Abstract

A canister vacuum cleaner that includes a main body to which a hose is attached. The main body includes a chassis, a dirt separator carried by the chassis, and an inlet assembly for carrying fluid from the hose to the dirt separator. The dirt separator includes an inlet located in a base of the dirt separator. The inlet assembly includes a spigot fixed to the chassis and a hose coupling rotatably attached to the spigot. The hose is then attached to the hose coupling, and the spigot projects into the inlet such that the spigot both supports and carries fluid to the dirt separator.

First claim

The invention claimed is:

1. A canister vacuum cleaner comprising a main body to which a hose is attached, the main body comprising a chassis, a dirt separator carried by the chassis, and an inlet assembly for carrying fluid from the hose to the dirt separator, wherein the dirt separator comprises an inlet located in a base of the dirt separator, the inlet assembly comprises a spigot fixed to the chassis and a hose coupling rotatably attached to the spigot, the hose is attached to the hose coupling, and the spigot projects into the inlet such that the spigot both supports and carries fluid to the dirt separator.

2. The vacuum cleaner of claim 1 , wherein the spigot is located at a front of the chassis and extends along an axis about which the hose coupling rotates, and the hose coupling comprises an elbow such that the hose swivels to the left and right as the hose coupling rotates relative to the spigot.

3. The vacuum cleaner of claim 1 , wherein the spigot is located at a front of the chassis and extends along an axis that is tilted relative to vertical when the vacuum cleaner rests on a horizontal surface, the tilt occurring in a direction towards the rear of the chassis.

4. The vacuum cleaner of claim 1 , wherein the end of the hose coupling to which the hose is attached extends along an axis that is inclined upwardly relative to horizontal when the vacuum cleaner rests on a horizontal surface.

5. The vacuum cleaner of claim 1 , wherein the hose is rotatable attached to the hose coupling.

6. The vacuum cleaner of claim 1 , wherein the inlet assembly comprises a barrel-shaped roller attached to the hose coupling.

7. The vacuum cleaner of claim 1 , wherein the spigot supports the base of the dirt separator above the chassis.

8. A canister vacuum cleaner comprising a main body to which a hose is attached, the main body comprising a chassis, a dirt separator carried by the chassis, and an inlet assembly for carrying fluid from the hose to the dirt separator, wherein the dirt separator comprises an inlet located in a base of the dirt separator, the inlet assembly comprises a spigot fixed to the chassis and a hose coupling rotatably attached to the spigot, the spigot projects into the inlet of the dirt separator and extends along an axis about which the hose coupling rotates, the hose is attached to the hose coupling, and the hose coupling comprises an elbow such that the hose swivels to the left and right as the hose coupling rotates relative to the spigot.

9. The vacuum cleaner of claim 8 , wherein the spigot is located at a front of the chassis and extends along an axis that is tilted relative to vertical when the vacuum cleaner rests on a horizontal surface, the tilt occurring in a direction towards the rear of the chassis.

10. The vacuum cleaner of claim 8 , wherein the end of the hose coupling to which the hose is attached extends along an axis that is inclined upwardly relative to horizontal when the vacuum cleaner rests on a horizontal surface.

11. The vacuum cleaner of claim 8 , wherein the hose is rotatable attached to the hose coupling.

12. The vacuum cleaner of claim 8 , wherein the inlet assembly comprises a barrel-shaped roller attached to the hose coupling.

13. The vacuum cleaner of claim 8 , wherein the spigot supports the base of the dirt separator above the chassis.
