The best robot vacuum under $300 in 2026
9 models are on sale today for $300 or less, shipping included. Ranked by our score from test-site results and owners’ ratings. The list moves with the prices.
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 score from test-site results and owners’ ratings. The price is today’s lowest including shipping.
