Abstract

A vacuum cleaner including a base including a suction nozzle, a handle assembly pivotally coupled to the base, and a dirt collection assembly removably coupled to at least one of the handle assembly or the base. The dirt collection assembly includes a suction motor operable to generate an airflow through the suction nozzle when powered by a power source, and a dirt separator in fluid communication with the suction nozzle operable to separate and collect dirt particles from the airflow drawn through the suction nozzle by the suction motor. The suction motor is unpowerable when the dirt collection assembly is removed from the at least one of the handle assembly or the base.

Claims

1. A vacuum cleaner comprising:

a base including a suction nozzle;

a handle assembly pivotally coupled to the base; and

a dirt collection assembly removably coupled to at least one of the handle assembly or the base, the dirt collection assembly including

a suction motor operable to generate an airflow through the suction nozzle when powered by a power source, and

a dirt separator in fluid communication with the suction nozzle operable to separate and collect dirt particles from the airflow drawn through the suction nozzle by the suction motor;

wherein the suction motor is unpowerable when the dirt collection assembly is removed from the at least one of the handle assembly or the base.

2. The vacuum cleaner of claim 1, wherein the suction motor and the dirt separator are removable together as a unit.

3. The vacuum cleaner of claim 1, wherein the dirt collection assembly includes a handle for removing the dirt collection assembly from the at least one of the handle assembly or the base.

4. The vacuum cleaner of claim 3, wherein the suction motor is disposed generally between the dirt separator and the handle.

5. The vacuum cleaner of claim 1, further comprising a first electrical connector, wherein the dirt collection assembly includes a second electrical connector configured to electrically connect to the first electrical connector to provide power to the motor from the power source.

6. The vacuum cleaner of claim 5, wherein the power source includes a battery disposed on the handle assembly.

7. The vacuum cleaner of claim 1, wherein the suction motor is disposed on top of the dirt separator generally opposite the suction nozzle when the dirt collection assembly is coupled to the at least one of the handle assembly or the base.

8. The vacuum cleaner of claim 7, wherein the dirt collection assembly defines a longitudinal axis, wherein the suction motor includes an output shaft oriented substantially parallel to the longitudinal axis.

9. The vacuum cleaner of claim 7, wherein the dirt collection assembly includes a door for releasing dirt from the dirt separator, the door being positioned at the bottom of the dirt separator generally opposite the suction motor.

10. A vacuum cleaner comprising:

a support assembly;

a suction nozzle; and

a dirt collection assembly removably coupled to the support assembly, the dirt collection assembly including

a suction motor operable to generate an airflow through the suction nozzle when powered by a power source, and

a dirt separator in fluid communication with the suction nozzle operable to separate and collect dirt particles from the airflow drawn through the suction nozzle by the suction motor,

wherein the suction motor is unpowerable when the dirt collection assembly is removed from the support assembly.

11. The vacuum cleaner of claim 10, wherein the support assembly includes a handle assembly and a base.

12. The vacuum cleaner of claim 10, wherein the support assembly includes the body of a canister vacuum.

13. The vacuum cleaner of claim 10, wherein the power source includes a battery coupled to the support assembly, wherein the support assembly includes a first electrical connector electrically coupled to the battery, and wherein the dirt collection assembly includes a second electrical connector electrically coupled to the first electrical connector when the dirt collection assembly is connected to the support assembly establishing an electrical connection between the battery and the suction motor.

14. The vacuum cleaner of claim 13, wherein the second electrical connector is electrically decoupled from the first electrical connector when the dirt collection assembly is removed from the support assembly making the suction motor unpowerable.

15. The vacuum cleaner of claim 10, wherein the dirt collection assembly includes a door for releasing dirt from the dirt separator and a handle for removing the dirt collection assembly from the support assembly, the door being positioned at the bottom of the dirt separator generally opposite the handle.

16. The vacuum cleaner of claim 10, wherein the suction motor and the dirt separator are removable from the support assembly together as a unit.
