Both Roomba Combo j9+ and Roborock S7 MaxV Ultra look similar with a round shape and black color, but the Combo j9+ has an elegant gold finish that adds a touch of luxury to its design.The Combo j9+ also has a shorter profile, measuring 3.4 inches in height and 13.7 inches in diameter, making it more compact and easier to maneuver under furniture. The S7 MaxV Ultra, on the other hand, is slightly taller at 3.8 inches and has a larger diameter at 13.8 inches, which may limit its ability to fit under low-height furniture.

It is also worth noting that the dock of the Roborock model is quite bulky and can take up a lot of space, while the Roomba Combo j9+ has a more stylish-looking docking station. The dock of the Combo j9+ also has a wood veneer top on which you can place decorative items, making it blend in easily with your home decor.

Both Roomba Combo j9+ and Roborock S7 MaxV Ultra are equipped with advanced cleaning technologies that allow them to clean different surfaces and tackle various types of dirt, debris, and pet hair.

The Roomba Combo j9+ offers a 4-Stage Cleaning System consisting of Dual Multi-Surface Rubber Brushes, an Edge-Sweeping Brush, a Power-Lifting Suction, and an Auto-Retract Mopping System that lifts the mop automatically when it detects carpets.

One notable cleaning feature of the Combo j9+ is the Dirt Detective, which learns past cleaning missions to create an effective cleaning plan that prioritizes the dirtiest room first. The Combo j9+ also features 2 Cleaning Passes to clean each room thoroughly and the SmartScrub which mops stubborn stains back and forth with a consistent pressure of 1.16 lb.

The Roborock S7 MaxV Ultra, on the other hand, features a VibraRise Mopping System, which uses sonic vibration technology that vibrates at 3000 times per minute to scrub away stubborn stains and dirt. Just like the Combo j9+, it also automatically lifts the mop away from carpets with its Intelligent Mop Lifting, so you can get mopped floors and vacuumed carpets in one go.

The S7 MaxV Ultra also has a strong suction power of up to 5100Pa, which makes it very effective in picking up dirt and debris from carpets and hard floors. It also comes with a durable all-rubber Floating Brush to avoid tangling with pet hair and adjust to uneven floors for thorough cleaning.

Roborock S7 MaxV Ultra combines PreciSense LIDAR Navigation, Structured Light 3D Scanning, and an RGB Camera to learn the layout of your home and create editable maps that allow you to customize your cleaning schedules, set no-go zones, adjust preferences for each room, and more.

The Roomba Combo j9+ also has advanced navigation features, including the PrecisionVision Navigation, which identifies and avoids obstacles and hazards like shoes, socks, cords, pet waste, and more. It even has the Pet Owner Official Promise (P.O.O.P.), which guarantees a replacement if your robot accidentally picks up solid pet waste.

iRobot Roomba Combo j9+ also produces a complete map of your home, so you can easily customize your cleaning schedule, cleaning preferences, and spot-clean specific areas using the iRobot Home App or voice commands with Alexa, Siri, or Google Assistant.

One thing that sets both models apart is their dock. Roborock S7 MaxV Ultra comes with a fully-automated Empty Wash Fill Dock which can self-empty bins for up to 7 weeks, self-refill the robot water tank for an extended mopping range, self-wash the mop during and after cleanup, and self-clean the robot for easier maintenance. This complete autonomy allows you to have your home clean with very minimum interference.

The Roomba Combo j9+, on the other hand, comes with a Clean Base Auto-Fill Dock, which can self-empty bins for up to 60 days and self-refill liquid for up to 30 days. This is also a great feature for hassle-free cleaning, but unlike the Roborock model, you will still have to manually wash the mop and clean the robot frequently for maintenance.
