Abstract

A multi-operational battery powered vacuum cleaner (1) comprising a hand held vacuum cleaner (1) releasably mounted within a caddy (15) which has a detachable handle (51) and a floor engaging head (19). The hand held unit (1) may be released from the caddy to be used in a first hand held operation. It may alternatively be mounted within the caddy with the handle attached for use as an upright vacuum cleaner in a second operational mode. In a third operational mode the handle (51) may be removed from the caddy while the hand held unit remains mounted in the caddy to provide a compact vacuum cleaner system with a floor engaging head (19). The cleaner further comprises a first spring biased latch member (27) mounted within the caddy (15) to releasably restrain the hand held unit therein A second latch member (53) is mounted within the handle (57) for releasably connecting the handle to the caddy (15).

and

the support caddy comprises at least one recess adapted to receive the at least one caddy-engaging portions of the second spring-biased latch member.

14. The vacuum cleaner system according to claim 12, further comprising a second release member which can be moved relative to the second spring biased latch member to cause the central spring of the second spring-biased latch member to move from its uncompressed to its compressed state.

15. The vacuum cleaner system according to claim 14, wherein the second spring biased latch member comprises a third cam surface which slides relative to a fourth cam surface on the second release member to cause spring of the second spring-biased latch member to move from its uncompressed to its compressed state.

16. The vacuum cleaner system according to claim 15, wherein the second spring-biased latch member comprises a central spring and two end caddy-engaging portions;

and

wherein two third cam surfaces are provided on the second spring-biased latch member, one on each of the two end caddy-engaging portions of the second spring-biased latch member.

17. The vacuum cleaner system according to claim 16 wherein two fourth cam surfaces are provided on the second release member to co-operate with respective ones of the two third cam surfaces on the second spring-biased latch member;

and

wherein each said fourth cam surface is provided as a projecting surface on a back plate which can be moved relative to the second latch member.

18. A battery powered vacuum cleaner system comprising:

a hand held vacuum cleaner comprising an air flow inlet at a first end and a handle at a second end;

a support caddy comprising a support member including a latch member biased by a spring to which the hand held vacuum cleaner can be detachably secured in a nesting fashion;
