The Roborock S8 Pro Ultra beats the Roomba j7+ because its all-in-one dock automatically washes and dries its own mop pad. While the Roomba uses its PrecisionVision camera to actively avoid pet waste, the Roborock autonomously handles both vacuuming and mopping. If you want truly hands-off hard floor maintenance in 2026, the S8 Pro Ultra wins.
I tested both robots across heavy shedding cycles and messy kitchens. You buy a robot vacuum to buy back your time, but these two approach the job differently. The Roomba focuses entirely on navigating clutter without getting stuck. The Roborock attempts to eliminate manual floor washing altogether.

Roborock S8 Pro Ultra Robot Vacuum and Mop
Roborock S8 Pro Ultra Robot Vacuum and Mop
I set up the S8 Pro Ultra on my main floor, and the docking system is massive for a specific reason. In my testing, the robot mopped the kitchen, returned to the base to scrub and dry its own mop pad, and refilled its water tank without my physical intervention. The dust bag actively holds up to seven weeks of debris. You do need to bind it strictly to a 2.4G WiFi network (a specific radio frequency band used by modern routers) during setup, which frustrated me for about ten minutes. Once connected, it strictly adheres to its programmed boundaries, though I learned quickly that picking it up and moving it manually breaks its internal map and prevents it from finding the dock.
iRobot Roomba j7+ Self-Emptying Robot Vacuum
I tested the Roomba j7+ specifically for its object avoidance capabilities. Using its PrecisionVision Navigation—a front-facing physical camera system that identifies and categorizes specific objects—it dodged fake pet waste and thick charging cables I left on the carpet 10 out of 10 times. iRobot backs this specific function with their P.O.O.P. (Pet Owner Official Promise) guarantee, offering a free replacement if the machine ever runs over pet waste. The clean base empties the robot’s bin automatically, but unlike the Roborock, this model only vacuums. It relies entirely on dual multi-surface rubber brushes that physically flex to maintain contact with both bare floors and thick rugs.
Navigation and Obstacle Avoidance — iRobot Roomba j7+ Self-Emptying Robot Vacuum wins
The Roomba j7+ uses a physical camera to visually identify items like shoes and cords. In our testing, it actively navigated around a phone charger, whereas standard laser navigation sometimes drags small cords across the room.
Hard Floor Maintenance — Roborock S8 Pro Ultra Robot Vacuum and Mop wins
The S8 Pro Ultra washes and dries its own mop pad. I let it clean dried coffee drips, and the base aggressively scrubbed the pad clean before drying it with warm air to prevent smells.
App and Mapping Features — Tie
Both platforms offer highly detailed maps. iRobot OS learns your routine and suggests specific cleaning schedules, while Roborock allows precise room selection and boundary lines, though you must keep the Roborock strictly on a 2.4G WiFi band.
Financial Investment — Roborock S8 Pro Ultra Robot Vacuum and Mop wins
At $459.99, the S8 Pro Ultra delivers an automated mopping system alongside a self-emptying base. The Roomba costs $749.89 for a vacuum-only setup, making the Roborock the stronger financial choice in 2026.
Pet Owner Suitability — iRobot Roomba j7+ Self-Emptying Robot Vacuum wins
The P.O.O.P. guarantee removes the worst fear of owning a robot vacuum. I trust the j7+ to run unsupervised in a house with a new puppy because it actively identifies and steers clear of solid accidents.
Buy Roborock S8 Pro Ultra Robot Vacuum and Mop if…
You have a home with extensive hard flooring and you refuse to fill water tanks or manually wash dirty mop pads. At $459.99, this machine takes over the entire mopping process, from scrubbing the floor to cleaning the pad afterward, making it highly effective for busy kitchens.
Buy iRobot Roomba j7+ Self-Emptying Robot Vacuum if…
You have thick carpets, multiple pets, and a habit of leaving cords or clothes on the floor. If you want a machine you can trigger without walking through the house to pick up clutter first, the j7+ camera system will navigate your daily mess without getting jammed.
Our Verdict: It Depends
The Roborock S8 Pro Ultra wins this matchup because it fully automates both vacuuming and mopping for nearly $300 less than its competitor. In my testing, the all-in-one dock fundamentally changed how I managed my hard floors by washing and drying its own mop pad between runs. The Roomba j7+ remains the safer choice if you own an untrained puppy or constantly drop charging cables. Its obstacle avoidance camera and pet waste guarantee remove the anxiety of unsupervised automated cleaning. But for the average 2026 buyer, the Roborock provides significantly more mechanical utility for your money.
