buy silver heels Hoover WindTunnel Bagless Upright UH70105
bought this in june 2010 and have used it continuously since then.
excellent product design. easy to assemble. convenient handles, top and mid, and on/off switch near handle. easy foot peddle control of vertical stack. dumping the cylinder much easier and cleaner than loading and unloading a traditional bag. only two easily accessible filters to deal with. very clever red/green vacuum level indicator.
amazing suction. a good thing. brush tool works great for surface cleaning. floor intake really pulls the stuff off of and out of rugs. but you almost have to be careful when using the hand tools. haven't tried the spinning brush tool yet.
also steers straight. other vacuums can steer off to one side.
very quiet compared to most other vacuums i've owned or used elsewhere.
would be good if the hose and extension tube were longer. and the flimsy shipping box arrived partially open. oh well.
overall great product and well worth the ~$100 price.
