Summary: We've gone through numerous vacuums and all seem to have some type of downside. The Hoover Platinum UH30010COM seems to have the best blend of features and value that we have experienced. The two vacuum design (one standup and one portable) is a great convenience and optimization of features. This allows the upright to be very light (at 11 lbs it is almost 50% lighter than most uprights). The portable is very convenient for tight spaces and especially the stairs.
Summary: Shopped for a while for a vacuum and this beats all unless you want to spend around $500. Only down thing I see is there's no controlling the height for the carpet. Must be self-adjusting while I do prefer to control this, especially on longer nap, but not a problem.
