- 4. The vacuum cleaner of claim 3 wherein said control assembly comprises a selector switch positioned within a slot in said nozzle base and a slide bar connected to said selector switch, wherein movement of said selector switch to the first and second positions moves said slide bar out of engagement with said finger extending from said door allowing said door to open due to suction air; and wherein movement of said selector switch to said third position moves said slide bar into engagement with said finger to prevent said door from opening due to suction air.
- 5. The vacuum cleaner of claim 1 further comprising a full-size pulley and an idler pulley which are mounted adjacent each other in said nozzle base.
- 6. The vacuum cleaner of claim 5 further comprising a first pulley belt, said first pulley belt engages a drive shaft of said suction source and one of said full-size pulley and idler pulley.
- 7. The vacuum cleaner of claim 6 further comprising a reduction pulley, said reduction pulley being connected to said full-size pulley.
- 8. The vacuum cleaner of claim 7 further comprising a second pulley belt which engages said reduction pulley and a shaft of said brushroll assembly.
- 9. The vacuum cleaner of claim 8 wherein said control assembly further comprises a guide arm assembly connected to said selector switch wherein said guide arm includes a pair of walls forming an opening which selectively receives said first pulley belt, wherein said first pulley belt engages one of said idler pulley and said full-size pulley, wherein movement of said selector switch moves said guide arm and said first pulley belt between alignment with said full-size pulley and said idler pulley.
- 10. A vacuum cleaner comprising:a nozzle base comprising at least one suction opening; a suction source communicating with the primary suction opening; a dust cup assembly releasably secured to said nozzle base, said dust cup assembly defining a dirt and dust collecting chamber, said dust cup assembly comprising: an inlet in fluid communication with at least one suction opening, and a door positioned adjacent said inlet to selectively open and close said inlet, said door comprising a rod extending therefrom and a finger which protrudes from an end of said rod; and a manual control assembly mounted on said nozzle base, said manual control assembly comprising: a selector switch positioned within a slot in said nozzle base, and a slide bar connected to said selector switch, wherein said slide bar, in one position thereof, engages said finger extending from said door to prevent said door from opening due to suction air.
- 11. The vacuum cleaner of claim 10 further comprising a full-size pulley and an idler pulley which are mounted adjacent each other in said nozzle base.
- 12. The vacuum cleaner of claim 11 further comprising a first pulley belt, said first pulley belt engaging one of said full-size pulley and idler pulley.
- 13. The vacuum cleaner of claim 12 wherein said manual control assembly further comprises a guide arm assembly connected to said selector switch, said guide arm assembly including a pair of walls forming an opening which receives said first pulley belt, wherein said first pulley belt engages one of said idler pulley and said full-size pulley.
- 14. The vacuum cleaner of claim 13 further comprising a reduction pulley, said reduction pulley being connected to said full-size pulley, and a second pulley belt which engages said reduction pulley and said shaft of said brushroll assembly.
- 15. The vacuum cleaner of claim 14 wherein when said selector switch is moved to a first position, said slide bar is moved away from said finger of said door thus allowing said door to pivot open when suction air is pulled through said vacuum cleaner, and wherein said guide arm aligns said first pulley belt with said full-size pulley, rotating said brushroll.
- 16. The vacuum cleaner of claim 14 wherein when said selector switch is moved to a second position, said slide bar is moved away from said finger of said door, allowing said door to pivot open due to suction air, and wherein said guide arm is moved to alignment with said idler pulley, thus preventing rotation of said brushroll.
- 17. The vacuum cleaner of claim 14 wherein when said selector switch is moved to a third position, said slide bar is moved into contact with said finger of said door, preventing suction air from entering said inlet of said dust cup, and wherein said guide arm moves into alignment with said idler pulley, thus preventing rotation of said brushroll.
- 18. A vacuum cleaner comprising:a nozzle base comprising a primary suction opening formed therein; a suction source communicating with said primary suction opening; a dust cup assembly releasably positioned in a cavity defined in said nozzle base, said dust cup assembly defining a dirt and dust collecting chamber, said dust cup assembly comprising: an inlet, said inlet being in fluid communication with said primary suction opening, and a door positioned adjacent said inlet to selectively open and close said inlet, said door comprises a rod extending therefrom and a finger which protrudes from an end of said rod; a rotatable brushroll assembly positioned adjacent said primary suction opening, said brushroll including a shaft; at least two pulleys mounted in said nozzle base; a first pulley belt which engages one of said pulleys and a drive shaft of said suction source, a second pulley belt which engages another of said at least two pulleys and said shaft of said brushroll; a manual control assembly mounted on said nozzle base, said manual control assembly comprising: a selector switch positioned within a slot in said nozzle base; a guide arm assembly connected to said selector switch, said guide arm including a pair of walls forming an opening which receives said pulley belt; wherein movement of said selector switch moves said guide arm and said first pulley belt between alignment with one of said at least two pulleys and another of said at least two pulleys.
- 19. The vacuum cleaner of claim 18 wherein said at least two pulleys comprise a full-size pulley and an idler pulley which are mounted adjacent each other in said nozzle base and a reduction pulley connected to said full-size pulley.
- 20. The vacuum cleaner of claim 19 wherein said first pulley belt engages one of said full-size pulley and idler pulley.
- 21. The vacuum cleaner of claim 19 wherein said second pulley belt engages said reduction pulley.
- 22. The vacuum cleaner of claim 18 wherein said manual control assembly further comprises a slide bar connected to said selector switch, wherein said slide bar engages said finger extending from said door to prevent said door from opening due to suction air.
- 23. The vacuum cleaner of claim 22 wherein when said selector switch is moved to a first position, said slide bar is moved away from said finger of said door thus allowing said door to pivot open when suction air is pulled through said vacuum cleaner, and wherein said guide arm aligns said first pulley belt with said full-size pulley, rotating said brushroll.
- 24. The vacuum cleaner of claim 22 wherein when said selector switch is moved to a second position, said slide bar is moved away from said finger of said door, allowing said door to pivot open due to suction air, and wherein said guide arm is moved to alignment with said idler pulley, thus preventing rotation of said brushroll.
- 25. The vacuum cleaner of claim 22 wherein when said selector switch is moved to a third position, said slide bar is moved into contact with said finger of said door, preventing suction air from entering said inlet of said dust cup, and wherein said guide arm moves into alignment with said idler pulley, thus preventing rotation of said brushroll.
