🔌 It discharges quickly even in standby mode (loss 20-30% of charge overnight).
⚡ Battery swollen or corrosion marks visible on the body.
🚫 The vacuum cleaner does not turn on or off a few minutes after start-up.
📉 Mi Home app shows Battery Error or Low Voltage error.

2. Original vs Analog: Which is Best for Xiaomi Vacuum?

The main question when buying is to take the original battery from Xiaomi or a compatible analogue from third-party manufacturers.

Criteria	Original battery	Quality analogue
🔄 Compatibility	100% guarantee, no firmware issues	You may need to reset the vacuum cleaner settings
📦 Assemblance quality	Protection against overheating, bloating, short circuit	Depends on the brand (there are reliable and dangerous options)
💰 Price.	The road is 1.5-2 times (from 3000 to 8000) ₽)	Cheaper (from 1500 to 4500) ₽), but risk getting caught up in a fake
⚡ Capacity	Standard (e.g. 2600mAh for Mi Robot) 1S)	You can choose an enlarged one (for example, 3,500 mAh instead of 2600)
🛠 Guarantee	6-12 months (official dealers)	3 months to 1 year (at vetted sellers)

Our verdict is that if you have a budget, you can take the original, which is a guarantee of safety and longevity, but if you are willing to take the risk, quality analogues (for example, from Baseus, Remax or Patona) can work just as well if you use it properly.
