A vacuum cleaner assembly basically includes a vacuum body, a first power source, an accessory, and a second power source. The first power source is configured to create flow through a suction path. The accessory is configured to be removably connected to the vacuum body. The second power source is configured to power the accessory. Each of the first and second power sources is configured to share power with the other of the first and second power sources.

A floor cleaning machine including an electrochemical cell having an anode, a cathode, an electrolyte, an electrochemical cell controller in at least one of unilateral and/or bilateral communication with at least one of the anode, the cathode, and the electrolyte, and wherein the electrochemical cell is associated with at least one of a recovery tank sub-assembly, a vacuum fan sub-assembly, a solution tank sub-assembly, a solution flow sub-assembly, a control console sub-assembly, at least one of a frame and wheel sub-assembly and a frame and transaxle sub-assembly, a scrub head sub-assembly, a scrub head lift sub-assembly, and a squeegee sub-assembly.

A navigation control system for an autonomous vehicle comprises a transmitter and an autonomous vehicle. The transmitter comprises an emitter for emitting at least one signal, a power source for powering the emitter, a device for capturing wireless energy to charge the power source, and a printed circuit board for converting the captured wireless energy to a form for charging the power source. The autonomous vehicle operates within a working area and comprises a receiver for detecting the at least one signal emitted by the emitter, and a processor for determining a relative location of the autonomous vehicle within the working area based on the signal emitted by the emitter.

A system and method for incident notification for an autonomous or a semi-autonomous cleaning device. The incident notification can be provided with or without videos using hyperlinks. Videos can be accessed directly on the cleaning device graphical user interface (GUI) on the incident notification dashboard. Based on the detected failure types, direct links to specific contextual help videos next to each incident notification can be provided to further troubleshoot the incident. The system simplifies the complexity of incident notification and improves the user experience by merging all monitoring on a single dashboard which can manage all simultaneous faults in a coherent manner.

A control method of a cleaning robot, where the cleaning robot includes a top part, a bottom part, and a vacuumizing assembly for air extraction, the bottom part of the cleaning robot is provided with at least two rows of driving wheels being respectively provided on both sides of the bottom part of the cleaning robot, and the cleaning robot includes a cleaning mode for cleaning the driving wheel; the method including: performing a cleaning mode of the cleaning robot; and after the cleaning robot performs the cleaning mode, turning off the vacuumizing assembly or maintaining the vacuumizing assembly in a turned off state, and starting and rotating at least one row of the driving wheels.

Provided is a cleaning system including: a robot cleaner including a dust collecting device having a dirt outlet and an outlet door configured to open and close the dirt outlet; and a station including a collecting device configured to generate a suction force to suction dirt of the duct collecting device and a lever device provided with a lever configured to be fixable to the outlet door as the outlet door is being opened to allow the collecting device and the dust collecting device to communicate with each other, and a lever driving source configured to generate power for driving the lever.

Disclosed are a robot cleaner. The robot cleaner includes: a cleaner body configured to move in an area and clean the area; and a sensor assembly provided in the cleaner body. The sensor assembly includes: a main sensor configured to be moveable between a sensing position where the main sensor protrudes out of the cleaner body and a settled position where the main sensor is inside the cleaner body; a sensor position changer configured to allow the main sensor to move between the sensing position and the settled position; and a stopper configured to restrict the sensor position changer from allowing the main sensor at the sensing position to move towards the settled position.

A system for cleaning a floor by means of at least one cleaning robot, which cleaning robot comprises control means for controlling the cleaning robot and communication means for sensing at least one event having increased soiling emergence of at least part of the floor, wherein the control means set the intensity of the use of the cleaning robot for cleaning at least part of the floor in accordance with the intensity of at least one event having increased soiling emergence. The system solves the technical problem of making a system and a method for cleaning a floor by means of a cleaning robot more flexible and enabling improved cleaning results. The system further relates to a method for cleaning a floor.

An air purification device includes a movement portion configured to move the air purification device to a target region; and a purification portion configured to purify air in the target region to improve air quality of the target region.

A vacuum cleaner includes an odor neutralizer and dust plume abatement system. The odor neutralizer and dust plume abatement system delivers a mist to a working air path of the vacuum cleaner, such as at or upstream of a working air treatment assembly defining a portion of the working air path.
