Most Xiaomi robot vacuum cleaners have to be cleaned or replaced after 3-6 months of active use. But how to remove them so as not to break the mounts or damage the mechanism? In this article, step-by-step instructions for all types of brushes (side, main, turbo), analysis of typical errors and maintenance tips.
Xiaomiβs official guidelines often keep nuanced, such as how to handle boiling axles or how to lubricate bearings after cleaning, and weβve compiled expert advice based on service center experience and user feedback so that the process takes no more than 10 minutes β even for beginners.
If your vacuum cleaner is getting worse at picking up garbage, creaking loudly, or leaving stripes, that's a sure sign that your brushes are demanding attention, but before you grab the screwdriver, make sure that it's them, not a clogged filter or a worn-out battery, and it's easy to check that by turning the vacuum cleaner on a flat surface and seeing if the brushes are rotating evenly, if one of them is standing still or spinning in jerks, it's time to act.
In this article, we will look at:
- π§ How to remove side brushes (including fast-mount models)
- π Step-by-step dismantling of the main brush (including models with a turbo brush)
- β οΈ Common errors that lead to breakage of fasteners
- π οΈ How to clean your brushes so they last longer
1.Preparation: What will be required for the work
Before you start dismantling, prepare the tools and the workplace, which will save time and save you from losing small parts.
You will need to:
- βοΈ Flat screwdriver (or plastic mediator) - for slapping latches
- π§΄ Silicone lubricant or WD-40 β if the brushes are stiff
- π§Ό Warm water with soap and a soft brush (for example, a toothbrush)
- π¦ Container for small parts (cogs, springs)
- πΈ Smartphone β to photograph the location of parts before dismantling
If you have a turbo brushed model (e.g. Xiaomi Mi Robot Vacuum-Mop 2 Pro or Dreame) D9), additionally prepare a cross screwdriver - it will be needed to unscrew the fixing screw.
β οΈ Warning: Do not use metal tools to clean plastic parts - they leave scratches that accumulate dirt over time.
Work on a table covered with light cloth or paper, so you don't lose any small details and you'll notice springs or rubber seals falling out. If the vacuum cleaner is heavily polluted, you should first vacuum it by hand so that the debris doesn't interfere with the disassembly.

Before starting work, completely discharge the vacuum cleaner battery - this will eliminate accidental inclusion during dismantling.
Removal of side brushes: step-by-step instructions
Side brushes are the easiest to dismantle, but they also have their own characteristics. In most Xiaomi models (for example, Mi Robot Vacuum). 1S, Viomi V2) They are mounted on latches, but in some series (Dreame Bot) it may be necessary to unscrew the screw.
Algorithm of action:
- Turn the vacuum cleaner up with your wheels and find a side brush.
- Press the lock (usually located on the inside of the mount) and pull the brush over yourself.
- If the brush does not lend itself, gently tuck it with a plastic screwdriver from the outside.
- Remove the rubber cap (if any) and pull out the spin axis.
In fast-mount models (such as the Xiaomi Mi Robot Vacuum-Mop P), the brush is removed with one motion: press the lock button and pull down. Don't put too much effort β if something doesn't work out, check if the axis is clogged with hair.
Make sure the vacuum cleaner is off.|Find the lock (button or latch)|Prepare a container for small parts|Check if there are any visible axis damages-->
After removal, inspect the bearing (metal or plastic sleeve) for wear. If it has a backlash of more than 1 mm or creaks when rotating, it is time to replace the brush. Otherwise, cleaning and lubrication will suffice.
β οΈ Attention: In Viomi models V3 dreame Z10 Pro side brushes are magnetically attached. Don't try to pull them out by force, just pull them down with a slight counterclockwise turn.
3. Dismantling of the main brush: disassembly and nuances
The main brush (roller brush) is the most difficult element to remove, and depending on the Xiaomi model, it can be mounted on latches, screws or a combination of latches, and consider a universal algorithm that is suitable for 90% of the Mi Robot and Dreame series vacuum cleaners.
Step 1: Remove the dust collector lid and pull out the container, and underneath it you'll see the brush mount.
Step 2: Find the locks on the sides of the brush β usually plastic latches or screws. Xiaomi Mi Robot Vacuum 2 and later uses a quick-removal mount: press the lever on the side and pull the brush up.
For models with screw mounting (for example, Dreame) D9 viomi SE):
- Unscrew the two screws with a cross screwdriver (usually hidden under rubber plugs).
- Take care of the sleeves and remove the sleeves (if any).
- Pull the brush with the axle β it can be removed separately or be part of the mechanism.
In some vacuum cleaners (for example, Xiaomi Mi Robot Vacuum-Mop 2 Lite), the main brush is fixed by a spring mechanism.
1. Press the plastic "ears" on the sides of the brush.
2. Pull it on yourself, keeping your ears pressed.
3. Remove the axle from the grooves.What if the brush is boiling?
After the removal, check:
- π Drive belt β it should not be stretched or cracked.
- βοΈ Axis bearings - when rotating there should be no creak or backlash.
- π§Ή Brushes β if they roll or break down more than 30%, it is time to change the brush.
Features of turbo brushes (for models with enhanced cleaning)
Xiaomi premium vacuum cleaners (e.g. Mi Robot Vacuum-Mop 2 Pro, DreameBot) X30) They're equipped with turbo-brushes with reinforced drive, and they're more complex, so dismantling requires care.
Key differences between turbo brushes:
- π They are attached not only to latches, but also on metal axes with bearings.
- β‘ Have a separate drive mechanism, which can be damaged by careless removal.
- π οΈ Often require adjustment after installation (e.g. belt stretching).
Instructions for turbo brushes:
- Unscrew the two screws on the ends of the brush (they can be hidden under decorative stubs).
- Carefully remove the plastic casing, under which the drive belt is hidden.
- Reduce the tension of the belt by moving the tension roller to the side.
- Pull the brush with the axle, holding it by the metal bushes (do not pull the bristles!).
After the removal, check:
- π§ Belt condition β if stretched, it needs to be replaced (part number is usually listed in the manual).
- π’οΈ Lubrication of bearings - in its absence, the brush will overheat.
β οΈ Attention: In DreameBot models L10 and Xiaomi Mijia 1T The turbo brush has an electronic speed sensor, so don't touch its contacts when disassembling, which can cause calibration errors.
5. Cleaning and maintenance of brushes: how to extend their service life
Remove brushes is half the battle, and to make them last longer, they need to be cleaned and greased properly.
Hair and thread removal:
Use scissors or pliers to cut the hair off the axis.
- For hard-to-reach places, a toothpick or needle is suitable.
2.Sink:
- Wash your brushes in warm soapy water (no more than 40).Β°C).
For disinfection, add vinegar (1 tbsp. spoon per liter of water) or citric acid.
Do not use aggressive detergents β they corrode plastic.
Lubricant:
After drying, apply the silicone lubricant to the axle and bearings.
- It's good for metal axes. WD-40, But don't overdo it, the excess attracts dust.
Drying:
Dry your brushes in the air for at least 12 hours (do not use a hair dryer or battery).
Before installation, make sure that there is no moisture left on the parts.
The frequency of service depends on the intensity of use:
| Type of brush | Cleaning. | Replacement | Signs of wear and tear |
|---|---|---|---|
| Side brush. | Every 1-2 weeks | Every 6-12 months | Broken bristles, backlash axles |
| Main (roller-brush) | Every 3-4 weeks | Every 12 to 18 months | Rolled bristles, creaking |
| Turbo brush. | Every 2 weeks | Every 9-12 months | Overheating, uneven rotation |
If the brushes are worn out, do not skimp on replacement - the use of damaged brushes increases the load on the engine of the vacuum cleaner and reduces its service life by 20-30%.
π‘
Regular brush cleaning not only improves the quality of cleaning, but also reduces the energy consumption of the vacuum cleaner by 10-15%, since the engine does not have to overcome the resistance of the mechanism clogged with garbage.
6. Common mistakes and how to avoid them
Even experienced users sometimes make mistakes when removing brushes that lead to breakages, and here are the most common ones and ways to prevent them:
1. too much effort in removal:
Problem: Plastic latches break or axle bends.
- Solution: If the brush doesn't respond, check if all the locks are pressed. Use it. WD-40 squirt.
Loss of small details:
Problem: Springs, rubber seals or cogs fall out.
Solution: Work on a light surface and take pictures of the disassembly process.
Incorrect assembly:
Problem: The brush rotates backwards or is not fixed.
Solution: Check the polarity (some models only have brushes in one position).
Ignoring lubrication:
Problem: After 1-2 months, the brushes begin to creak.
Solution: After each cleaning, apply silicone lubricant to the axle.
Cleaning by abrasive means:
Problem: The bristles get tough, the plastic gets turbid.
Solution: Use only mild detergents (such as dishwashing).
If the vacuum cleaner produces an error after assembly (e.g., Error 9 or Brush stuck), check:
- π Is the drive belt properly connected (for turbo brushes).
- π Does the direction of rotation of the brush coincide with the marks on the body.
- π± Update the vacuum cleaner firmware β sometimes errors are caused by software bugs.
7.When to contact the service: signs of serious malfunctions
Not all brush problems can be solved by yourself, and if the vacuum cleaner continues to work incorrectly after cleaning and replacing, it may be a mechanical or electronic failure.
1. The brush does not rotate at all, but the engine hums:
Possible causes: the drive motor burned or the belt broke.
2. The vacuum cleaner will give an error of Error 5 or Error 10:
- It could mean a failure of the speed sensor or a closure in the brush's power circuit.
3. The brush rotates in jerks, even after replacement:
- Reason: wear of the shaft bearings or problems with the control unit.
4. Extraneous sounds (screaming, knocking) when working:
- Possible cracks in the body of the gearbox or the entry of a foreign object into the mechanism.
The cost of repairs in the service center Xiaomi or partner workshops:
| Type of malfunction | Cost of repair (β½) | Duration of repairs |
|---|---|---|
| Replacement of the drive motor of the brush | 1 500β2 500 | 1-2 days |
| Repair/replacement of gearbox | 2 000β3 500 | 2-3 days |
| Diagnostics of the electronic unit | 500β1 000 | 1 day |
If your vacuum cleaner is warranty, do not disassemble it yourself - this will void warranty obligations. Contact the official service center (the list can be found on the Xiaomi website by model number).
