Disassembly of the vacuum cleaner Xiaomi Deerma: a step-by-step guide with photos and tips from experts

Xiaomi Deerma vacuum cleaners have gained popularity due to a combination of power, compactness and affordable price. However, even the most reliable equipment requires maintenance: cleaning filters, replacing brushes or repairing after falls. If you are faced with loss of traction, strange noises or a complete failure of the device, disassembly can be the first step to diagnosing the problem.

But before you start screwdrivers, it's important to understand that the design of Deerma is different from the classic vacuum cleaners. There are no usual latches under plastic panels, and improper exposure to the case can lead to cracks or damage to the dust container. This article will help disassemble the device without consequences, keeping all seals and mounts intact. CM600, VC20 and DX700 — most common in 2023-2026.

⚠️ Critical: If your vacuum cleaner is still warranty, disassembly will cancel it. Xiaomi official service centers in 90% of cases refuse repair after self-intervention.

Preparation for disassembly: tools and security measures

You won’t need a professional toolkit to disassemble Xiaomi Deerma, but you won’t need some tools, and the main difficulty lies in hidden latches and fragile plastic elements that are easy to break with excessive effort.

Here's the minimum set:

• 🔧 Screwdriver cross (PH2 — corpus)
• 🔧 Plastic blade or mediator (to separate panels without scratches)
• 🔧 Tweezers (to extract small parts, such as sealing rings)
• 🧲 Magnetic mat or bowl (so as not to lose screws)
• 📸 Smartphone (for photographing the dismantling stages - useful when Assembly)

⚠️ Warning: Never use metal blades or knives to separate panels! Deerma body is made of impact-resistant ABS-If the latch doesn't lend itself, check if all screws are twisted - often users miss 1-2 mounts under the stickers.

Before the start of the work:

1. Disconnect the vacuum cleaner from the network (if it is a network model) or remove the battery.
2. Make sure the dust collector is empty – debris can get into the engine during disassembly.
3. Label the screws as they are removed (e.g., “top cover”, “handle”) – this will save hours when assembled.

💡

If the screw doesn't twist, don't use excessive force. WD-40 Or alcohol and wait 5-10 minutes, and 80 percent of the time, it helps to avoid a slime break.

Disassembly of the body: remove the upper and lower panels

So, the most important part of this is to disconnect the main body panels. CM600 and VC20 The algorithm is similar, but there are nuances in the location of the latches.

Step-by-step:

1. Turn the vacuum cleaner upside down. Find 4 screws under the rubber legs (they need to be carefully tucked with a spatula).
2. Unscrew the screws and remove the bottom cover, and there are 2 more screws underneath that hold the engine.
3. Return the vacuum cleaner to its normal position. On the back wall (on the handle side), find 2 hidden screws under decorative plugs.
4. Carefully separate the upper and lower parts of the body, starting with the latches near the dust collector. Use a plastic blade, leading it along the seam.

⚠️ Critical detail: the model Deerma DX700 There's an extra latch under the power button, and if you don't press it from the inside with a screwdriver, the body won't disconnect, and that's what caused 30 percent of the devices to break when they disassemble themselves.

After removing the top panel, you will see:

• 🔋 Battery (in wireless models)
• 🌀 Engine with turbine
• 🔄 Filter system (HEPA and pre-cleaning)
• 📶 Printed board with control buttons

Battery Removal (for wireless models)

The battery is one of the most vulnerable parts of Xiaomi Deerma. Over time, it loses capacity, swells up or refuses to hold the charge. If your vacuum cleaner starts to work less than 10 minutes from the battery, replacing it can return the device to its previous power.

How to remove the battery:

1. Disconnect the power plume from the board (usually it is fixed with a small connector).
2. Unscrew 2 screws that attach the battery to the body.
3. Carefully tuck the battery with a spatula - it can be glued to the body with bilateral tape.

⚠️ Attention: if the battery is swelling (as seen from the deformation of the case), do not puncture it! Lithium-ion batteries can ignite if damaged:

• Place the vacuum cleaner in a non-combustible container (such as a metal pelvis).
• Take it to a battery recycling center or service center.

Dismantling of engine and filtration system

The engine is the heart of a vacuum cleaner, and disassembling it requires special care. 60 percent of the power loss is due to a clogged filter. HEPA Or wear and tear of the engine brushes. Before you disassemble the engine, check:

• 🌀 Cleanliness of the pre-filter (wash under running water once every 3 months)
• 🔍 Integrity of sealing rubber bands (cracks lead to loss of suction)
• 🔊 Absence of foreign sounds (squeaking or hum indicates wear of bearings)

Instructions for engine extraction:

1. Disconnect the duct leading from the dust collector to the turbine (usually mounted on the latch).
2. Unscrew the 3 screws that lock the engine compartment.
3. Carefully remove the engine along with the turbine, do not pull the wires!
4. Disconnect the power connector from the control board.

Critical information: the model Deerma DX700 When disassembling, do not lose the heat paste between the radiator and the engine body - its absence will lead to overheating.

To clean the filters:

• Pre-filter (net) wash with warm water and soap, dry for at least 24 hours.
• Filter HEPA Replace or replace the recommended interval every 6 months).
• The carbon filter (if any) is not washed - only a replacement!

💡

If after cleaning the filters power is not restored, the problem may be in the wear of the engine brushes. their replacement is cheaper than buying a new engine (about 800-1500 rubles. against 3000-5000 rubles.).

Diagnostics and repair of management board

The control board is responsible for adjusting the power, charging the battery and protecting against overheating. If the vacuum cleaner doesn't turn on, spontaneously turns off or doesn't respond to buttons, the problem can lie here.

Typical board malfunctions:

• 🔥 Burnt resistors or capacitors (seen from blackened areas)
• 💧 Oxidation of contacts (especially after moisture is ingested)
• 🔌 Lane detachment (cracks on the board)

For diagnosis:

1. Carefully inspect the charge under the magnifying glass.
2. Call the power chain multimeter (the resistance between the battery contacts and the chip should be close to 0).
3. Check the fuse (usually located near the power connector).

⚠️ Note: If you do not have experience with squashing SMD-The components, the board repair is better entrusted to a specialist. Incorrect soldering can lead to a short circuit and complete failure of the device.

Cleaning the vacuum cleaner: avoidable mistakes

Assembly is often more difficult to disassemble, and the main mistake is the incorrect installation of seals, which leads to a loss of suction power.

Assembly order:

1. Install the engine and fix it with screws (do not pull!).
2. Connect all connectors to the control board (check polarity!).
3. Place the sealing rings on the filters - they should lie flat, without torsion.
4. Collect the body starting at the back (on the handle side), and snap the front panel.
5. Twisting the screws in reverse order, starting with the bottom cover.

⚠️ Warning: after assembly, be sure to check the vacuum cleaner for leakage. Bring your hand to the joints of the body when the engine is running - if you feel the air flow, the seals are installed incorrectly.

Post-assembly test:

• 🔋 Check battery charging (the indicator should burn red when connected to the network).
• 🌀 Make sure the power regulator is running smoothly, without jumps.
• 🔊 Listen to the sound of the engine - it should be smooth, without creaking.

Filter density.

2. Integrity of sealing rubber bands.

3. Absence of foreign objects in the duct.-->

Frequent breakdowns and how to avoid them

Analysis of the service centers shows that 70% Xiaomi Deerma breakdowns are due to improper operation.-5 Problems and ways to prevent them:

Table of typical malfunctions:

How to prolong the life of a vacuum cleaner:

• 🧹 Clean filters after every 5th use (or more often if cleaning in dusty rooms).
• 🔌 Use only the original charger – cheap analogues reduce battery life by 40%.
• 🚫 Do not store the vacuum cleaner in wet rooms (bathroom, balcony) - this leads to corrosion of contacts.
• 🔄 Once a year, disassemble and lubricate the engine bearings with silicone lubricant.
