This vacuum was expensive, but completely worth it. I LOVE this machine. Its suction is much more powerful than my previous panasonic. It's easy to use -- even cleaning the filter is simple. I selected this machine because I figured that over time the lifetime filter would save me money and be convenient. I have not been disappointed.My one (very small) complaint has to do with the extension handle/ hose. It takes a few steps to attach the hose the correct way to use. This really is me just being lazy... more than a real problem.The one actual problem I had with this product was that the carpet roller sometimes catches. I called the help line and the representative told me how to fix this (lay the vacuum down and switch the handle back and forth several times). I fix it when it happens on occasion and I continue on.No real complaints. This is a great product.
