It runs up to 285 minutes, carries a 500ml onboard bin and a three year warranty, and empties into a 5L bag rated for up to 150 days. The iRobot Roomba Combo 10 Max robot + AutoWash dock is the one that actually cleans its mop, washing and drying the pad at the dock and refilling its water, and it reaches far more smart home platforms, from Apple Home and SmartThings to Home Assistant and Matter. The iRobot is also the only one of the two that mops in any meaningful sense, while the Dreame's trailing pad is a light wipe. Pick the Dreame D20 Pro Plus for value and long hands-off runs, and the iRobot Roomba Combo 10 Max robot + AutoWash dock for a self-washing mop and the widest platform support.

What the differences mean

Mop

The iRobot Roomba Combo 10 Max robot + AutoWash dock washes and dries its mop pad at the dock and refills its water, while the Dreame D20 Pro Plus only drags a trailing pad fed from a 500ml tank with no washing or drying. If mopping matters, the iRobot is the one that does it.

Runtime

The Dreame D20 Pro Plus is rated at up to 285 minutes and the iRobot Roomba Combo 10 Max robot + AutoWash dock at 175. On a large floor the Dreame finishes in one pass where the iRobot may need to recharge and resume.

Warranty

The Dreame D20 Pro Plus carries a three year warranty and the iRobot Roomba Combo 10 Max robot + AutoWash dock one year. On a machine with a battery and a motor this is the longest cover in the comparison.

Onboard bin

The Dreame D20 Pro Plus holds a 500ml onboard bin against 300ml on the iRobot Roomba Combo 10 Max robot + AutoWash dock, and empties into a 5L bag rated for up to 150 days, where the iRobot does not publish its dock bin size.

Connectivity and platforms

The iRobot Roomba Combo 10 Max robot + AutoWash dock connects over 2.4GHz and 5GHz Wi-Fi plus Bluetooth and works with every major platform. The Dreame D20 Pro Plus is 2.4GHz only, has no Bluetooth and covers just Alexa, Google Home and Home Assistant.

What owners say

Owners of both robots put a dock that empties itself at the centre of the experience, and both sets of reviews treat mopping as secondary. Dreame D20 Pro Plus owners praise mapping that gets rooms right on the first run, good pet-hair pickup, quiet overnight runs and durability under heavy use, while a vocal minority report weak suction, hair stuck in the brush, debris smeared by the pad, jamming bags and charging failures. iRobot Roomba Combo 10 Max robot + AutoWash dock owners praise its mapping and improved mopping when it works, but many describe stopped jobs, relocalization failures, dead batteries near the dock and bin or dirty-water errors after the first months, with slow support.

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.
