An extractor cleaning machine that includes a base having a base exhaust duct having an exhaust outlet directed toward a surface being cleaned. The extractor further includes a suction source that is operable to generate an airflow that is discharged through the exhaust outlet of the base and onto the surface, which is configured to at least partially dry the surface. The extractor further includes a body pivotally coupled to the base such that the body is pivotable between an upright position and an inclined position, and the body includes a body exhaust duct that is movable relative to the base exhaust duct as the handle pivots between the upright position and the inclined position. The base exhaust duct and the body exhaust duct cooperate to form an exhaust passageway between the suction source and the exhaust outlet.

A floor cleaning apparatus (1) has an air suction unit (10) and an outlet channeling unit (30), which connects an outlet side of the suction unit (10) to an exhaust aperture (40). The air outlet channeling unit (30) includes various expansion chambers (31, 32, 34, 39) and respective air compression channels interposed among the expansion chambers. At the first expansion chamber (31) an intercepting wall (100) with through holes (101) may be present.

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.

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.

A floor cleaning apparatus (1) is provided including a cleaning assembly (500), a suction unit (10), an inlet channeling unit (20), and an outlet channeling unit (30). The suction unit (10) has a motor (11) and an impeller (12). The inlet channeling unit (20) is in fluid communication with at least one portion of the cleaning assembly (500). The outlet channeling unit (30) connects the suction unit (10) to an exhaust aperture (40). The outlet channeling unit (30) includes a first expansion chamber (31) and at least one intercepting wall (100). The first expansion chamber (31) faces the outlet side of the impeller (12). The at least one intercepting wall (100) comprises a plurality of through holes (101). The intercepting wall (100) operates inside the first expansion chamber (31).

The embodiment of the present disclosure provides a cleaning device, which includes a power module, a vacuum cleaner module, and a surface wet cleaner module. The power module includes a power assembly and a motor assembly that are connected to each other. The vacuum cleaner module includes an air suction assembly, a dust collection assembly, and a filter assembly that are sequentially communicated, and the vacuum cleaner module has a first mounting position that is configured to be connected and matched with the power module. The surface wet cleaner module includes a floor brush and a body, and the body has a second mounting position that is configured to be connected and matched with the power module.

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.

A surface cleaning apparatus has a base configured to be moved across a surface to be cleaned, a fluid delivery system, and a fluid recovery system with a suction nozzle assembly defining a fluid flow path. A squeegee is provided in the suction nozzle assembly and is mounted within the fluid flow path to slide forwardly and rearwardly within the suction nozzle assembly as the base is moved rearwardly and forwardly, respectively.

A mobile floor scrubber includes an orbital scrub head attached to a forward portion of its chassis. The scrubber head includes a rotary motor, an eccentric drive assembly and a floor engaging scrubbing pad which engages and cleans the floor. The eccentric drive mechanism introduces vibration in the orbital scrub head which is transferred to the chassis which reduces the energy used to perform the scrubbing task and reduces the operating efficiency of the floor scrubber. The floor scrubber further includes a cleaning fluid delivery system for providing a cleaning fluid to the scrubbing pad for application to the floor during the cleaning operation. The scrub head includes a first upper plate and a second lower plate arranged in vertically spaced relation, with both plates being generally planar and rectangular in shape. Disposed between and coupled to the upper and lower plates are plural spaced vibration isolators to reduce the transmission of vibration from the lower plate produced by action of the eccentric drive assembly to the upper plate and to isolate the floor scrubber's chassis from this vibration. Any vibration produced in the scrub head is further prevented from transmission into the scrubber's chassis by mounting the scrub head in closely spaced relation relative to the motor's rotary axis.
