|Sources: Amazon, ManufactureriRobot Roomba Combo j9+ Auto-Fill Robot Vacuum and Mop vs Dreame L10s Ultra Robot Vacuum & Mop
The Dreame L10s Ultra Robot Vacuum & Mop is the better buy for most people - its fully automated base station and 5,300Pa suction crushes the iRobot Roomba Combo j9+. If you're looking for a truly hands-free experience, the Dreame’s capabilities make it worth every penny. In real-world use, the Dreame L10s Ultra can run up to 210 minutes on a single charge, meaning it can clean more space without needing to recharge. Meanwhile, the iRobot Roomba Combo j9+ lasts 120 minutes, which is decent but falls short if you have a large area to cover. The difference in mopping features is significant as well, with the Dreame washing and drying its mop pads automatically while the iRobot requires manual maintenance.
