Panasonic's hybrid MC-HS700G is a full-sized vacuum cleaner that's strong enough to lift a bowling ball, but it can be charged from a USB port giving you up to 20-minutes of suction without a tether to a wall outlet.

You'll want to keep the MC-HS700G plugged into an AC outlet to take full advantage of its dust sensor, cyclone-action suction and built-in headlights for spotting dirty areas on your floor. But if you're cleaning your car or other areas in your home that doesn't have a nearby outlet, the vacuum's rechargeable battery boasts up to 20-minutes of cleaning on a single charge.

However, battery life dwindles to a mere six minutes at full power. And the vacuum is a hefty $700, making it more expensive than even Dyson's high-end models. But looking over at the tangle of cables on the floor, a rechargeable vacuum that can outperform a dustbuster and share our smartphone's charger is still quite tempting.
