How to properly clean the steamer Xiaomi: from scale to filters

Why is cleaning the Xiaomi steamer a mandatory procedure?

Xiaomi steamers (including Smartmi, Viomi and Deerma) have become indispensable cleaning assistants, but their effectiveness depends on the condition of the internal components. Scale, lime plaque and bacterial deposits not only reduce the life of the device, but also reduce the quality of steam, and in some cases can even bring the device down. For example, in models with an aluminum heating element (for example, Smartmi Air Steam Mop P1) scale with a thickness of only 1 mm increases power consumption by 10-15%.

The manufacturer recommends cleaning every 10-15 cycles of use (or every 1-2 months in heavy use). However, few people follow these tips until they encounter problems: weak steam pressure, unpleasant smell or automatic locking of the device due to overheating sensors. In this article, we will discuss how to clean the Xiaomi steamer at home – from basic tank flushing to deep cleaning of the heating element.

Before you start, make sure your model supports disassembly. For example, the Viomi V3 has a removable filter, and the Deerma CM600 requires careful removal of the cover. If you are not sure, check the instructions or use our compatibility table below.

Preparation for cleaning: what will be needed?

Xiaomi doesn’t need professional tools to clean the steamer, but some tools and accessories will make the process much easier.

• 🧴 Acetic acid (9%) or citric acid to remove scale. Do not use hydrochloric acid or aggressive detergents!
• 🧼 Soap solution (better based on household soap) - for cleaning external surfaces and hoses.
• 🧽 Soft sponge or brush - for mechanical cleaning without risk of damaging the coating.
• 🔧 Screwdriver (cross or flat) – for models with removable rear panel (for example, Smartmi Air Steam Mop) S1).
• 💧 Distilled water - for final rinse (prevents re-formation of scale).

If your steamer is equipped with a removable filter (as in Viomi SE), prepare a new filter element in advance or rinse the old one under running water. For models with an integrated ionizer (for example, Deerma CM700), you will need a special tool for cleaning silver electrodes - it can be replaced with a solution of soda (1 tbsp. spoon per 1 liter of water).

⚠️ Warning: Never use abrasive powders or metal brushes to clean the Xiaomi steamer. They damage the non-stick coating of the heating element and can lead to corrosion.

Step-by-step: how to clean the tank and heating element

The main problem with the steamers is scale, which is formed by hard water, and it settles on the TEN (tubular electric heater) and the walls of the tank, reducing thermal conductivity and increasing heating time, and clean it in this sequence:

1. Turn off the device and wait for a full cooling (at least 30 minutes).
2. Pour the remaining water through the drainage hole (if any) or simply flip the steamer over the sink.
3. Prepare a cleansing solution: For low scale: 100 ml of vinegar (9%) per 1 liter of water. For strong scale: 2 tbsp. citric acid per 1 liter of water.

Pour the solution into the tank

Turn off the device.

Wash the tank.

For models with removable TENom (such as Smartmi Air Steam Mop P1 Pro), you can remove the heating element and clean it separately. Carefully remove the scale with a wooden stick or plastic scraper, then rinse under a stream of water.

Pour the cleaning solution into the tank | Turn on the steamer for 5-7 minutes | Leave the solution for 1-2 hours |Wash the tank 3-4 times with clean water | Check the steam pressure after cleaning-->

Cleaning steam nozzles and hoses: remove dirt and bacteria

Xiaomi’s steamer nozzles and hoses come into contact with steam and surfaces, so they accumulate not only mineral deposits, but also bacteria, mold, and models with textile nozzles (for example, ironing clothes) and flexible hoses where water can stagnate are especially vulnerable.

Cleaning instructions:

1. Remove all the nozzles and rinse them under warm water with soapy solution. For hard-to-reach places, use cotton swabs or toothpicks.
2. Blow the hose (if it is removable) with a dryer in cold air mode or simply shake off the water by turning it over.
3. Disinfect: For plastic nozzles: soak in a solution of chlorhexidine (0.05%) for 20 minutes. For textile nozzles: wash in a washing machine at 60°C with antibacterial powder.

Please.

If the hose or nozzles remain unpleasant odor, repeat disinfection with the addition of 1 hour. spoon of baking soda per 1 liter of water. For models with a flavor (for example, Viomi V3 Pro) after cleaning add 2-3 drops of essential oil to the tank to neutralize the smells.

⚠️ Warning: Do not use wire or sharp objects to clean hoses - this can damage the inner coating and lead to leaks on the next use.

Cleaning filters: when and how to change?

The filters in Xiaomi steamers serve two functions: they trap scale particles and soften water. Smartmi and Viomi models typically have removable cartridges that require replacement every 3-6 months (depending on the intensity of use).

• 🔥 Increased water heating time.
• 💧 Weak steam pressure or intermittent serving.
• 🔊 Extraneous noise (hisping, gurgling) when working.

How to Clean or Replace the Filter:

If your model filter is non-removable (for example, in some versions of Deerma), it can be washed by pouring a solution of citric acid into the tank (20 g per 1 liter of water) and turning on the steamer for 10 minutes in maximum power mode. Repeat the procedure 2-3 times if the steam pressure is not restored.

💡

After replacing the filter, the first 2-3 cycles use distilled water – this will extend the life of the new cartridge by 20-30%.

Deep cleaning: dismantling the steamer Xiaomi

If the surface cleaning didn't work and the steamer still doesn't work properly, a partial disassembly is required, a method that is suitable for advanced users, as improper actions can lead to loss of warranty or breakdown.

• 🔧 Are there screwdrivers on the body (in Smartmi models they are usually hidden under rubber plugs).
• 📄 Is the warranty period expired (disassembly cancels the warranty from official dealers).
• 🔌 Is the device disconnected from the network (even in the disassembled state, the capacitors can store charge!).

Step-by-step instructions for disassembly (for example, Smartmi Air Steam Mop S1):

1. Remove the water tank by pulling it up.
2. Turn away 4 screws on the back (they can be under rubber legs).
3. Carefully remove the top cover, do not pull the wires!
4. Remove the heating element and clean it of scale mechanically (plastic scraper) or chemically (soaking in vinegar for 1 hour).
5. Check the temperature sensor – if it is covered with plaque, wipe with alcohol.
6. Collect the device in reverse order, making sure all sealing gums are in place.

For models with an electronic control unit (for example, Viomi V3 Pro) it is not recommended to disassemble the board yourself. If after cleaning the thermal power plant and filters the problem remains, contact the service center - a controller or pressure sensor may malfunction.

How to prolong the life of the Xiaomi steamer?

Regular cleaning is only half the success, so to keep the steamer lasting longer, follow these rules:

• 💧 Use distilled or filtered water – this will reduce scale formation by 80%.
• 🔄 Pour water after each use, especially if you keep the appliance in an unheated room (risk of corrosion).
• 🌡️ Do not turn on the steamer "idle" (without water) - this leads to overheating of the TEN.
• 🔌 Keep the device in an upright position to avoid stagnation of water in the hoses.
• 📅 Keep a "use log" - write down the dates of filter cleaning and cartridge replacement.

For models with self-cleaning function (for example, Viomi V3 Pro) run it at least 1 time per month. the self-cleaning algorithm is usually activated via the menu or by long pressing the power button (exact combination check in the instructions).

If you use a steamer to clean floors with chemical detergents, flush the tank after each cleaning. Residues of detergent can react with metal parts, accelerating corrosion.

💡

The use of distilled water and regular replacement of filters increase the life of the Xiaomi steamer by 2-3 times compared to the operation on hard water without maintenance.

Frequent mistakes when cleaning the Xiaomi steamer

Even experienced users sometimes make mistakes that lead to breakdowns.

1. Use of undiluted vinegar – Concentrated acid corrodes rubber seals and can damage the corrosion-resistant coating of TENS.
2. Cleaning hot steamer – a sharp temperature drop (for example, if you pour cold water into a hot tank) leads to deformation of the plastic.
3. Ignoring filters – a clogged filter increases the load on the pump, which can cause it to burn out.
4. Storage with water in the tank is an ideal environment for the reproduction of bacteria and the formation of mold in the hoses.
5. The use of abrasives - scratches on the TENS accelerate corrosion and shorten the service life.

If after cleaning the steamer began to hiss or whistle, probably there was air in the system. Turn the device on for 1-2 minutes in maximum steam mode to drive out the air traffic jams.

If the device does not turn on at all, check:

• Integrity of the network cable (especially at the base).
• The power of the socket (connect another device).
• Water in the tank (some models are blocked when the tank is empty).
