A cleaner includes a body, a left spin-mop module located on a left side of the body and a right spin-mop module located on a right side of the body, each of the left spin-mop module and the right spin-mop module being rotatable about a first rotational axis to perform mopping, a left spin-drive unit disposed on the left side of the body, the left spin-drive unit being configured to provide a force to rotate the left spin-mop module; and a right spin-drive unit disposed on the right side of the body, the right spin-drive unit being configured to provide a force to rotate the right spin-mop module. Each of the left spin-drive unit and the right spin-drive unit has a second rotational axis that extend in a direction different from the first rotational axis of the respective left spin-drive unit and the right spin-drive unit.

A robotic cleaning device, along with associated systems and methods of using the same, is described. The device may include a body portion that may define a top surface, a bottom surface, and a continuous sidewall surface. An example device may further include a drive system that propels the robotic device. An example device may further include two or more bottom brushes. An example device may further include a continuous opening that extends around the sidewall surface. An example device may further include a pair of sidewall brushes that may oscillate along the opening.

In an autonomously traveling floor washer, a position estimating unit estimates position data. When a manual operation teaching mode is being executed, a taught data obtaining unit obtains taught position data and a taught cleaning condition at a taught data obtaining time. A cleaning schedule generation unit generates a cleaning schedule. When an autonomous cleaning mode is executed, a cleaning reproduction unit calculates and outputs a reproduced travel control command and a reproduced cleaning condition in an elapsed time based on the cleaning schedule. An elapsed time determining unit determines the taught data obtaining time and the elapsed time.

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.

A floor cleaning machine has one or more work heads, one or more motors for driving one or more work heads via a transmission unit for each work head, wherein each transmission unit has a drive shaft with a co-axial chuck for releasably engaging with the associated work head to rotate the work head. The machine has a liquid reservoir, and at least one liquid conduit extending from the reservoir towards a transmission unit of one of the work heads. The drive shaft has a co-axially extending through-bore receiving a liquid feed tube, the feed tube providing a liquid path for treatment liquid through the transmission unit and through the work head, the feed tube having an upper region for receiving liquid from the conduit and a lower region which feeds through the work head to serve as an outlet for delivering liquid to the underside of the work head.

A cleaner includes a body, a left spin-mop module located on a left side of the body with respect to a centerline of the body, a right spin-mop module located on a right side of the body with respect to the centerline of the body, a left spin motor disposed on the left side of the body with respect to the centerline of the body and having a left spin shaft to provide a force to rotate the left spin-mop module, and a right spin motor disposed on the right side of the body with respect to the centerline of the body and having a right spin shaft to provide a force to rotate the right spin-mop module. The left spin shaft and the right spin shaft extend in a parallel direction of the centerline of the body.

An apparatus is provided having a scrubbing disc that includes sacrificial electrodes of an electrolysis cell.

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.

The present invention provides a cleaning device, including: a device body (10); and a cleaning assembly (20). The cleaning assembly (20) is connected to the device body (10). The cleaning assembly (20) has a first position. A part of the cleaning assembly (20) is located outside a peripheral side of the device body (10) when the cleaning assembly (20) is in the first position. In the present invention, the cleaning assembly is at least partially located outside the peripheral side of the device body, so that the area near an obstacle can be cleaned. The cleaning is more comprehensive, and the cleaning efficiency is improved.
