Abstract

A vacuum assembly having a hand vacuum configuration and a wand vacuum configuration may include a dust cup, a suction motor fluidly coupled to the dust cup, and a power source. The suction motor and the power source may be transitionable between a wand vacuum position and a hand vacuum position. When the suction motor and the power source are in the wand vacuum position, the dust cup, the suction motor, and the power source may be arranged serially. When the suction motor and the power source are in the hand vacuum position, the suction motor and the power source may be arranged in parallel with the dust cup.

First claim

What is claimed is:

1. A vacuum assembly having a hand vacuum configuration and a wand vacuum configuration comprising:
a dust cup;
a suction motor fluidly coupled to the dust cup; and
a power source, the suction motor and the power source being configured to pivot relative to the dust cup such that the suction motor and the power source are transitionable between a wand vacuum position and a hand vacuum position, wherein:
when the suction motor and the power source are in the wand vacuum position, the dust cup, the suction motor, and the power source are arranged along a first axis; and
when the suction motor and the power source are in the hand vacuum position, the suction motor and the power source are arranged along a second axis that is spaced apart from the first axis and generally parallel to the first axis.

2. The vacuum assembly of claim 1 further comprising a body having a first body portion and a second body portion, the second body portion being pivotally coupled to the first body portion, wherein the dust cup is coupled to the first body portion and the suction motor and the power source are coupled to the second body portion.

3. The vacuum assembly of claim 2 , wherein the power source is removably coupled to the second body portion.

4. The vacuum assembly of claim 3 , wherein the power source further comprises a power source release having a graspable actuator configured to cause a power source release lever to pivot in response to being actuated such that the power source release lever disengages a corresponding portion of the second body portion.

5. The vacuum assembly of claim 1 further comprising a flexible suction hose configured to fluidly couple the suction motor to the dust cup.

6. The vacuum assembly of claim 5 , wherein the flexible suction hose extends in response to the power source and the suction motor being transitioned to the hand vacuum position.

7. A surface treatment apparatus comprising:
a surface treatment head;
a wand extending from and coupled to the surface treatment head; and
a vacuum assembly coupled to the wand such that the vacuum assembly is fluidly coupled to the surface treatment head, the vacuum assembly including:
a dust cup;
a suction motor fluidly coupled to the dust cup; and
a power source, the suction motor and the power source being configured to pivot relative to the dust cup such that the suction motor and the power source are transitionable between a wand vacuum position and a hand vacuum position, wherein:
when the suction motor and the power source are in the wand vacuum
position, the dust cup, the suction motor, and the power source are arranged along a first axis; and
when the suction motor and the power source are in the hand vacuum position, the suction motor and the power source are arranged along a second axis that is spaced apart from the first axis and generally parallel to the first axis.

8. The surface treatment apparatus of claim 7 , wherein the wand includes a joint having a first joint body and a second joint body, the first joint body being pivotally coupled to the second joint body.

9. The surface treatment apparatus of claim 8 , wherein the joint is configured to transition between an in-use position and a storage position in response to the pivoting of the first joint body relative to the second joint body.

10. The surface treatment apparatus of claim 9 , wherein when the joint transitions to the storage position, the vacuum assembly moves in a direction towards the surface treatment head.

11. The surface treatment apparatus of claim 7 , wherein the vacuum assembly further comprises a body having a first body portion and a second body portion, the second body portion being pivotally coupled to the first body portion, wherein the dust cup is coupled to the first body portion and the suction motor and the power source are coupled to the second body portion.

12. The surface treatment apparatus of claim 11 , wherein the power source is removably coupled to the second body portion.

13. The surface treatment apparatus of claim 12 , wherein the power source further comprises a power source release having a graspable actuator configured to cause a power source release lever to pivot in response to being actuated such that the power source release lever disengages a corresponding portion of the second body portion.

14. The surface treatment apparatus of claim 11 , wherein the second body portion includes a coupling having a first coupling portion coupled to a second coupling portion.

15. The surface treatment apparatus of claim 14 , wherein the vacuum assembly further comprises a flexible suction hose that extends at least partially between the first coupling portion and the second coupling portion, the flexible suction hose being configured to extend in a direction along the wand in response to the second coupling portion being decoupled from the first coupling portion.

16. The surface treatment apparatus of claim 7 , wherein the vacuum assembly further comprises a flexible suction hose configured to fluidly couple the suction motor to the dust cup.

17. The surface treatment apparatus of claim 16 , wherein the flexible suction hose extends in response to the power source and the suction motor being transitioned to the hand vacuum position.

18. A vacuum assembly of a surface treatment apparatus comprising:
a first body portion, the first body portion being configured to receive a dust cup; and
a second body portion pivotally coupled to the first body portion such that the second body portion is configured to transition between a wand vacuum position and a hand vacuum position, the second body portion being further configured to receive at least one of a suction motor or a power source, wherein:
when in the wand vacuum position, the first body portion and the second body portion are arranged along a first axis; and
when in the hand vacuum position, the second body portion is arranged along a second axis that is spaced apart from the first axis and generally parallel to the first axis.
