A method for adaptively operating a cleaning robot based on height difference between floors and the cleaning robot are provided, and according to an embodiment of the present disclosure, the cleaning robot that adaptively operates based on the height difference between the floors includes a central controller that controls a height adjuster that controls a height of a floor cleaner based on height information related to a space stored in a map storage and height information sensed by a sensor.

Systems and methods for navigating an autonomous vacuum are disclosed. According to one method, the autonomous vacuum traverses a cleaning environment having a plurality of surfaces. As the autonomous vacuum is traversing the cleaning environment, sensors on the autonomous vacuum capture sensor data describing a first section of a surface on which the autonomous vacuum is currently traversing. Based on the received sensor data, the autonomous vacuum can determine that the first section is of a first surface type of a plurality of surface types. The autonomous vacuum can generate a user interface with a background displaying the determined first surface type to notify the user of where the autonomous vacuum is cleaning.

A cleaning machine may include: a first brush comprising a first brush shaft extending in a left-right direction and a first brush body held by the first brush shaft; a second brush comprising a second brush shaft extending in the left-right direction and a second brush body held on the second brush shaft; a brush supporting member supporting each of the first brush and the second brush such that the first brush and the second brush are rotatable; a body supporting the brush supporting member such that the brush supporting member is pivotable; and a pivot mechanism configured to pivot the brush supporting member with respect to the body. At least the first brush may move with respect to the body in an up-down direction when the brush supporting member pivots with respect to the body.

The present disclosure provides an adjusting structure of a floor brush wheel, which includes a bottom housing, a top housing, a transmission member, a first pulley assembly, and a second pulley assembly. The bottom housing and the top housing are fastened to form a receiving cavity. The transmission member is received in the receiving cavity and movably connected to the bottom housing. The first pulley assembly and the second pulley assembly are movably connected to the bottom housing, respectively. One end of the transmission member abuts against the first pulley assembly, and the other end of the transmission member abuts against the second pulley assembly. When the transmission member slides in a first direction, the first pulley assembly and the second pulley assembly are pressed by the transmission member to slide in a direction away from the bottom housing.

The present disclosure provides a vacuum cleaner floor brush with a height-adjustable suction inlet. The vacuum cleaner floor brush includes a floor brush main body, a rolling brush, and a rolling brush cover with an arc-shaped cross section; the rolling brush is fixedly mounted on a preset rolling brush chamber on the floor brush main body; the floor brush main body is provided with a suction inlet adjustment plate; an inner wall of the suction inlet adjustment plate is a cambered surface; a lengthwise direction of the suction inlet adjustment plate is parallel to an axial direction of the rolling brush; two opposite ends in a width direction of the suction inlet adjustment plate respectively extend towards the rolling brush cover and a bottom suction inlet of the floor brush main body; and the suction inlet adjustment plate can flip along a circumferential direction of the rolling brush. In the present disclosure, more than two kinds of different rolling brushes can be mounted on the same floor brush for use. When different rolling brushes are used on different floors, the suction inlet adjustment plate can be adjusted up and down to make the height of the suction inlet change, so as to improve the cleanness of the floor brush.

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 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 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 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.

Disclosed is a cleaning unit comprising a variable brush portion. The cleaning unit according to an embodiment of the present invention comprises a shaft capable of reciprocating along an axial direction, wherein a first cam protrudes from the outer circumferential surface of the shaft. In addition, the brush portion is arranged on the outer circumferential surface of a body member surrounding the shaft, and the brush portion includes a second cam engaged with the first cam. When the shaft is moved in the axial direction, the first cam pushes the second cam in a radial direction, whereby the brush portion may protrude in the radial direction. That is, as the shaft reciprocates in the axial direction, the length of the brush portion protruding from the outer circumferential surface of the body member may vary.
