Honestly, looking at the robot vacuum market right now is exhausting. Every other month, there's a new "flagship" that promises to solve all your problems, only to get stuck on a stray sock or leave a distinct line of dust along your baseboards. But the Roborock Qrevo Master feels a bit different. It’s not just another incremental update; it's basically Roborock admitting that the previous Qrevo models had a few blind spots—literally.
If you’ve ever owned a round robot, you know the "corner problem." They get close, but they can't quite reach that last inch of dust. The Qrevo Master fixes this with something they call the FlexiArm Design. It’s basically a little robotic arm for the side brush that physically swings out when the sensors detect a corner. It looks kinda cool, like the robot is reaching out to grab dirt, and it actually works. You aren't left with those annoying little triangles of pet hair in the corners of your kitchen anymore.
The 10,000 Pa Elephant in the Room
Let’s talk about suction. We’ve reached a point where numbers are getting a bit ridiculous. The Qrevo Master boasts 10,000 Pa of HyperForce suction. To put that in perspective, a few years ago, 2,500 Pa was considered "premium." Does the extra 7,500 Pa make a difference?
On hardwood? Not really. A hairdryer could probably pick up crumbs on a flat surface. But on medium-pile carpets? Yeah, you notice it. It pulls up the fine, sandy grit that usually settles at the bottom of the carpet fibers where other vacuums just glide over.
10,000 Pa is a lot of power.

It also uses a DuoRoller Riser system. Instead of one rubber brush, you get two counter-rotating rollers. This is a massive win for anyone with long hair or pets. Single rollers tend to turn hair into a tight "birds nest" around the axle. With the dual rollers, the hair is squeezed and moved more efficiently into the dustbin. It’s not 100% tangle-free—nothing is—but it's significantly better than the old-school bristled brushes that you had to cut hair off of with a seam ripper every Sunday.
Why the "Master" Dock is a Game Changer
The dock is where most of the "Master" branding comes into play. It’s the Multifunctional Dock 3.0, and it’s surprisingly self-sufficient.
- Hot Water Washing: It washes the mop pads with 60°C (140°F) water. Cold water just moves grease around; hot water actually breaks it down. If you’ve ever mopped a kitchen floor after cooking bacon, you know why this matters.
- Self-Cleaning Base: This is the big one. Most "self-cleaning" docks actually require you to scrub the bottom of the dock every few weeks because gunk builds up where the mops are washed. The Qrevo Master has built-in scrapers that clean the cleaning tray while it washes the mops.
- Warm Air Drying: After the wash, it blows 45°C air over the pads. This prevents that "sour towel" smell that happens when damp mops sit in a dark dock for two days.
Real Talk on Navigation and AI
Roborock uses PreciSense LiDAR, which is essentially the gold standard for mapping. It’ll map your house in about 15 minutes. However, the Qrevo Master also includes Reactive AI obstacle recognition.

It has an RGB camera and structured light. It can recognize 62 different types of objects. This sounds impressive, but in the real world, it's a bit of a mixed bag. It’s great at avoiding shoes, scales, and power strips. It’s still a little "iffy" with thin charging cables. If you leave a black USB-C cable on a dark floor, there’s a 50/50 chance the Master will try to eat it.
The camera also allows for two-way video calling. You can literally drive the robot like a remote-control car and talk to your dog while you’re at work. Is it necessary? Probably not. Is it fun to watch your cat’s confused face from a floor-level perspective? Absolutely.
The Mopping Situation
The Qrevo Master uses dual spinning mops rather than a vibrating plate. These spin at 200 RPM while applying consistent downward pressure.
One of the mops also has the FlexiArm treatment. When the robot is mopping along a wall, the right-side mop physically extends outward to flush against the baseboard. This eliminates that 1-inch "gap" that almost every other robot leaves behind.

When it hits a carpet, it lifts the mops by 10mm. That’s enough for low-pile rugs, but if you have thick, shaggy rugs, the wet mops might still graze the fibers. If that’s your house, you’re better off setting the app to "Vacuum Carpets First" so it does the rugs while the mops are still bone-dry.
Is It Actually Worth the Money?
This isn't a cheap machine. It sits in that premium bracket where you're paying for the convenience of not thinking about your floors for weeks at a time.
The "SmartPlan" feature is actually pretty decent for people who don't want to mess with settings. It uses AI to look at the room type and the floor material and then decides: "Okay, the kitchen needs a deep mop with high water flow, but the bedroom just needs a light vacuum." It takes the guesswork out of the app, which can be a bit overwhelming with its 50 different sub-menus.
The Downsides:
The dock is big. It’s tall, and it’s wide. You need a dedicated spot for it, and it isn't exactly "discreet" home decor. Also, while the brushes lift up when vacuuming to avoid cross-contamination, the robot can still be a bit noisy when it's running at full 10,000 Pa suction. It’s not "jet engine" loud, but you definitely aren't watching a movie in the same room while it's in Max+ mode.
Actionable Maintenance Tips
To keep this thing running like it's brand new, don't just "set it and forget it" for six months.
- Check the Brush Bearings: Even though it’s "tangle-free," hair likes to migrate to the ends of the rollers. Pop the rollers out once a month and clear the hair from the side caps.
- Clean the Sensors: Every few weeks, wipe down the cliff sensors and the front camera lens with a microfiber cloth. If the "eyes" are dusty, the obstacle avoidance gets stupid.
- The Dirty Water Tank: Even with the hot water wash, that dirty water tank will start to smell if you leave it for a week. Dump it as soon as it’s full and give it a quick rinse with some dish soap.
- Filter Care: Tap the dustbin filter against the side of a trash can once a month. If it's clogged, that 10,000 Pa suction drops significantly.
If you're coming from an older robot vacuum, or even one of the early Qrevo models, the jump in edge cleaning and dock maintenance is the biggest "quality of life" upgrade you'll actually notice on a daily basis. It handles the corners, it washes its own "feet" with hot water, and it generally just stays out of your way.
