|Sources: Amazon, ManufacturerRoborock S8 Pro Ultra Robot Vacuum and Mop vs iRobot Roomba Combo i5+ Self-Emptying Robot Vacuum and Mop
If you're looking for the ultimate cleaning experience, the Roborock S8 Pro Ultra Robot Vacuum and Mop is the premium option here, boasting a powerful 6,000 Pa suction and the innovative RockDock Ultra for hands-off maintenance. In real-world use, this flagship model's ability to wash, dry, and refill makes it a standout for busy households in 2026. On the other hand, the iRobot Roomba Combo i5+ Self-Emptying Robot Vacuum and Mop offers a more budget-friendly solution with its Clean Base® that can hold up to 60 days of debris. However, it requires manual bin swaps to switch between vacuuming and mopping modes, making it less convenient for users who want seamless transitions between tasks.
