A cyclonic separator comprising a cyclone chamber defined between an outer wall and a shroud. The shroud comprises an inlet opening through which fluid enters the cyclone chamber, and a plurality of perforations through which fluid exits the cyclone chamber. Fluid within the cyclone chamber is then free to spiral about the shroud and over the inlet opening.

Cyclonic separator

A docking station for a mobile robot including a first side portion and a second side portion and housing an electrical system having power input means. The power input means includes a first power input socket provided on the first side portion and a second power input socket provided on the second side portion. The two power input sockets allows a user flexibility in their choice of location for the docking station in an environment.

Docking station for a mobile robot

A docking station for a mobile robot comprising a base portion that is locatable on a floor surface and a rear portion that is pivotable with respect to the base portion, thereby permitting a user to place the docking station on the floor in an unfolded configuration but to store the docking station in a folded configuration.

A robotic system comprising a mobile robot including a body housing a rechargeable power source and first electrical contact means disposed on the body and a docking station including second electrical contact means, wherein the mobile robot is dockable on the docking station in order to charge the rechargeable power source. The first electrical contact means includes at least one electrical contact aligned on a first contact axis and the second electrical contact means includes at least one elongate contact, wherein when the robot is docked on the docking station such that electrical contact is established between the first electrical contact means and the electrical contact means. The at least one elongate contact extends in a direction that is transverse to the first contact axis which permits electrical contact to be established between the robot and the docking station while accommodating a degree of lateral and angular misalignment therebetween.

A cyclonic separator comprising a first cyclone stage, a second cyclone stage, an inlet duct, and an outlet duct. The first cyclone stage comprises a first dirt collection chamber. The second cyclone stage is located downstream of the first cyclone stage and comprises a second dirt collection chamber. The inlet duct carries fluid to the first cyclone stage, and the outlet duct carries fluid from the second cyclone stage. The first dirt collection chamber then surrounds at least partly the inlet duct and the outlet duct.

Charging unit

A cyclonic separator comprising a first cyclone stage, a second cyclone stage and an inlet duct. The first cyclone stage comprises a cyclone chamber and a first dirt collection chamber. The second cyclone stage is located downstream of the first cyclone stage and comprises a second dirt collection chamber. The inlet duct carries fluid from an opening in the base of the cyclonic separator to the cyclone chamber, and the first dirt collection chamber surrounds at least partly the inlet duct and the second dirt collection chamber.

Charging apparatus

Charger for an electric device

An attachment for a vacuum cleaning appliance includes a head and a handle connected to the head. The head includes a bristle carrier having a plurality of bristles, and a bristle cover having a plurality of apertures. A conduit is connectable to a vacuum cleaning appliance for conveying an air flow towards the appliance. The head includes a first suction opening of the conduit and the handle includes a second suction opening of the conduit. An actuator effects relative movement between the bristle carrier and the bristle cover from a stowed configuration in which the bristles are retracted relative to the bristle cover to a deployed configuration in which the bristles protrude from the bristle cover through the apertures.

Attachment for a vacuum cleaning appliance

An attachment for a vacuum cleaning appliance includes a head and a handle connected to the head. The head includes a bristle carrier having a plurality of bristles, and a bristle cover having a plurality of apertures. A conduit is connectable to a vacuum cleaning appliance for conveying an air flow from the bristle cover towards the appliance. The head includes a suction opening of the conduit and the handle includes an air bleed into the conduit. An actuator effects relative movement between the bristle carrier and the bristle cover from a stowed configuration in which the bristles are retracted relative to the bristle cover to a deployed configuration in which the bristles protrude from the bristle cover through the apertures. A mechanism is provided for controlling the air flow through the air bleed, for example depending on the configuration of the bristle carrier and the bristle cover so that when the head is in its deployed configuration there is a relatively low air flow into the suction opening to prevent the head from being pushed down against, for example, the skin of the pet being groomed, whereas when the head is in its stowed configuration it is preferable to have a relatively high air flow into the suction opening in order to draw the hair collected between the bristles into the conduit.

A grooming device includes a head and a handle. A first end of the handle is connected to the head, and a second end of the handle is connectable to a vacuum cleaning appliance. The head includes a bristle carrier having a plurality of bristles, and a bristle cover having a plurality of apertures. The device includes an actuator manually operable by a user to effect relative movement between the bristle carrier and the bristle cover from a stowed configuration in which the bristles are retracted relative to the bristle cover to a deployed configuration in which the bristles protrude from the bristle cover through the apertures. The handle includes a conduit for conveying an air flow from the head to the second end of the handle. Resilient members are provided for returning the head to the stowed configuration automatically when the actuator is released by the user. In addition to enabling hair or other matter collected between the bristles of the bristle carrier to be readily dislodged from the device, the automatic retraction of the bristles can ensure that the bristles are not exposed when the device is not in use.
