A cleaning robot includes a main body, a drive assembly and a cleaning assembly. The main body includes a bottom part. The cleaning assembly includes a mounting part, a wiping part and a release part. The mounting part is positioned on the bottom part. The mounting part includes a first rail, a second rail, and a first positioning part. The wiping part is positioned on the mounting part and includes a second positioning part, the wiping part is movable from first ends of the first rail and the second rail to second ends thereof until the second positioning part abuts against the first positioning part whereby the wiping part is fixed on the mounting part. The release part is positioned on the mounting part and configured to separate the second positioning part from the first positioning part whereby the wiping part is detached from the mounting part.

The present invention relates to a robot cleaner. The robot cleaner comprises: a cleaner body equipped with a driving wheel; and a cleaning nozzle mounted inside a downwardly open opening portion in a lower portion of the cleaner body so as to be able to ascend and descend. The cleaning nozzle can be supported by a plurality of ascending/descending guides and a plurality of auxiliary ascending/descending guides so that the cleaning nozzle can ascend and descend relative to the cleaner body according to changes in the height of a cleaning surface on which the cleaner body travels. Accordingly, the cleaning to nozzle rises upon being pressed by a compressible floor such as a carpet, thus solving the problem of the cleaning nozzle catching on the cleaning surface. Therefore, travel performance can be improved, and the load on a brush driving part can be reduced.

A cleaning bin mountable to an autonomous cleaning robot operable to receive debris from a floor surface includes a debris compartment to receive a first portion of debris separated from the airflow and a particulate compartment to receive a second portion of debris separated from the airflow. The cleaning bin also includes a debris separation cone having an inner conduit defining an upper opening and lower opening. The upper opening receives the airflow from the air channel. The inner conduit tapers from the upper opening to the lower opening such that the airflow forms a cyclone within the inner conduit.

A robot cleaner includes a main body that autonomously travels, a suction nozzle configured to move up and down or swing with respect to the main body, and a support to support the suction nozzle. The robot cleaner may respond to a change in a height of a floor to improve travel performance and may respond better to obstacles. Even when a height difference of the floor is large, cleaning performance may be improved by maintaining contact and increasing a suction pressure of the suction nozzle.

A surface cleaning apparatus has a suction motor actuator that is actuatable to actuate the suction motor to operate in a first mode of operation and to operate in a second mode of operation, the first mode of operation defining a first discrete power level for the suction motor and the second mode of operation defining a second discrete power level for the suction motor. The first mode of operation is enabled when the first power pack having a first level of power is provided to power the surface cleaning apparatus and the second mode of operation is not enabled until a second power pack is provided such that the surface cleaning apparatus has a second level of on board power that is greater than the first level of on board power.

A vehicle floor mat vacuum machine includes an elongate open mouth communicating with an interior chamber for passage of a floor mat therethrough and between an upper feed roller and a lower brush roller for contacting a carpet surface of the floor mat. A vacuum source connects to a vacuum manifold to create suction, as the brush roller and suction force work in conjunction to remove sand, dirt and other debris from the floor mat. An electric motor, drive belt and reduction gear assembly rotate the feed roller and brush roller in opposite directions with the brush roller rotating at a significantly higher speed. In one embodiment, the vacuum source is a central vacuum system, wherein a solenoid-controlled valve in the vacuum line extending from the feed roller is opened for a timed sequence during operation of the machine.

A robot cleaner comprising: a cleaner body including a controller, the cleaner body having a dust container accommodation part formed therein; a wheel unit mounted in the cleaner body, the wheel unit of which driving is controlled by the controller; and a dust container detachably coupled to the dust container accommodation part, wherein a first opening and a second opening are disposed at the same height in an inner wall of the dust container accommodation part, wherein the dust container includes: an entrance and an exit, disposed side by side along the circumference of the dust container, the entrance and the exit, respectively communicating with the first opening and the second opening when the dust container is accommodated in the dust container accommodation part; and a flow separating part extending downwardly inclined along the inner circumference of the dust container.

A suction device and a suction force adjustment method thereof are provided. A detecting device collects sound generated when the suction device executes a suction operation to obtain characteristics of a sound signal. The detecting device determines a clogging degree of a filter disposed on an exhaust vent of a suction unit, an airflow velocity in a suction pipe, a material of the suctioned surface, and a degree of closure between a suction port of the suction device and the suctioned surface according to the characteristics of the sound signal. A control host adjusts a suction force of the suction unit or adjusts the degree of closure between the suction port of the suction device and the suctioned surface according to a detected result of the detecting device, and provides warning information for cleaning or replacing the filter.

A robotic dust collector includes a suction member having a suction inlet and travels on a cleaning target surface. The robotic dust collector includes a guide member, a support part, and a biasing member. The guide member is disposed at the suction inlet and has a blade part facing the cleaning target surface. The support part supports the guide member in such a manner that allows the guide member to pivot about a pivot axis so as to allow the blade part to move in an up-down direction. The biasing member is configured to exert biasing force on at least a part of the blade part.

A cleaning system has a base unit and a separably connected accessory device. The base unit has a detection device for detecting the type of accessory device connected to the base unit, a base memory and a control device for controlling an operating activity of the base unit and/or the accessory device depending on the type of connected accessory device. The accessory device has a configuration memory, in which configuration data for configuring the base unit and/or the accessory device for an operation of the cleaning system is stored. The control device of the base unit reads the configuration data stored in the configuration memory and stores this configuration data centrally in the base memory. The control device accesses the configuration data stored in the base memory for an operation of the cleaning system and adjusts the base unit and/or the accessory device based on the configuration data.
