A specialized brushing device capable of tracking a user's routine living activities includes an enclosure body comprising a detachable handle with an on/off button, a brush head with a plurality of bristles, and a printed circuit board. The printed circuit board comprises at least one processor, wireless module, memory, graphic content displayed on a screen, haptic vibration module, motion module including at least one accelerometer, antenna, power module, notification indicator, and battery. The memory stores instructions executable by the processor to receive motion sensor detections, store sensor data, analyze the data to generate metadata including time of use, duration of use, and directional information, and generate a report indicating whether usage frequency is below that of a data model. An alert signal is sent to the notification indicator, which activates by light or vibration based on the report. The notification indicator comprises an indicator light, digital display, or haptic vibration module.

A power scrubber including a telescopic shaft, a power receptacle, a handle, a power head, a pivot coupling, a first scrubber head, a second scrubber head, and a drive. The power receptacle and the handle are each positioned adjacent the first end. The pivot coupling couples the power head to the second end and is operable to adjust an angle of the power head relative to the shaft axis. The drive is coupled to and driven by the power head and extends along a longitudinal axis. The drive includes a first connector selectively engaging the first scrubber head with a center of the first scrubber head aligned with the longitudinal axis and a second connector selectively engaging the second scrubber head with a center of the second scrubber head aligned with the longitudinal axis. The first connector is connected to the first scrubber by a bayonet coupling.

A multifunctional electric brush head is provided, which includes a control part, an execution part, a fixing component, and a work brush head; the control part rotates relativity to the execution part, the execution part rotates itself; thus, a wide clean range can be achieved. Different work brush heads can be replaced as needed to achieve a better clean result and work brush heads belonging to different fields can be replaced so as to adapt to a wide work scope. The electric brush head can be handheld to clean a dead angle, and it may be installed with a telescopic rod. It further includes a light to illuminate a to-be-cleaned place. The execution part and the telescopic rod are designed to cooperate with each other to achieve a fix and electrical connection effect, allowing the telescopic rod to also control an operation of the electric brush head.

The invention relates to the field of fish tank cleaning, in particular discloses a water exchanger. The water exchanger comprises a pressing balloon, a switch valve, a communicating pipe, a connecting pipe, a cleaning brush head and a water outlet joint. The cleaning brush head is equipped with multiple cleaning bristles and water inlet holes. Through the invention, the user can use one hand to press the pressing balloon to absorb water and rotate the switch valve to adjust the size of the water outlet channel and control the water flow rate. The user can use his spare hand to assist with water absorption or handle emergencies. Therefore, the use of the invention is more flexible and convenient.

A power tool for cleaning includes: a cleaning device including a working accessory for cleaning; a driving device, where the driving device includes a motor for driving the working accessory to rotate, and the motor includes a motor shaft rotating about a first straight line; an operation device for a user to operate so as to control the power tool; a power supply device for supplying power to the driving device; and a connecting device for connecting the driving device to the operation device. The operation device includes a main handle for the user to hold. The power supply device is disposed between the main handle and the driving device. The fatigue degree of the user is reduced when the user operates the power tool.
