Query: Piece of junk

I purchased mine at Wal-Mart and it is hands-down the WORST vacuum I have ever used. I cannot wait until I can afford to replace it and send it to the dump, where it belongs. The "bagless" system is a complete joke. Debris gets nicely jammed up into the little nooks and crannies (where it must be pulled out by hand). Rather than landing in the removable cup, hair and dirt are shoved up into the top piece. The aforementioned cleaning (read: pulling) out of hair, dust and dirt makes a lovely mess. Then there's is the so-called "power force". The sucking "power" has declined to the point where I'm better off taking a broom to the carpet. I'll go over and over the same spot before debris is picked up, only to have said debris dumped when I move onto the next area. Vacuuming has turned into such an aggravating task, I strongly recommend going with ANY other vacuum. I will never purchase another Bissell vacuum and will avoid the bagless varieties like the plague.
