A vacuum cleaner includes an improved dual-action filter cleaning mechanism using both a rotational flicking action and a vertical shaking action. A debris removal assembly of the vacuum cleaner can include a filter assembly having a first filter and a second filter arranged in a nested configuration, and a filter cleaning mechanism configured to impart a combination of vertical shaking of the first filter and rotational flicking of the second filter. The filter cleaning mechanism can include a camming mechanism configured to simultaneously move the first filter along the axis and rotate the first filter about the axis while the second filter remains stationary

An auto clean machine, comprising: a chassis; a first light source, configured to emit first light; a second light source, configured to emit second light; an optical sensor, configured to sense optical data generated according to reflected light of the second light or according to reflected light of the first light; and a control circuit, configured to analyze optical information of the optical data; wherein if the first light source is activated, the second light source is de-activated and the control circuit determines variation of the optical information is larger than a variation threshold, the control circuit changes the first light source to be non-activated and the second light source to be activated.

A dust collector in one aspect of the present invention comprises a dust collection portion, a communication portion, and an interlock operation control portion. When the communication portion receives an interlock command transmitted from an electric working machine, the interlock operation control portion makes the dust collection portion operate interlocking with the electric working machine. The interlock operation control portion includes a storage portion, in which identification information specific to the electric working machine with which the dust collection portion is to be made to perform the interlock operation is stored.

A vacuum cleaner motor device comprises a motor assembly and an expansion assembly. The motor assembly further comprises a rotor, a stator, and a main shaft. The expansion assembly further comprises a first motor support, a second motor support, a fan blade member, a fan blade member support, a PCBA assembly, a first bearing, and a second bearing. The rotor is a neodymium iron boron magnet made of neodymium iron boron, which ensures that the motor has a strong output power such that the rotating speed of the motor reaches more than 100,000 rpm. The outer circumferential diameter of the fan blade member ranges from 35 to 40 mm. Compared with conventional vacuum cleaners, the fan blade member of the present disclosure has a larger size, which ensures a stronger vacuum suction force of the vacuum cleaner and achieves better cleaning effect.

A method of controlling a moving robot is provided. The method of controlling a moving robot includes the steps of: (a) performing a basic motion of the moving robot which moves on a rotating mop; (b) measuring the slip rate of the moving robot; and (c) controlling the travel of the moving robot.

An interlocking adapter in one aspect of the present disclosure includes a current path, an electric load, a switch, and a controller. The controller turns on and off the switch in synchronization with a change of an alternating-current voltage received from an electric outlet of an electric apparatus in response to reception of an interlocking command signal from a working machine so as to supply a load current from the electric outlet to the electric load. The controller turns on and off the switch at a specified ratio of a time every ½ cycle of the alternating-current voltage.

The present invention is directed to a blowervac device having a grill that requires to distinct steps in securing the grill over a fan to activate a safety switch allowing power to the motor. The grill has an outer ring and a rotatable inner cover. The first step is simply to secure the grill over the fan. The second step requires the cover to be rotated, which activates an actuator for the safety switch, allowing power to be delivered to the motor and operation of the device. This two-step process reduces the likelihood if inadvertent operation of the device and reduces the chances of injury.

A mobile robot and a control method therefor, according to the present invention, are configured to determine whether a received signal is a pre-set signal and distinguish noise caused by overlapping of signals to control the operation of a sensor for detecting an obstacle according to an operation state of a main body such that transmission of a detection signal is limited, and thus has effects of the obstacle being easily detected by distinguishing each signal, the main body returning to a charging stand, and signal interference being minimized for a plurality of sensors using a signal of the same wavelength band.

A floor treatment appliance with a replaceable change component, a detection device for detecting an actual parameter that is influenced by wear of the change component, an evaluation device for determining a degree of wear of the change component based on the actual parameter and a communication device for communicating information concerning a required replacement of the change component to an external terminal that is communicatively linked to the floor treatment appliance. The change component is a floor treatment element that mechanically acts upon a floor surface to be treated, and the evaluation device calculates an average value of the actual parameter detected by the detection device referred to a defined time period of at least one hour, compares the average value with a defined reference value and determines the degree of wear of the change component in dependence on the result of the comparison.
