|Sources: Amazon, ManufactureriRobot Roomba Combo j9+ Auto-Fill Robot Vacuum and Mop vs ECOVACS DEEBOT T30S COMBO Robot Vacuum & Mop + Handheld Vacuum
The ECOVACS DEEBOT T30S COMBO Robot Vacuum & Mop + Handheld Vacuum is the smarter buy for most people due to its impressive 11,000 Pa suction power, which crushes the iRobot Roomba Combo j9+ Auto-Fill Robot Vacuum and Mop's unspecified suction strength. If you're looking for a comprehensive cleaning solution in 2026, the DEEBOT's ability to auto-clean its mop with 158°F water is a game-changer. In real-world use, the iRobot Roomba Combo j9+ excels with its Clean Base Auto-Fill Dock that empties debris for up to 60 days. However, it falls short with manual mop pad washing and slower navigation. The DEEBOT's advanced features make it a no-brainer for anyone serious about cleanliness and efficiency in their home cleaning routine.
⚖️ Weight: 143.92 oz vs 144.62 oz🏷️ Suction Power: 100% stronger vs 11,000 Pa🔋 Battery: 4460 mAh vs 5200 mAh
