Query: It sucks! ... Which is what it's supposed to do.

I've had this vacuum for a little over two years now, and I've been consistently impressed. Very good suction-- if there is any dirt in your carpet or even under it (ever pulled up your carpet?) it will find it. I am amazed at the volume of stuff that shows up in the can and on the filter after each use.Speaking of volume of stuff though... the top filter clogs very fast if things are dirty. In an old apartment, where the carpets weren't too clean when I moved in, I would have to change the filter twice to finish the floors (luckily it comes with two). Filters are easy to clean; just rinse them out (they can go in the dishwasher too).Summary: Works great; super power. Bit of a pain to clean.
