Abstract: The present disclosure relates to a cleaner, more particularly, a cleaner capable of minimizing the pressure loss by minimizing the number of bending of the flow direction of the air flowing inside the cleaner and, at the same time, providing comfort to the user since the vibration occurring in the suction motor during the cleaning operation is not transmitted to the user, and the cleaner includes a pre-filter disposed upstream of the suction motor and configured to filter dust contained in the air, and a HEPA filter disposed downstream of the suction motor and configured to filter dust contained in the air, and at least one among the pre-filter and HEPA filter is disposed on an extension line of a center axis about which the suction motor rotates.

Abstract: Disclosed is a cleaner station including a first station with which a hand vacuum cleaner can be combined and a second station with which a robotic vacuum cleaner can be combined. The first station may include a first suction portion which sucks dust from a dust bin of the hand vacuum cleaner. The second station may include a second suction portion which sucks dust from a dust bin of the robotic vacuum cleaner. The cleaner station may include a dust inlet where the dust sucked by the first suction portion and the second suction portion is discharged. The cleaner station may include a dust storage box which communicates with the dust inlet and receives the dust sucked by the first suction portion and the second suction portion.

Abstract: A robot cleaner includes a cleaner body, a suction unit, and a cyclone unit. The cyclone unit has a first suction opening and a second suction opening for sucking air, and a first cyclone and a second cyclone for passing air therethrough, the air having dust filtered therefrom by a centrifugal force. A first guiding member and a second guiding member extend upwardly from the suction unit toward the cyclone unit with an inclination angle, the first guiding member for connection between the suction unit and the first suction opening, and the second guiding member for connection between the suction unit and the second suction opening. A dust box communicated with a dust discharge opening is provided at a front side of the cyclone unit so as to collect dust filtered by the cyclone unit. The dust box is partially or wholly accommodated between the first and second guiding members.
