Vacuum cleaners have been around for a while now, and you're probably thinking there aren't any major design or performance breakthroughs left to be achieved. Well, you might be wrong, because Shark has unveiled a new range of vacuums that it claims solve one big problem with today's best vacuum cleaners.
The USP of the Shark PowerDetect vacuum range is that they work just as well going backwards as they do going forwards. Most vacuums are designed to do most of their suction work when you're pushing them, and the return stroke is mostly just to get them back into position for another push.
