I've had only one husband but I've owned 4 vacuums in my life.
#1 The oldest vacuum is a 50' or 60's canister, which belonged to my great uncle. It follows you around like a little aqua space ship from the Jetsons. Although I don't actually use it (my mother did), I keep it for the kitch value.
#2 was the old workhorse, a Singer. Who knew Singer made vacuums? I didn't until I worked for Singer one summer during college. And how many college students buy a vacuum? Well, I had a nasty shag rug to keep clean and I got an employee discount. It lasted over 20 years before it started making funny noises. It was hard to find bags for it. I usually had to drive 20-30 miles to the nearest Mart-type store to find them.
#3 Tired of searching for bags, and cutting bags open to retrieve the sucked up Lego pieces, I decided to get a bagless vac. With a choice of 2 at Costco, I got the Eureka. Eh. Meh. I have been able to find all the Lego pieces before I empty the canister. But it is SO heavy and the suction isn't great and now it is making funny noises too. So like a desperate housewife I always had my eye out for something else...
#4: I've been dreaming of the Dyson Ball for a while. But the price! I think it was $599 the last time I was at BB&B. Then I found woot.com. They sell one thing a day. The first day it was a camera. What the heck, I thought, I'll just check it out tomorrow to see what they have. On the second day there it was, my Dyson, my Dream. For less than half the price (refurbished, but who cares). It arrived yesterday.
Folks, I must shout it out to the world: "I'm in love with Dyson." Boy can it suck! And dumps out so easily and cleanly. Ernest put it together for me and vacuumed the living room twice before I even got my hands on it! It drives like a Ferrari. Oops, in this household it drives like a Lotus.
