How to remove the wheel from the vacuum cleaner Xiaomi: instructions with photos and videos

Xiaomi vacuum cleaners are some of the most popular home assistants, but even they require periodic maintenance. One of the common problems is jamming or wear of the wheels that prevent the device from moving normally. Removing the wheel from the Xiaomi vacuum cleaner seems to be an easy task, but in practice many people face difficulties, from sour mounts to the risk of damaging plastic parts. In this article, we will analyze the step-by-step dismantling algorithm for different models (including Mi Robot Vacuum, Dreame and Viomi), list the necessary tools and warn of typical errors that lead to breakage.

It's important to understand that the design of the wheels on Xiaomi vacuum cleaners differs depending on the generation and series. For example, in budget models (for example, Mi Robot Vacuum-Mop 2 Lite) uses a simple axle with a latch, and in premium ones (for example, DreameBot X30 Ultra) - complex mechanisms with bearings. We will discuss in detail the three main types of mounts and give recommendations for their maintenance. If you have never understood the technique, do not worry: with the right approach, the process will take no more than 20 minutes.

What tools will be needed to remove the wheel

Before you start dismantling, prepare everything you need, and without the right tools, you risk breaking plastic locks or breaking threads, and here's the minimum set that most models will use:

• 🔧 A flat screwdriver (preferably with a thin sting - for licking the latches).
• ⚙️ Cross screwdriver (usually) PH0 or PH1 — wheel-holder).
• 🧲 Magnetic screwdriver or tweezers (so as not to lose small screws).
• 🛠️ Plastic mediator or spatula (for careful separation of parts without scratches).
• 🧴 Silicone lubricant or WD-40 (if the wheel is sour or rotating tightly).

Some models (such as the Xiaomi Mi Robot Vacuum 1S) may require a T5 or T6 torx screwdriver, check out the instructions for your model. If you don't have specialized tools at hand, you can do with improvised means: for example, instead of using a mediator, use a plastic card, and instead of a magnetic screwdriver, use tape to fix the screws.

⚠️ Warning: Do not use metal objects (knives, stitches) to tuck in plastic parts, this will lead to chips and cracks. WD-40 and wait 5-10 minutes.

Also prepare a clean cloth or napkin – after removing the wheel, you will have to clean the axle and bearings from dust and dirt. If you plan to replace the wheel, buy the original part in advance (the articles for popular models are shown in the table below).

Types of tire mounts in Xiaomi vacuum cleaners: how to determine your own

Xiaomi's vacuum cleaner wheel design has evolved over the years, and today there are three main types of mounts, each requiring a different approach, and you can tell the type by the appearance of the wheel and the way it's fixed:

1. Axle latch (budget models) - the wheel is held on a plastic axis with a hold that needs to be squeezed out, typical of the Mi Robot Vacuum 1/1S, Viomi V2/V3.
2. Screw mount (middle segment) - the wheel is screwed with 1-2 screws, often hidden under plugs. Found in Mi Robot Vacuum-Mop 2 Pro, DreameBot D9.
3. The bearing assembly (premium models) is a complex design with a metal axis and glands. Used in the DreameBot X30 Ultra, Mi Robot Vacuum-Mop 2 Ultra.

To accurately identify the type of mount, flip the vacuum cleaner and inspect the wheel:

• 🔍 If you see a plastic tongue on the axis, it is a latch (type 1).
• 🔩 If there are screws (sometimes under rubber plugs) - it is a screw mount (type 2).
• ⚙️ If the wheel rotates smoothly but is not removed by hands and the metal axis is visible, it is a bearing assembly (type 3).

Critical: In bearing-assembly models (type 3), if you don't properly dismantle, you can damage the boulders, which will cause dust to enter the mechanism and quickly wear out. If you're not sure about yourself, you should contact a service center. For types 1 and 2, the risk is minimal, and you can manage yourself.

Step-by-step: how to remove the wheel from the vacuum cleaner Xiaomi (type 1 – latch)

This method is suitable for most budget models, where the wheel is fixed with a plastic latch.

1. Turn the vacuum cleaner off the power and turn it upside down with the wheels. Make sure the battery is not discharged - some models lock the wheels at low charge.
2. Look around the wheel, and you'll see a plastic tongue on the side, and you'll be able to gently tuck it in with a flat screwdriver or a mediator, pulling it aside.
3. Pull the wheel on yourself (along the axis). If it doesn't lend itself, sway slightly from side to side. Don't put too much effort into it, you'd better splash the WD-40 axis.
4. After removing the wheel, examine the axle for dirt or rust, and clean it with a cotton swab dipped in alcohol.

If the wheel is tightly rotated after reverse assembly, check:

• 🔄 Is the slap right (should be heard clicking).
• 🧹 Are there any objects inside the axis (hair, thread).
• 🛢️ Is there enough lubrication on bearings (add silicone lubricant if necessary).

⚠️ Attention: In Viomi models V3 The latch often breaks when the tongue is broken, the wheel will dangle if the tongue breaks, and the mount will need to be replaced: VIOMI-007-WHEEL-CLIP).

💡

If the wheel after cleaning still creaks, apply graphite lubricant to the axle - it lasts longer and does not collect dust, unlike silicone.

Dismantling of screw-mounted wheel (type 2)

The screw mount is more reliable than the latch, but it requires care when unscrewing, and the main difficulty is that the screws are often hidden under plugs or rubber inserts.

1. Turn over the vacuum cleaner and find a rubber plug on the wheel (usually in the center), put it in a flat screwdriver and remove it.
2. Under the plug, you'll see a screw (cross or torx) twist it out, holding the wheel with your hand, and sometimes the axis will scroll.
3. After removing the screw, pull the wheel over you, and if it's not removed, check if there's a second screw on the back.
4. Clean the axle and the thread of the dirt. When reassembling, do not drag the screw - this can warp the thread.

In some models (like the DreameBot D9), the screws can be of different lengths. Remember which screw you screwed from, or take a picture of the process. If you get it wrong, the wheel will dangle or spin tightly.

After assembly, check the back of the wheel: if it wobbles, the screw is not tight enough, but you can not drag it, this will lead to deformation of the plastic and the need to replace the part.

Removal of the bearing wheel (type 3 – premium model)

This type of attachment is the most complex and requires the utmost care: the bearing assembly consists of a metal axis, glands and seals, and improper dismantling can lead to dust entering the mechanism and its failure.

Algorithm of action:

1. Unscrew an external screw (usually a torx T6) on the wheel. It can be hidden under a decorative lining.
2. Remove the locking ring with a compass or a thin screwdriver. Be careful, the ring will spring and may fly out.
3. Carefully pull the wheel on you, holding the axle. If it does not remove, sway slightly from side to side.
4. After removal, inspect the bearings and glands, if they are damaged or contaminated, replacement is required.

Features of models with bearing unit:

• 🛑 Don't use it. WD-40 To clean the bearings, it washes the lubricant. It's better to use a special bearing cleaner (e.g., Muc-Off).
• 🔧 When reassembling, do not tighten the locking ring too tightly - this will increase the load on the bearings.
• 🔄 After replacing the wheel, check its centering - if the axle is set curve, the vacuum cleaner will "take" away to the side.

⚠️ Attention: DreameBot X30 The Ultra bearing unit is integrated with the Hall sensor, which is responsible for controlling the revs. If you damage the wiring of the sensor, the vacuum cleaner will lose the ability to accurately track the distance traveled.

💡

If the wheel rotates with difficulty after assembly, check the axis coaxiality - it should be strictly perpendicular to the body. At the slightest distortion, the bearings will wear 2-3 times faster.

Common Mistakes and How to Avoid Them

Even with the seemingly simple process, many people make mistakes that cause wheels or body parts to break, and here are the most common ones and ways to prevent them:

• 🔨 Using the wrong tools - metal screwdrivers scratch the plastic, and too wide stingers break the latches. Always use plastic mediators or special shoulder blades.
• 💪 Excessive effort - if the wheel is not removed, do not pull it. it is better to disassemble the vacuum cleaner further (remove the bottom cover) to understand the cause.
• 🔄 Tug-tug screws, it warps the threads and leads to backlash. Twisting the screws to a light stop without exerting any effort.
• 🧹 Ignoring axle cleaning - dirt and hair on the axle accelerates wear on bearings. Always clean it with a cotton swab with alcohol.
• 🔧 Loss of small parts - locking rings, springs and cogs are easily lost. Work on a light surface or use a magnetic mat.

Another common problem is that the wiring is damaged when the wheel is dismantled. In some models (for example, the Mi Robot Vacuum-Mop 2 Ultra), the wires from the motion sensor fit to the wheel, if you tear them off, the vacuum cleaner will stop building a map of the room correctly. Before you start work, take a picture of the location of the wires or mark them with a marker.

If after assembly the vacuum cleaner does not go straight or "crawls" to the side, the reasons may be as follows:

• 🔄 The wheel is asymmetrical (check the alignment).
• ⚙️ Damaged bearing (replacement required).
• 📏 Different diameter of wheels (if one wheel is worn more severely).

Maintenance and prevention: how to prolong the life of wheels

To keep the wheels of Xiaomi vacuum cleaner last longer, just follow a few simple rules. The main problems - rubber wear, axis pollution and lubrication drying - are easy to prevent:

• 🧼 Regular cleaning – once a month wipe the wheels with a damp cloth and remove hair/strands from the axle. Use a toothpick for hard-to-reach places.
• 🛢️ Lubrication – apply silicone or graphite lubricant to the axle every 3-6 months (do not use oils based on petroleum products!).
• 🔄 Backlash check – if the wheel is wobbling, tighten the screws or replace the locking ring.
• 🚫 Avoid aggressive surfaces - do not vacuum on long-pile or rough laminate carpets.

If you notice that the wheel is starting to creak or spin tightly, don't delay repairs. In the early stages, the problem is solved by cleaning and lubrication, but if you tighten it will require replacing the bearings or the entire wheel. The average life of wheels in Xiaomi vacuum cleaners is 1.5-2 years with active use, but with proper care, this period can be increased by 1.5-2 times.

For models with rubber linings (for example, DreameBot Z10 Pro) it is useful to treat them every six months with a rubber conditioner (for example, Sonax Gummi-Pflege), which prevents cracking and improves grip on the floor.

💡

If the vacuum cleaner starts to dance in place or move in jerks, check the pressure of the wheels on the floor. Sometimes the cause is not wear, but the wrong calibration of the sensors. To reset the settings, press the Home button for 10 seconds.
