Operating Xiaomi’s smart appliances requires a careful attention to detail, especially when it comes to basic maintenance like vacuum cleaners. Many owners of Roborock, Viomi and Mijia series of robot vacuum cleaners have difficulty trying to retrieve the garbage container for the first time, because engineers use a variety of fixation systems designed to ensure tightness and secure attachment during operation.
Incorrect actions can lead to breakage of latches or damage HEPA-filter, which will significantly reduce the quality of cleaning and the service life of the device. In this article, we will discuss in detail the mechanics of opening the garbage collection on the most popular models, eliminate common errors and talk about the intricacies of maintaining the dust collection system.
Before you start maintenance, you need to make sure that the device is in a switched off state or is on the base for charging, this will ensure safety and allow you to safely study the structure without the risk of accidental start of the engine.
The main types of container fastening from Xiaomi
Xiaomi’s engineering solutions have evolved with the model range, so there are several fundamentally different ways to fix a dust collector today. Understanding what type of device your device is is key to successfully removing a container without brute force.
The first and most common type is the top valve lid, and in models like the Roborock S5 or Mijia 1S, the container itself is removed completely, and access to the garbage is opened through a special top lid, and it's important not to confuse the direction of opening, because the mechanism often has a hidden lock from accidental disclosure.
The second type is typical of flagship models with wet cleaning function, such as the Roborock S7 or S8. It uses a system of quick-removal modules, where the dust collector can be combined with a water tank or placed next to it, in such cases, it is often necessary to press special tongues on the sides or behind.
💡
Always visually inspect the case for arrows or "Open" icons before putting force on the details.
The third type is found in compact models and self-emptying devices, where you may need to do a specific sequence of things, like pressing two buttons at once, and ignoring this rule will result in the container not opening.
Step-by-step: classic models Roborock and Mijia
Consider the action algorithm for the most mass-produced group of devices, including the S5, S6, E4, E5 series and their modifications, and these devices have standardized the process of removing and opening the garbage collection, but require carefulness.
First, turn the robot vacuum cleaner upside down, or remove the top cover of the case if the structure allows access from above. Find a dust collector, which is a plastic block that occupies a significant portion of the internal volume, and it is usually fixed with one or two latches.
Press the lock on the end of the container and smoothly pull the module over yourself. Don't pull sharply so as not to damage the contacts of the filling sensor. After extraction, find a button or lever on the top of the container marked with the opening icon.
☑️ The algorithm for garbage extraction
When you open the garbage lid, hold the body with your second hand so that the insides don't fall out abruptly. Inside, you'll see the cleaning net and the main filter, and this is where the fine dust most often accumulates, clogging the pores of the material.
⚠️ Warning: Never open the garbage lid above carpet or upholstered furniture, as when pressure is relieved, some of the dust can fly back into the room.
Features of models with wet cleaning function
In models that support wet cleaning, such as the Roborock S7 MaxV or Xiaomi Vacuum-Mop 2 Pro, the design of the garbage collection is complicated by the presence of an electronic pump or valves.
Often, in such devices, the dust collector and the water tank are a single unit or are arranged in tandem. To open the garbage collector, you may need to first disconnect the water tank.
Some versions of Viomi use a system where the garbage collector is hidden under a decorative panel, you have to lift the panel, take up special notches, and then access the container. The mechanism for opening the lid here is often in the form of a sliding latch.
Particular attention should be paid to electronic components that can be located on the walls of the container in models with self-emptying or filling control.
It is recommended to regularly check the condition of sealing gums at the junction of the container and the main suction channel, and their damage will lead to loss of traction and reduced cleaning efficiency, even if the filters are clean.
Caring for filters and filtration systems
Proper operation of the waste collection is impossible without understanding the principles of the filtration system. Xiaomi robots usually use a multi-stage system that includes a cyclone compartment, a fine filter and a multi-stage system. HEPA-filter.
Filters must be removed carefully by taking the plastic frame, not the filter material itself. tapping the filter on the edge of the sink allows you to remove the bulk of the dust.
After washing, the filters must dry for at least 24 hours in a well-ventilated room, and using a wet filter will cause moisture to enter the engine, which is a guaranteed way to disable the device.
| Type of filter | Can I wash? | Replacement frequency | Features |
|---|---|---|---|
| Preliminary (grid) | Yes. | As pollution progresses | Detains large dust |
| HEPA (white corrugated) | Just be careful. | 6-12 months | Requires full drying |
| Electronic sensor | No. | No, he doesn't. | Wash with dry cloth |
| Coal filter | No. | 3-6 months | Removes odors. |
For extension of service HEPA-You can use a compressor or a can of compressed air to purify, instead of frequent contact with water, and this preserves the structure of the fibers and the filtration efficiency.
Solving problems with a jammed container
Sometimes users are faced with a situation where the garbage collector is not opened or removed from the housing, most often caused by overflow of the container or getting large debris into the latch mechanism.
If the container is stuck, don't try to knock it out on the floor. Turn the device over and inspect the insides through the dust collection hole, and there may be a large piece of paper or a lump of wool stuck there that blocks the movement of parts.
In cases where the garbage lid itself is jammed, try pressing it slightly into the closed position before clicking, and then opening it again, which will help unlock the latch mechanism, which may have shifted due to vibration.
What to do if the plastic latch breaks?
If you have regular opening problems, it is worth checking for cracks in the container body. The plastic loses its elasticity over time, and microcracks can grow, disrupting the geometry of the part.
Cleaning sensors and internal channels
Beyond the container itself, it is critical to keep the channels through which air flows in clean. Xiaomi models often have the problem of having the garbage bag open, but no suction due to a clogged inlet.
Use a soft brush or dry toothbrush to clean the nets at the turbine entrance.Do not use sharp objects such as needles or spokes, as you can damage the fan blades or punctur the partition.
Special attention is required by the filling sensors, which are usually located at the top of the container or in the channel of the housing, and dusting these sensors leads to false overflow signals, even if the container is empty.
⚠️ Warning: Using a vacuum cleaner with a damaged or loosely closed garbage collector will cause dust to be released into the engine compartment and the electronics to fail.
Regular prevention of suction channels allows to maintain the power of suction at the factory level for many years of operation.
Replacement and disposal of consumables
The resources of the basic filter elements are not infinite. HEPA-the material degrades, and it ceases to retain fine dust and allergens.
The need for replacement can be determined by the appearance: if the filter is grayed throughout the depth, deformed or has an unpleasant odor, it must be replaced. Xiaomi’s original filters often have a color indicator that changes over time.
When disposing of old filters, it is recommended to pack them in a plastic bag so that the accumulated dust does not get back into the air, which is especially true for families with allergies.
💡
Timely replacement of filters and proper disposal of garbage ensure stable engine operation and high quality cleaning.
When buying new consumables, make sure that they are compatible with your modification of the robot, as the dimensions of containers from different generations of Roborock and Mijia can vary by millimeters, which is critical for tightness.
