Query: After 4 years I did some maintenance

Well... Here's an update.Replaced the agitator and belt.Easy.If you read my former big review I broke the top cord wrap.I ordered a new one. Much better design; only cost a few bucks.Snapped in place; newer ones shouldn't have this problem.2 new belts, 1 agitator, new cord wrap hook, delivered(1 day) 28 bucks.We have burber(sp?) carpet so it knocked out a lot of the bristles and I replaced the belt cause I was there. (lost the extra one that came with vac.)Cleaned out the agitator area LOTS OF DIRT!!!I still think for those of us with less than 5 cats this vacuum works great. I'm really amazed by those who complain it doesn't work or lacks suction. Like I said in my original review for me suction is the smallest issue of all!!!!I've had this vac at least 4 years and besides some minor annoyances it works fine, especially for the money.
