Under three hundred dollars you can get, in 2026, a robot with laser navigation, a map of your home and enough suction for hard floors and low-pile carpet. Some come with a self-emptying station, often as the "plus" version of the same robot. What you usually miss: a station that washes the mop, a camera that recognizes socks and cables, and brushes that reach into the corners.
The list below changes daily: a model that drops just under the limit today because of an offer may be gone tomorrow. The order is our consensus of 5 test sources; the price is today's lowest including shipping.
Only models rated at least 4 stars by the stores that report customer ratings. Models without a rating fall outside this filter.
Score: consensus of the positions in 5 test sources, 100 = top of every source. Every model on this list is recommended by at least one test source. The bottom of a top list is still worth half the points, and a model named by only one source cannot score above 50. Only models sold in the United States count. Method.
Models without a ranking table of their own: none of our test sources recommends them, or their dock type has too few models for a fair comparison. We do track their prices.
