A hand vacuum cleaner has a cyclone chamber formed of at least two axially extending cyclone chamber sidewall portions wherein one of the portions is pivotally openable. Once opened, a moveable member is translatable to clean or enable cleaning of a screen.

A mobile robot system includes a docking station and a mobile robot. The docking station includes a platform, first and second charging contacts on the platform, and first and second ramp features on the platform. The robot includes a housing, first and second drive wheels, first and second raised charging contacts on a bottom of the housing, and a cleaning module including at least one rotatable cleaning head that extends below the bottom of the housing. The robot is movable from an approach position with the robot spaced apart from a front of the platform to a docked position with the robot on the platform and the docking station charging contacts engaged with the robot charging contacts. As the robot moves from the approach position to the docked position, the robot engages the first and second ramp features and the cleaning mechanism is lifted over the docking station charging contacts.

A cleaner capable of separating a dust separator from a main body and separating a dust container from the dust separator by using a button. The cleaner includes: a main body; a dust separator detachably coupled to the main body configured to separate dust contained in air; a dust container detachably coupled to the dust separator; and a button configured to separate the dust separator from the main body and separate the dust container from the dust separator, when the dust separator is separated from the main body.

A cyclone vacuum cleaner includes two suction fan stages, three stages of separation, plus a HEPA filter and allows capturing of wet or dry material in bag-less or bagged configuration in non-porous paper or plastic bags as well as ordinary garbage bags with pull tie tops for removal, with no suction loss. A steam generator may be added to provide substitute working vacuum fluid to the normal air for dirt pickup. Acoustic sound dumping may also be provided in the architecture of the assembly.

A hand vacuum cleaner has an air flow path extending from a dirty air inlet to a clean air outlet and a suction motor positioned in the air flow path. A cyclone chamber positioned in the air flow path has a cyclone air inlet and a cyclone air outlet. At least one energy storage member is positioned in an energy storage chamber having an energy storage chamber wall. The cyclone air outlet faces the energy storage chamber wall whereby air exiting the cyclone chamber impinges on the energy storage chamber wall.

A surface cleaning apparatus has a first air flow path extending from a dirty air inlet to a clean air outlet with a suction motor and an air treatment member positioned in the first air flow path. A second air flow path extends from an ambient air inlet to a secondary air outlet. An energy storage chamber having at least one energy storage member is positioned in the second air flow path. Ambient air can be drawn through the second air flow path to promote cooling of the energy storage members. A fan unit and or a venture can be used to draw ambient air into the second airflow path.

A device, for trapping an item in an intake hose of a vacuum before the item reaches a collection bin of the vacuum, includes a body and a screen. The body has a chamber, an entrance, and an exit. The chamber is configured such that when the chamber is coupled to an intake hose of a vacuum and the vacuum draws fluid into the intake hose, the fluid flows through the chamber. The entrance is couplable with an intake hose of a vacuum and configured such that when fluid flows through the body's chamber, the fluid enters the chamber through the entrance. The exit is coupleable with the intake hose of a vacuum and configured such that when fluid flows through the body's chamber, the fluid leaves the chamber through the exit. The screen of the device is disposed inside the body's chamber, and sized and configured to allow fluid that the vacuum draws in to flow through the body's chamber while preventing large objects suspended in the fluid from flowing through the body's chamber.

A robot cleaner is provided. The robot cleaner includes a main body, a suction motor provided in the main body to generate a suction force, and a dust collector removably coupled to the main body to collect dust contained in air suctioned by the suction motor. The dust collector includes a first chamber to which the air, which is suctioned into the main body by the suction motor, is introduced, the first chamber including a filter to filter out dust in the suctioned air, and a second chamber arranged side by side with the first chamber, the second chamber including a connection port to which air, which is filtered b the filter in the first chamber, is introduced, and a cyclone dust separator to separate dust from the introduced air.
