A robotic device comprising: an energy storage device; and a controller configured to determine whether a quantity of energy stored in the energy storage device is below a predetermined energy level, wherein: the robotic device is configured to perform a cleaning task if the determined quantity of energy is not below the predetermined energy level; if the determined quantity of energy is below the predetermined energy level: the controller is configured to estimate a likelihood of the robotic device being capable of locating a recharging base station; and in dependence on the estimated likelihood, the robotic device is configured to seek the recharging base station or perform the cleaning task.

The invention relates to a cleaning system, comprising a cleaning cart and an external accessory device, wherein the cleaning cart comprises a frame having rollers for moving on a ground surface, at least one receptacle for receiving and/or carrying cleaning utensils, and an interaction device having a hand-actuatable interaction element, wherein the accessory device is portably configured and a user application program for processing cleaning-related information is executably stored on the accessory device and/or operable via the accessory device, wherein the interaction device and the accessory device are coupleable with one another via a communication connection, and wherein, depending on an actuation of the interaction element by the user, input information for operation of the user application program is transmittable from the interaction device to the accessory device and is processable by the accessory device. The invention further relates to a method for operating a cleaning system.

An electrical device, in particular in the form of a suction device (10) or a machine tool, with a housing (20) in which at least one electrical load, in particular an electric drive motor (11D), is arranged, wherein the electrical device has a power supply unit (80) with an energy storage receptacle (81), for the electrical power supply of the electrical load, in particular the drive motor (11D), in the interior of which at least two device interfaces (90A, 90B) for the detachable connection of a respective energy storage interface (190A, 190B) of an electrical energy storage (170A, 170B), in particular a battery pack, are arranged. The device interfaces (90A, 90B) are arranged on opposite side walls (83, 84) of the energy storage receptacle (81), so that the energy storages (170A, 170B) can be arranged on the device interfaces (90A, 90B) with mutually facing bottom walls (175).

The present disclosure relates to the field of cleaning robot technology, and in particular to a cleaning robot system. The cleaning robot system includes a base station and a cleaning robot. The base station is independent to the cleaning robot of the cleaning robot system. The base station includes a base station body and a mop member cleaning device arranged on the base station body. The mop member cleaning device is configured to clean a mop member of the cleaning robot. Based on the base station, the cleaning robot system is capable of automatically cleaning the mop member with no need for users to change or clean the mop member frequently, which is helpful to free consumers from house cleaning, thus relieving the burden on the consumers, and also helpful to clean the mop member in time so as to ensure a better effect in next cleaning.

An autonomous floor cleaner can include a housing, a drive system for autonomously moving the housing over the surface to be cleaned, and a controller for controlling the operation of the autonomous floor cleaner. The drive system can include at least one drive wheel for driving the housing across a surface to be cleaned. The drive wheel can be selectively moved from an engaged or in-use position to a disengaged or maintenance position. In the disengaged or maintenance position, the wheel is disengaged from the autonomously moveable housing such that it can be pivoted, extended, removed, or otherwise moved farther away from the autonomously moveable housing.

A portable cleaner has a recovery tank, including a container for receiving and storing recovered liquid and/or dirt and an openable tank lid for covering the container. The container and the tank lid are removable from the cleaner as a unit. The portable cleaner also has a main housing configured to removably support the recovery tank in a vertical orientation in which the tank lid at least partially defines a top side of the portable cleaner. In addition, a tank latch is provided in the tank lid, the tank latch configured to selectively secure and release the tank lid to the main housing when the recovery tank is supported by the main housing.

The present disclosure relates to a robotic cleaner. The robotic cleaner may be configured such that an imaginary plane passing mop contact portions having a small area passes through the center of gravity of the robotic cleaner, thereby travelling while the mops effectively scrub a floor surface.

A wet surface cleaner operable in an upright cleaning mode, an auxiliary cleaning mode, and a lift-off cleaning mode. The surface cleaner has a canister assembly that is coupled to a body in the upright cleaning mode and removed from the body in the auxiliary cleaning mode and the lift-off cleaning mode.

In some examples, a moisture-proof mat is provided for an intelligent cleaning apparatus or an intelligent cleaning system. The intelligent cleaning apparatus is provided with a wet cleaning pad. The intelligent cleaning apparatus can be charged by a charging station. The moisture-proof mat may include an installation unit, configured to install the moisture-proof mat to the charging station. At least a portion of the moisture-proof mat is configured to be located under the wet cleaning pad (4) when the intelligent cleaning apparatus is charged by the charging station. When the intelligent cleaning apparatus is charged by the charging station, at least a portion of the moisture-proof mat is positioned under the intelligent cleaning apparatus.

The present invention relates to systems and methods for cleaning materials, such as flooring and upholstery. In some cases, the systems and methods use an electrolytic cell to electrolyze a solution comprising sodium carbonate, sodium bicarbonate, sodium acetate, sodium percarbonate, potassium carbonate, potassium bicarbonate, and/or any other suitable chemical to generate electrolyzed alkaline water and/or electrolyzed oxidizing water. In some cases, the cell comprises a recirculation loop that recirculates anolyte through an anode compartment of the cell. In some cases, the cell further comprises a senor and a processor, where the processor is configured to automatically change an operation of the cell, based on a reading from the sensor. In some cases, a fluid flows past a magnet before entering the cell. In some additional cases, fluid from the cell is conditioned by being split into multiple conduits that run in proximity to each other. Additional implementations are described.
