How we ranked these picks

We rank robot vacuums under $300 by what you get for the money, not by the biggest suction claim. LiDAR mapping, anti-tangle brushes, and a self-empty dock matter more than raw Pascal numbers at this price, so we weigh navigation first, then how often you touch the bin, then review depth to confirm reliability. Prices move often; every pick here usually sells for $300 or less.
