I have two.
My first "worst experience" was with a Regina Housekeeper Whispurr. This vacuum was a tank, and not in a good way. It was heavy and clunky, and NEVER cleaned well. The only positive thing about this machine was that it had quite a bit of hose suction. But this vacuum taught me that just because a machine sucks at the hose, it can BLOW with cleaning at the brushroll. It would frequently grind dirt in, and make the carpet appear dingy and worn.
My other one was caused by my own stupidity (and is quite hilarious taken in context). I was vacuuming out my wood pellet stove with a 6 gal shop vac. About 5 minutes in, I heard a thud inside the cleaner. I didn't turn around, and kept on going. Turns out the filter came off, and I had a tornado of black soot blowing around the living room. Yup... I vacuumed the ENTIRE stove before I smelled the soot. It made one hell of a mess
