Today, with the frequent occurrence of intelligent hardware, digital and electrical products can’t be shot if they don’t connect with AI. As a sweeping robot that initially used “smart” as its core feature, how can it maintain its living position nowadays?
The “robot” that comes with its original name is a collection of various types of precision components and complex algorithms. At the higher requirements of people, today’s sweeping robots are closer to “robots” on the original basis. The title of the stone sweeping robot is like this. I was fortunate enough to get the new sweeping robot of Stone Technology in the first time, and today we will take a deeper look at it by “seeing details, talking about design, and discussing functions”.
Appearance
In terms of packaging, the stone sweeping robot can be described as “thick”. There are two layers of cardboard package inside and outside. The double-layer packaging can not only ensure the safety of the product during transportation but also protect the inner packaging. In terms of details, the package has a built-in partition that is divided into a number of partitions and is individually packaged for important parts such as water tanks and charging stands.
Regarding appearance, the stone sweeping robot adopts a minimalist design style, no exaggerated style design, and no fancy texture pattern. The pure white mirror body is resembling piano painting and decorated with rose gold, making it a comfortable first impression on the visual perception, and this minimalist product design style is also the current mainstream intelligent hardware design.
In terms of size, the stone sweeping robot has a width of 350mm, a length of 353mm, a thickness of 96.5mm, and a weight of about 350g. It is light compared with similar products, and it also increases the passability in its cleaning work.
In detail, the front end of the stone sweeping robot has three physical buttons, which are used for partial cleaning, cleaning/switching, and recharging functions. In actual use, the user can perform a multi-function operation according to the long press or short press, and the basic operation can be performed without the linkage of the smartphone. At the top of the stone sweeping robot, we can see the slightly protruding laser head pressure sensor and LDS laser distance measuring sensor, which is not only the core sensing component of the stone sweeping robot. At the same time, the component is also very rare in the same level of products (the stone sweeping robot has 13 types of sensor), which will be introduced in detail in the following articles.
Unlike most similar products, the stone sweeping robot does not use the bottom or side dust box design, but puts it in the belly of the robot and removes it from the upper end by lifting the surface buckle of the body. This design not only reduces the difficulty of dust box replacement but also avoids the process of inverting or side-tiling the robot when removing the dust box, thereby greatly reducing the dust overflow during dust box cleaning.
In the protective cover, we can also see the WIFI indicator (slow flash, fast flash, and constantly light to express different network status) and the system reset button next to it, At the same time, you can also see the amount of dust stored inside through the dust box, and grasp the cleaning requirements in the first time. To remove the dust box, it can be easily taken out by the light-locking box top lock. I also carried out several rounds of tests in actual use. There was not a lot of dust spilling during the removal process, and the sealing was not bad.
The dust box design of the stone sweeping robot is also very clever. The filter itself is the buckle cover of the dust box, and it can be removed directly when cleaning the dust. At the same time, the filter screen supports direct water washing, but it must be dried before nest use.
At the same time, the stone sweeping robot is equipped with a “small bird knife” on the left side of the dust box, which can also clean the filter through its brush, and also cut the hair wrapped around the main brush, it is a really thoughtful detail. In addition, due to its special handling structure, the dust box capacity of the sweeping robot is relatively small, but it is still enough to support the accumulation of dust for several days in a house of more than 100 square meters.
On the side of the stone sweeping robot, there are many sensors that escort for its normal operation. These include the front-end recharge sensor and the right-side wall sensor, while the front half of the machine is a collision sensor, which greatly reduces the accidental collision of the stone sweeping robot during work. On the back side of the fuselage, the large area of the air includes speakers and exhaust vents. Compared with what has said before, the bottom structure of the stone sweeping robot is more complicated. In addition to the main brush, side brush, universal wheel and left and right main wheels that everyone can visually see, there are multiple sensors and reserved seats for the side tank.
Many people will doubt the design of the “unilateral brush” of the stone sweeping robot. This has been the case for me too but after a period of testing and targeted research, I found the unilateral brush can not only avoid the “two brushes stack together” situation of the bilateral brush machine but with the support of the planning algorithm, it still has the cleaning efficiency as much as the bilateral brush machine, and the details like this may only be experienced by the used person.
In detail, there are two charging contacts and four cliff sensors at the front end of the stone sweeping robot to avoid the accidental drop. At the same time, the stone sweeping robot also adopts a floating main brush design. The main brush can be floated up and down according to the ground, and the main wheel of the large diameter is matched with the ground as much as possible to increase the cleaning efficiency.
Many people are tired of the cumbersome cleaning process when using the sweeping robot, while the stone sweeping robot responds with a minimalist disassembly design. If you want to remove the main brush, you can easily remove it by pressing the main brush guard. Whether you are cleaning the dust or washing it (remember to dry it), the loading process is also very convenient. In addition, the main brush, side brush and universal wheel are designed with anti-hair to avoid the jam caused by entanglement during use. However, I suggested that you should always pay attention to the main brush and the side brush, and clean it frequently, to ensure a high cleaning efficiency of the sweeping robot.
In terms of configuration, the stone sweeping robot has a built-in NIDEC brushless fan. According to the data, its peak suction can reach 2000Pa, with a streamlined air duct system based on aerodynamic design, and a bellows design to form a high quiet zone, which is greatly increased. The suction also effectively reduces the noise generation.
To say that this sweeping robot cannot be separated is its own “small home” charging seat. This charging seat of the stone sweeping robot is designed relatively more careful. It not only designs a special pallet at the bottom but also sets a number of non-slip contacts at the bottom of the pallet, which is matched with the fastening of the charging socket, greatly avoiding the accidental collision of the sweeping robot. In addition, the new infrared charging stand can send infrared signals to the outside, the host can sense its position at a long distance and ready for recharge, with its overcurrent, overvoltage, short circuit protection and low voltage DC 20V harmless power supply. This charger is safe and reliable.
As a multi-purpose sweeping robot, the stone sweeping robot also supports the wet mop function. After filling the water tank, it can be installed with the back side of the bottom of the fuselage. With the support of the plant bionic wet mop system, the water in the full tank can be evenly and slowly arranged, and it will not leak under non-moving conditions. In the full water state, it can support about 40 minutes of mopping work in a single time, and it can be cleaned, vacuumed and wetted at the same time without disassembling components, which greatly increases the cleaning efficiency. However, don’t forget to clean the wet mop at the bottom of the tank regularly.
Using Experience
It is said that the core technology of this sweeping robot is the intelligent algorithm and path planning, and this is also the strength of the stone sweeping robot. Thanks to the 5WD rotation of the top LDS laser ranging sensor, the stone sweeping robot accurately draws a scene image similar to the “CAD” pattern and plans working route easily according to the obstacle position. Compared with traditional analog products that use infrared, collision, and visual planning, laser ranging is more sophisticated, and it can also greatly reduce planning errors.
Say this “good horse with a good saddle”, excellent hardware will be better with the excellent intelligent platform. Thanks to the strong support of Xiaomi Mijia’s ecological chain, the stone sweeping robot can be directly authorized to access through the Mijia in the mobile phone, and its operation process is extremely simple. In the system, I can use the mobile phone to open the stone sweeping robot with, recharge, designated area cleaning, and real-time control. It can also view the historical working status of the robot through its built-in recording function.
Talking about being practical, I prefer the maintenance function of maintenance, timing cleaning, and cleaning mode. Set up cleaning every day before going home from work, and enjoy the clean floor when entering the house. In addition, the stone sweeping robot also supports the “personal voice package” function. Users can choose their favorite sound effects in multiple preset voices such as robots and animations according to their own preferences, so that “Optimus Prime” can clean the room for us. The experience is really interesting.
About actual experience, the stone sweeping robot appears to be similar to other products, but it is relatively “smarter”. When cleaning the edges and corners, the collision probability is significantly less. The excellent SLAM planning algorithm is equipped with a Z-line cleaning path, which also makes it less likely to have a “blind point” in cleaning efficiency. In addition, the stone sweeping robot can easily cross the ordinary foot line barrier (2cm arc slot line), while automatically recognizing the carpet and opening a large suction to clean it. Although the 96.5mm body is sufficient for deep cleaning of the edges and corners, the cliff sensor can also ensure the safety of the robot during the cleaning process. (I have placed it on the round table for 30 minutes of continuous testing, no drop occurs)
In terms of battery life, the stone sweeping robot has a built-in 5200mAh large-capacity battery. However, due to practical conditions, I have not tested the working time limit at full power, which is a little pity.
Unlike most sweeping robots, which use the “follow the wall” strategy, thanks to the LDS laser intelligent rapid exploration technology, the stone sweeping robot can go straight to the charging stand for a quick recharge without having to take more roads. At the same time, the stone sweeping robot supports the automatic recharge and power-off continuous sweep function, and even if the work is interrupted, the last unfinished cleaning work can be continued after the energy storage.
