Which is better for carpet?

The Dreame X50 Ultra. Its 20,000 Pa suction and 20 mm mop lift handle thick carpet better than the Roomba's pad-lift system, which is aimed at low-pile rugs.

Is the Dreame worth $140 more?

If you have pets, thick carpet, or a large home, yes. The bigger bin and stronger suction cut down on dock trips. On mostly hard floors, the Roomba at $359 covers the job for less.

Which has the bigger dustbin?

The Dreame. It holds 0.85 gal onboard and 1.19 gal at the dock, versus 0.1 gal onboard for the Roomba.

Neither is quiet. Roomba buyers call the noise noticeable and the dock drying loud and slow. The Dreame's stronger suction also runs loud at max power.

Do both wash their own mop pads?

Yes. The Roomba's AutoWash Dock washes and dries the pads, and the Dreame dock washes pads with hot water. Both also empty the robot's bin.

Which is easier to set up?

The Dreame has the higher rating and fewer setup complaints. Roomba buyers report Wi-Fi and app problems during setup.

iRobot Roomba Plus 405 Combo vs Dreame X50 Ultra Robot Vacuum and Mop

The Roomba Plus 405 Combo is the better value at $359, and it is the one to pick if you want a self-washing mop dock for less money. The Dreame X50 Ultra at $499.99 is the stronger cleaner on paper: far more suction, a much bigger dustbin, and a mop that lifts higher for carpet. Choose the Roomba if budget and a proven app matter most; choose the Dreame if you have thick carpet, pets, or a big home and want fewer dock trips.
