbin.

Abstract: An upright vacuum cleaner having a nozzle and a support movable between a projected state and a retracted state. The support, in its projected state, is adapted to support the vacuum cleaner in a self-standing position. The support is mounted to the nozzle and projects from the nozzle in its projected state.

Abstract: A mixer appliance having a base unit and a container unit. The base unit has a motor with a drive shaft. The container unit has a container and a rotor with a rotor shaft and a rotor element. A coupling arrangement connects the drive shaft and the rotor shaft when the container unit is connected to the base unit. A longitudinal axis extends through the drive shaft, coupling arrangement, and rotor shaft. The container unit has a bottom portion with a flexible diaphragm and a bearing member. The bearing member is supported by the flexible diaphragm, and the rotor shaft extends through the bearing member. The flexible diaphragm provides flexibility perpendicularly to the longitudinal axis, such that the bearing member is displaceable perpendicularly to the longitudinal axis to align the rotor shaft with the drive shaft along the longitudinal axis when the container unit is connected to the base unit.
