A robot floor cleaning system features a mobile floor cleaning robot and an evacuation station. The robot includes: a chassis with at least one drive wheel operable to propel the robot across a floor surface; a cleaning bin disposed within the robot and arranged to receive debris ingested by the robot during cleaning; and a robot vacuum configured to pull debris into the cleaning bin from an opening on an underside of the robot. The evacuation station is configured to evacuate debris from the cleaning bin of the robot, and includes: a housing defining a platform arranged to receive the cleaning robot in a position in which the opening on the underside of the robot aligns with a suction opening defined in the platform; and an evacuation vacuum in fluid communication with the suction opening and operable to draw air into the evacuation station housing through the suction opening.

A suction nozzle includes a nozzle body including a suction port. The suction nozzle also includes a rotary cleaning unit rotatably mounted in the nozzle body and having a cleaning element for cleaning a floor. Additionally, the suction nozzle includes an anti-winder mounted on the nozzle body and having a plurality of contact parts that overlap a side end of the cleaning element along at least a portion of a rotational path followed by the cleaning element of the rotary cleaning unit when the rotary cleaning unit is rotated.

A vacuum cleaner comprises a cleaner main body configured to generate suction power; a suction unit configured to suck up dust and foreign substances by the suction power; a connection pipe configured to transfer the sucked dust and foreign substances; a connection unit comprising a connection pipe accommodator configured to accommodate an end portion of the connection pipe, a separation controller configured to separate the accommodated end portion of the connection pipe from the connection pipe accommodator, and a space configured to place the separation controller therein; and a power cable configured to supply electric power from the cleaner main body to the suction unit, and disposed to pass through the space in which the separation controller of the connection unit is provided.

A clutch device for an upright vacuum cleaner and an upright vacuum cleaner having the same are provided. The clutch device is disposed between an electric motor assembly and a machine body assembly of the upright vacuum cleaner, the electric motor assembly includes an electric motor housing and an electric motor, the machine body assembly includes a machine body and a bridging member rotatably connected to the electric motor housing. The clutch device includes a slide chute; and a triggering member having a first end provided with a sliding column slidaby fitted in the slide chute and a second end provided with a toggling rod configured to stir the electric motor to move. When the bridging member drives the slide chute to move, the sliding column slides along the slide chute to rotate the triggering member. When the triggering member rotates, the toggling rod stirs the electric motor to rotate.

A charging stand (100) for a vacuum cleaner (200) includes: a body (1); and a pedal (2) disposed on the body (1) and pivotable between a first position and a second position, wherein when the pedal (2) is in the first position, the vacuum cleaner (200) is suitable to be placed on the pedal (2) to be charged.

A cleaner head for a vacuum cleaner includes a body that defines a suction chamber, the suction chamber having a suction inlet for engaging a surface to be cleaned, and an outlet for fluid connection to a suction generator of a vacuum cleaner. The cleaner head further includes first and second brush bars each configured to contact a surface engaged by the suction inlet, and a drive mechanism which has an actuator. The drive mechanism is configured to rotate the brush bars about respective axes. The drive mechanism is also configured to rotate the first brush bar independently of the second brush bar, and to rotate the second brush bar independently of the first brush bar.

A vacuum system for vacuuming is disclosed. The vacuum system includes a baseboard cleaning attachment, a floor cleaning attachment, and a hose attachment. Each of the attachments is selectively mounted to a hose of the vacuum system for vacuuming floors, baseboards and tight spaces. The baseboard cleaning attachment includes a brush head having a right-angled portion, and a curved portion. The brush head includes a neck to mount the brush head to the hose. The right-angled portion is aligned with the baseboard and is used to vacuum. The floor cleaning attachment includes an elongated tube, and an under furniture handle mounted to the elongated tube. The elongated tube includes a beater head with a beater. The elongated tube is mounted to the hose, and the under furniture handle is used vacuum under furniture. The hose attachment is in an S-shape for tight spaces.

A battery pack, power tool, and power tool combination. The battery pack includes one or more battery cells, a first terminal electrically connected to the one or more battery cells, a high current power supply terminal, a power switch electrically connected between the one or more battery cells and the high current power supply terminal, and a low current power supply terminal electrically connected to the one or more battery cells. The first terminal and low current power supply terminal are operable to provide a substantially continuous low current to the power tool during a normal operating state of the battery pack. The battery pack also includes a controller operable to control the power switch to provide high current power through the high current power supply terminal in response to a call for power from the power tool.

A suction nozzle apparatus and a cleaner having the same includes a casing of which a mounting groove is formed in a bottom surface, a drum brush rotatably coupled to the mounting groove of the casing, and a cutting member configured to remove a foreign substance wound around the drum brush. The drum brush includes a drum core in which at least one foreign substance collecting groove that the foreign substance is wound is formed in an outer circumference and a blade formed in a spiral form in the outer circumference of the drum core.

A cleaning roller mountable to a cleaning robot is featured. The cleaning roller includes an elongate member extending along a longitudinal axis of the cleaning roller, and a vane extending outward from the elongate member. The vane includes a first vane portion attached to the elongate member, and a second vane portion attached to the first vane portion. The first vane portion extends from the elongate member at a location intersecting a radial axis of the cleaning roller. The first vane portion extends along a first axis angled relative to the radial axis and away from the radial axis in a tangential direction. The second vane portion extends along a second axis angled relative to the first axis. A first angle between the first axis and the radial axis is greater than a second angle between the second axis and the radial axis.
