An apparatus for cleaning a surface includes a liquid delivery system for storing cleaning liquid and delivering the cleaning liquid to the surface to be cleaned, and an indicator system that is operably coupled with the liquid delivery system to indicate an operational status to the user operating the apparatus. The indicator system can include a light emitter that illuminates when an operational status is detected. The light emitter can illuminate the container storing cleaning liquid.

According to various embodiments, a robotic cleaner may include a battery; a driving device for moving the robotic cleaner; a cleaning device for allowing the robotic cleaner to perform cleaning work; and a processor configured to determine, as a zone that can be cleaned, a first zone in the entire space by considering the residual capacity of the battery and the location of a charging device, operate the driving device and cleaning device to perform cleaning of the first zone, and perform control such that the robotic cleaner moves to the location of the charging device. Other embodiments are possible.

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.

Methods, systems and apparatus for providing a notification of a wet floor are provided. A scrubbing robot for scrubbing a floor and having one or more liquid carrying components has a sensor coupled to it positioned for collecting data about an area of the floor proximate to the scrubbing robot and along a path over which the robot has travelled. An application is stored on the computer for determining that liquid is on the floor by analysing the data for a presence of a second set of parameters corresponding to or crossing (from above to below or from below to above) a set of threshold parameters that is indicative of the presence of liquid on the floor. A notification module coupled to the scrubbing robot issues at least one of a human detectable and a computer detectable notification in response to the application determining that liquid is on the floor.

The present application relates to a robot cleaner. The robot cleaner of the present application includes: a main body which forms an external shape; a water tank which stores water; a rotation mop which is in contact with a floor while rotating and moves the main body; a drive motor which rotates the rotation mop; a motion detection unit which measures a reference motion of the main body when the rotation mop rotates; and a controller which measures a slip rate based on an actual speed of the main body measured by the motion detection unit in the reference motion and an ideal speed of the main body estimated according to driving of the drive motor, and controls an amount of water supplied to the rotation mop.

Robotic devices are provided that can be operated in an autonomous mode. In various embodiments, the devices comprise lighting elements that are capable of displaying information to humans within a robotic environment. A variety of future and near-future actions are expressed through different operations and sequences of the lighting elements. The lighting elements further enable the device to express a current status.

A cleaning device comprises an upper cleaning solution tank comprising an outlet, a motorized chassis located beneath the solution tank and an electronics compartment defined at least partly by splash shields and a drip shield. The splash shields define a top and sides of the electronics compartment, and the drip shield defines a bottom side of the electronics compartment and includes at least one drip hole smaller than 2 mm in diameter. A wire opening in the splash shields includes a protective cover overlying the opening, the protective covering containing at least one passage facing in a direction opposite to the solution tank allowing a wire to pass through the passage, through the wire opening, and into the electronics compartment. Fluid lines extend from the outlet towards a bottom of the cleaning device and exterior to the electronics compartment. An enclosed electronics unit may also include wire openings and protective covers.

The present disclosure relates generally to an apparatus for cleaning or otherwise treating a floor or ground surface. Devices provided herein include various features to enhance the efficiency and efficacy of cleaning operations. Such devices includes, but are not limited to, bearing protector devices, cord and cable management devices, and ergonomic features useful with ride-on floor treating machines.

A surface cleaning apparatus is provided with a fluid delivery system for delivering a cleaning fluid to the surface to be cleaned. The fluid delivery system includes one or more fluid supply tanks for storing a supply of cleaning fluid, a fluid distributor for applying the cleaning fluid to the surface to be cleaned, and a fluid supply conduit for delivering the cleaning fluid from the fluid supply tank to the fluid distributor.

The present invention is a machine for treating a surface lying in an XY plane. The machine includes a body having a body plate, a cleaning plate, a cleaning pad, a drive assembly and an attachment assembly. The cleaning plate is located between the body plate and the XY plane. The drive assembly is connected to the cleaning plate to drive the cleaning plate with a cleaning vibration in an oscillating pattern parallel to the XY plane and producing a drive force for driving the machine over the XY-plane.
