Sure have...
The Riccar does very well, well over 70" of lift. The Dyson was quite a surprise though.
Riccar 8850 from base (10% full HEPA) = 75" lift
Riccar 8850 from base (w/out filters or bag) = 76" lift
Riccar 8850 from hose (10% full HEPA) = 72" lift
Riccar 8850 from hose (w/out filters or bag) = 74" lift
