How to properly clean the roller of the Xiaomi vacuum cleaner: disassembly, washing and care

The brush roller is a key element of Xiaomi’s robot vacuum cleaner that directly affects cleaning quality. Over time, it is wound with hair, thread, animal hair, and dust and small debris accumulate in the bristles. If you do not clean the roller regularly, the vacuum cleaner begins to collect dirt less, make extraneous sounds or even block the rotation of the brush. In this article, we will discuss how to properly disassemble, wash and clean the roller on Xiaomi Mi Robot, Viomi, Dreame and others to prolong the life of the device and maintain its effectiveness.

Many users make cleaning mistakes, such as using sharp objects to remove windings, washing the roller in hot water, or drying it in direct sunlight, which can cause the bristles to deform, damage bearings, or even the motor of the brush to fail, and we will tell you which tools and tools are safe to use, how often to clean and what to do if the roller jams or starts to creak.

Why Xiaomi’s Vacuum Roller Needs Regular Cleaning

A brush roller is a rotating piece with rubber blades or bristles that picks up dust and debris from the floor, directing them into a dust collector, and it is wound on during cleaning:

• 🧵 Hair (human and animal)
• 🧶 Threads, pile from carpets and clothes
• 🧹 Small garbage (buttons, paper clips, pieces of paper)
• 🐾 Wool and down (especially important for pet owners)

If you do not remove these contaminants in time, the following problems arise:

• ⚠️ Decreased cleaning efficiency - the roller ceases to fit tightly to the floor, passing dust.
• ⚠️ Increased noise – the wound hair rubs against the body, creating a creak or hum.
• ⚠️ Overheating of the engine - a jammed roller makes the engine work with overload.
• ⚠️ Breakage of bearings - dirt and moisture penetrate the mechanism, accelerating wear.

The manufacturer recommends cleaning the roller after every 3-5 cleaning (or more often if there are animals in the house).However, many users forget this until the vacuum cleaner begins to “catch up.” On Xiaomi Mi Robot Vacuum-Mop 2 Pro and DreameBot D9 models, a roller filled can cause a “Brush Error” (code 02 or 05), which blocks the device from working.

Preparation for cleaning: what will be needed

Before you start cleaning, prepare the necessary tools and tools. Do not use hand-held items that can damage the bristles or the body of the roller (knives, scissors, metal brushes).

• 🔪 Plastic scraper (or old bank card) – for careful removal of windings.
• 🧼 Soft toothbrush - to clean the bristles from dust.
• 💧 Warm water (not above 40)°C) and neutral detergent (e.g. dishwashing liquid).
• 🧻 Microfiber cloth or paper towels - for drying.
• ⚙️ Screwdriver (if disassembly of anchorages is required).

For models with rubber blades (for example, Xiaomi Mi Robot Vacuum-Mop P), you may additionally need silicone lubricant to treat the bearings after washing. Do not use WD-40 or other aggressive compounds - they corrode rubber!

⚠️ Warning: Never immerse the roller in water with bearings or electrical contacts (if any) that will lead to corrosion and short circuit. L10s Ultra) washable only removable case.

Step-by-step instructions: how to remove and disassemble the roller

The process of removing the roller may vary depending on the model of the vacuum cleaner. We will consider a universal algorithm suitable for most robots Xiaomi, Viomi and Dreame. If your model has features (for example, quick-clamp mount), refer to the manufacturer's instructions.

1. Turn off the vacuum cleaner and remove the vacuum collector, make sure the device is not connected to the charging station.
2. Turn the robot over and find the roller mounts: 🔄 Two plastic fixtures on the sides (pushed inside). 🔧 Screws (on older models, for example, Xiaomi Mi Robot) 1S). 🔗 Quick-clamp mechanism (on new models, for example, DreameBot) D10 Plus).

Remove the roller by pulling it on or up (depending on the design).Some models need to first remove the side covers.

Disconnect the bearings (if they are removable). To do this, carefully pull the roller to the sides - the bearings must remain in the grooves of the case.

If the roller is not removed, check if the wound debris blocks it, in which case, remove the visible contaminants first, and then try again.

How to Remove Wrapped Hair and Garbage Without Damage

The most common problem is the hair wrapped tightly around the axis of the roller, and if you just pull it, you can damage the bristles or tear the rubber blades.

1. With scissors or scrapers, cut the winding along the axis of the roller. Don't try to cut across, it can deform the bristles.
2. Remove large pieces of garbage with your hands or tweezers. If your hair sticks to rubber, moisten it with warm water for 1-2 minutes.
3. Clean the bristles with a toothbrush soaked in soapy solution, move from center to edge so you don't clog the dirt deeper.
4. Wash the roller under running water, avoiding moisture on the bearings. If they are removable, clean them separately with a dry cloth.

Washing algorithm:

1. Dial in the basin of warm water and add 1-2 cap of detergent.
2. Immerse the roller in water for 10-15 minutes, rotating it periodically for better washing.
3. Wash under running water, removing the residue of foam.
4. Shake off the water and dry the roller vertically (for example, put it on a towel bristles up).

Do not dry the roller with a hair dryer or battery, which can lead to uneven shrinkage of materials. The optimal drying time is 12-24 hours. If you are in a hurry, use the fan at the minimum speed (at least 50 cm away).

What to do if the roller creaks or does not rotate

If after cleaning the roller began to creak, jam or rotate in jerks, the problem may be:

• 🔧 Bearings - dirt got or lubricated washed.
• 🧲 Magnetic sensor (on models with automatic pressure adjustment brushes).
• ⚡ Electric drive (if roller with motor, as in DreameBot) W10).

Instructions for removing squeak:

1. Take the bearings off and test them for backlash. If they're tight, clean them with a dry cloth.
2. Apply 1-2 drops of silicone lubricant to the bearing axis. Do not use oil-based oils!
3. Check if the trash has fallen into the grooves of the roller's mount, clean them with a toothpick.
4. If the creak remains, the sleeves of the roller may be worn out - in this case, replacement will be required.

On electric brush models (e.g. Xiaomi Mi Robot Vacuum-Mop 2 Ultra), the cause of a malfunction may be a wire break or engine breakdown, in which case it is better to contact the service center, as self-repair requires soldering work.

How to extend the life of the roller: prevention and care

To lessen the need for deep cleaning, follow these guidelines:

• 🧹 Remove large debris from the floor before running the vacuum cleaner (clips, wire, toys).
• 🐕 Regularly comb pets – this will reduce the amount of hair on the floor.
• 🔄 Use the "Sweep Only" mode on long-pile carpets (if any in your model).
• 🛒 Replace the roller with an anti-winding model (for example, DreameBot) Z10 Pro is equipped with a brush with self-cleaning bristles).

It is also useful to treat the bristles once every 2-3 months with antistatic (for example, spray for furniture), this will reduce the adhesion of dust and hair. For rubber blades, you can use rubber air conditioning (sold in car stores) to prevent cracking.

If you notice that the bristles have started to "bald" or rubber blades have lost elasticity, it is time to replace the roller. The average life of the original Xiaomi roller is 6-12 months with heavy use. The cost of replacing is from 500 to 1500 rubles depending on the model.

💡

Regular cleaning of the roller not only improves the quality of cleaning, but also prevents breakage of the brush engine, which costs 3-5 times more expensive than the roller itself.
