A cleaner includes a suction unit guiding air and dust, a main body including a first cyclone unit separating the air and the dust, which are suctioned through the suction unit, from each other and a second cyclone unit separating the dust from the air discharged from the first cyclone unit, and a guide unit disposed in the main body to partition a first dust storage part, in which the dust separated in the first cyclone unit is stored, and a second dust storage part, in which the dust separated in the second cyclone unit is stored, from each other. The guide unit is separably coupled to the main body, and when the guide unit is separated from the main body, a dust discharge part of the second cyclone unit is exposed to the outside.

Methods and apparatus for cleaning a surface with a cleaning device having a body with a handle, a connector, and one or more cleaning heads that are removably attached to the cleaning device. Each cleaning head include a lower surface arranged to contact a surface to be cleaned and a dirt collection chamber permanently attached to the cleaning head. The cleaning head may include a support structure to support the dirt collection chamber and a cleaning sheet. The cleaning head also may include a suction nozzle. At least a portion of the dirt collection chamber may be made of a filter material.

A dust collector includes a tank, a main body, a suction fan, a flexible pre-filter, and a main filter. The tank includes a suction opening. The main body is fixed to an upper portion of the tank. The suction fan is disposed at the main body. The suction fan is rotated by a motor. The flexible pre-filter is housed in the tank at a lower side of the main body. The pre-filter is positioned at an upstream side of external air suctioned from the suction opening. The main filter is positioned at a downstream side of the pre-filter. The main filter has a plate shape disposed laterally.

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.

The present invention relates to a blowing-suction device. The blowing-suction device includes: a housing, having a first opening connected to the outside; an air tube, connected to the housing; an air flow generation apparatus that operably generates an air flow, where when the blowing-suction device is in the blowing mode, the air flow is blown out from the air tube, or when the blowing-suction device is in the suction mode, the air flow is sucked from the air tube; and a collection apparatus, configured to collect an object sucked by the blowing-suction device in the suction mode, where the collection apparatus is connected to the first opening both in the blowing mode and in the suction mode, and the collection apparatus further includes an air admission portion, and in the blowing mode, the air admission portion is open; or in the suction mode, the air admission portion is closed.

An autonomous mobile robot includes a body, a drive supporting the body above a floor surface, a light-propagating plate positioned on the body and having a periphery defining a continuous loop, light sources each being positioned to direct light through a portion of the plate to a portion of the continuous loop, and a controller to selectively operate the light sources to provide a visual indicator of a status or service condition of the autonomous mobile robot. The drive is configured to maneuver the mobile robot about the floor surface.

A hand vacuum cleaner has an information display device provided on a rear wall of the rear end of the hand vacuum cleaner.

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.

The present invention provides an accessory 20 for use with, and adaptable to be releasably connected to, a vacuum cleaner 1. The accessory 20 comprises a vacuum intake head 21 having a chamber 21a arranged such that when the accessory 20 is connected to the vacuum cleaner 1, the chamber 21a is in fluid communication with the vacuum cleaner 1 and adaptable to receive air and liquid from and around the surface to be cleaned. The accessory 20 further comprises a filtration device 40 adaptable to separate the liquid from the air such that substantially no liquid returns to the vacuum cleaner 1. The accessory 20 can be used with both portable and central vacuum cleaners 1.
