A vacuum cleaner to suction dust generated by a machine tool, wherein the vacuum cleaner is actuatable by an electric device in the shape of the machine tool or an energy storage module for the electric power supply of the machine tool, which has a drive motor to drive a tool holder on which a tool provided to process a workpiece is arranged or is arrangeable, wherein the vacuum cleaner has a vacuum housing with a dirt collection chamber to receive dirt separated from a suction flow and a suction unit to generate the suction flow, wherein a suction inlet is present on the vacuum housing to connect a suction hose to establish a current connection for the suction flow with the machine tool, wherein the vacuum cleaner has an external communication apparatus for a wireless control connection to a wireless communication interface of the electric device and to receive at least one control command to control, the vacuum cleaner via the control connection.

A controller for a vacuum cleaner includes a processor and a memory. The memory includes instructions that program the processor to operate a motor at a first power level, receive a temperature of a drive component associated with the motor from a temperature sensor, and compare the temperature of the drive component associated with the motor to a first threshold temperature. The processor operates the motor at a second power level lower than the first power level for a period of time when the temperature of the drive component associated with the motor is greater than or equal to the first temperature threshold, and continues operating the motor at the first power level when the temperature of the drive component associated with the motor is less than the first temperature threshold.

An apparatus and method for monitoring the productivity of a portable machine are provided. The method includes receiving motion data for at least one component of the portable machine from a multi-axis accelerometer, receiving position data for the at least one component from a process parameter sensor communicatively coupled to the at least one component, and determining, based on the received motion data and the received position data that the at least one component is oriented in a predetermined position for productive operation. The method also includes determining an area of productive operation using at least one physical dimension of the at least one component and the received motion data when the at least one component is oriented in the predetermined position for productive operation and incrementing a total area counter based on the determination.

A cleaning device is provided with at least removable lamp console. When the lamp console is attached, the device can be used as a floor or desk lamp to illuminate a room and/or a table-top. The lamp console is removable to enable the device and/or lamp console to be used as a cleaner to clean a floor or other cleaning surface. Each lamp console is provided with a coupling mechanism that enables selective and electro-mechanical communication with a coupling mechanism of a cleaning device. This coupling enables interchangeability of various lamp consoles. Embodiments provide for a lamp console that acts as a handle-extension. Further embodiments provide for a second illumination display disposed on a portion of the cleaning device.

A motor cover includes a lattice structure defining a plurality of vent openings that provide ventilation of the motor cover. Each vent opening of the plurality of vent openings is defined by a first cross member, a second cross member, a first side member, and a second side member of the lattice structure. The second cross member is spaced vertically below the first cross member and the first side member is spaced horizontally forward from the second side member. Each of the first and second side members extend from the first cross member to the second cross member. The second cross member extends further outward from a central vertical axis of the motor cover than the first cross member, and the first side member extends further outward from the central longitudinal axis than the second side member.

The present invention is directed to a vacuum including a dust extraction system. The system includes a filter assembly, an airflow generation assembly, and valve assembly. The airflow generation assembly is configured to draw contaminated air toward the filter assembly and exhaust filtered air as a discharge stream. The filter assembly is configured to remove contaminants from the contaminated airflow by capturing particulate material suspended within the airflow. The valve assembly is configured to selectively direct filtered airflow into the filter assembly such that the filtered air stream cleans the filter.

A cleaning device and methods for cleaning are provided. In one embodiment, the cleaning device includes a head assembly, a body assembly, and a handle assembly. The cleaning device also includes components that enable the cleaning device to operate in dry cleaning modes and wet cleaning modes. Dry cleaning modes can employ a vacuum assembly, including a motor, tubing, and a fluid recovery tank in order to draw in debris and waste into a fluid recovery tank. Wet cleaning modes can further employ a fluid supply tank, a pump, and tubing in order to supply fluid to a brushroll to aid in a cleaning process.

A vacuum cleaner has a portable cleaning unit that is removably mounted to the surface cleaning head. The vacuum cleaner is operable in a floor cleaning configuration in which the portable cleaning unit is mounted to the surface cleaning head and is part of the air flow path through the vacuum cleaner. The portable cleaning unit is also useable in a portable cleaning configuration in which the portable cleaning unit is removed from the surface cleaning head and the suction motor is powered by an energy storage member.

A dust extractor (1) includes a motor (30) and a blower fan (40), which is disposed downward of the motor and is connected to the motor. The dust extractor further includes a flexible (pliable) support member (50; 500), which has a lower-end portion (52) connected to the motor and suspends the motor.

A vacuum cleaner includes a housing, a debris chamber defined within the housing, and a motor assembly connected to the housing and operable to generate airflow through the debris chamber. The motor assembly includes a motor, an impeller, an impeller housing, and a controller. The impeller is connected to the motor and operable to generate airflow upon operation of the motor. The impeller housing is constructed of an electrically-conductive material. The impeller is positioned within the impeller housing. The controller includes a circuit board assembly. The circuit board assembly including a common circuit, and the impeller housing is electrically connected to the common circuit.
