Xiaomi's wet-cleaning robots are real home assistants, but their water container needs special care. If you leave the tank wet after cleaning, you quickly get an unpleasant smell inside, and mold or limestone forms on the walls. Not only does it shorten the life of the device, but it can also harm your health: mold spores spread through the air during the next cleaning.
Many users make the same mistake: just pour water out of the tank and put the robot on charge, believing that this is enough, but natural drying in a closed container takes up to 48 hours, during which time moisture manages to create the perfect conditions for bacteria. In this article, we will discuss how to dry the tank quickly and efficiently using improvised tools and special accessories.
Why you can’t ignore the drying of the container
The humid environment inside the water tank is a breeding ground for microorganisms, and even if you use distilled water or special detergents, the risk of mold is still there.
- 🦠 Bacteria reproduction: Within 24 hours, colonies of microbes are formed in a wet container, which will be distributed on the floor the next time you clean.
- 🍄 Mold on seals: Rubber gaskets and filters are covered with a black coating, which is difficult to remove without special means.
- 💧 Corrosion of metal parts: In some models (e.g. Dreame) W10) there are metal elements that rust from constant moisture.
- 👃 Persistent smell: The smell of mustyness penetrates the plastic and persists even after washing.
Xiaomi manufacturers have indicated in the instructions that the container should be dried after each use, but they do not explain how to do it correctly. Meanwhile, just leaving the tank in the air is not enough - active ventilation is required.
⚠️ Warning: If your robot vacuum cleaner smells of mold, don't use bleach or aggressive detergents.They can damage the plastic and leave toxic fumes that will spread during cleaning. Instead, use vinegar solution (1:1 with water) or hydrogen peroxide.
Ways to dry the container: from fast to deep
The choice of method depends on how much time you have and what tools are available. We tested 5 methods and evaluated their effectiveness:
| Method | Time to dry | Required funds | Efficiency |
|---|---|---|---|
| Natural air drying | 24-48 hours | — | ⭐⭐ (low-key) |
| Drying by a hairdryer | 10-15 minutes | Cold-air hair dryer | ⭐⭐⭐⭐ (high-pitched) |
| Use of silica gel | 4-6 hours | silica gel packets or rice | ⭐⭐⭐ (middle-class) |
| Ultraviolet lamp | 30-60 minutes | UV lamp for disinfection | ⭐⭐⭐⭐⭐ (maximum) |
| Microwave drying (for removable parts only!) | 2-3 minutes | Microwave, paper towels | ⭐⭐⭐ (Medium, risk of deformation) |
Important: Never dry the container as assembled, disassemble it into its component parts (lid, tank, filter, if any) and speed up the process and prevent moisture from accumulating in hard-to-reach places.
Step-by-step: how to dry the container with a hairdryer
This is the fastest and safest method, if you do it right, you'll need a dryer with a cold air mode (hot can warp plastic).
Dump all the water from the container
Remove the cover and sealing gums
Wash the tank with warm water without detergents
Wipe the available surfaces with a paper towel.-->
- Take the container apart. Most models (Mi Robot Mop 2 Pro, Dreame Z10 Pro) have the lid and the tank detached without tools, and if you have a removable filter, remove it.
- Point the dryer at a 45° angle to the inside of the tank. Keep it 15 to 20 cm away so you don't overheat the plastic. Pay special attention to the corners and joints.
- Dry each part separately: first the tank (2-3 minutes), then the lid and seals (1-2 minutes). periodically shake the container so that moisture drains from the walls.
- After drying, collect the container and leave it in the air for 10-15 minutes, which will help to evaporate the remaining moisture in the microcracks.
If your dryer doesn’t have a cold air mode, use the minimum temperature and keep it at a greater distance (30–40 cm).
⚠️ Warning: Do not dry the electronic components of the robot vacuum cleaner (for example, if water hit the control board).In this case, immediately disconnect the device from the network and contact the service center.
How to use silica gel or rice to absorb moisture
If you don't have a hair dryer or a UV lamp, absorbents will come to the rescue. Silicagel (the shoestring bags) absorbs moisture at 40% of its weight, and rice is an affordable alternative.
- 📦 Place the container in a sealed container (e.g., a plastic box with a lid).
- 🌾 Sprinkle around it 2-3 bags of silica gel or 100-150 g of dry rice.
- ⏳ Close the lid and leave it for 4-6 hours. To speed up the process, you can periodically shake the container.
- 🔄 After drying, remove the absorbent and ventilate the tank for 10-15 minutes.
Silica gel can be bought in household goods stores or ordered on AliExpress (look for "moisture absorber"). Its advantage over rice is reusable: it is enough to dry the bags in the oven at 100 ° C for 1-2 hours.
💡
Store silica gel in a sealed jar - it is useful not only for a robot vacuum cleaner, but also for drying shoes, phones or documents after flooding.
Ultraviolet disinfection: killing bacteria and mold
The UV lamp not only dries, but it also kills up to 99.9 percent of microorganisms, which is true if the container has already got an odor or visible plaque, any UV lamp is suitable for disinfection (for example, Xiaomi Mi Portable UV Sterilizer).
- Wash the container with warm water with a mild detergent (such as dishwashing liquid).
- Place parts of the tank on a flat surface (for example, on a table covered with white cloth to reflect UV rays).
- Turn on the lamp and point to the container from a distance of 10-15 cm. the processing time is 30-60 minutes (depending on the power of the lamp).
- After processing, wipe the surfaces with a dry wipe and assemble the container.
UV radiation destroys bacteria DNA and mold spores, but it doesn't remove mechanical contaminants. So be sure to wash the tank before disinfecting!

What not to do: Common mistakes
Some "advice" from the Internet can harm a robot vacuum cleaner, and this is strictly forbidden:
- 🔥 Dry the container in the oven or on the battery.Plastic most Xiaomi models are not designed for temperatures above 60°C – it is deformed or cracked.
- 🧴 Use alcohol or acetone to clean, break down seals and make plastic brittle.
- ☀️ Leave the tank in the sun. Ultraviolet combined with high temperature causes fading and cracking.
- 🧽 Washing a container in a dishwasher, dishwasher detergents are aggressive, and high temperatures will damage plastic.
Also, do not use a vacuum cleaner for drying - the air flow can drive moisture deeper into microcracks, and dust particles will remain inside the tank.
💡
If a persistent smell appears in the container that is not removed by drying, try soaking it for 1 hour in a solution of vinegar (1 part vinegar to 3 parts water), then thoroughly wash and dry.
How often should you dry the container and take care of it?
Manufacturers recommend drying the water tank after each cleaning, but in practice this is not always realistic.
- 📅 After wet cleaning: If you use water, dry the container immediately. If you only sweep, just drain the water (if any) and wipe the tank dry.
- 🔄 1 time per week: Wash the container with warm water with mild detergent, even if you do not use the washing function.
- 🧼 1 time per month: Disinfect the tank with vinegar or hydrogen peroxide (3% solution).
- 🔍 Every 3 months: Check the condition of the sealing gums. If they become sticky or covered with plaque, replace them.
If the robot vacuum cleaner is rarely used (for example, only on weekends), drain the water from the container and dry it after each cleaning. moisture remaining for 2-3 days is guaranteed to lead to the emergence of bacteria.
