Abstract

A vacuum cleaner comprises: a housing and a motor fan assembly mounted in the housing, the motor fan assembly arranged to generate an air flow. A removable dirt container is mountable on the housing and in fluid communication with a dirty air inlet and the motor fan assembly. A moveable dirt compactor is mounted in the dirt container and moveable between a stowed position and a dirt compacting position wherein the moveable dirt compactor is closer to one end of the dirt container in the dirt compacting position than in the stowed position. Wherein the dirt container comprises a primary handle for actuating the moveable dirt compactor with a first hand and a first auxiliary handle for allowing the user to grip with a second hand.

First claim

The invention claimed is:

1. A vacuum cleaner comprising:
a housing;
a motor fan assembly mounted in the housing, the motor fan assembly arranged to generate an air flow;
a removable dirt container mountable on the housing and in fluid communication with a dirty air inlet and the motor fan assembly;
a dirt separator mounted inside the dirt container;
a moveable dirt compactor mounted in the dirt container and moveable between a first position and a second position; and
wherein the movement of the dirt compactor between the first position and the second position, moves it across substantially the length of the dirt separator; and
wherein the dirt container comprises a primary handle connected to the dirt compactor for actuating the dirt compactor with a first hand and a first auxiliary handle for allowing the user to grip with a second hand, wherein the primary handle is permanently fixed to the dirt compactor so there is no relative movement between the primary handle and the dirt compactor.

2. The vacuum cleaner according to claim 1 , further comprising a battery to power the motor fan assembly, the battery being located in the housing.

3. The vacuum cleaner according to claim 2 , wherein the motor fan assembly is positioned above the dirt container, and the battery is positioned above the motor fan assembly.

4. The vacuum cleaner according to claim 1 , wherein the housing is mounted on a chassis and is removable from the chassis.

5. A vacuum cleaner comprising:
a chassis;
a housing removably mounted on the chassis;
a motor fan assembly mounted in the housing, the motor fan assembly arranged to generate an air flow;
a removable dirt container mountable on the housing and in fluid communication with a dirty air inlet and the motor fan assembly;
a dirt separator mounted inside the dirt container; and
a moveable dirt compactor mounted in the dirt container and moveable between a first position and a second position, and capable of compacting dirt in the dirt separator.

6. The vacuum cleaner of claim 5 , wherein the movement of the dirt compactor between the first position and the second position, moves it across a majority of the length of the dirt separator.

7. The vacuum cleaner of claim 5 , further comprising a battery to power the motor fan assembly, the battery being located in the housing.

8. The vacuum cleaner according to claim 7 , wherein the motor fan assembly is positioned above the dirt container, and the battery is positioned above the motor fan assembly.

9. The vacuum cleaner according to claim 8 , where the dirt separator is located in an air flow path between the dirty air inlet and the motor fan assembly and the dirt separator protrudes through an aperture in the dirt compactor.

10. The vacuum cleaner according to claim 5 , wherein the chassis has a first handle, and the housing has a second handle, the second handle capable of supporting the housing when removed from the chassis, the housing further including a third handle connected to the dirt compactor for moving the dirt compactor from the first position to the second position.
