Since it is hard to take a photo, I've created this idealized comparison in photoshop, but it pretty much tells the story. Using a vinyl-pool brush style head takes a new technique that takes getting used to (so it doesn't get stuck and not want to move when you are pressing straight down), but the new technique is totally worth it. The fine dust here in the desert gets very "clingy" on my PebbleTec and the roller wheel style head just doesn't cut the mustard, and I have good suction. [Click thumbnail for larger image.]
Anyone else have a similar story?
