Data from Amazon and official Dreame and iRobot sites.

It also costs less and runs far longer per charge, 285 minutes against 120, with a three year warranty against one. The iRobot Roomba Max 705 holds its own with broader smart home reach, including Matter, Apple HomeKit and Samsung SmartThings the Dreame does not document, plus dual-band Wi-Fi and PrecisionVision AI obstacle avoidance. Both navigate with LiDAR, support multi-room mapping and no-go zones, and self-empty their own dustbin at the dock. Choose the Dreame D20 Pro Plus for a lower price, longer runtime and a mop thrown into the same pass; choose the iRobot Roomba Max 705 if you specifically want a dedicated vacuum with the widest smart home ecosystem support.

What owners say

Owners of both robots like how accurately each maps a home, but they diverge everywhere else. Dreame D20 Pro Plus owners describe correct room detection on the first run even across mixed carpet and tile, and one operator runs four of them across a 45,000 sq ft self-storage facility, though others report contradictory suction on thicker rugs, dust bags jamming in the base and occasional charging failures. iRobot Roomba Max 705 owners instead praise mapping that is faster and more accurate than the older Roombas they replaced, and call the AutoEmpty dock a genuine convenience win, while the most common complaint is a WiFi setup that rejects router passwords with special characters. Neither group reports a self-emptying dock going more than a couple of months untouched.

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.
