It's easy to tell when hardwood floors are clean, but it's not so obvious when it comes to carpets. Who knows how much dust, dirt and debris are hidden amongst those fibres? So instead of randomly running a vacuum over every inch of your living room, hoping it's clean, Samsung's new Motion Sync vac tells with an impossible to misunderstand red light/green light approach.
Using the company's tried-and-true dust sensing technology that monitors the amount of particles being drawn into the vacuum's storage chamber, the Motion Sync — or SC20F70 if you want to get technical — reports back the conditions under foot. If the area of the floor you're working on is clean, you get a green light. If it needs a few more passes, you see red — pretty straightforward.
The vacuum's canister also benefits from a set of oversized wheels angled in at the top to prevent it from rolling over at every corner in your home. That alone could be worth the vacuum's $US800 price tag, but a feature that guarantees you don't have to do housework a minute longer than necessary? That's priceless. [Samsung via Fareastgizmos]
