A vacuum cleaner that includes: a cleaner body; a wheel; a dust container; a cover member that is configured to (i) rotate, about an axis that is outside of a plane of the cover member, between a first position and a second position and (ii) cover, based on the cover member being located at the first position or the second position, the first opening of the cleaner body and a portion of the dust container; a cover member coupling portion that couples the cover member to the cleaner body and that is configured to rotate about the second axis with the cover member; a suction nozzle that is coupled to the dust container and that is configured to guide dust into the dust container; and a display that is coupled to the cover member and that is configured to display operating information of the vacuum cleaner is disclosed.

An electric vacuum cleaner and an electric vacuum cleaning apparatus that can accumulate dust intensively near its waste lid and can readily discharge the accumulated dust. An electric vacuum cleaner includes: a first separator that separates dust from dust-containing air; a coarse-dust collecting chamber that accumulates the dust separated with the first separator; a coarse-dust waste-outlet that discharges the dust from the coarse-dust collecting chamber; a recess part provided within the coarse-dust collecting chamber, communicates with the coarse-dust waste-outlet, and accumulates dust inside the coarse-dust collecting chamber; and a waste-outlet lid that is part of a wall of the recess part and opens and closes the coarse-dust waste-outlet.

A dust collection box and a robot vacuum cleaner are disclosed. The dust collection box is used in the robot vacuum cleaner. The dust collection box includes a box body, a filter holder arranged in the box body, a dust separation structure configured to block dust, and a filter. The box body defines an air inlet and an air outlet. The filter holder defines an opening in a side surface thereof. The dust separation structure is arranged in the box body and located at an air inlet side of the opening. The filter is arranged to the filter holder and located at an air outlet side of the opening.

A surface cleaning apparatus has a cyclone chamber provided in an air flow path. The cyclone chamber has a screen assembly with an outlet section, a longitudinally spaced apart distal section and a longitudinally extending porous section. The outlet section includes a non-porous member extending longitudinally inwardly an outlet section length from an outlet end of the outlet section to a longitudinally inwardly positioned inlet end of the outlet section. The outlet end of the outlet section overlies a cyclone air outlet. The porous section extends longitudinally inwardly from an outlet end of the porous section that is located at the inlet end of the outlet section. The inlet end of the outlet section has a width in a direction transverse to the longitudinal direction that is greater than a width of the outlet end of the porous section in the transverse direction.

A dirt separator for a vacuum cleaner includes a chamber having an inlet through which dirt-laden fluid enters and an outlet through which cleansed fluid exits the chamber. A disc located at the outlet rotates about a rotational axis and comprises holes through which the cleansed fluid passes. The inlet is defined by an end of an inlet duct that extends within the chamber, and a separation distance between the centre of the inlet and the centre of the disc is no greater than the diameter of the inlet.

A dirt separator for a vacuum cleaner including a chamber having an inlet through which dirt-laden fluid enters the chamber and an outlet through which cleansed fluid exits the chamber; and a disc located at the outlet, the disc being arranged to rotate about a rotational axis and including holes through which the cleansed fluid passes. When viewed normal to the disc, each hole is elongate and defines a longitudinal axis which runs within the plane of the disc. The longitudinal axis of each hole is inclined relative to the radial direction of the disc.
