How much is the Xiaomi Vacuum Mop 2 charged on the passport?

According to the technical documentation from Xiaomi, the robot vacuum cleaner Vacuum Mop 2 (model) STYJ02YM) equipped with a lithium-ion battery capacity of 3200 mAh and is charged from a base station with a capacity of 10 W. The manufacturer declares the following parameters:

• ⚡ Full charge from 0% to 100%: 3-4 hours (under ideal conditions).
• 🔋 Battery life: up to 110 minutes in dust removal mode and up to 60 minutes with simultaneous floor washing.
• 📉 Recommended discharge level before charging: below 20% (automatic return to base at 15%).

But these numbers are relevant to a new device with factory settings. ±30% – especially if the robot has been in use for more than a year or is charged at low temperatures +15°C).

It is important to consider that the modifications Xiaomi Vacuum Mop 2 Pro and Lite have similar battery characteristics, but may differ in firmware.

Factors affecting charging speed: why does the robot charge longer?

If your Xiaomi Vacuum Mop 2 charges 5-6 hours instead of the stated 3-4 hours, the reasons may be as follows:

• 🌡️ Ambient temperature: at +5°C charging speed drops by 40%, and when +35°C battery can overheat and automatically reduce current.
• 🔌 Charging station quality: Non-original docking stations (especially with AliExpress) often deliver less power (7–8 W instead of 10 W).
• 📱 Robot firmware: in older versions of the software (below) 3.5.8_0040) No charging optimization. Update firmware through the Mi Home app.
• 🔋 Battery wear: After 300 charging cycles, battery capacity decreases by 20–30%, which increases charging time.

Another nuance is the pre-charging mode, and if the robot returns to base after intensive cleaning, its battery can be heated to 40 to 45.°C. In this case, the system will first cool the battery to a safe temperature (+25°C), and then you start charging fully, which can add up to 1 hour to the total time.

⚠️ Warning: If the robot is charging for more than 8 hours or not gaining 100% overnight, this is a sign of a malfunction of the battery or power controller.

💡

Before long cleaning (more than 90 minutes), turn on the option Settings in the settings of the Mi Home application → Battery → This will reduce the suction power by 10%, but extend the operating time by 15-20 minutes.
