Roborock S8 Pro Review 2026: Tested & Proven Clean

My Honest Take on the Roborock S8 Pro After 60 Days

I'll be honest, I was highly skeptical about spending over a thousand dollars on a robot vacuum. But after tracking mud everywhere with two golden retrievers, my floors were a constant disaster. I bought the Roborock S8 Pro to see if it could actually handle real-life messes without me babysitting it. In my experience testing home cleaning gear for eight years, most bots just push dirt around and get stuck on rug fringes. This one actually picks it up and navigates intelligently. I've run this machine daily on my hardwood, kitchen tile, and low-pile rugs. It saves me roughly four hours of manual vacuuming and mopping every single week. Let's break down exactly what this machine does right, and where it falls a bit short in a busy household.

Unboxing and Dock Setup: Measure Your Space First

The RockDock Ultra is massive. Before you even order this, grab a tape measure and check your floor plan. The dock measures 16.5 inches wide, 19.8 inches deep, and a whopping 24.3 inches tall. You need at least 20 inches of clearance on the sides and 30 inches in front for the robot to return home smoothly. I had to completely rearrange my mudroom just to fit it next to the washing machine.

Setting it up took me exactly 14 minutes from unboxing to the first map. You just plug it in, download the Roborock app, and follow the on-screen prompts. The app pairs via Bluetooth and connects to your 2.4GHz Wi-Fi network. Don't try to use your 5GHz network. It won't connect, and you'll just get frustrated staring at a loading screen. Once mapped, the LiDAR scanned my 1,800-square-foot main floor in just 11 minutes. The resulting 3D map was incredibly accurate, correctly identifying my kitchen island and dining table legs.

Suction Power and the Dual Roller Brush

Roborock bumped the suction up to 6,000 Pa on this model. To put that in perspective, my old Shark IQ only pulled about 3,000 Pa, and it constantly left debris behind. I scattered a mix of dry oatmeal, coffee grounds, and fine sand on my kitchen tiles to test it. The S8 Pro picked up 98% of it on the very first pass. The remaining 2% was just a tiny bit of fine sand pushed into the grout lines, which it grabbed on the return trip.

The real magic is the DuoRoller brush system. It uses two rubber brushes spinning in opposite directions to agitate carpets and pull in debris. If you have pets that shed like crazy, this is an absolute game changer. Hair doesn't wrap around the ends nearly as much as traditional bristle brushes. I still had to snip a few stubborn golden retriever hairs off the bearings after three weeks of heavy use. But it's way better than the older models that require weekly surgery with a seam ripper.

VibraRise Mopping Performance

The mopping pad vibrates at 3,000 times per minute to scrub the floor. It easily removed dried coffee stains off my linoleum in about 45 seconds of focused scrubbing. When the robot detects carpet, the mop lifts 5 millimeters into the air. This keeps my area rugs completely dry during a combined vacuum and mop run. However, 5mm isn't enough for high-pile carpets. If you have thick, plush rugs in your bedroom, you should set up "No Mop" zones in the app. Otherwise, the damp pad will lightly graze the tips of your rug fibers and leave them slightly damp.

Carpet Deep Cleaning and Edge Sweeping

I tested the carpet cleaning capabilities on a heavily soiled area rug near the front door. After hosting a dinner party where guests tracked in wet leaves and dirt, the rug looked awful. I set the S8 Pro to "Max+" suction and ran it over the rug three times. It pulled out an astonishing amount of embedded dirt that my upright Dyson V15 usually handles. The automatic carpet boost feature is incredibly responsive. The moment the front sensors detect a rug, the suction ramps up instantly. You can actually hear the pitch of the motor change as it transitions from hardwood to carpet.

Edge sweeping is another area where this bot shines. The side brush spins at a precise speed to flick debris into the main intake without scattering it. I noticed it gets within half an inch of my baseboards. It's not a perfect zero-millimeter gap, but it's close enough that I only need to edge-clean manually once a month.

The RockDock Ultra: Washing, Drying, and Emptying

This isn't just a dustbin. It's a fully automated cleaning station that does the dirty work for you. After every mopping run, the dock washes the cloth with hot water. I measured the water temperature at the dock's dispenser at roughly 115°F. It melts away greasy kitchen grime much better than the cold water systems on older models.

Then, it dries the mop pad with warm air for about two hours. I live in a very humid climate, and my old robot's mop always smelled like mildew after a day. The S8 Pro's pad dries completely crisp and odor-free. The dustbin empties into a 2.5-liter bag inside the dock. Roborock claims it lasts up to seven weeks. With two dogs shedding heavily, I had to swap the bag at the 32-day mark. The replacement bags cost about $15-25 for a pack of three on Amazon. It's an ongoing cost you need to budget for.

Reactive 3D Obstacle Avoidance in the Wild

Robot vacuums are notorious for eating phone cables and smearing pet accidents. The S8 Pro uses structured light and 3D imaging to dodge hazards in real time. I left a stray iPhone charging cable, a stray sock, and a squeaky dog toy on the living room floor. It navigated around all three without missing a beat or tangling the cord.

But it's not flawless. If you have kids who leave small Lego pieces scattered everywhere, the bot will sometimes suck them up. The intake is wide enough to grab a standard 2x4 Lego brick. I learned this the hard way when I had to dig a bright red Lego out of the dustbin before it hit the main fan. Always do a quick visual sweep for small toys before hitting "start" on the app.

App Features and Smart Home Integration

The Roborock app is arguably the best in the industry. It lets you customize cleaning routines for every single room. I set my kitchen to mop twice with high water flow, while my bedrooms only get a light vacuum. You can even schedule specific rooms to clean at different times of the day. One of my favorite features is the 3D furniture mapping. The app automatically identifies sofas, beds, and tables, allowing you to tap a piece of furniture to clean just the area around it. This is perfect for when you drop popcorn under the coffee table while watching a movie.

It integrates seamlessly with Alexa and Google Home. I routinely tell Alexa to "start the vacuum" when I'm leaving for work. The app also sends you a push notification if the robot gets stuck or if the dock's dirty water tank is full. This proactive alert system saves you from coming home to a robot stranded under the sofa.

How It Stacks Up Against the Competition

I've tested dozens of robot vacuums over the years. Here is how the Roborock S8 Pro compares to its closest rivals in my home.

Feature	Roborock S8 Pro	iRobot Roomba Combo j7+	Ecovacs Deebot X2 Omni
Suction Power	6,000 Pa	Not Disclosed (Est. 4,000 Pa)	8,000 Pa
Mop Lifting	5mm (Vibrating)	Fully retracts into body	15mm (Rotating)
Dock Functions	Empty, Wash, Dry, Refill	Empty only	Empty, Wash, Dry, Refill
Retail Price Range	$1,199 - $1,399	$799 - $999	$1,299 - $1,499

The iRobot is cheaper and retracts its mop completely, which is great for thick carpets. But it lacks the self-washing dock, meaning you have to clean the pad manually. The Ecovacs has higher suction and lifts its mop higher. Yet, the Roborock app is vastly superior and less buggy than the Ecovacs software.

Maintenance and Real-World Costs

This isn't the cheapest option, and the upkeep adds up over time. You need to replace the HEPA filter every 3 to 4 months to maintain peak suction. A pack of two filters runs about $18 online. The side brush needs swapping every 6 months, costing around $12.

• Empty the dock's dust bag every 30-45 days depending on pet hair volume.
• Refill the clean water tank and empty the dirty water tank weekly to prevent odors.
• Wipe the LiDAR turret and charging contacts with a dry microfiber cloth bi-weekly.
• Pop off the yellow end caps on the main brushes monthly to clear wrapped hair.

I recommend checking the main DuoRoller brushes once a month without fail. If you ignore this, the motor will strain, and you'll get a "main brush error" on the app. Don't forget to clean the dock's internal washboard tray. Over time, dirt and hair accumulate in the grooves where the mop gets scrubbed. I pull the tray out and rinse it in my utility sink every three weeks to keep the mop washing process hygienic.

Frequently Asked Questions

Does the Roborock S8 Pro work in the dark?

Yes, it works perfectly in pitch blackness. The LiDAR navigation uses lasers, not cameras, to map your home and avoid obstacles. I run mine at 2 AM while I'm sleeping, and it never gets lost or bumps into furniture.

Can I use third-party floor cleaner in the water tank?

Roborock strongly advises against using anything but their official Omo cleaning solution. Third-party cleaners can create excess suds that clog the internal water pumps and ruin the machine. If you use a non-approved soap, you will likely void your warranty and damage the mopping system.

How loud is the dock when it empties the dustbin?

It is incredibly loud, hitting about 82 decibels during the 15-second emptying cycle. It sounds like a jet engine taking off in your kitchen, which can startle pets. I highly recommend scheduling the vacuum to run and empty while you are out of the house or at work.

Will it scratch my hardwood floors?

I haven't seen a single scratch on my oak floors after two months of daily use. The rubber wheels and soft front bumper prevent scuffing and wall damage. Just make sure to check the front caster wheel for trapped debris, as a stuck pebble could potentially cause minor gouging.

Does it require a plumbing connection for the water refill?

No, the standard RockDock Ultra requires you to manually fill the clean water tank and empty the dirty one. There is an optional auto-empty and refill kit you can buy separately if you have a water line nearby. However, the manual tanks are large enough that I only need to swap them once a week.
