Xiaomi vacuum cleaner does not work: a full analysis of the causes and solutions

Your Xiaomi Mi Robot Vacuum, Mi Vacuum Cleaner or Dreame suddenly stopped turning on, buzzing but not removing, or not responding at all to buttons? This problem is familiar to many owners of smart brand equipment — according to service centers, up to 30% of calls are related to malfunctions that can be fixed on their own. In 70% of cases, the fault is not a breakdown of electronics, but banal clogging, firmware errors or improper operation.

In this article, we will look at all the possible reasons why Xiaomi vacuums may not work, from the obvious (battery dead) to the hidden (collision sensor failure). For each problem, we will give step-by-step instructions with photos, video examples and warnings about typical errors. And if your case is unique, at the end of this article you will find a list of official service centers and tips for choosing spare parts.

Before carrying the equipment for repair (where the diagnosis will take from 1,500) ₽), Take 10 minutes to check our checklist, 8 out of 10 vacuum cleaners can be resuscitated without a soldering iron or a specialist.

1. Xiaomi vacuum cleaner does not turn on: check power and battery

The most common cause of a dead vacuum cleaner is power problems, and start with these steps:

• 🔌 Check the socket and the cable. Connect another socket (like a phone) to the same socket. If it doesn't charge, it's a problem on the network. Try another cable (the original one from Xiaomi has a marking). 5V/2A or 9V/1.5A).
• 🔋 Charging indicator: When connected to the network, the body should light up a red or orange LED (Dreame models) V10 If the indicator doesn't burn, the power supply or contacts are broken.
• 🔄 Reset the battery. Turn off the vacuum cleaner, press and hold the power button for 10 to 15 seconds. Then plug in the charger and try to turn it on. This resets the battery controller.

If the Xiaomi vacuum cleaner does not charge at all, the reasons may be more serious:

⚠️ Attention! Never use power supplies from laptops or other devices to charge a Xiaomi vacuum cleaner, even if the connector fits (19V instead 20V) This causes the controller to fail and the battery to fire.

2.Vacuum hums, but does not remove: blockages and mechanical breakdowns

If the vacuum cleaner turns on, makes sounds, but doesn't move or suck up the garbage, it's mechanical blockages or wear and tear of parts.

1. Look at the main brush. The hair, the threads and the fur of the animals are wound on the shaft and block the rotation. Take off the brush (press the latches on the sides) and clean it with scissors.
2. Check the side brushes. Dreame models often jam because of the large debris. Rotate the brushes with your hand, they should rotate freely.
3. Test the turbobrush (if any) on models with a detergent module (Mi Vacuum-Mop 2 Pro) to check if the water nozzles are clogged.

If the vacuum cleaner does not work after cleaning:

• 🔧 Clog in the duct. Unplug the hose (at the vertical vacuum cleaners) or remove the lid of the garbage can. Blow the tube with a compressor or vacuum cleaner in the opposite direction.
• 🌀 The fan is broken. The sound must be heard when it is turned on. If the sound is intermittent or absent, the engine is defective (replacement is required).
• 🛠️ Wear of the belt of the drive of the brush. 1S) The belt stretches in 1-2 years.

Clean the main brush from hair and threads|

Check the side brushes for free rotation|

Blow the duct (hose or tube)|

Remove and flush HEPA-filter|

Check the turbobrush (if any) for blockages-->

Pay special attention HEPA-A clogged filter not only reduces the suction power, but also causes the engine to overheat, wash it under running water (if the instructions permit) or replace it with a new one (the original is worth it). ~800 ₽).

⚠️ Attention! After washing the filter, be sure to dry it 24 hours at room temperature. A wet filter will short circuit the control board.

3. firmware errors and software failures

Smart vacuum cleaners Xiaomi work on the basis STM32 or ESP8266 If the vacuum cleaner turns on but behaves inadequately (does not respond to the application, drives around, does not build a map), the problem is the software.

Symptoms of programmatic failures:

• 🤖 The vacuum cleaner doesn’t connect to Wi-Fi or permanently loses communication with the Mi Home app.
• 🗺️ Does not build a map of the room or "forgets" saved cleaning areas.
• 🔄 It freezes at the initialization stage (white indicator burns, but does not start cleaning).

How to fix it:

1. Reset the vacuum cleaner. Press and hold the power button for 20 seconds until the light goes out.
2. Update your firmware through the Mi Home app: Device profile → Settings (⚙️) → Firmware update
3. Reset settings. Press Home and Power for 5 seconds (for models with physical buttons).

If Xiaomi vacuum cleaner is not updated through the app, try hand-stitching it through USB-OTG (Guidelines for Advanced Users):

4.Problems with sensors and navigation

Xiaomi vacuum cleaners are equipped with many sensors: laser (LDS), And if one of them fails, the robot will no longer be able to navigate.

Typical symptoms:

• 🤖 Vacuum cleaner travels in circles or moves chaotically.
• 🚫 He sees no obstacles and hits the furniture.
• 📡 He doesn't return to base, loses his signal.

How to diagnose:

1. Clear the lidar (LDS). In models with laser navigation (Mi Robot Vacuum-Mop 2), the lidar glass (the top rotating "turret") should be clean.

If the sensors are physically healthy, but the vacuum cleaner still does not navigate, the problem may be damage to the memory card (in models with saving cards).

Device settings → Map → Reset saved cards

⚠️ Attention! Do not use Xiaomi vacuum cleaner on black or mirrored surfaces (for example, on dark-colored laminate). LDS It doesn’t recognize these coatings, and the robot will go blind».

💡

If the vacuum cleaner doesn't build a map after cleaning the sensors, try moving the dock to another location, and sometimes the problem is interference from the Wi-Fi router or microwave.

5. Xiaomi vacuum cleaner doesn't wash the floor: water module problems

Wet cleaning models (Mi Vacuum-Mop 2 Pro, Dreame) W10) If the vacuum cleaner is running but not washing, check it out:

• 💧 The water level in the tank. The sensor may not work properly if the tank is crooked or contaminated.
• 🔧 The spray nozzles. They get clogged with scale (if you pour tap water.
• 🔋 The water pump, when turned on, you should hear a slight buzzing sound, if you don't have one, the pump burns down.

Instructions for cleaning the water module:

1. Remove the water container and rinse it under running water.
2. Unplug the water supply hose (carefully, effortlessly!) and purify it.
3. Check the sealing ring on the tank - if it is torn, replace (article) MDY-007 For Mi Vacuum-Mop).

If Xiaomi's vacuum cleaner doesn't clean the floor even after cleaning, it could be because the valve malfunctions. Dreame models have a common problem, because the valve sticks because of hard water.

• Disassemble the lower part of the vacuum cleaner (unscrew 4 screws).
• Find the valve (a small black rubber part next to the pump).
• Wash it in a vinegar solution (1:1 with water) and lubricate it with silicone lubricant.

💡

Use only distilled or boiled water for wet cleaning. Hard tap water disables the pump and valves in 3-6 months.

Errors and fault codes: decryption

Xiaomi vacuum cleaners signal problems with beeps and flashing indicators, and below is the error code decoding table for popular models:

Models with a display (Dreame) V11) Errors are displayed as alphanumeric codes:

• E1 — duct-closure.
• E2 — mainbrush.
• E5 — laser-sensor failure (LDS).
• E9 — gyroscope error (calibration required).

If the vacuum cleaner makes a mistake E5 or E9, But the sensors are clean, try resetting to the factory:

At the Mi Home appendix:


Device Profile → Settings (⚙️) → Resetting

7. When to contact the service: complex breakdowns

Not all problems can be solved by yourself. Contact the service center if:

• 🔥 Vacuum cleaner smells like smoke or smoke - it's a sign of short circuit.
• 💥 After a fall or impact is not included (possible breakage of the fee).
• 🔋 Battery swelling or leaking (hazardous to health!).
• 🤖 The vacuum cleaner does not respond to reset and firmware (the controller burned down).

Cost of repair in official Xiaomi services (2026):

Where to repair:

• 🏢 Official service centers. List on the website Xiaomi Russia.
• 🔧 Unofficial workshops, cheaper by 20-30%, but the risk of poor repairs.
• 🛒 Self-replacement of spare parts: parts can be ordered on AliExpress (stuff search) or in Beru/Caspian stores.

⚠️ If the Xiaomi vacuum cleaner is warranty (usually 12 months), do not open it yourself - this will void the warranty obligations.

8. Prevention of breakdowns: how to prolong the life of a vacuum cleaner

Compliance with simple rules of operation will reduce the risk of breakdowns by 60%:

• 🧹 Clean the vacuum cleaner after each cleaning: Clean the main brush of hair| Wash the garbage container| Check the blockage filter| Wipe the sensors with a dry wipe.-->
• 🔋 Charge correctly: Do not leave the vacuum cleaner on charging for more than 24 hours. Use only the original power supply. Once every 3 months, perform a full discharge-charge (for battery calibration).
• 💧 For wet-cleaning models: Use only distilled water. After cleaning, drain the water and dry the tank. Once a month, flush the pump with citric acid (1 tsp per 1 liter of water).

Avoid these mistakes:

• ❌ Cleaning of construction waste (cement, plaster) - it cements the filter and ducts.
• ❌ Use of aggressive detergents – they corrode rubber seals.
• ❌ Storage of vacuum cleaner at a temperature below 0°C - the battery loses capacity.

💡

Regular cleaning of brushes and filters increases the life of the Xiaomi vacuum cleaner from 3 to 5-7 years.
