I had the same vacuum cleaner for about 18 years. It was a little Hoover Upright Devil and it worked just fine. It didn't have any attachments, though, so the baseboards, drapes and upholstery just continued to develop layer after fine layer of Old Cat Hair.
When it finally sucked its last breath, I bought a very nice Eureka The Boss Smartvac. Except I don't see what's so smart about it. In fact it doesn't seem to be the least bit intelligent. And it has the weird habit of popping the front panel open and projectile shooting it across the room every time I turn off the power. I can only figure that this is to remind me to check? if the bag? is full?
I spend just about as much time fitting the door back and latching the hinge as I do with the actual vacuuming. However, my drapes, baseboards and upholstery are looking spiffier than ever before.
Yesterday, I did a good, thorough cleaning and used every attachment that the Smartvac has to offer. I noticed that I didn't seem to have as much suction as I thought I should have, though. It had an odd sounding noise as well, sort of far-away sounding. After vacuuming the entire living room and bedroom, I noticed that I had left the dial on the hose option rather than the floor option. But I couldn't tell that much difference in the quality of the vacuuming either way. So I think it might just be a dummy dial. Just something to make me think I have a very Smart Vac. If it was so smart, it would have TOLD me in PLAIN ENGLISH that I needed to change the dial back to floor when I was finished with the hose.
I've already picked out my next vacuum. I'm really going to upgrade next time. It may take a while, but my next vacuum cleaner is going to be a MAID.
