|Sources: Amazon, ManufacturerDreame L20 Ultra Robot Vacuum and Mop vs iRobot Roomba Combo i5+ Self-Emptying Robot Vacuum and Mop
If you're choosing between the Dreame L20 Ultra Robot Vacuum and Mop and the iRobot Roomba Combo i5+ Self-Emptying Robot Vacuum and Mop, the Dreame L20 Ultra is the flagship option that excels in advanced features. With an impressive 6400mAh battery, it offers up to 260 minutes of runtime compared to the Roomba's 90 minutes, making it ideal for larger homes. What matters most here is the MopExtend™ technology in the Dreame, which extends the mop pad for effective edge cleaning, unlike the Roomba that requires manual bin swapping between modes. If you're after convenience and power, the Dreame L20 is a no-brainer for 2026, but the Roomba Combo could work if you're budget-conscious and need a lighter, easier-to-store option.
