It's better to take a cheap Karcher than an expensive crap. Consultants are knowledgeable people, not yap. They said if there are no pets - take VC 2, if there is - VC 3 (easier to clean). Premium is distinguished by a set of nozzles - to each his own. Different pros: Sucks very hard! Consumes little. Easy to clean and almost silent. Stylish. Cons below: The elements of the tube are periodically disconnected (obviously, a consequence of the high suction power).
