Mijia sweeping robot 1C experience: “visible” clean.

The original intention of smart home is to bring more happiness to people’s lives. So the dishes were handed over to the dishwasher, and the floor was handed over to the intelligent floor sweeping robot. The emergence of smart home can be said to have greatly changed the lifestyle of contemporary people.

The sweeping robot is one of the most common smart homes, and it is also the most popular smart product. The price difference between them is very big, but it sounds similar in function. Smart sweeping robots often follow price priorities. Price determines the experience. The recent fire Mijia Sweeping robot 1C is a bit like an experience-first product. Consumer feedback is pretty good. After using it for a while, we also concluded an experience report.

Due to the length of the article. So here is our test conclusion: Mijia 1C is a 70-point product. Most of the functions of a sweeping robot can basically do it. And can pass the standard. But each performance is not outstanding. Mijia 1C is relatively slow to clean. At maximum suction, the noise is louder. According to official information, a 120m² room can be cleaned at one time when fully charged. Depending on the scene structure, the actual time will be reduced to some extent.

Here is the configuration table:

In general. Mijia Sweeping robot 1C is suitable for small apartment users. Its positioning is more like auxiliary equipment. If you are curious about this conclusion, let’s take a look at our detailed test content.

Design

The appearance design style of Mijia 1C still retains Mijia’s consistent minimalist style. The plastic body is mainly white. The included accessories are also very simple. Side brush, charging pile, power cord, mop & water tank, tools for cleaning the main brush, and instructions.

Due to different product positioning. Mijia 1C uses visual navigation. Therefore, the LDS laser navigation module that was originally convex on the front was replaced with a non-convex camera. This advantage is that on the one hand, the cost is controlled, and on the other hand, the body is more complete and beautiful. Mijia 1C implements positioning and navigation through a camera. During the actual cleaning process. Calculate the actual walking displacement by calculating the displacement difference of the ceiling. Then draw the corresponding cleaning map.

Simply say. The visual navigation used by Mijia 1C is not as accurate as laser navigation. Therefore, in the actual cleaning process, a map is drawn while colliding. This leads to low cleaning efficiency in an environment with complex scene structures. At the same time, the cleaning speed of Mijia 1C is not fast. So if someone at home is active, it is not suitable for work.

There are two physical buttons on the front of the camera. They are the power button and the recharge button. Press and hold the power button for 3 seconds to turn on / off; after turning on, short press to start the cleaning mode; flashing orange light is a fault state. In the power-on state, short press the recharge button to start the recharge, and long press for 2 seconds to start the partial cleaning; flashing orange light is in the low battery recharging state, showing the orange breathing light effect is in the low battery charging state, and the white light is always the charging completion. It should be noted that, during cleaning, recharging and partial cleaning, pressing any button will suspend the current work.

The front of the Mijia 1C is partially openable. Open the outer protective cover, you can see the inner dust box, reset button and WiFi indicator.

It is very convenient to remove and place the dust box, and the operation can be completed with one hand. However, the opening and closing operation of the dust box body is slightly laborious. If there is a lot of dust in the dust box after cleaning, you need to pay more attention when you open the cover to clean up the garbage. The dust box has a capacity of 600ml, which is relatively large. Take an example of a room of about 35m². After a complete cleaning, it will take up about half of the dust box.

7 sets of infrared deceleration sensors are integrated inside the front buffer belt. Can detect obstructing objects in the range of 20CM. Then identify and slow down to reduce collision damage. Behind the fuselage is a row of circular openings. There are two uses here: one is the exhaust vent, and the other is the speaker.

At the top of the bottom of the fuselage is a caster. The square metal blocks on both sides are the charging electrodes. Further down is a single-bristle brush on the left and a motion tracker on the right. In addition, there are four cliff sensors at the outermost periphery of the bottom of the fuselage, which are used to identify the high drop and avoid falling at high altitude. At the center line are two large main wheels for driving and cushioning. Inside the main wheel is the most central cleaning component, the main brush, which is designed to be removable.

The groove in the lower part is used to install the intelligent electric water tank. Mijia 1C can mop. Its water tank capacity is 200ml, which is not large. However, its built-in electric-controlled water pump can guarantee full automatic and even water discharge. The surface of the water tank is covered with a mop, which is designed with a Velcro. Easy to clean and reusable. Mijia 1C does not come with extra mops, so you can only use it repeatedly.

The body size of the charging pile is much smaller than the previous generation. The benefit is that it saves more space. The disadvantage is that there is no wire storage capacity. When the robot is working, the extra wires are easily dragged away by the robot. Therefore, if the charging pile has a wire storage function, the experience will be much better.

Link Mijia

The connection method of Mijia 1C is very simple. After entering Mijia App, click the “+” button in the upper right corner of the screen to find the product model you need to connect. When connecting Mijia 1C, you need to press the power button and the recharge button on the front of the fuselage at the same time for WiFi connection. It should be noted that Mijia 1C does not currently support 5G WiFi.

After the connection is successful, you can control related operations through the App. Such as recharging, turning on / off cleaning, adjusting the cleaning mode (quiet / standard / mid-range / powerful), regular cleaning, and changing robot voice. During the cleaning process, the app displays the area that has been cleaned and counts the area that has been cleaned, as well as the cleaning time and remaining power.

As you can see, the operation page of Mijia 1C is very simple and intuitive. It does not support partitioning. Strictly speaking, it does not support virtual partitions, which means that you cannot draw a virtual wall in the cleaning map. Mijia 1C currently only supports two modes: global cleaning and scheduled cleaning. Functions such as designated areas and memory maps are not yet available.

Why say “now”? Because Xiaomi officially stated that it would improve the functionality of Mijia 1C through firmware upgrade. No firmware upgrade notification has been received.

However, one interesting feature of Mijia 1C is smart scenes. This function can link Mijia 1C with other Mijia products, such as Mijia smart door locks. You can associate the two products in the smart scene page. After the association, you can detect that the person has left the house through the smart door lock, and then cooperate with Mijia 1C to start the cleaning work.

Mock test

Path planning is one of the most core technologies of sweeping robots. After all, the quality of path planning directly affects the efficiency of the cleaning robot. As mentioned earlier, Mijia 1C uses camera-based vSLAm technology. The implementation of this technology is a SLAM system that relies on images as the main environment-aware information source. Because it is more capable of collecting and identifying data, vSLAM is known as the future development direction of sweeping robots.

Mijia 1C’s camera has a wide viewing angle of 166 degrees, 30,000 visual feature points are collected per second, and path calculations are performed 50 times per second. Looks very good from the parameters, so how does it actually perform?

My personal experience is that the fuselage advantages of Mijia 1C based on the visual navigation structure give it an innate advantage in passability. The thickness of the whole machine is 8.2cm. It is very easy to clean the bottom of the sofa and pass the furniture with low height such as under the table and under the bed. But the cleaning process is not easy. Build maps while bumping, and cleaning is too slow. The entire cleaning process takes a lot of time.

Specific tests. We simulated several daily cleaning scenarios, and then use gifs to show you.

Wood chip test.

Dust test.

Hair test.

Liquid test.

The above tests are performed in standard mode. Among them, wood chips, paper chips, and hair were the most complete of the three tests, and they were relatively clean. The dust test performed poorly. Suction is insufficient in the standard state, and there will be a small amount of residue after one cleaning. Therefore, it is recommended to turn on mid-range or strong force when cleaning small dusty objects to avoid multiple cleaning.

Also need to pay attention. When testing for cleansing hair, although cleaned very clean. However, since the main brush is a single-bristle brush, after cleaning, the hair is basically wrapped around the main brush. And cleaning up is a bit laborious.

Liquid testing is also performed under standard conditions. However, we added water to the water tank and tested it with a mop. The test liquid is milk. After cleaning once, the surface liquid is completely cleaned. However, there will be a noticeable touch when touched by hand; after two cleansing, the touch will be reduced; after three cleansing, it will be completely removed.

Obstacle test.

Climbing test.

Anti-drop test.

In the obstacle test, the cable must be the most troublesome thing. Many homes today have a lot of electrical appliances, so cables are also a lot. This can cause a lot of problems for the cleaning robot, such as the cables wrapped around the wheels. After actual measurement, Mijia 1C can easily jump over when encountering a single cable. However, it is more troublesome when multiple cables are stacked. Either it hits the U-turn, or it tries to leap over. The result is that it is entangled with cables and cannot move.

The drop test performed very well. Be able to make accurate judgments efficiently and quickly. If you find a floating situation ahead, you will stop immediately, and then turn to continue work.

During the ramp test. We used sliding rails instead of ramps for testing. In actual tests, Mijia 1C can easily leap even when facing a slope of about 1.5cm. However, in the case of water in the water tank, there is a great chance that some water stains will be shaken. These water stains may come from mops or suction inlets.

Clean the dust box

After cleaning the room, it’s time to clean the sweeper body. This work can only be done by ourselves. The Mijia 1C dust box is located above the fuselage. It can be easily removed by opening the protective cover above the fuselage.

The lid of the dust box is relatively tight, and you need to use some force when you open the lid. In addition, if there is a lot of garbage in the dust box, care must be taken when opening the lid to avoid excessive movement of the garbage to cause it to fall. Mijia 1C dust box is simple in construction and easy to clean. Let me remind you that when cleaning the dust box, take out the filter first and clean it separately. After cleaning, wait until it is completely dry before putting it into the dust box for use.

Conclusion

After using Mijia 1C for a while, my feeling is: if there are not too many complicated requirements and no messy scene settings, it only needs to clean the ground where we see. Mijia 1C is fully capable.

But if your scene is more complicated, you need to think about it first. Compared with the flagship Mijia 1C, it lacks many functions. This means that it can perform limited operations. Therefore, you should summarize your needs before considering this product.
