How to properly charge the vacuum cleaner Xiaomi: instructions for all models

Xiaomi’s robot vacuum cleaners are some of the most popular home assistants, but even they require proper handling, especially when it comes to charging. How you charge your battery not only affects battery life, but also the life of the device. Many users face problems: the vacuum cleaner does not charge, quickly discharges or refuses to turn on, most often due to improper battery operation or ignorance of the specific model.

In this article, we will discuss how to charge a Xiaomi vacuum cleaner in different series – from the budget Mi Robot Vacuum to the flagship DreameBot and Xiaomi Mijia. You will learn how long it takes to fully charge, how to prepare the device for first use, what mistakes owners often make, and what to do if the vacuum cleaner stopped charging. We will also give recommendations for the care of the battery so that it lasts longer without losing capacity.

If your vacuum cleaner is acting strangely -- like not returning to the dock or showing a charging error -- here's a solution to some of the most common problems, and for those who are just planning to buy, we've compiled a comparison table of charging times for popular models.

Preparation of Xiaomi vacuum cleaner for the first charge

Xiaomi’s new vacuum cleaner requires the right first charge, which is a guarantee of a long battery life. Many people miss this step, considering it optional, but the manufacturer recommends following a few simple rules.

First of all, completely discharge the vacuum cleaner before you first connect to the network. To do this, turn it on and let it work until it shuts down on its own (usually this takes 10 to 30 minutes depending on the model).

• 🔌 Connect the dock to the 220V socket (use only the original adapter!).
• 🤖 Install the vacuum cleaner at the station so that the contacts on the case coincide with the charging contacts.
• ⏱️ Leave the device to charge for at least 5-6 hours (even if the indicator shows 100% sooner).
• 🔋 Repeat the discharge-charging cycle 2-3 times - this will help to "rock" the battery.

Pay special attention to the location of the docking station. It should stand on a flat surface, away from heat sources and direct sunlight. Also make sure that there is enough free space around the station (at least 50 cm in front and 20 cm on the sides), otherwise the vacuum cleaner will not be able to dock properly.

⚠️ Warning: Do not use extension cords or network filters to connect the docking station.Potency surges can damage the battery or control board.

💡

If the vacuum cleaner doesn't start charging the first time, remove it from the station and re-install it. Sometimes the contacts don't come into contact due to dust or an inaccurate landing.

How long does Xiaomi vacuum cleaner charge?

Charging time depends on the model, battery capacity and current charge level, and on average, a full cycle takes between 3 and 6 hours.

Please note that time may increase if:

• 🔥 The vacuum cleaner is charged at high ambient temperature (above 30).°C).
• 🔌 Use of a non-original power adapter.
• 📉 Battery is very worn out (more than 500 charging cycles).
• 🛑 Contacts of the docking station or vacuum cleaner are contaminated.

If your model is charging longer than the time indicated in the table, check the status of contacts and power cable. It is also worth updating the firmware through the Mi Home app - sometimes slow charging is associated with software errors.

How to properly charge the vacuum cleaner Xiaomi: the basic rules

To make the battery last longer, follow these recommendations:

1. Charge after full discharge. Lithium-ion batteries (which are used in Xiaomi vacuum cleaners) do not have a "memory effect", but regular recharging "up to 100%" reduces their life.
2. Don't leave charging for more than 24 hours. Once you reach 100%, turn off the power to the dock (if the vacuum cleaner is not in use for a long time).
3. Store with a charge of 40-60%. If the vacuum cleaner is not used for more than a month, charge it to 50% and disconnect it from the mains. Full discharge or 100% charge when stored harms the battery.
4. Avoid extreme temperatures. Charge at temperatures below 0°C or higher than 40°C can cause irreversible damage to the battery.

Critically, if the vacuum cleaner has not been used for more than 3 months, before charging, let it lie down at room temperature for 2-3 hours.

For models with automatic return to base (for example, DreameBot) L10s Ultra) set up the low charge autocharging option in the Mi Home app, the recommended threshold is 20%, which will prevent full discharge during the cleaning process.

What to do if the Xiaomi vacuum cleaner is not charged?

If the charging indicator does not burn or the vacuum cleaner does not respond to the connection to the docking station, follow the following steps:

1.Check the docking station connection

• 🔌 Make sure the adapter is tightly inserted into the socket and docking station.
• 💡 Check if the power indicator is on at the station (usually a blue or green LED).
• 🔄 Try another adapter (if you have a spare one) or other socket.

2. Clear the contacts.

Over time, dust and oxides accumulate on the metal contacts, wipe them with a dry soft cloth or a cotton swab soaked in alcohol. Do not use abrasive materials!

3.Reset the vacuum cleaner

Press and hold the power button for 10-15 seconds until the device emits an audible signal or restarts. Then set it back to the dock.

4. Check the battery.

If the vacuum cleaner is older than 2-3 years, the battery may have failed.

• ⚡ Charge drops from 100% to 0% in a few minutes.
• ⏳ Working hours decreased by 2-3 times.
• 🔋 The vacuum cleaner does not turn on without connecting to the docking station.

For Xiaomi and Dreame models, the original batteries can be ordered on AliExpress or in service centers, the average cost is 2000-4000 rubles.

⚠️ Warning: If the vacuum cleaner makes unusual sounds (squeaking, crackling) or warms up while charging, immediately disconnect it from the mains! this may indicate short circuit or bloating of the battery.

How to take care of the battery of Xiaomi vacuum cleaner?

The life of the lithium-ion batteries in Xiaomi vacuum cleaners is 300-500 charging cycles. To maximize this period, follow the advice:

• 🔄 Avoid deep discharges. Try to recharge the vacuum cleaner when the charge drops to 15-20%. Full discharge to 0% reduces battery life.
• 🌡️ Watch the temperature. Do not leave the vacuum cleaner on charge in direct sunlight or near heaters. Optimal temperature is 10 to 30.°C.
• 🔌 Turn off the docking station. If the vacuum cleaner has been out of use for more than a week, remove the plug from the socket. Constant connection to the network leads to a "recharge" of up to 100%, which is harmful to the battery.
• 📱 Update your firmware. The manufacturer regularly releases updates that optimize your energy consumption. Check them in the Mi Home app.

For models with removable battery (for example, DreameBot) Z10 Pro) you can purchase a spare battery and alternate its use, which will increase the total time of the vacuum cleaner and reduce the load on the main battery.

If you notice that the vacuum cleaner has become worse to hold the charge, try calibrating the battery:

1. Completely discharge the vacuum cleaner (let it work until it is turned off).
2. Put it on the charger and wait 100%.
3. Disconnect from the network and again discharge to 0%.
4. Repeat the cycle 2-3 times.

💡

Regular calibration (1 every 3 months) helps to reset the battery controller errors and restore an accurate display of charge level.

Frequent errors when charging Xiaomi vacuum cleaners

Even experienced users sometimes make mistakes that shorten battery life or cause breakdowns.

• 🚫 Using non-original adapters: Chargers from other gadgets may not meet current and voltage requirements, leading to overheating of the battery.
• 🚫 Charging immediately after cleaning. If the vacuum cleaner has warmed up while working, let it cool for 15-20 minutes before connecting to the docking station.
• 🚫 Storage at the docking station without use. Many leave the vacuum cleaner on the base "just in case", but a constant connection to the network reduces the battery life.
• 🚫 Ignoring app errors: If the Mi Home shows a charging warning (e.g. Error 10 or Low Voltage), don't delay diagnosis.

Another common problem is that the vacuum cleaner doesn't return to the dock, and it could be related to:

• 📍 Incorrect location of the station (for example, on a carpet with a high pile).
• 🪟 Direct sunlight that interferes with infrared sensors.
• 🧹 Contaminated sensors or wheels.

To avoid such situations, place the dock in a well-lit place (but not under direct sunlight) and regularly clean the vacuum cleaner sensors with a dry wipe.
