Dreame D20 Plus
Score: 83/100
iRobot Roomba Plus 504
Score: 78/100Rankings

The Dreame D20 Plus combines 13,000 Pa suction with an anti-tangle DuoBrush and a 3.5 L water tank for simultaneous vacuuming and mopping. Its internal 0.5 L dust bin fills quickly and the base station is bulky, which can limit convenience. Ideal for tech-savvy users in spacious single-level homes who value smart integration.

The iRobot Roomba Plus 504 is a vacuum-only robot with 150x power-lifting suction and a 210-minute runtime, paired with an AutoEmpty dock that can go up to 75 days between emptying. It lacks mopping functionality and its total weight of over 16 lb can be cumbersome to move. It is best suited for pet owners who prioritize strong suction and low-maintenance vacuuming on mixed floors.
