The first step is to identify the symptom. Xiaomi vacuum cleaners usually signal problems with audible signals, flashing indicators or error codes on the screen (in models with a display).

• 🔴 Blinking red indicator – battery or charging problem.
• 🔊 The vacuum cleaner beeps 3 times - the turbobrush or the main filter is clogged.
• ⚠️ Mistake "E5" (on robot vacuum cleaners - a problem with the collision sensor.
• 🌀 The brush does not rotate - wear of the belt or motor of the brush.
• 🔋 Does not hold charge - battery wear or controller malfunction.

If the vacuum cleaner does not respond to the switch on button at all, check:

1. Is the power cord connected (for network models)?
2. Is the battery charged (for wireless)?
3. Core and socket integrity.

For accurate diagnosis, use the official documentation for your model. For example, for Mi Robot Vacuum-Mop 2 Pro, error codes can be found in the manual on page 18. If there is no documentation, search the model on the forums (for example, for the model, 4PDA or MIUI Su Su Su Su Su Su).

• 🔌 For network models: Make sure the cable is intact, the socket is working and the plug is tightly inserted. Try another cable (for example, from a laptop with the same connector).
• 🔋 For battery models: Put the vacuum cleaner on charge for 30-60 minutes. If the indicator does not light up, the problem is in the battery or charger.

2. Press the power button for 10-15 seconds.
3. Connect to the power and try to turn it on.

If the reset didn't help, the battery or power controller is likely to malfunction.

1. Disassemble the vacuum cleaner (instructions for popular models - below).
2. Measure the voltage at the battery terminals with a multimeter. The norm for Xiaomi Li-ion batteries is 14.4-16.8 V (for 4 cells).
3. If the voltage is below 12V, the battery needs to be replaced.
