Query: Terrible!

First of all, works great for the first couple of weeks, then forget it! The cord is horrendous, doesn't wind well, tangles and knots easily, you can NOT ever get it straight again! The canister does NOT fit tightly. Shoots stuff out the back while vacuuming, so it seems like a never ending process. Hose and attachments are small, the upholstery brush always falls off. I bought a replacement filter hoping that would help, but no.(I cleaned the original one after every usage) I hate dirty floors, and this one is not even good enough for the everyday quick cleaning, I am sorry. Maybe I got a bum vac, but I do not think so.
