91 models are on sale today for $300 or less, shipping included. Ranked by our score from lab tests 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 lab tests and owners’ ratings. The price is today’s lowest including shipping.
Mopping freshens the floor; real stains rarely come off. Spinning or roller mops paired with self-cleaning stations deliver the most effective floor cleaning.
Only models rated at least 4 stars from at least 20 reviews at the stores that report customer ratings. Models with fewer reviews or without a rating fall outside this filter.
Score out of 10: 60% lab tests, 25% owners’ ratings at the stores that ship to the United States, 15% the maker’s facts. Price does not count. Only models a lab has tested are ranked, and only models sold in the United States count. Method.
Ranked models, biggest discount first
Every model in our ranking on one list. The number is its place within its own station type.
