Provided is a vacuum cleaner including a cleaner body; a moving wheel provided at each of both side surfaces of the cleaner body, rotated for travelling of the vacuum cleaner and configured to support the cleaner body to be rotatable in normal and reverse directions; a wheel motor assembly connected to the moving wheel and configured to rotate the moving wheel for the travelling of the vacuum cleaner; a main motor provided inside the cleaner body, located at a rear side further than a vertical extension line of a rotating center of the moving wheel and driven to suction dust; and a battery provided inside the cleaner body, located at the rear side further than the vertical extension line of the rotating center of the moving wheel and configured to provide electric power to the main motor and the wheel motor assembly, wherein a center of gravity of the cleaner body is located at a rear of the vertical extension line of the rotating center of the moving wheel due to an arrangement of the main motor and the battery.

The present concept is a cutting surface and debris container in combination with a vacuum cleaner. The cutting surface and debris container includes a hollow container with a debris storage compartment, and a cutting surface for supporting a workpiece to be cut. The cutting surface has an opening to allow fresh air to be drawn into the container. The top section of the container has an outlet that can connect to a hose which couples the container to a vacuum cleaner. Debris generated from cutting the workpiece is drawn into the container. Large debris particles drop in the debris storage compartment while small particles are extracted by the vacuum cleaner.

A cleaner includes: a main body that has an opening; a suction motor that is disposed in the main body and generates suction force; and a filter unit that includes an exhaust filter for filtering air discharged from the suction motor, the filter unit being inserted into the main body through the opening and being separated from the main body, wherein when the filter unit is combined with the main body, a portion of the filter unit protrudes out of the main body, and a portion of the exhaust filter is positioned inside the main body and the other portion of the exhaust filter is positioned outside the main body.

A cleaner includes: a suction motor that generates suction force; a dust separation unit disposed under the suction motor and separates dust from air; a handle disposed behind the suction motor; and a battery disposed under the handle and behind the dust separation unit to supply power to the suction motor.

The disclosure discloses a cyclonic separating apparatus and a cleaning appliance. The cyclonic separating apparatus includes a downstream cyclonic separating assembly which includes at least one cyclonic separator ring including a plurality of cyclonic separators. Each of the cyclonic separators includes a cyclonic separating drum having an upper side edge communicating with a tangential air duct and a curved duct arranged in an upper portion of the cyclonic separating drum and communicating with the tangential air duct. A spiral rise angle of the curved duct is greater than a half cone angle of an inverted cone drum of the cyclonic separating drum.

A cleaner includes: a main body for separating dust from air suctioned through an opening; a suction motor generating suction force; and a suction part coupled to the opening part and having a connection pipe for guiding the air to the main body. The main body includes a suction guide coupled to one side of the connection pipe including a guide duct having a rotatable flap provided thereto. The suction guide is connected to the guide duct. A suction duct includes: a first surface, where the flap is installed; and a second surface facing the first surface. A second extension line of the second surface forms a first angle with a first extension line of one surface, of the suction guide, connected to the second surface. The first extension line and a third extension line of the flap form a second angle equivalent to or smaller than the first angle.

A hand vacuum cleaner may have an air treatment member and a pre-motor filter downstream from the air treatment member. A suction motor and fan assembly may be is positioned downstream of and below the pre-motor filter, a post motor filter may be positioned downstream of the suction motor and fan assembly and in the lower end of the hand vacuum cleaner. A clean air outlet may be positioned below the suction motor and fan assembly whereby air travels downwardly from the suction motor and fan assembly and through the post motor filter to the clean air outlet.

A hand vacuum cleaner may include a suction motor and fan assembly that is positioned downstream of a pre-motor filter and in an upper end of the hand vacuum cleaner. A post motor filter may be positioned downstream of the suction motor and fan assembly and may be in the lower end of the hand vacuum cleaner. The clean air outlet may be positioned below the suction motor and fan assembly whereby air may travel generally downwardly from the suction motor and fan assembly and through the post motor filter to the clean air outlet.
