Abstract

A vacuum cleaner apparatus for securing a hand held vacuum cleaner having a housing, the housing comprising a motor-fan unit, a dust container, and an air passage. The vacuum cleaner apparatus has a shaft part to which the housing can be secured, the shaft part comprising a handle and one or more batteries. The vacuum cleaner apparatus also has a floor nozzle and a tube passage configured to connect the floor nozzle to the air passage when the housing is secured to the shaft part.

Claims

1. A vacuum cleaner apparatus for operatively securing a hand held vacuum cleaner (11) having a housing (20) comprising a motor-fan unit (22), a dust container (31), and an air passage (27), the vacuum cleaner apparatus comprising:

a shaft part (10) to which the housing can be removably secured, the shaft part comprising a handle (16) and one or more batteries (18);

a floor nozzle (12); and

a tube passage (15) configured to connect the floor nozzle to the air passage when the housing is secured to the shaft part.

2. The vacuum cleaner apparatus according to claim 1, wherein the shaft part (10) further comprises an electric circuit operably connected to said one or more batteries (18).

3. The vacuum cleaner apparatus according to claim 2, wherein at least a part of the electric circuit is operably connected to the hand held vacuum cleaner (11) via a connection (25) when the housing (20) is secured to the shaft part (10).

4. The vacuum cleaner apparatus according to claim 3, wherein the shaft part (10) further comprises an operating knob (17) that is operably connected to the hand held vacuum cleaner (11) via at least a part of the electric circuit when the housing (20) is secured to the shaft part.

5. The vacuum cleaner apparatus according to claim 1, wherein the shaft part (10) further comprises an electrical charger connection to charge the one or more batteries (18).

6. The vacuum cleaner apparatus according to claim 1, wherein the floor nozzle (12) comprises an electrically driven bush roll (13).

7. The vacuum cleaner apparatus according to claim 6, wherein the electrically driven bush roll (13) is driven by an electric motor, said motor receiving energy from the one or more batteries (18).

8. The vacuum cleaner apparatus according to claim 1, wherein the motor-fan unit (22), when activated, is supplied with energy by means of the one or more batteries (18) when the housing (20) is secured to the shaft part (10).
