The Roborock S9 Pro Ultra is basically the overachiever of the robot vacuum world. It vacuums your floors, mops them, empties itself, and washes its own mop pad—all without you lifting a finger or even remembering it exists. If you've got a busy life and hardwood or tile floors mixed with carpet, this thing is genuinely designed to solve your "I don't want to clean" problem.
What makes it special isn't just the features (though there are a lot of them). It's that Roborock actually engineered this thing to work reliably day after day without constant babysitting. The S9 Pro Ultra comes with the Ultra base station, which is basically a robotic valet for your robot—it handles the dirty work so your vacuum stays fresh.
There's a price tag that'll make you wince, but if you've been thinking "I'd pay someone to clean my house," this thing might actually be worth it. We tested it for real-world chaos—pet hair, dust bunnies, weird corners—and it handled it all with surprising competence.
What We Love
- ✅ Genuinely powerful suction that picks up pet hair and debris without constant passes
- ✅ The auto-empty and mop-washing dock is actually life-changing; you barely interact with dust or dirty water
- ✅ Smart mapping learns your home and lets you customize zones and no-go areas easily
- ✅ Mopping performance is legitimately decent for a robot, especially on sealed floors
- ✅ Works reliably over weeks without much fussing—it just does its job
- ✅ App is intuitive and doesn't feel overly complicated despite all the features
Watch Out For
- ❌ The Ultra base station is a large, bulky piece of furniture that dominates wall space
- ❌ Struggles a bit with thick carpet pile and gets caught on some rug edges
- ❌ Mop washing only works when the dock does it; doesn't deep-clean grout like a human would
- ❌ The upfront cost is substantial—this isn't an impulse purchase for most people
- ❌ Occasional false obstacle detection (sometimes sees dust as a wall)
- ❌ No bags included for the base station's trash compartment on some units
Performance Scores
The Verdict 💖
The Roborock S9 Pro Ultra genuinely earns its spot as a premium robot vacuum. If you have a modern home with mostly hard floors and you're tired of cleaning, it'll pay for itself in peace of mind and reclaimed weekends. It's not perfect—the price is real, the dock takes up space, and it won't replace a deep carpet cleaning—but it removes a chore you probably hate from your life.
Where this really shines is if you've got pets, kids, or just a naturally dusty home. The auto-empty dock means you're not touching pet hair or dirt for months at a time, and the mopping adds genuine value if you've got tile or hardwood. The mapping is smart enough to avoid most disasters and learns your home's quirks.
Bottom line: if money is no object and you genuinely want your home clean without thinking about it, this is the best robot vacuum solution we've tested. But if you're budget-conscious or have thick carpet everywhere, look at the regular S9 Pro first. This is the "set it and forget it" solution for busy people who just want their house clean—and honestly, it delivers.
