Vacuum cleaner

1. A vacuum cleaner, comprising:

a base housing having a front and an underside, and having a suction nozzle comprising a front suction nozzle opening provided on the front of the base housing;

a suction source in fluid communication with the suction nozzle for generating a working airstream through the vacuum cleaner; and

a diverter assembly to selectively restrict a portion of the front suction nozzle opening, comprising:

a diverter member at the front suction nozzle opening and moveable between an unrestricted position in which the front suction nozzle opening is unrestricted and a restricted position in which the front suction nozzle opening is partially restricted; and

an actuator operably coupled with the diverter member for movement of the diverter member between the unrestricted and restricted positions;

wherein the diverter member is vertically moveable relative to the front suction nozzle opening and has a bottom edge which is lowered in the restricted position and which is raised and spaced from a surface to be cleaned in the unrestricted position; and

wherein the diverter assembly further comprises a spring biasing the diverter member to the unrestricted position.

2. The vacuum cleaner of claim 1 , wherein the diverter member is provided on the front of the base housing.

3. The vacuum cleaner of claim 2 , wherein the base housing includes opposing side walls joined with the front, and wherein the diverter member extends along the front between the side walls.

4. The vacuum cleaner of claim 1 , wherein the suction nozzle further comprises an underside suction nozzle opening provided on the underside of the base housing, wherein the underside suction nozzle opening remains unrestricted when the diverter member is in the restricted position.

5. The vacuum cleaner of claim 1 , wherein at least a portion of the bottom edge is in contact with the surface to be cleaned in the restricted position.

6. The vacuum cleaner of claim 5 , wherein an outer end portion of the bottom edge is spaced from the surface to be cleaned in the restricted position.

7. The vacuum cleaner of claim 1 , wherein the bottom edge comprises end portions that are vertically spaced with respect to a middle portion of the bottom edge.

8. The vacuum cleaner of claim 1 , wherein the actuator comprises a solenoid piston, wherein a portion of the solenoid piston selectively engages a portion of the diverter member to move the diverter member to the restricted position.

9. The vacuum cleaner of claim 1 , wherein the diverter member further comprises a pair of pivoting members pivotally mounted to the base housing.

10. The vacuum cleaner of claim 9 , wherein the actuator is configured to selectively engage at least one of the pivoting members to move the diverter member to the restricted position.

11. The vacuum cleaner of claim 1 , wherein the diverter assembly further comprises an edge illuminator carried by the base housing and configured to emit light when the diverter member is in the restricted position.

12. The vacuum cleaner of claim 1 , and further comprising an upper unit pivotally coupled to the base housing and having handle, wherein the diverter assembly further comprises a button provided on the handle and an electrical switch to selectively energize the actuator operatively coupled to the button.

13. A vacuum cleaner, comprising:

a base housing having a front and an underside, and having a suction nozzle comprising a front suction nozzle opening provided on the front of the base housing;

an agitator within the base housing and provided rearwardly of the front of the base housing and rearwardly of the front suction nozzle opening;

a suction source in fluid communication with the suction nozzle for generating a working airstream through the vacuum cleaner; and

a diverter assembly to selectively restrict a portion of the front suction nozzle opening, comprising:

a diverter member on the front of the base housing and moveable between an unrestricted position in which the front suction nozzle opening is unrestricted and a restricted position in which the front suction nozzle opening is partially restricted; and

an actuator operably coupled with the diverter member for movement of the diverter member between the unrestricted and restricted positions;

wherein the diverter member comprises a bottom edge, and wherein the bottom edge comprises end portions that are elevated upward with respect to a middle portion of the bottom edge.

14. The vacuum cleaner of claim 13 , wherein the suction nozzle further comprises an underside suction nozzle opening provided on the underside of the base housing, wherein the underside suction nozzle opening remains unrestricted when the diverter member is in the restricted position.

15. The vacuum cleaner of claim 13 , wherein the actuator comprises a solenoid piston, wherein a portion of the solenoid piston selectively engages a portion of the diverter member to move the diverter member to the restricted position.

16. The vacuum cleaner of claim 13 , wherein the diverter assembly further comprises an edge illuminator carried by the base housing and configured to emit light when the diverter member is in the restricted position.

17. A vacuum cleaner, comprising:

a base housing having a front and an underside;

a suction nozzle at least partially disposed on the underside and on the front of the base housing and comprising a front suction nozzle opening formed in the front of the base housing;

a suction source in fluid communication with the suction nozzle for generating a working airstream through the vacuum cleaner;

a duct fluidly communicating the suction nozzle with the suction source and having an inlet end provided in the base housing; and

a diverter assembly to selectively restrict a portion of the front suction nozzle opening, comprising:

a diverter member extending along the front of the base housing at the front suction nozzle opening and moveable between an unrestricted position in which the front suction nozzle opening is unrestricted and a restricted position in which the front suction nozzle opening is partially restricted; and

an actuator operably coupled with the diverter member for movement of the diverter member between the unrestricted and restricted positions;

wherein the diverter member is vertically moveable relative to the front suction nozzle opening and has a bottom edge which is lowered in the restricted position and which is raised and spaced from a surface to be cleaned in the unrestricted position; and

wherein the bottom edge comprises end portions that are elevated upward with respect to a middle portion of the bottom edge.
