How to insert a brush into a robot vacuum cleaner Xiaomi: instructions with photos and videos

Xiaomi robot vacuum cleaners are smart assistants that save you time cleaning. But even the most reliable appliances require periodic maintenance. One of the most common procedures is replacing or installing side/central brushes that wear out over time, lose their pile or break down. If you're first faced with this task, it may seem difficult to cope with it: it's unclear how to remove an old brush, insert a new one in which direction, and how to fix it correctly.

In this article, we will discuss the step-by-step process of installing brushes for all popular Xiaomi models (including Mi Robot Vacuum-Mop 2 Lite, Dreame D9, Viomi V3 and others), talk about the types of brushes and their features, and warn against typical errors that can lead to a vacuum cleaner breakage. You will learn how to distinguish the left brush from the right one, what to do if the brush is not fixed, and how to extend the life of consumers.

What brushes are in the robot vacuum cleaners Xiaomi

Before you start replacing, it’s important to understand what types of brushes are used in your model, and Xiaomi usually has three types:

  • πŸŒ€ Side brushes are rotating broomsticks on the sides of the vacuum cleaner that jack up the garbage to the central suction hole, come with one-sided (for corners) and two-sided (universal) pile.
  • πŸŒ€ Central brush (roller-brush) - roller with bristles or rubber blades, which is located under the vacuum cleaner and is responsible for deep cleaning of carpets. Z10 Pro) a rubber scraper is used instead of a bristles.
  • πŸŒ€ Turbobrush – reinforced version of the central brush for models with wet cleaning function (for example, Xiaomi Mi Mop 2 Pro.

Side brushes wear out the fastest, and are recommended to be changed every 3-6 months (depending on the intensity of the cleaning); the central brush lasts longer (up to 1-1.5 years), but requires regular cleaning of wound hair and thread. Turbo brushes are usually designed for 2-3 years of use, but their rubber elements can lose elasticity over time.

⚠️ Attention: Not all brushes are interchangeable! for example, side brushes from Mi Robot Vacuum 1S Not suitable for Dreame D9 β€” The diameter of the mount and the length of the pile are different. Always check the compatibility with the article or model of the vacuum cleaner.

Preparation for replacement: what will be needed

Before inserting a new brush, prepare everything you need:

  • πŸ”§ New brushes (original or compatible – check the article on the packaging).
  • 🧹 Soft fabric or napkin for cleaning fasteners.
  • βœ‚οΈ Scissors or tweezers (if the old brush has wound hair).
  • πŸ“Έ Smartphone (to photograph the initial position of the brushes).

Also make sure that:

  1. The robot vacuum cleaner is off and disconnected from the charging station.
  2. The battery is discharged by at least 50% (this will prevent accidental switching on during work).
  3. You work on a flat surface (table, floor without carpet).

πŸ’‘

If you change the side brushes, put the vacuum cleaner on your side so that the wheels do not touch the surface – this will prevent them from accidentally scrolling and damaging the sensors.

Step-by-step: how to insert a side brush

The side brushes are attached to the axes on the side of the vacuum cleaner, and replacing them is the simplest procedure that even a beginner can handle.

  1. Take the old brush off. Take the base of the brush (not the pile!) and pull it aside (on yourself or on yourself, depending on the model.) It should come off the axis effortlessly. If the brush is "feeling," gently spin it left and right.
  2. Clean the axis. Often there is hair, dust, or glue left on the axis (if the brush has been glued) and wipe it with a napkin soaked in alcohol.
  3. Identify the side of the brush. Most Xiaomi models have brushes marked: πŸ”Ή L (Left) - left brush (set from the side where the switch button is located). πŸ”Ή R (Right) - right brush.

If there is no marking, focus on the direction of the pile: it should be tilted towards the back of the vacuum cleaner (to rake up the garbage to the center).

Put on a new brush.

⚠️ Warning: If the brush doesn't rotate after installation or it doesn't rotate with difficulty, it's not installed correctly or the mounting is contaminated.

Installation of the central brush (roller-brush)

The central brush is located at the bottom of the vacuum cleaner under the lid, and it's a little bit more complicated to replace, but it doesn't require any special skills, and the key is to keep the fasteners intact.

Instructions:

  1. Remove the dust collector. Remove the garbage container (usually it is fixed by a latch or a button).
  2. Open the center brush cover. Most models have it mounted on two latches (press them simultaneously and pull the lid up).
  3. Remove the old brush. Carefully pull it up, holding it by the plastic holders on the sides. In some models (for example, the Dreame Bot L10 Pro), the brush is fixed with a screw - it must be twisted out with a screwdriver.
  4. Clean the compartment. Remove the wound hair, threads and dust. Check the bearings -- the little metal balls on the sides -- they should rotate freely.
  5. Set a new brush. Match the grooves on the brush with the guides in the compartment and press until you click. Make sure the brush sits flat and is not skewed.
  6. Close the lid. Click it until you click it.

FAQ: Frequent questions about brushes for Xiaomi

Can I use brushes from other brands (like Roborock) in Xiaomi?
No, Roborock brushes are not compatible with Xiaomi - the mount diameter and the length of the pile differ. The exception is some Dreame models (such as the Dreame Bot Z10 Pro) that can fit certain Xiaomi vacuum cleaners, but this needs to be specified by the article.
Why does the new brush make a lot of noise when working?
Noise can occur for three reasons: the brush is not fully installed (check the fixation); there is debris in the mount (clean the axle); the brush is unoriginal and has an imbalance (replace it with the original); if the noise is not lost, the motor bearing may be worn out, repairs will be required.
How often should I change the central brush if the vacuum cleaner is used daily?
When cleaning the center brush daily, it is recommended to change every 8-12 months, but if there are animals or carpets with a long pile, the service life is reduced to 6-8 months, and regularly inspect the brush for wear of bristles or rubber.
Can I wash the central brush in the dishwasher?
No, the central brush should not be washed in the dishwasher - high temperatures and detergents will damage plastic and rubber elements. The optimal way to clean: Remove the brush and remove the hair manually. Wash under warm (not hot!) water and soap. Dry in the air for at least 24 hours before installation.
What if after replacing the brush, the vacuum cleaner became worse to clean?
Check it out: πŸ”„ The direction of the pile on the side brushes (should scoop up the garbage to the center). 🧹 Cleanness of the central brush (possibly the hair was wound on it). πŸ“‰ Battery level (at low charge, the vacuum cleaner works less efficiently). πŸ› οΈ Settings in the application (possibly silent cleaning mode enabled) If the problem persists, try resetting the vacuum cleaner to the factory.
