Title: One of the least overlooked parts on a vacuum.
Review: If you have a vacuum cleaner that doesn't seem to be working as it used to, try flipping it over, clean the clumps of hair that are wrapped around the beater bar, and replace the drive belt. Unless your vacuum has some other internal mechanical problem, this will almost always make the vacuum run like new.The drive belt on our Bissell was still intact, but had slackened enough to slip when in use. I purchased a new drive belt, and when I installed it, I also eliminated a salon's worth of hair from around the beater bar. That, and cleaning the miscellaneous filters on the vacuum all made for a noticeable increase in power. Now our Bissell sucks...in a good way.
