Dyson's debut in this category packs the most powerful vacuum built into an autonomous robot to date. It's navigation skills and battery life aren't best in class, but it's cleaning capabilities and jumbo dustbin make up for those weak spots. The one major drawback is the product's height, a limitation imposed by the use of Dyson's patented Cyclone vacuum technology. It's also the most expensive, at $1000. If price isn't a concern and you don't have much low slung furniture, the 360 Eye is the obvious choice.
