It reaches Apple Home, SmartThings and Matter where the Dreame D20 Pro Plus stops at Google Home, Alexa and Home Assistant, and its AutoWash dock washes and dries the mop automatically, a chore the Dreame's simple trailing pad leaves to the owner. The Dreame D20 Pro Plus counters with a much longer warranty, extra runtime, and nearly double the suction rating, plus the lower price of the two. Both self-empty their bin and map with LiDAR. Buyers chasing raw suction and battery life at a lower cost should look at the Dreame D20 Pro Plus; anyone who wants the mop maintained automatically and a wider smart home reach should pick the iRobot Roomba 505X.

What owners say

Owners of both machines like how little they have to do with the bin, but split from there. Dreame D20 Pro Plus owners describe accurate first-run mapping across mixed carpet and tile and praise how long the 5L bag lasts between changes, while flagging suction that some find strong and others weak on carpet, a mop pad that only trails rather than scrubs, and the occasional charging failure or jammed bag. iRobot Roomba 505X owners lead with the AutoWash dock itself, describing weeks of not touching the machine as it empties, refills and washes its own mop pads, and note it handles pet hair and daily dust reliably on hardwood and tile. Their complaints run the other way: a cleaning cycle several call genuinely loud, and a WiFi or mapping setup that took more than one attempt for a few buyers.

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.
