Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.
