The best budget robot vacuums you can buy

Our overall favorite affordable robot vacuum is the Anker RoboVac 10. This model retails for only 199, it gets positive user reviews, and it did exceptionally well in our tests. In fact, it outperformed the popular iRobot Roomba 770 and 880, and was only barely beat by models from Dyson and Samsung that cost up to five times as much. We estimate it will clean over 80 grams of dirt a week--about as much as a traditional vacuum can hold. A full clean of our test track took two hours, but you can schedule the vacuum to clean when you're not home.
