Go ahead, take a look. Pretty disgusting, huh?
Now imagine what it would look like if it had been 8 years. That's what I found today. I was trying to vacuum a rug, and was having no success. I changed the (very full) bag, thinking that would fix the problem. I still wasn't getting good sucking power, so something prompted me to flip that puppy over and check out the beater bar.
Ewww. 8 years worth of dirt, dust, hair and other unmentionables. Twenty minutes later, after attacking the vacuum with a screwdriver, utility knife and needle-nose pliers, the vacuum worked again! Hurrah!
So today's house building tip...clean your vacuum!
