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.

An autonomous coverage robot includes a chassis having forward and rearward portions and a drive system carried by the chassis. The forward portion of the chassis defines a substantially rectangular shape. The robot includes a cleaning assembly mounted on the forward portion of the chassis and a bin disposed adjacent the cleaning assembly and configured to receive debris agitated by the cleaning assembly. A bin cover is pivotally attached to a lower portion of the chassis and configured to rotate between a first, closed position providing closure of an opening defined by the bin and a second, open position providing access to the bin opening. The robot includes a body attached to the chassis and a handle disposed on an upper portion of the body. A bin cover release is actuatable from substantially near the handle.

A floor cleaning apparatus comprising a housing, a motorized agitation system, and at least one removable pad alignment jig. The motorized agitation system comprising a plurality of rotatable pad holders provided on the housing, a plurality of cleaning pads, and at least one drive motor operably coupled with the plurality of rotatable pad holders. One of plurality of cleaning pads being provided on each of the plurality of rotatable pad holders for rotation thereof.

A washing apparatus washes a cleaner having a mop unit formed at a lower portion thereof. The washing apparatus includes a tray configured to form a space to receive the cleaner and washing water. A washing unit is disposed at a lower portion of the inside of the tray in contact with the mop unit. The washing unit includes a first spinning mop protrusion line configured to protrude upwardly, an upper end of the first spinning mop protrusion line being inclined downwardly in a first direction.

The forward portion of the chassis defines a substantially rectangular shape. The robot includes a cleaning assembly mounted on the forward portion of the chassis and a bin disposed adjacent the cleaning assembly and configured to receive debris agitated by the cleaning assembly. A bin cover is pivotally attached to a lower portion of the chassis and configured to rotate between a first, closed position providing closure of an opening defined by the bin and a second, open position providing access to the bin opening. The robot includes a body attached to the chassis and a handle disposed on an upper portion of the body. A bin cover release is actuatable from substantially near the handle.

A motorized floor mop that can deliver liquid to a surface to be cleaned is provided with a handle, a base, a fluid delivery system, a motorized agitation system and a multi-axis swivel joint coupling the handle with the base for movement of the handle. A lock-out mechanism selectively locks out one of the axes of rotation of the multi-axis swivel joint.

The disclosure relates to a robot cleaner. The robot cleaner comprises a main body; a plurality of spin mop assemblies disposed at a lower portion of the main body and configured to include at least one mop pad attached at lower portions of the plurality of spin mop assemblies; a driving assembly configured to drive the plurality of spin mop assemblies; a first supply assembly configured to store a first liquid inside the main body and supply the first liquid to at least one mop pad of some of the plurality of spin mop assemblies by adjusting a first valve; and a second supply assembly configured to store a second liquid inside the main body and supply the second liquid to at least one mop pad of the others of the plurality of spin mop assemblies by adjusting a second valve.

A cleaner includes a first cleaning module including a left spin mop and a right spin mop that come into contact with a floor while rotating in a clockwise direction or in a counterclockwise direction when viewed from an upper side, a second cleaning module that comes into contact with the floor at a position spaced apart from the left spin mop and the right spin mop in a forward-and-backward direction, a body supported by the first cleaning module and the second cleaning module, and a water supply module that supplies water to the first cleaning module. A water tank is disposed inside the body. Water supplied by the water supply module reaches the first cleaning module before reaching the floor.

A portable power and water supply for hard surface or carpet cleaners is disclosed. The portable power and water supply can include a portable platform with a fresh/waste water tank and two or more power connectors that can be coupled to separate power sources. The fresh/waste water tank can have an internal bladder that separates fresh cleaning water from returned waste water. The fresh/waste water tank can facilitate operation of cleaning tools (e.g., hard surface cleaners and/or carpet cleaners) in buildings with limited or widely spaced water supplies, without the need for long hoses. The power connectors can be coupled to wall power to direct power to the cleaning tools.

An autonomous coverage robot detection system includes an emitter configured to emit a directed beam, a detector configured to detect the directed beam and a controller configured to direct the robot in response to a signal detected by the detector. In some examples, the detection system detects a stasis condition of the robot. In some examples, the detection system detects a wall and can follow the wall in response to the detected signal.
