The best affordable robot vacuums of 2018

If you make a purchase by clicking one of our links, we may earn a small share of the revenue. However, our picks and opinions are independent from USA Today's newsroom and any business incentives. Though high-end robotic cleaners can cost close to $1,000, our tests show that a host of less-expensive--and sometimes lesser-known--models will clean your house nearly as well as pricier robot vacs. No robot vacuum will clean as well as a traditional canister or upright, but they can keep floors looking fresh between cleanings without the cost of something like the Dyson 360 Eye. To find the best that won't break the bank, we rounded up the most popular robot vacuums that retail for less than $400 and spent a few weeks putting them through our robot vacuum obstacle course.
