A surface cleaning apparatus includes a housing including an upright handle assembly and a base mounted to the handle assembly and adapted for movement across a surface to be cleaned. A fluid delivery system can be provided on the housing and can include a fluid supply chamber and a fluid dispenser. A fluid recovery system can be provided on the housing and include a suction nozzle assembly, a recovery chamber, and a vacuum source to draw fluid from the surface to be cleaned.

An autonomous coverage robot includes a chassis, a drive system configured to maneuver the robot, and a cleaning assembly. The cleaning assembly includes a cleaning assembly housing and at least one driven sweeper brush. The robot includes a controller and a removable sweeper bin configured to receive debris agitated by the driven sweeper brush. The sweeper bin includes an emitter disposed on an interior surface of the bin and a receiver disposed remotely from the emitter on the interior surface of the bin and configured to receive an emitter signal. The emitter and the receiver are disposed such that a threshold level of accumulation of debris in the sweeper bin blocks the receiver from receiving emitter emissions. The robot includes a bin controller disposed in the sweeper bin and monitoring a detector signal and initiating a bin full routine upon determining a bin debris accumulation level requiring service.

The present disclosure provides a surface cleaning apparatus that includes a housing including a base adapted for movement across a surface to be cleaned, a fluid delivery system, and a recovery system. The surface cleaning apparatus can be configured to clean multiple surfaces, including hard and soft surfaces, and for different cleaning modes, including wet cleaning, dry vacuum cleaning, and self-cleaning. Methods for self-cleaning a surface cleaning apparatus are also provided.

An extractor cleaning machine includes a supply tank configured to store a cleaning fluid and a base configured to be movable along a surface to be cleaned. The base includes a suction nozzle and an aperture configured to spray the cleaning fluid onto the surface. The extractor cleaning machine also includes a recovery tank in fluid communication with the suction nozzle and a suction source in fluid communication with the suction nozzle and the recovery tank. The suction source is configured to draw the cleaning fluid through the suction nozzle and into the recovery tank. The extractor cleaning machine further includes a body pivotally coupled to the base between an upright position and an inclined position. The body includes an outlet in fluid communication with the suction source such that an airflow generated by the suction source is discharged from the outlet toward the surface.

A cleaning apparatus according to one or more embodiment may include a moving body configured to move on a surface in a moving direction; and a cleaning unit provided in the moving body and is configured to clean the surface to be cleaned. The cleaning unit may include: an intake nozzle; an intake unit configured to suction in objects, along with air, from the surface to be cleaned through the intake nozzle; a collection container configured to separate the objects that are suctioned in and collect the objects in an inside of the collection container; an air discharge duct configured to guide air suctioned in by the intake unit from an air outlet of the intake unit to an inside of the cleaning unit; and a cover member that covers at least the air discharge duct, and is configured to form an internal space with the air discharge duct.

The moving robot using artificial intelligence includes: a traveling unit to move a main body; an operation unit to perform a specific operation while generating noise; a sensing unit to sense an ambient situation during traveling; and a controller to determine whether a specific activation condition is satisfied, based on situation information sensed by the sensing unit, and, when the activation condition is determined to be satisfied during traveling, perform a control action to activate a low noise mode so that the operation unit performs the specific operation with relatively reducing the noise. The control method using artificial intelligence includes: determining whether a specific activation condition is satisfied, based on situation information acquired by sensing an ambient situation during traveling; and, when the activation condition is determined to be satisfied, performing a specific operation in an activated state of a low noise mode in which noise is relatively reduced.

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; and a lifting structure, connected to the wet cleaning module and configured to enable the wet cleaning module to move upward or downward with respect to the mobile platform; wherein the wet cleaning module includes: a cleaning head configured to clean the cleaning surface; and a driving unit configured to drive the cleaning head to conduct reciprocating movement on a target surface which indicates a part of the cleaning surface.
