4X SUCTION POWER? HARDLY! I used to have 3 Black + Deckers and this vacuum is no different than the one I bought a year ago. This statement was decisive for the purchase. Unfortunately it's only 30 days old so I can't return it. Works well with good suction but that's not what they claim. I think they made a mistake by not having a fold out brush. The brush is scratch-resistant on wooden floors and when used on the stovetop and in the oven. Also, the extension is long but the hole is much smaller and the slightest touch on the ground will collapse the extension fairly easily. Very annoying to keep stopping and renewing it. Love the new filter, it's a lot easier to clean and snaps in so quickly. I hate to complain, but that's the way it is.
