I like the FQ b/c, like the rainbow, I get to see what was picked up when I empty it or just lift off the motor to peer in. Filtering quality is quite good, I serviced mine completely when I bought it...used it a good amount, and the filters are so clean afterwards. I'm with Dysonman1, like having all the tools right there when you want them since they are on the machine itself....like the two speed motors too
