Dyson
Truth is, no robot vacuum will clean as well as a traditional canister or upright. But they can keep floors looking fresh between cleanings. The Reviewed team spent a few weeks putting models through their robot vacuum obstacle course. While they did uncover a few robots to avoid at any cost, it turns out that the best low-cost vacuums can stand sensor-to-sensor with their high-end cousins. (Smell ya later, $1,000 Dyson.)
