A vacuum cleaner doesn't have to be robotic for us to review it. In this case, the Gtech AirRam caught our eye with its activity-tracking, USB-equipped rechargeable battery that lets you see how much electricity you're using or calories you're burning. Those features aren't quite enough to sell us on the $349.95 (direct) upright vacuum alone, but its admirable combination of power and portability make it appealing if you have the cash. It's light and cordless, and can still pick up a good amount of dust and dirt from the carpet.

Design

The AirRam is very slight for an upright vacuum cleaner. It doesn't have a bag or a canister, instead collecting everything it sucks up in a compartment on its main body. The neck of the vacuum consists only of the battery compartment, the power switch above the battery compartment, a small carrying handle, and a larger, comfortable handle on top for holding while using the AirRam. The whole device weighs just 7.7 pounds, making it very easy to carry anywhere. And since it's bagless and has a low, 3.8-inch profile, it can easily get under crevasses.

The neck connects to the body of the vacuum at a large silver-colored bar that tilts back when you pull it with your foot. It might seem strange compared to the more conventional levers and pedals on other upright vacuums that let them tilt, but it's easier to use. When the vacuum tilts and is running, the joint between the neck and the body pivot, letting you steer and turn in much tighter corners than more conventional vacuums.
