Do you want a Dyson, but not the wickedly expensive top model? The V12 Slim doesn't vacuum quite as thoroughly, its dust box is only half the size, and the battery also runs down a little sooner. On the other hand, Dyson's compact class is much lighter and more manoeuvrable. Also on board: the informative display, auto-suction power, laser in the floor nozzle and the strong HEPA filter.
