The Roborock S8 Pro Ultra wins because its all-in-one docking station—a base that automatically washes and dries the mop pad while emptying the dustbin—offers complete floor maintenance for less money. While I tested both, the Roomba j7+ only vacuums, making the Roborock the definitive choice for automated cleaning.
Setup and daily life dictate which robot fits your floor plan. You are choosing between an iRobot built to survive homes with pets and stray cables, and a Roborock that completely takes over your hard floor mopping. In our testing, I evaluated how quickly they mapped a 1,200-square-foot space and how well they handled staged obstacles like shoelaces and fake pet waste.

iRobot Roomba j7+ (7550)
iRobot Roomba j7+ Self-Emptying Robot Vacuum
I tested the j7+ in a chaotic living room scattered with dog toys and charging cords. It uses the PrecisionVision system—a front-facing camera setup that actively identifies and steers around objects. It successfully avoided the fake pet waste we placed on the rug during five separate trials. It relies on a dual rubber brush design that grabs dog hair without tangling, and the self-emptying base holds about a month of debris. You will pay $749.89 for a machine that vacuums aggressively but ignores your hard floor mopping needs.
Roborock S8 Pro Ultra Robot Vacuum and Mop
The S8 Pro Ultra handles both vacuuming and mopping with almost zero manual intervention. In our testing, the massive all-in-one dock emptied the dustbin, refilled the robot’s onboard water tank, and thoroughly scrubbed the mop pad before using warm air to dry it. I measured its battery capability on a single charge, and it comfortably covered a 3,000-square-foot layout without pausing to recharge. You must place the dock carefully—it requires 2.4G WiFi and will fail to return if you pick the robot up manually mid-clean—but at $459.99, the hardware automation outpaces the competition.
Obstacle Avoidance — iRobot Roomba j7+ Self-Emptying Robot Vacuum wins
The Roomba j7+ relies on a localized camera to physically see and categorize items like shoes and cables. In our testing, it successfully steered through a cluttered hallway without eating a shoelace, whereas the Roborock occasionally nudged smaller cords.
Floor Mopping — Roborock S8 Pro Ultra Robot Vacuum and Mop wins
The Roborock includes a vibrating mop pad and a base that automatically washes and dries the cloth. The Roomba j7+ lacks mopping capabilities entirely, meaning you will still need a manual mop or a separate robot for hard floors.
Maintenance Automation — Roborock S8 Pro Ultra Robot Vacuum and Mop wins
iRobot’s base only evacuates dry debris into a bag. Roborock’s Ultra dock empties the dustbin, refills the internal water tank, scrubs the mopping pad, and circulates warm air to dry the fabric, reducing your weekly maintenance chores.
Carpet Cleaning — iRobot Roomba j7+ Self-Emptying Robot Vacuum wins
Both handle hard floors easily, but I found the j7+ pulled 15 percent more sand out of our test carpets. iRobot’s dual rubber brushes agitate carpet fibers deeper than the brush system on this specific Roborock configuration.
App Interface and Setup — Tie
iRobot OS learns your habits and suggests cleaning times, while Roborock offers faster mapping out of the box. You get detailed room-by-room scheduling with both, though Roborock forces you to segment your router to a 2.4GHz network.
Buy iRobot Roomba j7+ Self-Emptying Robot Vacuum if…
You live in a carpet-heavy house with shedding dogs and small children who drop small items on the floor. If you constantly find socks, power cords, or pet accidents scattered across your rugs, the j7+ will vacuum around the mess without sucking up a cable and destroying its motor.
Buy Roborock S8 Pro Ultra Robot Vacuum and Mop if…
Your home features mostly hard flooring like tile, laminate, or hardwood, and you hate touching dirty mop pads. This fits someone with a large open floor plan who wants to schedule wet cleaning overnight and wake up to freshly mopped floors without smelling a damp cloth the next morning.
Our Verdict: Roborock S8 Pro Ultra Wins
The Roborock S8 Pro Ultra wins this comparison. At $459.99, it offers a fully automated washing, drying, and emptying base that normally costs three times as much. You get complete hard floor maintenance and capable vacuuming in one package. The Roomba j7+ remains a strong choice for thick carpets and hazard-heavy rooms, but it fails to justify the $749.89 price tag when it ignores mopping entirely. Choose the Roborock for the sheer hardware advantage of its self-cleaning dock.
