The nozzle is also configured to perform as a robotic vacuum cleaner when detached from the vacuum cleaner.

An all in the head surface cleaning apparatus includes a surface cleaning head and an upper portion that is moveably mounted to the surface cleaning head between a storage position and a floor cleaning position. The upper portion comprises a drive handle. A portable cleaning unit comprising an air treatment member and a suction motor is removably mounted in the surface cleaning head.

A surface cleaning apparatus comprises a base, a portable cleaning unit removably mounted to the base and comprising at least one air treatment member, a portable cleaning unit energy storage member and a portable cleaning unit suction motor. The portable cleaning unit suction motor is operable on power provided by the portable cleaning unit energy storage member when the portable cleaning unit is removed from the base. The surface cleaning apparatus comprises or is connectable to a power cord. When the portable cleaning unit is mounted to the base and when the surface cleaning apparatus is connected to an external source of power by the power cord, the portable cleaning unit energy storage member is chargeable on power provided by the power cord provided by the external source of power and the portable cleaning unit suction motor is concurrently operable on power provided by the power cord provided by the external source of power.

A hand vacuum cleaner has an information display device provided on a rear wall of the rear end of the hand vacuum cleaner.

A surface cleaning apparatus includes a floor cleaning unit and a portable surface cleaning unit. The floor cleaning unit includes a surface cleaning head, an upper section moveably mounted to the surface cleaning head between an upright storage position and a rearwardly inclined floor cleaning position, a charger having an energy storage member, and an air flow path extending from the dirty air inlet to a floor cleaning unit air outlet. The portable surface cleaning unit is connectable to the floor cleaning unit, and includes a portable surface cleaning unit air inlet connectable in air flow communication with the floor cleaning unit air outlet, a main body, an air treatment member, a suction motor, a handle and a capacitor. When fully charged, the energy storage member stores sufficient stored power to recharge the capacitor at least twice.

A vacuum cleaner has a portable cleaning unit that is removably mounted to the surface cleaning head. The vacuum cleaner is operable in a floor cleaning configuration in which the portable cleaning unit is mounted to the surface cleaning head and is part of the air flow path through the vacuum cleaner. The portable cleaning unit is also useable in a portable cleaning configuration in which the portable cleaning unit is removed from the surface cleaning head.

A surface cleaning apparatus or a docking station for a surface cleaning apparatus comprises a housing body has air flow path extending from an air inlet of the housing body to an air outlet of the housing body and, a non-cyclonic momentum separator positioned in the housing body wherein a portion of the momentum separator is spaced from the housing body wherein a chamber is provided exterior to the momentum separator and within the housing body. An air flow conduit extends from the air inlet of the housing body to an air inlet of the momentum separator, and the air flow conduit extends through the chamber. A portion of the momentum separator that is spaced from the housing body comprises at least two sides of the momentum separator, and the at least two sides of the momentum separator are porous and comprise an air outlet of the momentum separator.

An air treatment apparatus has a momentum separator positioned in an air flow path. The momentum separator has an upper wall, a lower wall, a sidewall extending between the upper and lower walls and a momentum separator air inlet. The upper wall comprises an upper screen and an upper end wall is spaced from and faces the upper screen wherein an upper air flow chamber is positioned between the upper end wall and the upper screen.

A docking station for a robotic surface cleaning apparatus has a momentum separator. The momentum separator has a plurality of walls comprising an upper wall, a lower wall and a first sidewall, wherein the first sidewall extends between the upper and lower walls, and wherein the first sidewall comprises a side screen. A first end wall is spaced from and faces the side screen wherein an up flow chamber is positioned between the first end wall and the side screen.
