Updated October 2026
Data from Amazon and official Dreame and iRobot sites.
2026 verdict
Both robots map the home with LiDAR, so the dock settles it: the iRobot Roomba Plus 505 is the better robot vacuum of the two because it washes and dries its own mop pads.

Its AutoWash dock also lifts the pads over carpet, takes detergent, and the robot joins Apple HomeKit, SmartThings and Matter, with 5 GHz Wi-Fi on top. The Dreame D20 Pro Plus answers with 13000Pa of suction against 7000Pa, up to 285 minutes of runtime against 180 and a 3-year warranty against 1 year, and it is the lower priced of the pair. Its mop is a trailing pad you rinse and refill by hand. Pick the iRobot Roomba Plus 505 if mopping without chores or an Apple or Matter home matters, and the Dreame D20 Pro Plus for a large, mostly vacuumed floor on a tighter budget.

What the differences mean

Mop care

The iRobot Roomba Plus 505 dock washes the mop pads, dries them and the robot lifts them over carpet. The Dreame D20 Pro Plus drags a simple pad from a 0.35L tank that you rinse and refill yourself, so it suits light touch-ups more than a mopping routine.

Suction

13000Pa on the Dreame D20 Pro Plus against 7000Pa on the iRobot Roomba Plus 505 reads as a big gap on paper. Owners of the Dreame report mixed carpet results, so treat it as headroom for rugs rather than a guaranteed win.

Runtime and charging

Up to 285 minutes on the Dreame D20 Pro Plus covers a large single floor without a recharge stop, against 180 minutes on the iRobot Roomba Plus 505. The iRobot recharges faster, in 4.5 hours against 6.

Smart home

Both work with Alexa, Google Home and Home Assistant. Only the iRobot Roomba Plus 505 adds Apple HomeKit, SmartThings and Matter, and it also joins a 5 GHz network, where the Dreame D20 Pro Plus is 2.4 GHz only.

Warranty

The Dreame D20 Pro Plus carries 3 years against 1 year on the iRobot Roomba Plus 505, which counts on a machine full of brushes, motors and a self-emptying base.

What owners say

Owners of both robots open with the same praise: a map that comes out right on the first run and solid pet hair pickup across carpet and tile. After that they part ways. iRobot Roomba Plus 505 owners single out the AutoWash dock coming back mid-run to rinse the pads and drying everything at the end, while their complaints are noise, especially during the dock's self-cleaning cycle, and bumper or navigation errors a few months in, plus warranty trouble for units bought from third-party sellers. Dreame D20 Pro Plus owners talk about the big dust bag that lasts for months and runs quiet enough for a bedroom overnight, one of them across a commercial concrete floor, but their reports on suction and carpet pickup are contradictory, and some mention hair in the brush, bags jamming in the base and charging failures.

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.
