Abstract: A compressor has a rotor assembly having an impeller for generating an airflow through the compressor, a stator core assembly for causing rotation of the impeller, and a diffuser assembly for acting on the airflow generated by the impeller. The diffuser assembly has a first diffuser stage and a second diffuser stage. The first and second diffuser stages are separate components connected to one another by a fastener.

Abstract: A motor comprising a frame for supporting a rotor assembly and a stator assembly, the frame comprising an inner wall and an outer wall and a plurality of diffuser vanes extending between the inner wall and outer wall; a rotor assembly comprising a shaft, a magnet, a bearing assembly and an impeller; and a stator assembly comprising a bobbin, a stator core and a winding wound round the bobbin; the impeller comprising a metal hub and an outer portion, the outer portion comprising a plurality of blades and being formed of plastic or carbon fibre composite.

Abstract: A wand assembly for a cleaning appliance includes a handle portion having a channel formed therethrough; a tubular wand received within the channel and moveable between a first position and a second position; a locking mechanism having a lock position and an unlock position and preventing the wand from moving from the first position when in the lock position; and a release mechanism mounted to the wand and which can be actuated to move the locking mechanism from the lock position to the unlock position. The release mechanism is actuated by relative movement of the release mechanism with respect to the wand.

Abstract: A handle assembly for a cleaning appliance includes a handle portion for maneuvering the handle assembly during use, a flexible hose having a first end connectable to a main body of the cleaning appliance and a second end connectable to the handle portion, and a tubular wand. The tubular wand is slidably mounted in the handle portion so as to be moveable between a first position in which the tubular wand extends along the handle portion inside the flexible hose and a second position in which the tubular wand extends beyond the handle portion away from the flexible hose. The handle is releasably attachable to the main body by a catch mechanism arranged so as to release the handle portion from the main body when the tubular wand is moved from the first position to the second position.
