The vacuum, that is. Second time in three months, and the stupid thing is JUST over a year old.
So, after about 20 minutes of deliberation after the second attempt at fixing it failed (no, it's NOT supposed to squeal like that!), I had my coat and shoes on, and was on my way to Target for a replacement.
This time, I spent a little extra and got a vacuum with a four-year warranty, instead of a cheap one with a 90-day warranty (never, EVER buy a vacuum without a good warranty). I vacuumed the main areas of the apartment, sucking up what the old vacuum had missed.
And as a bonus? The one has different scented filters you can buy, so as you vacuum, it makes the air smell good. I immediately installed the apple cinnamon filter, and the house smells nice and sweet.
Sometimes, it's nice to just give up fixing something and buy new.
