The present disclosure relates to a robot cleaner, more particularly, to a robot cleaner that may be escaped from a trapped state by an escaping unit formed in an inner surface of a wheel, when a body of the robot cleaner is caught in a protrusion to put the robot cleaner in a trapped state where the robot cleaner cannot run during the running on the floor of a cleaning area.

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.

A device for receiving signals via an electrically driveable or adjustable furniture element includes a receiving device for receiving at least one wirelessly transmitted signal, and the at least one wirelessly transmitted signal that has been received by the receiving device can be transmitted on to a furniture element. The receiving device is designed such that the at least one wirelessly transmitted signal can be received and processed via a first transmission protocol and a second transmission protocol, wherein the first transmission protocol is different from the second transmission protocol.

A surface treatment apparatus may include a coupling, a handle, an accessory coupled to the coupling, and a toggle proximate the handle. The accessory may have at least two operational states. An actuation of the toggle may cause the accessory to transition between operational states.

A station and a dust removal system including the same are provided. The station according to one aspect of the present specification is a station to which a cleaner including a dust bin and a body cover selectively opening and closing a lower part of the dust bin is coupled, including a coupling body to which the dust bin is coupled and forms a predetermined angle with a ground; a separating unit which separates the body cover from the dust bin; and a dust storage unit which is disposed under the coupling body, the predetermined angle being between 20 degrees and 30 degrees, and the dust bin being slid by gravity and coupled to the coupling body.

The present disclosure provides a cleaning robot, a cleaning module, a cleaning assembly, a base and a cleaning system, wherein the cleaning robot includes: a robot apparatus, configured to carry the cleaning module; and a first replacement mechanism, configured to enable the robot apparatus to be loaded with the cleaning module, and replace a cleaning module carried on the robot apparatus with the loaded cleaning module. When the cleaning robot is loaded with a new cleaning module, the loaded new cleaning module replaces the old cleaning module originally carried on the cleaning robot, in this way, the assembling and disassembling of the cleaning modules on the cleaning robot can be performed synchronously.

The disclosure provides a fan assembly and a vacuum cleaner with the fan assembly. The fan assembly includes a motor, an impeller and a fan housing. The impeller is driven by the motor, which includes an impeller air outlet and an impeller air inlet. The impeller air inlet is located in the axial direction of the impeller, and the impeller air outlet is located in the radial direction of the impeller. An air channel is formed inside the fan housing, and the impeller is at least partially housed in the fan housing. The impeller rotates relative to the fan housing about the rotational axis, the generated airflow enters the air channel during the rotation of the impeller, and the height of the fan housing in the direction of the rotational axis increases along the direction of the air flow.

The present disclosure relates to a mobile robot, and more particularly to a mobile robot, including: a bumper which surrounds at least a portion of an outer circumference of the body; position restoring modules having an elastic member and disposed to be symmetrical to each other; a bumper guide module, having a guide hole and a protruding guider which moves inside the guide hole; and impact sensing modules configured to sense impact and disposed to be symmetrical to each other.

A robotic cleaning system may include a robotic cleaner having a robotic cleaner dust cup and a docking station having a docking station dust cup configured to fluidly couple to the robotic cleaner dust cup. The docking station dust cup may include a first debris collection chamber, a second debris collection chamber fluidly coupled to the first debris collection chamber, and a filter fluidly coupled to the first debris collection chamber and the second debris collection chamber.
