Dreame L20 Ultra Robot Vacuum and Mop vs Roborock Q7 Max+ Robot Vacuum + Mop with Auto-Empty Dock
If you're after the ultimate clean, the Dreame L20 Ultra Robot Vacuum and Mop is the flagship option that shines with its 7,000 Pa suction power. In real-world use, this means it can tackle everything from fine dust to stubborn pet hair with ease. On the flip side, the Roborock Q7 Max+ Robot Vacuum + Mop with Auto-Empty Dock holds its ground as a solid mid-range choice, especially with a hands-free auto-empty dock that can handle up to 7 weeks of debris without you lifting a finger. The Dreame's MopExtend™ technology physically extends the mop pad for edge cleaning, which is a game-changer for tight corners. Meanwhile, the Roborock features a 4,200 Pa suction, which is still impressive but doesn’t quite match the flagship's power. If you have low furniture, you might appreciate the Roborock's lower height of 3.80 inches, making it more versatile for those hard-to-reach spots in your home.
