An autonomous vacuum cleaner includes an outer housing, a suction nozzle, and a suction motor and a fan assembly operable to generate an airflow through the vacuum cleaner from the suction nozzle through a debris separator to a clean air exhaust. A fan of the fan assembly is rotatable about an axis of rotation of the suction motor and the fan assembly. The debris separator includes a cyclonic separator operable to separate debris from the airflow, the cyclonic separator located within the housing and includes a cylindrical wall along a longitudinal axis and having a first end and a second end, a dirty air inlet, a clean air outlet, a debris outlet adjacent the second end of the cylindrical wall, and a dust bin in fluid communication with the debris outlet of the cyclonic separator, where the cyclonic separator is coaxial with the motor and fan assembly.

A vacuum cleaner having a filter cleaning mechanism that is manually actuable while the vacuum cleaner is fully assembled is disclosed. A housing of the vacuum cleaner has an exterior side and an interior side, and a channel extends through the housing from the exterior side to the interior side. A filter brush is in contact with a side of the vacuum filter, and a rod extends slidably through the channel in the housing and is coupled to the filter brush. A handle is coupled to the rod, and movement of the handle slides the rod through the channel and moves the filter brush along the side of the vacuum filter to remove debris from the filter. The handle may be rotatable, and the filter cleaning mechanism may include a bellows or a sealing member.

A dust cup assembly and a handheld cleaner having the same are provided. The dust cup assembly includes: a negative pressure device configured to suck and blow an airflow; a dedusting device configured to remove dust from the airflow; and a casing including a cup body with an open top and a cleaner cover disposed at the top of the cup body, in which the cup body includes a mounting frame and a dust collecting cup, the dedusting device is supported on a top of the mounting frame, the negative pressure device is mounted to a bottom of the mounting frame, and the dust collecting cup is covered outside the negative pressure device and connected to the mounting frame.

A cleaner includes: a suction motor that generates suction force; a dust separation unit that separates dust from air sucked by the suction force; a motor housing that covers the suction motor; a flow guide that surrounds an outer side of the motor housing and guides air discharged from the dust separation unit to the suction motor; and a body that forms an external appearance by surrounding the flow guide and guides air discharged from the suction motor together with the flow guide.

A dust collecting apparatus may include a first dust separator configured to separate dust from suctioned air; a first dust storage chamber configured to store the dust separated in the first dust separator; a support tube and a pressing plate coupled to the support tube; a second dust separator configured to separate dust from the air which has passed through the first dust separator; and a second dust storage chamber configured to store the dust separated in the second dust separator, and located inside of the support tube.

There is provided a robot cleaner having an improved dust-collecting capability and an improved suction force and capable of being manufactured in a small size. The robot cleaner includes a main body comprising a fan motor and having a suction port provided in one side thereof; a plurality of cyclone units configured to separate foreign substances in air suctioned through the suction port; and a plurality of suction flow paths connecting the plurality of cyclone units and the suction port.
