How to open a vacuum collector at the robot vacuum cleaner Xiaomi: detailed instructions with nuances

Xiaomi's robot vacuum cleaners are some of the most popular home helpers, but even they have "weak spots" -- one of them is a dust collector that requires regular cleaning. If you first encounter the need to open a garbage container, the process may not seem obvious: Where to press, how not to break the latch, and what to do if the lid does not respond? In this article, we will analyze all the nuances for different models, from the budget Mi Robot Vacuum-Mop 2 Lite to the flagship DreameBot X30 Ultra.

It's important to understand that mishandling the dust collector can cause locks to break, debris to get into the engine, or even sensors to fail, and not only will we show you how to open the container, but we'll also explain why you should do it regularly, what tools you might need, and what to do if the lid is jammed, and we'll also reveal the secrets to extending the life of the filters and avoiding common mistakes.

If your vacuum cleaner is making a mistake like "Error 5" (clogged container) or just getting worse at collecting garbage, it's probably the vacuum bag that's the problem, and then you have detailed instructions with visual cues and life hacks from service engineers.

1. Where is the dust collector of Xiaomi robot vacuums?

In most Xiaomi, Viomi and Dreame models, the garbage container is located at the back of the case, where the power button is located.

• 🔹 Classical models (Mi Robot Vacuum) 1/1S/2, Viomi V2/V3): The dust collector is hidden under a removable cover, which opens by pressing the latch from above.
• 🔹 Hybrid vacuum cleaners with a mop (Mi Robot Vacuum-Mop 2 Pro, DreameBot) D9): The container is divided into two parts, dry garbage and water, and they open in different ways!
• 🔹 Flagships with auto-emptying (DreameBot) X30 Ultra, Viomi Alpha: Here the dust collector is integrated into the docking station, and only a small buffer compartment remains in the robot itself.

To avoid making a mistake, pay attention to the marking on the case: usually next to the cover of the dust collector there is an icon. 🗑️ Or it says "Dustbin." If you're not sure about your vacuum cleaner model, check it in the Mi Home app under Devices» → «Settings» → «About the device».

If you can't find the dust collector, try to inspect the robot with the lights on -- sometimes the latch merges with the body because of the color. At the very least, watch the video manual at the end of the article.

2. Step-by-step instruction: how to open a dust collector

So let's look at the general-purpose algorithm for most models, and if you have a hybrid or a flagship version, go to the specific model section.

Step 1: Take the robot vacuum cleaner with both hands and flip it up with the screen. Make sure it's lying steady -- some models (like the Viomi). V3) They have a rounded body and can roll over.

Step 2. Find a latch or a button on the back cover. It could be:

• 🔘 Flat (pushing down like in Mi Robot Vacuum) 1S).
• 🔘 Speaker (stretched on itself - as in DreameBot) D9).
• 🔘 Double (two buttons on the sides – as in Viomi Alpha).

Step 3: Press or pull the latch with one sharp movement. If the lid fails, do not force - you may be pressing the wrong way. Check if there is a lock from children (in some models it is activated by holding the Home button for 3 seconds).

Step 4. After you click, you'll see the lid lift up.

• 🗑️ Main container (removable plastic box).
• 🧹 Filter HEPA (quintessentially).
• 🔧 Protective grid (in some models).

💡

If the dust collector cover opens tightly, lubricate the latches with silicone lubrication (for example, WD-40 Do not use oil-based oils - they will attract dust and make things worse.

3. Features of opening the dust collector in different models

Not all Xiaomi robot vacuum cleaners are the same. Let's look at the key differences:

If you have a model with an auto-emptying (for example, DreameBot) X30 Ultra, the main dust collector is in the docking station to open it:

1. Make sure the robot is on base.
2. Press the Empty button on the station and hold for 3 seconds.
3. After the beep, pull the container handle on yourself.

4.Typical mistakes and how to avoid them

Even experienced users sometimes make mistakes when working with a dust collector.

⚠️ Attention! Never open the vacuum cleaner immediately after cleaning - wait 5-10 minutes for the dust to settle. Otherwise, a cloud of fine particles will enter the engine and filter, which will reduce the life of the vacuum cleaner.

• 🚫 Force instead of technique: many people break the latches when they try to open the lid with a foot or a screwdriver. If they don't, check if the mechanism is blocked (for example, due to overflow).
• 🚫 Ignoring the filter: Some users only shake out the garbage, forgetting to clean HEPA-This results in a loss of suction power and an error of Error 9».
• 🚫 Washing containers under running water: most models do not have a sealed vacuum.
• 🚫 Using a vacuum cleaner without a filter: this leads to dust entering the turbine and engine failure (repair will cost 60-80% of the cost of a new vacuum cleaner).

Critical error: If after cleaning the dust collector, the robot produces an error "Error 5" (clogged container), but there is no debris inside, the problem is the filling level sensor, which can be reset by holding the "Reset" button on the housing for 10 seconds.

Another common problem is that the lid doesn't close back.

• 🔧 Incorrectly installed filter (check that it sits tightly, without distortions).
• 🔧 Getting garbage in the latches (clean them with a toothpick).
• 🔧 Deformations of plastic (if the vacuum cleaner fell).

5. How to clean the dust collector: tips from service centers

Just shaking out the trash isn't enough. Here's a complete cleaning algorithm that will prolong your vacuum cleaner's life:

1. Remove the container (read above).
2. Shake the trash out of the trash can. For better results, knock on the walls of the container.
3. Remove dust from the filter: 🧹 For the main filter: gently tap them on a hard surface or use a vacuum cleaner with a narrow nozzle. 🧹 For HEPA-Filter: wash under cold water (if it is washable) or replace it with a new one (every 3-6 months).

Clean the internal walls

Check the sealing gums.

AliExpress

Put it back in.

💡

Cleaning the dust collector and filter should be done after every 3-5 cleaning (or more often if there are animals in the house), ignoring this rule leads to a loss of suction power by 30-50% after a month!

For models with wet cleaning function (for example, Mi Robot Vacuum-Mop 2 Pro) additionally:

• 💧 Wash the water tank with warm water and dry it.
• 🧽 Clean the wash cloth (wash by hand without powder so pores don't clog up).
• 🔧 Check the water pump – if it is clogged, the robot will leave a divorce.

6. When replacement of the dust collector or its parts is required

Over time, the plastic in the container wears out, the filters lose their effectiveness, and the seals stop sealing, and here are the signs that it's time to change something:

Where to buy spare parts:

• 🛒 Official stores (Mi Store, Dreame) – original details, but more expensive.
• 🛒 AliExpress – cheaper, but check reviews (look for sellers rated 98%+).

⚠️ When buying filters, pay attention to the article. 1S fits the numbered filter ZNMS17WM, A for DreameBot. D9 — DMF-D9. Non-original filters may not fit in size or pass dust.
