Provided is a cleaner having improved cleaning efficiency. The cleaner includes a main body having a intake provided to suction an object to be cleaned and a suction device having a brush chamber that communicates with the intake and a brush accommodated in the brush chamber, wherein the brush includes a brush body rotatably coupled to the brush chamber, a blade protruding in a radial direction of the brush body, and prevention members formed to be inclined from a central portion of the brush body to opposite side ends of the brush body to prevent foreign substance introduced into the brush chamber from being wound around the blade.

The present disclosure provides a sweeping robot obstacle avoidance treatment method based on free move technology, step 1 and step 2 are as following. Step 1: predetermining a sweeping robot provided with a six-axis gyroscope, a grating signal sensor, and a left-and-right-wheel electric quantity sensing unit. Step 2: performing a real-time sensing and data acquisition on an operation state of the sweeping robot by utilizing the six-axis gyroscope, the grating signal sensor, and the left-and-right wheel electric quantity sensing unit to obtain a real-time data information.

An autonomous cleaning device (1), such as a robotic vacuum (1), has an optical sensor (50) that includes: a rotary body (51) configured to rotate relative to a main body (2) about a rotational axis (CX); a light-emitting device (61) provided on the rotary body; a light-receiving device (62) provided on the rotary body; a cover (52) disposed upward of the rotary body; and legs (70) disposed around the rotary body and supporting the cover. In a cross section orthogonal to the rotational axis, at least a portion of a surface of each of the legs is inclined with respect to a virtual radial line (RL) extending in the radial direction of the rotational axis.

Provided is a robot cleaner using an artificial intelligence (AI) algorithm and/or a machine learning algorithm in a 5G environment connected for Internet of Things (IoT). The robot cleaner includes one or more sensors, a driving wheel, a suction blower, and a controller, and the controller defines a cleaning target area, identifies a user's location and a type of the user's behavior, collects life pattern information of the user including the user's location, the type of the user's behavior, and timestamps each associated therewith during the time period of one day or more, determines a cleaning schedule of the robot cleaner based on the collected life pattern information, and controls the driving wheel and the suction blower so as to perform cleaning in accordance with the determined cleaning schedule.

A cleaner is disclosed, which comprises a main body including an suction inlet through which air containing dust enters, a dust separator provided to separate dust from the air while the air entering from the suction inlet is moving, a first dust collector configured to collect the dust separated by the dust separator, a cyclone portion configured to rotate the air to separate the dust from the air, and a second dust collector collecting the dust separated by the cyclone portion. The dust separator is provided with a plurality of plate shaped members arranged at a predetermined angle with respect to a moving direction of the air, and arranged to be spaced apart from one another to move the air.

An apparatus includes a frame, a drive assembly supported by the frame, an electronic system supported by the frame, and a cleaning assembly coupled to the frame. The drive assembly is configured to move the frame along a surface. The cleaning assembly is configured to engage the surface to transfer detritus from the surface to a storage volume supported by the frame. The electronic system has at least a processor and a memory. The processor is configured to define a path along which the drive assembly travels and is configured to redefined a path along which the drive assembly travels based on at least one signal received from at least one sensor.

An autonomously traveling vehicle includes a main body, a storage, an autonomous travel plan generator and a traveling controller. The main body includes a traveling carriage. The storage stores partial traveling route data generated for subareas including an individual coordinate system, and route connection data connecting the partial traveling routes. The autonomous travel plan generator generates an autonomous traveling schedule for autonomous travel by associating the selected partial traveling route data and the selected route connection data that connects the partial traveling routes. The traveling controller controls the traveling carriage in accordance with the autonomous traveling schedule to move the main body.
