A brush head including a central portion centered respective to a rotation axis, an attachment feature configured to secure the brush head for rotation about the rotation axis, and a plurality of lobes. The plurality of lobes extend radially outwardly from the central portion and the rotation axis. At least one lobe extends along a curvilinear path, the curvilinear path extending through the central portion. The lobe has varying widths along the curvilinear path, the varying widths being perpendicular to the curvilinear path.

A robotic vacuum cleaner equipped with a holonomic drive that can drive in a given direction, e.g., north (assigned orientation), and move in a different direction, while maintaining its assigned orientation or that of any desired portion of the robot, such as an intake, or any other portion of the robot that is needed for a particular maneuver. The robotic vacuum cleaner includes a removable, chargeable battery system including a battery pack having batteries and a battery management system extending across all the batteries of the battery pack. A housing, including a top cover, surrounds the battery pack and the battery management system (BMS). The top cover extends over the BMS and includes a circuit board therein. A connector is at least partially connected to the BMS and extends through the housing. The connector is configured to transmit signals between the battery management system and the robotic vacuum cleaner.

A robot cleaner and a control method thereof are disclosed. A robot cleaner, according to an embodiment of the present invention, comprises: a tilt sensor module; a distance sensor module; and a light amount sensor module. Each piece of sensed information is transmitted to a lifting information calculation module. The lifting information calculation module calculates information on whether the robot cleaner is lifted, by using each piece of the transmitted information. If it is calculated that the robot cleaner is lifted off a floor, a power module is stopped. In addition, if it is calculated that the robot cleaner is not lifted off the floor, the power module is driven. Accordingly, when a user lifts the robot cleaner, injuries to the user caused by operation of a drive module can be prevented.

A method of controlling a moving robot is provided. The method of controlling a moving robot includes the steps of: (a) performing a basic motion of the moving robot which moves on a rotating mop; (b) measuring the slip rate of the moving robot; and (c) controlling the travel of the moving robot.

A floor cleaning and polishing device has a polishing pad for a surface which is rotationally engaged upon a pad driver operatively engaged to a frame. A first set of wheels on the frame allow for tilted movement. A second set of wheels are positionable to a deployed position to elevate the first set of wheels from the surface and position the polishing pad parallel to the surface. The device may have a light projector engageable for light disinfecting. The polishing pads are configured with a plurality of polishing fabric sections separated by recesses therebetween.

The present disclosure provides an electric steam control method, a system thereof, and a steam cleaner. The method includes: obtaining current water temperature data of a hot water tank and a current power supply mode; determining whether a temperature corresponding to the current water temperature data is within a preset temperature range; and if the temperature is within the preset temperature range, entering a heat preservation mode, else detecting whether AC power is currently available; if the AC power is available, performing power supply using the AC power, else generating a water temperature alarm signal; and in the heat preservation mode, detecting whether a working state is currently in place; if the working state is in place, detecting whether the AC power is currently available and generating a steam ejection signal, and performing power supply by using the AC or DC power, else maintaining the heat preservation mode.

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.

An embodiment of the present disclosure provides a cleaning robot and a control method thereof. The cleaning robot includes: a chassis; a fluid applicator, carried on the chassis and configured to distribute a cleaning fluid on at least part of a cleaning width; a fluid storage apparatus, detachably connected to the chassis, wherein the fluid storage apparatus is in communication with the fluid applicator and configured to apply the cleaning fluid distributed by the fluid applicator to a floor; and a control unit, carried on the chassis and configured to control the fluid applicator to stop distributing the cleaning fluid in a case that a to-be-cleaned area of the floor reaches a preset value.

The invention refers to a battery pack (30) comprising a battery pack housing (32) and a battery cell (34) accommodated inside the battery housing (32) and a plurality of battery pack contacts (36) accessible from outside the battery housing (32) and electrically connected to the battery cell (34). The battery pack (30) is adapted to be electrically connected with its battery pack contacts (36) to respective electric appliance contacts (38) of an electronic appliance (2; 100) and to provide electric energy to the electronic appliance (2; 100) after connection thereto. It is suggested that the battery pack (30) comprises a card slot (40) in the battery pack housing (32) with a plurality of electric slot contacts (42) in electric contact with the battery pack contacts (36), and that the battery pack (30) comprises an electronics card (44) for releasable insertion into the card slot (40), the electronics card (44) comprising a wireless communication device (46).

A charging pile for sweeping robot including a main body, a storage component, a charging head, a charging cable, and a circuit board. The main body is provided with a first slot. The storage component, provided with a charging interface and an avoidance slot. The charging pile for sweeping robot includes a first mounting post movably connected to the main body. The charging cable is partly wound on the first mounting post, one end of which is detachably connected to the charging interface, and the other surrounds the first mounting post and penetrates through the avoidance slot and is fixedly connected to the charging head. The charging interface is electrically connected to the main body, so the charging cable can be wound on the first mounting post and contained in the first slot, prevented from being scattered on ground, and making the charging pile more beautiful when in use.
