I’ve found that a few minutes of maintenance after the right tasks can make a big difference in suction, mopping quality, and dock performance. In this guide, I’ll walk you through how to clean Roborock S8 Pro Ultra the right way, what to clean, when to clean it, and the small mistakes that can shorten the life of the machine.
Why regular cleaning matters
The Roborock S8 Pro Ultra is built to do a lot of the work for you, but it is not fully hands-off. Dust, hair, dirty water, and detergent residue can build up over time. When that happens, you may notice weak suction, streaky floors, noisy brushes, or a dock that smells a little off.

It also helps protect the mop system, sensors, wheels, filters, and charging dock. In my experience, the units that stay clean on a schedule keep better map accuracy and need fewer deep-clean fixes later.
What parts of the Roborock S8 Pro Ultra need cleaning
A good cleaning routine starts with knowing which parts matter most. The S8 Pro Ultra has several components that need attention, and each one affects performance in a different way.
Common parts to clean include:
• Dustbin: Holds dirt, hair, and debris picked up during vacuuming.
• Main brush: Lifts dust and carpet debris, but hair can wrap around it fast.
• Side brush: Pushes dirt toward the suction path and can get tangled.
• Mop pads: Pick up wet messes and can hold grime if not washed.
• Water tanks: Store clean and dirty water for the mopping system.
• Filter: Traps fine dust and affects airflow.
• Sensors and charging contacts: Help the robot navigate and recharge properly.
• Dock trays and wash board: Can collect sludge, splash marks, and residue.

Before you start cleaning
Before you open anything, take a minute to prepare the robot and dock. This keeps the process simple and helps avoid accidental damage.
Do this first:
- Turn off the robot.
- Unplug the dock if you will be cleaning around water.
- Remove the robot from the dock.
- Empty the clean water and dirty water tanks if needed.
- Gather a soft cloth, lukewarm water, and mild soap if you plan to deep clean parts by hand.
I always recommend checking the user manual before using any cleaning agent. Harsh chemicals, hot water, or rough scrubbing can damage plastic parts, seals, and filters. A soft touch goes a long way here.
How to clean the dustbin and filter
The dustbin is one of the easiest parts to clean, and one of the most important. If it gets packed with dust, suction drops and odors can build up.
Follow these steps:
• Remove the dustbin from the robot.
• Open it over a trash can and empty all debris.
• Tap out loose dust gently.
• Rinse the dustbin with water if the model version allows it.
• Let it dry completely before putting it back.
The filter needs even more care. Gently brush off dust or tap it out, but do not wash the filter unless the manufacturer says it is washable. A wet filter can trap moisture and hurt airflow. From my own testing, a clogged filter can make the robot sound tired, like it is working too hard for every pass.
How to clean the main brush and side brush
Hair and string love the main brush. If you have pets or long hair in the house, this step matters even more. A tangled brush can reduce pickup power and make the motor work harder.
Here’s the best way to clean it:
- Remove the brush cover.
- Take out the main brush.
- Cut away wrapped hair or threads with small scissors or a cleaning tool.
- Wipe the brush chamber with a dry cloth.
- Check the side brush and remove debris or knots.
Do not force the brush back in if it does not sit smoothly. I once rushed this step and later noticed a rattling sound that turned out to be a strand of hair caught near the end cap. Small debris can cause bigger annoyances than you expect.
How to clean the mop pads
The mop pads do the wet work, so they need frequent washing. If you leave them dirty, they can start spreading grime instead of removing it.
You can clean them this way:
• Remove the mop pads from the mop plate.
• Rinse them with warm water.
• Use mild soap if the pads are greasy or stained.
• Rub them gently by hand until the water runs clearer.
• Air-dry them fully before reinstalling.
For best results, swap in fresh pads when the old ones start smelling musty or look worn. Clean mop pads help the S8 Pro Ultra leave a more even finish on tile, vinyl, and sealed hardwood. That is especially useful if you run mopping cycles often.
How to clean the clean water tank and dirty water tank
The tanks can quietly become the smelliest part of the whole system if you ignore them. Dirty water sitting too long creates buildup and odor, especially in warm rooms.
To clean them:
- Empty both tanks after use.
- Rinse the clean water tank with fresh water.
- Wash the dirty water tank with warm water and mild soap.
- Swirl the water around to loosen residue.
- Rinse until no soap remains.
- Leave both tanks open to dry.
If you notice slime, discoloration, or a sour smell, clean the tanks more often. In my experience, this is one of the easiest ways to keep the dock area from smelling like a forgotten mop bucket.
How to clean the auto-empty and wash dock
The dock does a lot of heavy lifting, but it also collects grime. If the dock is dirty, the robot can’t self-maintain as well as it should.
Focus on these parts:
• Wash board area: Wipe away sludge and debris buildup.
• Charging contacts: Clean with a dry cloth to help charging stay stable.
• Drain area and tray: Remove residue that can cause odor.
• Exterior surfaces: Wipe with a damp cloth to keep dust from piling up.
For the wash board and tray, use a soft brush or cloth instead of abrasive tools. A little buildup is normal, but thick grime can interfere with mop washing and create a bad smell. I like to check the dock weekly because dock maintenance is often the difference between “works fine” and “works like new.”
How to clean sensors and wheels
Sensors help the robot see, navigate, and avoid trouble. Wheels help it move smoothly across floors and over thresholds. If either one gets dirty, the robot may bump into things or behave oddly.
Clean them like this:
• Use a dry microfiber cloth on sensors.
• Wipe the cliff sensors, bumper area, and front-facing sensors gently.
• Check the wheels for hair or dust around the axles.
• Rotate the wheels by hand and remove trapped debris.
Never spray liquid directly on sensors or wheel assemblies. A dry cloth is usually enough. If the robot starts turning strangely or missing spots, dirty sensors are often the first thing I inspect.
How often should you clean the Roborock S8 Pro Ultra
The ideal schedule depends on how often you use it, whether you have pets, and how much dust your home collects. Still, a simple routine works well for most households.
A practical cleaning schedule:
• After each use: Empty dirty water, check the dock, and wash mop pads if needed.
• Every 2 to 3 days: Empty the dustbin and check for hair on the brush.
• Weekly: Clean sensors, wheels, dustbin, dock tray, and wash board.
• Every 2 to 4 weeks: Deep clean the filter, mop system, and tanks.
• As needed: Replace worn parts like brushes, mop pads, or filters.
This schedule is easy to follow and keeps maintenance from turning into a weekend chore. The key part of how to clean Roborock S8 Pro Ultra is consistency, not perfection.
Mistakes to avoid when cleaning
A lot of cleaning problems come from trying to “over-clean” the robot in the wrong way. I’ve seen more damage from carelessness than from normal wear.
Avoid these mistakes:
• Using hot water on sensitive parts.
• Washing non-washable filters.
• Reinstalling damp parts before they are fully dry.
• Using bleach, vinegar, or strong cleaners on plastic parts.
• Forcing the brush cover or mop assembly into place.
• Forgetting to clean the dock tray and water tanks.
These mistakes can shorten the life of the robot or leave you with odors, poor suction, or inconsistent mopping. When in doubt, gentler is better.
Extra tips for better long-term performance
If you want the S8 Pro Ultra to stay reliable, a few habits make a real difference. Think of them as small deposits into the robot’s long-term health.
Helpful tips:
• Run it on a consistent schedule so dust does not pile up.
• Trim long hair around brush areas before it tangles deeply.
• Keep the dock on a flat, dry surface.
• Empty and rinse the dirty water tank often.
• Replace consumables before they are fully worn out.
• Check the app for maintenance reminders and error alerts.
I also suggest doing a quick visual check once a week. A two-minute glance can catch a loose pad, a clogged wheel, or a dirty sensor before it becomes a real issue.
Benefits of keeping the S8 Pro Ultra clean
Clean maintenance is not just about appearance. It improves the way the robot cleans your home and helps it last longer.
Main benefits include:
• Stronger suction and better debris pickup.
• More even mopping results.
• Less odor from the dock and tanks.
• Smoother navigation and fewer errors.
• Longer life for brushes, filters, and pads.
• Less need for emergency deep cleaning.
A clean robot feels more dependable. It is a little like keeping a car’s tires filled and the windshield clear. The machine simply does its job better.
