What is claimed: 1. A floor care apparatus, comprising: a housing including a first section and a second section; a suction inlet carried on said first section; a suction generator carried on said housing; a dirt collection vessel carried on said housing; a telescoping handle stalk and control handle received in a well carried on said second section; and a handle adjustment mechanism including a control switch, an adjustment block, a linkage connecting said control switch with said adjustment block and a locking pin securing said handle stalk in a selected position in said well. 2. The apparatus of claim 1, further including a series of spaced apertures in a wall of said second section defining at least a portion of said well. 3. The apparatus of claim 2, further including a spring biasing said locking pin into one of said spaced apertures so as to lock said handle stalk in a selected position in said well. 4. The apparatus of claim 3, wherein said adjustment block includes a first cam surface, said locking pin includes a second cam surface and said first cam surface engages said second cam surface. 5. The apparatus of claim 4, wherein said control switch is displaceable between a first position wherein said locking pin is biased by said spring into one of said spaced apertures locking said handle stalk in a selected position in said well and a second position wherein said adjustment block is shifted to displace said locking pin against a biasing force of said spring and release said locking pin from said spaced aperture and thereby allow said handle stalk to be repositioned in said well in order to adjust length of said control handle. 6. The apparatus of claim 5, wherein said linkage is an elongated rod and said control switch is positioned on said control handle at a proximal end of said handle stalk remote from said locking pin. 7. The apparatus of claim 6, wherein said handle stalk includes a lumen and said linkage extends through said lumen between said control switch and said adjustment block. 8. The apparatus of claim 7, wherein said adjustment block is forked and includes an elongated slot. 9. The apparatus of claim 8, wherein said locking pin passes through said elongated slot in said forked adjustment block. 10. The apparatus of claim 9, wherein said locking pin includes a head having a cavity and an end of said spring is received in said cavity. 11. The apparatus of claim 10, wherein said second cam surface is provided on said head. 12. The apparatus of claim 1, wherein said dirt collection vessel is a dirt cup. 13. The apparatus of claim 1, wherein said dirt cup includes a cylindrical sidewall, a tangentially directed inlet and an axially directed outlet. 14. The apparatus of claim 13, further including a filter in said dirt cup. 15. The apparatus of claim 1, wherein said first section is pivotally connected to said second section. 16. A telescoping handle assembly for a floor care appliance, comprising, a telescoping handle stalk and control handle received in a well carried on a housing of the floor care apparatus; and a handle adjustment mechanism including a control switch, an adjustment block, a linkage connecting said control switch with said adjustment block and a locking pin securing said handle stalk in a selected position in a said well.
