Vacuum Cleaners Discussions

Is NOT worth the $ cuz it is a terrible cleaner; nowhere near the power of older Kirbys.  I saw a demo of the Sentria & it didn't touch any dirt from the carpets; couldn't even pick up anything.  Then I went over the same area with my Classic Omega & the 30+ yr old Kirby pulled out MILLENIUMS of dirt even thru the floorboard.  Why is the Sentria only 1/1000 as powerful as the pre-G Series Kirbys?  I don't think trading an old Kirby is worth anything; I think customers are fooled when they trade their older, more powerful Kirby for the worthless Sentria.  I've owned that Omega & no dirt can hide from a 30+ yr old Kirby!
