Pumping vacuum cleaner Xiaomi: from firmware to upgrade components

Xiaomi vacuum cleaners are some of the most popular cleaning robots on the market, but even they eventually start to work worse: they lose suction power, discharge faster or poorly navigate in space. You can pump such a device both software (through settings and firmware) and hardware (replacing consumables or installing non-original accessories). In this article, only proven methods that actually work on Mi Robot Vacuum, Xiaomi Mijia, Dreame and other brand lines.

Many users mistakenly think that to improve the operation of the vacuum cleaner, it is enough to simply clean the brushes or reset the settings. In practice, there are hidden functions in the proprietary application, alternative firmware with advanced cleaning algorithms, as well as budget upgrades that will increase the time of work on the site. 30-40%. The main thing is not to overdo it with experiments, so as not to lose the warranty or not to disable the device.

In this article, we will discuss:

• 🔧 How to update the firmware of the vacuum cleaner Xiaomi to the latest version (including through the ADB)
• ⚡ Methods to increase battery life without replacing the battery
• 🧹 What accessories will really improve the quality of cleaning (and which ones are a waste of money)
• 📱 Hidden settings in the Mi Home app that 90% of users don’t know about

1. Update of firmware: official and custom versions

Xiaomi's vacuum cleaner firmware is responsible for sensor logic, cleaning algorithms and even power consumption. 2-3 They usually improve navigation or add support for new features (e.g., zoning). However, there are custom firmware from enthusiasts that reveal the hidden potential of the device - for example, increase the suction power at maximum modes or add support for non-original accessories.

To update the vacuum cleaner officially:

1. Open the Mi Home app (or Dreame for the respective models).
2. Go to the device section → Settings → Update the firmware.
3. If the update is available, confirm installation. Importantly, do not interrupt the process and make sure that the battery is at least 50%.

To install custom firmware will require:

• 🖥️ Computer installed ADB (Android Debug Bridge).
• 📁 Firmware file (e.g. from the Xiaomi Community or forum) 4PDA).
• 🔌 USB-cable for connecting the vacuum cleaner to the PC (usually a connector based on the device is used).

⚠️ Attention: Castom firmware can violate warranty and lead to unstable operation of sensors. Before installation, back up the original firmware with the command: adb backup -f backup.ab -apk -shared -all

2. Increased working time: settings and life hacks

Xiaomi’s standard vacuum cleaner battery lasts between 90 and 180 minutes, depending on the model and cleaning mode, but there are ways to extend the battery life without replacing the battery:

Optimization of cleaning modes:

• 🔄 Use Quiet Mode for regular cleaning – it uses 40% less energy.
• 🗺️ Set up zoning in the app so that the vacuum cleaner doesn’t waste charge cleaning unnecessary areas (for example, under the bed if there’s nothing there).
• ⏱️ Start cleaning on schedule when you are not at home – so the vacuum cleaner will not waste energy waiting for commands.

Hardware improvements:

• 🔋 If the battery is running out too quickly, check its status in the Settings menu. → Battery condition: If the capacity falls below 70% of the original capacity, it's time to think about replacing it.
• 🧲 Clean the contacts of the docking station and vacuum cleaner with alcohol - oxidation can increase the charging time on the ground. 20-30%.

💡

If the vacuum cleaner became worse to hold the charge, try to completely discharge and charge it. 2-3 This will help calibrate the battery controller and restore it to the 10% lost capacity.

3. Upgrade components: what really works

Replacing standard accessories with improved ones can significantly improve cleaning efficiency, but not all upgrades are equally useful — some are just marketing ploys.

1. Brushes and rollers:

• 🌀 Silicone rollers instead of standard bristles - better collect animal hair and hair without winding them on a shaft.
• 🧹 Side brushes with elongated villi - increase the area of garbage capture near the walls on the 15-20%.

Filters and containers:

• 🌬️ HEPA-filter H13 (opportunistic H11) — delay 99.97% And you have to notice that you have to change them every time. 2-3 month.
• 🗑️ Larger vacuum collectors (e.g. from third-party manufacturers) – allow less frequent cleaning of the container, but may worsen the balancing of the vacuum cleaner.

3. Wet cleaning accessories:

• 💧 Microfibre wipes with silver coating - prevent the reproduction of bacteria and better absorb moisture.
• 🚿 Water tanks with regulated flow – allow more accurate dosing of water supply on different types of coatings.

⚠️ Warning: Non-original batteries with increased capacity (e.g. 5200 mAh instead of the standard 3200 mAh) can cause the battery to overheat or bloat. If you decide to replace, choose only certified modules with overcharging protection.

4 Hidden settings in Mi Home: what can be enabled

Mi Home hides a number of useful features that aren't displayed in the main menu to activate them:

1. Go to the vacuum cleaner settings.
2. Click on the device icon in the upper right corner 5-7 Once in a row - the Developer Mode will open.
3. Additional options will be available in the menu that appears (the list depends on the model).

Useful hidden functions:

• 🔍 Deep Clean Mode – Increases suction power by 25% but reduces operating time. → Cleaning regimes.
• 📡 Calibration of sensors - helps correct navigation errors if the vacuum cleaner becomes less orientable. → Diagnostics → Sizing.
• 🔄 Continue cleaning automatically, if the vacuum cleaner sat down while working, it will return to base, charge and continue from the same place. → Additionally.

Some models (such as the Xiaomi Mi Robot Vacuum-Mop 2 Pro) have a laser scanned mapping mode to enable:

1. Go to Settings. → Map.
2. Select Scan Type → laser + camera.
3. Save the changes and restart the vacuum cleaner (hold the power button for 10 seconds).

5 Cleaning and Maintenance: How to Get Factory Capacity Back

Over time, the suction power drops not only because of battery wear, but also because of clogs in the system, and regular cleaning can return up to 30 percent of lost performance.

Weekly service:

• 🧲 Clean the main filter and dust collector after each cleaning. Use a soft bristle brush to avoid damaging the mesh.
• ✂️ Remove the wound hair and threads from the shaft of the main brush and side rollers. You can use scissors or a special hook (comes with some models).

Monthly maintenance:

• 🛠️ Disassemble and wash the turbine unit (if permitted by the instructions). For models with wet cleaning function, clean the water tank and the solution supply tubes.
• 🔍 Check the collision and altitude sensors, which can become contaminated, causing the vacuum cleaner to go blind.

Annual servicing:

• 🔧 Replace all consumables: filters, brushes, rubber seals, and even if they look normal, their effectiveness declines over time.
• 🔋 Check the status of the battery. If it swells or deforms, replace it immediately, as it is dangerous for safety.

💡

The most common cause of a drop in suction power is a clogging of the turbine unit or wear of the sealing rubber bands in the dust collector. 200-300 rupees, but returns to 90% factory-productivity.

6. Alternative firmware: pros and risks

Custom firmware (such as Valetudo or modified versions from DustBuilder) allows:

• 📈 Increase the suction power to a maximum (on some models - up to 2500 Pa instead of the standard 2000 Pa).
• 🗺️ Use alternative mapping algorithms (e.g., with multi-floor support).
• 🔓 Unlock manufacturer restrictions (e.g., remove the limit on the number of virtual walls).

However, there are risks:

• ⚠️ Loss of warranty (if vacuum cleaner on warranty, it is better not to experiment).
• 🐞 Possible bugs in the operation of sensors (for example, a vacuum cleaner may start to beat against furniture or build a map incorrectly).
• 🔌 Difficulty rolling back to standard firmware (some models require a soldering iron to restore the loader).

If you decide to install custom firmware, follow this algorithm:

1. Download the firmware from a trusted source (e.g., Valetudo repository on GitHub).
2. Connect the vacuum cleaner to the PC through USB (usually the connector is hidden under the base cover).
3. Launch the installation through ADB Team: Adb sideload firmware.zip
4. Wait until the finish (the vacuum cleaner will restart several times).

⚠️ Note: On models with a processor MT7688 (For example, Xiaomi Mi Robot Vacuum 1S) custom firmware can lead to "bricking" of the device. Before installing, check compatibility on forums.

7 External accessories: what is worth buying

In addition to internal upgrades, there are external accessories that will simplify the operation or expand the functionality of the vacuum cleaner:

Some accessories can be made by yourself, such as a 5 cm-wide strip of tape that is pasted on the floor (the vacuum cleaner doesn't cross it), and an old toothbrush with hard bristles is suitable for brushing.

💡

If the vacuum cleaner is not good at cleaning corners, stick a strip of bilateral tape on the side brushes (with villi outside). 5-7 mm and improves the capture of garbage from the boards.
