Clogged filters, dirty brushes or dusty LiDAR sensor

V9 Pro

Many users limit themselves to emptying the garbage container, forgetting about deep cleaning of the turbine unit, sensors and rubber seals. HEPA-The filter reduces its efficiency by 40% after 2 months of active operation.In this article, detailed instructions for cleaning all Xiaomi nodes are provided. V9 Pro, including hidden details not mentioned in the official manual.

We'll take it apart.

• 🔧 Step-by-step disassembling the vacuum cleaner without the risk of damaging the plastic latches
• 🧼 How and how to wash each item (including prohibited detergents)
• ⚠️ Common Mistakes That Shorten the Life of a Robot
• 📊 Preventive care schedule depending on the intensity of use

1.Preparation for cleaning: what will be needed and safety measures

Before you start the dismantling of Xiaomi V9 Pro, prepare the workspace and tools. Robot must be turned off (button) ON/OFF The battery is removed (if you plan to wash the internal parts), which will prevent short circuits if moisture enters.

You will need to:

• 🧴 Soft brush (dental or electronic cleaning)
• 🧽 Microfiber cloth (does not leave a pile)
• 💧 Warm water (not above 40)°C)
• 🧼 Neutral detergent (such as Baby Line or Loc)
• 🔑 Plastic blade (for disassembling latches)
• 🧲 Magnetic screwdriver (cross, size) PH0)

What can't be used:

• 🚫 Abrasive sponges (scratching plastic and LiDAR glass)
• 🚫 Alcohol, acetone, gasoline (destruct rubber seals)
• 🚫 Hair dryer or hot water (deforms plastic parts)
• 🚫 Hard metal tools (will damage latches)

⚠️ Warning: If the vacuum cleaner was in a dusty room (for example, after repair), do not shake off the garbage over an open container - small particles can get into the turbine unit and jam the engine.

2. Cleaning of external elements: brushes, wheels and sensors

Start with the side brush, which collects most of the debris from the walls and furniture, and remove it by pressing the lock on the side, and remove the hair or thread that has wound.

1. Wash the brush under running water.
2. Remove the remains of dirt with a toothpick from the bearing.
3. Dry for at least 2 hours (wet brush breaks faster).

The main brush (roller) requires special attention. Take it off by pulling the levers on the sides, and clean:

• 🧹 Hair and wool – Use scissors or a special removal tool (e.g. Xiaomi Hair Removal Tool).
• 🔍 Bearings - scroll the roller and remove the dirt with a cotton swab.
• 🛑 Rubber blades – wipe with a wet cloth (do not wet completely!).

The wheels are often clogged with dust and hair. Check their mobility: if the wheel is hard to spin, clean the axle of dirt.

1. Remove the wheel by smacking a plastic spatula.


2. Wash the bearing axle and ball with alcohol (only 70% solution!).




3. Lubricate with silicone lubricant (do not use WD-40!).

LiDAR is the most vulnerable element. Never rub it with a dry cloth!

• 🕶️ Special wipes for optics (for example, for glasses).
• 💨 A container with compressed air (keep at a distance of 10 cm).

💡

If the LiDAR sensor is heavily contaminated (dust visible to the naked eye), wipe it with a cotton disc dipped in distilled water, and then dry it for 10 minutes with a dryer in cold mode.

Disassembly and cleaning of the garbage container and filters

The garbage container in Xiaomi V9 The Pro consists of three parts:

1. Main compartment (where the garbage gets into).
2. Cyclone filter (plastic "grid" inside).
3. HEPA-filter (back, under the cover).

Cleaning instructions:

Remove the container by pressing the release button|Throw out the garbage by flipping the container over the urn|Wash the main compartment with warm water with soap|Dry all the details for at least 4 hours|Clean the cyclone filter with a soft brush|Vacuum-washer HEPA-filter (do not wash!)-->

Features of care HEPA-filter:

• 🚫 Don’t wash – it destroys microfibers.
• 🔄 Blow the vacuum cleaner once every 2 weeks.
• 🗑️ Change every 6 months (original artwork. ZNMS04WM).

The turbine unit is the dirtiest place in the vacuum cleaner.

1. Remove the bottom cover (4 screws) PH0).
2. Disconnect the turbine power connector.
3. Remove the block and clean the blades with cotton swabs.

⚠️ Warning: If you hear a whistling or grinding when you're working the vacuum cleaner, it's a sign that a foreign object has hit the turbine.

Cleaning of the wet cleaning system (mop function)

If you V9 Pro equipped with a function of floor washing, pay attention to the water tank and napkin:

• 💦 Water tank - wash after each use to avoid mold. Use vinegar solution (1:10) once a month for disinfection.
• 🧺 Washing by hand at 30.°C with mild powder. Don't use bleach!
• 🔧 Water pump – if the robot has stopped wetting the floor, check the tube for blockages (blow air).

Typical problems of mop function:

• 🚰 Water does not come in - a clog in the tube or a faulty pump.
• 💧 The stains - damaged tank seal (replace with art. ZNMS05WM).
• 🧼 Dilutions on the floor – too dirty napkin or hard water (use distilled).

Cleaning of electronic components: board, sensors and contacts

Dust and moisture can disable the motherboard or the collision sensors, and to clean them up:

• 🔌 Turn off the battery (required!).
• 💨 Blow the board with compressed air (hold the balloon vertically).
• 🧴 Clean the contacts with a cotton swab soaked in isopropyl alcohol (90%+).

The collision sensors (front) are often covered with dust, wipe them with a dry cloth, avoiding pressure. If the robot is "not seeing" the obstacle, check:

1. Integrity of infrared sensors (they must be transparent)
2. The front bumper mounting - it should not hang out.

The charging station contacts also require maintenance.Oxidation can lead to poor contact and a Charging Fault error.

• 🧃 Swallow (to remove oxides).
• 🪄 Alcohol (for final cleaning).

⚠️ Warning: If the robot doesn't turn on after cleaning or flashes red, check if the board connectors are properly connected.

Prevention and maintenance schedule

To Xiaomi V9 Pro has served longer, follow this schedule:

Tips for extending the service life:

• 🔋 Battery – Store the robot with charge 40-60%. Complete discharge or 100% charge reduces battery life.
• 🏡 Room – remove small items (socks, wires) before cleaning to avoid blockages.
• 🌡️ Temperature – Do not use a vacuum cleaner below 5°C or higher than 40°C.

💡

Regular cleaning of the turbine unit and HEPA-The filter increases the suction power of Xiaomi V9 Pro on 30-40% and prevents the engine from overheating.

7.Typical User Mistakes and How to Avoid Them

Even experienced robot vacuum cleaners make mistakes that lead to breakdowns.

❌ "Mine. HEPA-tap-filter" → It destroys its structure. The filter can only be vacuumed or blown through with air.

❌ "I use a household vacuum cleaner to clean the turbine" → A powerful flow of air can damage the blades. Use only a soft brush or cotton swabs.

❌ "I keep the robot on charge all the time" → This reduces battery life. Turn off power after you're fully charged.

❌ "LiDAR cleans with alcohol" → Alcohol corrodes the protective coating. Use only napkins for optics.

❌ "Ignoring errors on the screen" → Codes like Error 10 (a clogged turbine) or Error 12 (a LiDAR problem) require immediate response.

💡

If the robot detects an Error 9 error (a sidebrush problem), check not only the brush itself, but also its motor, often because moisture has been introduced into the contacts.
