What owners say

Dreame D20 Air Plus owners consistently rate its suction above older and pricier robots they have owned, and like the fast, accurate LiDAR mapping with editable maps and the anti-tangle brushes for pet fur, while their complaints are a water tank on the robot that must be refilled by hand and a mop that is a light refresh rather than a real scrub. iRobot Roomba 505X owners praise how little hands-on maintenance the AutoWash dock needs, refilling water and washing the mop pads for weeks at a stretch, and say it handles hardwood, tile and everyday carpet well, though several note the cleaning cycle runs loud and initial Wi-Fi or mapping setup can take patience.

Price history compared

Every price change of both, in the same store, so the gap between the two lines is what one costs more than the other.
