A cleaning pad for an autonomous cleaning robot evenly wets and collects debris for cleaning operations. The pad includes a core of absorbent layers for absorbing liquid through capillary action and for distributing the liquid within the cleaning pad. The pad includes a wrap layer around the core, the wrap layer comprising a fibrous layer that is flexible and absorbent, the fibrous layer configured to absorb liquid through capillary action and transfer the liquid to the core. The pad includes one or more transition regions spanning a cleaning width of the cleaning pad, the one or more transition regions dividing the cleaning pad into at least two segments. The forward positioned segment of the pad, of the at least two segments of the pad, has a lesser thickness compared to a thickness of an aft positioned segment of the at least two segments.

A robot cleaner is disclosed, which comprises a main body forming an external appearance, a water bucket unit provided in the main body, supplying water to a water mop, a driving wheel rotated by a rotational force of a driving motor provided in the main body, moving the main body, and a wiper module provided in the water bucket unit, wherein the wiper module is extended to front and rear directions of the driving wheel and formed to be protruded toward the floor where the main body drives.

A method for processing a map of a closed space is provided. The method includes obtaining a plurality of self-locations of a mobile device. The method also includes obtaining a plurality of obstacle locations. The method also includes obtaining a boundary profile based on the obstacle locations, the boundary profile being a closed line formed by sequentially connecting multiple adjacent obstacle locations. The method also includes obtaining a self-circle based on the self-locations of the mobile device, the self-circle being a closed line formed by sequentially connecting multiple adjacent self-location of the mobile device. The method also includes determining the boundary profile as an outer profile when the boundary profile encircles the self-circle at an outer side of the self-circle. The method further includes processing the map of the closed space based on the outer profile.

A vertical surface cleaning device comprising a main body, a cleaning arm, a cleaning head, and leg mechanisms with grippers. The cleaning head applies a cleaning fluid on a surface to carry out a cleaning operation. A waste collector is provided to collect a waste material arising from the cleaning operation. The grippers may remain in a grip or in a release state. The segments of the leg mechanisms are articulatable to configure a first group of the leg mechanisms to stably hold the main body at a first place with the grippers remaining in the grip state. A second group of the leg mechanisms move in a desired direction with their grippers in release state while the first group stably holds the main body. The first group of the leg mechanisms then moves in the same direction while the second group holds the main body at a second place.

The present disclosure relates to a blockage and a smart cleaning device. The blockage includes a plug body and a hierarchical sealing structure. The plug body is a shaft-shaped structure as a whole, and is provided with a through hole that penetrates the plug body. The hierarchical sealing structure is sleeved on an outer side of the plug body, and is provided with at least two annular plugs stacked in an axial direction of the plug body.

The present disclosure provides a cleaning robot, a cleaning module, a cleaning assembly, a base and a cleaning system, wherein the cleaning robot includes: a robot apparatus, configured to carry the cleaning module; and a first replacement mechanism, configured to enable the robot apparatus to be loaded with the cleaning module, and replace a cleaning module carried on the robot apparatus with the loaded cleaning module. When the cleaning robot is loaded with a new cleaning module, the loaded new cleaning module replaces the old cleaning module originally carried on the cleaning robot, in this way, the assembling and disassembling of the cleaning modules on the cleaning robot can be performed synchronously.

The invention relates to a cleaning device, in particular a suction wiper, having a housing with at least one cleaning medium for receiving a cleaning agent, having a cleaning medium carrier for receiving the cleaning medium, having a drive for driving the cleaning medium carrier and having a controller. At least one vibration sensor for detecting a strength of a vibration is arranged in the housing and the controller is designed to determine the moisture of the cleaning medium, the controller evaluating a change in the strength of the vibration. The invention also relates to a method for operating a cleaning device.

An autonomous cleaning device, includes: a mobile platform, configured to move autonomously on a cleaning surface; and a cleaning module, disposed on the mobile platform and including a wet cleaning module, configured to clean at least part of the cleaning surface in a wet cleaning mode.

A surface cleaning apparatus such as an extractor has a fluid flow path extending from a dirty fluid inlet head to a clean air outlet. The fluid flow path upstream of the separation stage comprises a removable portion.

A mobile robot configured to travel across a residential floor or other surface while cleaning the surface with a cleaning pad and cleaning solvent is disclosed. The robot includes a controller for managing the movement of the robot as well as the treatment of the surface with a cleaning solvent. The movement of the robot can be characterized by a class of trajectories that achieve effective cleaning. The trajectories include sequences of steps that are repeated, the sequences including forward and backward motion and optional left and right motion along arcuate paths.
