OFweek smart home network news: sweeping robot has entered every household in the past few years, especially in today's fast-paced life and work, and most people live alone, or two or three people, but these people have a The common denominator is that there is not much time to clean up the places where they live. Usually, they are free to clean up on weekends.
So it is necessary to have a sweeping robot, and the Cobos DD35, as a product of the backbone, has many remarkable features.
Exterior
Cobos DD35 (hereinafter referred to as DD35) has a very large package and is very thick. There is also a handle above the box. It is convenient for handling, with the logo of Coworth's logo and the appearance of DD35. There is a two-dimensional code of Alibaba Cloud App. This product is also in cooperation with it. After downloading the App, multiple controls can be implemented.
(For product details)
After opening the package, the inside was almost full, and the huge DD35 took up 80% of the space. There were also various accessories and gifts. Accessories include a charging base, two brush heads, manual, remote control, and two batteries; gifts include rags, two brush heads, and HEPA filters.

Then look at the protagonist DD35, round body shape, using a gray-based color, looks a little geek Feel, with a lot of lines to embellish, feels like Tony Stark (Iron Man) family will The products used by the author are very much liked by the author, but for female users, their love may not be as high as that of men.
(The upper white is the bumper strip, which needs to be torn off before use)
There is only one Auto button on the front of the DD35. Even if you don't download the app, you can clean it by pressing this button. The children up to the age of 6 or 7 can access the 60 to 70-year-olds. use. Next to the button, there is a WiFi logo and four signal lights. The WiFi logo light will light up when WiFi is connected.
Right below is Coworth's English Logo, flip up the front cover, there is a power key, and can also be out of the trash box for cleaning.
(Transparent blue plastic container is used to hold water, and can be dragged after installing a rag holder)
After turning the machine over, you can see two big wheels, a small roller, a roller brush, and two cyclone brushes installed. Unconventional whole, Virgo people will love this layout.
Overall, the appearance is in line with the Geek family's aesthetic, and it has a strong sense of science and technology, but it is a pity that the fuselage is almost entirely made of plastic material, feel more general, but honestly, the opportunity to touch it is also very less.
App
Scan the QR code on the box to download Alibaba Cloud App. After you open the app, you can connect with the DD35. The process is very simple. When you connect, you can enter the WiFi password for the robot at home. In one go, there is no difficulty in getting started.
(Remote control interface, and when the DD35 malfunctions, not only the machine will give a warning sound, App will also display the fault information)
The App's control interface is also very concise, and the required functions are all clear. There are three types of sweeping modes, automatic, edge and fixed, and the most frequently used is the automatic mode. After starting this mode, the DD35 will start cleaning. The app can see the cleaning time and area. In addition, it also draws sweep maps, but it has no reference significance.
Edge and fixed point modes are used in special environments. For example, a place is very dirty and needs to be cleaned. In addition to this, the most practical one is timing cleaning. In the App, you can reserve a time period. When this time comes, the DD35 will automatically begin cleaning. When you go to work, you can schedule it to be cleaned. It will not affect people.
(When using a mobile phone for remote control)
If you are unsatisfied with the DD35's sweeping route, you can also grab the control right, because you can control it remotely in the App, you can control the DD35 before and after and walk counterclockwise, when you press the "forward", DD35 will walk Clean, fun and practical.
Features
Judging from the official publicity, the DD35's functions feel more and more practical. So what exactly is the real situation? To test the truth, we still need to go through practice. Then the author will also test one item in this section to see if its functions are true, practical, or gimmick.
Since it is a sweeping robot, first of all, we look at the performance of the DD35 from the ability to sweep the ground. I put some of the common rubbish in every corner of the home, and then turn on the automatic mode for cleaning.
("bow" shaped sweeping route)
(Small obstacles will be removed and cleaned during slow speed)
During the cleaning process, the walking route of the DD35 is a “bow†shape. Officially called the Smart Move, the DD35 is able to clean up in the face of daily garbage, and it has a slow-moving cleaning function.
Most sweeping robots are equipped with ultrasonic sensors, which are avoided when they encounter obstacles. Even if they touch the curtains, the DD35's low-speed sweep function will reduce the speed when it encounters obstacles. To clean it up, it will cross between curtains and small obstacles. The advantage is that it can be cleaned up in place. The only minor drawback is that it will hit some small items in the house.
(Basically, it can still be cleaned)
In addition, it can automatically record which areas have been cleaned and avoid repeated swipes. After cleaning all areas, the DD35 will send out a “search for new area†prompt, and if it is not found, it will automatically return to the charging base to restore strength.
In addition, DD35 also has "Blue Whale Cleaning System 2.0" equipped with a blue whale micro-controlled water tank that can hold 300ml of water, used in combination with a constant-pressure floating rag, and can adjust the water seepage strength of the tank in the app. Low, medium and high levels can be adjusted. During the process of mopping, only after the DD35 recognizes that the rag holder has been installed, the App will display the adjustment of the water quantity and the water tank will begin to seep. If the rag holder is removed, the seepage will stop and be very intelligent to prevent mistakes. operating. In the process of mopping the ground, the sweeping work is also carried out simultaneously.
In addition, passability is also a big challenge for sweeping robots. 95% of the measured homes can be perfectly cleaned. The only place that cannot pass is at the toilet's threshold. The high drop makes the DD35's wheel unattended and unable to walk. A warning sound will be issued and the user will be alerted in the app.
(After pressing “Recharge†in the app or it identifies cleaning, it will automatically find the charging cradle and return)
Of course, the smart hardware is the smart side. The DD35 can recognize the sweeping environment. When it recognizes the bedroom and other rooms, it is cleaned and there is no area to go. At this time, it does not operate blindly. Instead, it finds the charging base and returns. Charging, this is very humane.
After using it for a whole week, when the author came back to sum up the advantages and disadvantages of the DD35, he could not help but sigh. During this time it really saved a lot of time, no longer need to take the broom and mop to clean at night. Home hygiene, starting DD35 is enough. However, there is also a small complaint about noise during operation. Although the official stated that the noise of the DD35 has been controlled at 55 dB, starting from subjective feelings, it inevitably affected me at certain times. The daytime is fine, but it really feels noisy at night.
For example, once I set up the DD35 to clean automatically at 6:30 in the morning, the result was not the alarm clock that called me that morning, but the D335's noise, but also a bit weeping. In addition, in terms of battery life, after 19 minutes of cleaning and mopping (with a small fraction of the standby time), the DD35's electricity fell from 100% to 71%.
In general, DD35 can still face daily small garbage well, as long as your home is not too messy, basically use it every day, can maintain a long-term clean at home, of course, you have to keep clean DD35 Row.
to sum up
As a company established nearly 20 years ago, Cobos has laid a very solid foundation. As the DD35 is a mid- to high-end product, the current price of 1,999 yuan also plays an important role in the volume, and the overall advantages are better. Overdue, the author is also very happy to use.
For example, if you ask a clean aunt, you need 35 yuan a day, and you have spent more than 10,000 yuan a year. In addition, a sweeping robot can use it for a whole year. It takes 5.4 yuan to clean the house, but of course, it is not comparable to cleaning the aunt, but it also guarantees the basic health conditions at home.
The DD35 can't fly, but it can save me a considerable amount of time, and as a smart hardware product, it is worthy of a name. If you can make the battery a little bigger and the noise is reduced a bit, it would be better.
High resolution
In order to realize a large-area high-resolution Liquid Crystal Display, it is usually necessary to use low-impedance metal materials, high-performance switching elements, and high-precision processing techniques. Aluminum is the most researched and used material for making TFT buses with low-impedance metals. By solving the problems of easy formation of hillocks, chemical corrosion and oxidation of aluminum, alloy methods (such as Al-Cu, Al-Si, Al-Nd and Al-Ti, etc.) and interlayer methods (such as Mo/Al/Mo) have been reported successively. , Cr/Al/Cr and Ti/Al/Ti, etc.), the alloy method is relatively simple in process, but the material has a higher resistivity. In May 1998, IBM developed a 16.3-inch ultra-high resolution (200ppi) a-Si TFT Display using Al-Nd alloy as the gate electrode, and mass production has been achieved. In April 1999, Toshiba introduced the 20.8-inch 16-SVGA (3, 200 × 2, 400) a-Si TFT-LCD, which can be said to represent the highest level of a-Si TFT-LCD in terms of high resolution and high capacity. .
According to Display Search in the third quarter of 2011, the global flat panel display research report "QuarterlyWorldw ide Flat Pane l Dis play Fore cas t Re port" pointed out that the average pixels per inch (ppi) in large-size LCD panels (>9.1 inches) ) Will grow from 88ppi in 2010 to 98ppi in 2015. The ppi of small and medium-sized LCD panels (<9.0 inches) will grow from 180ppi to 300ppi in the same period. With the rise of smart phones, mobile phones will be the most obvious application product for ppi's growth.
Another important way to realize high-resolution liquid crystal display is to develop LT p-Si TFT technology. The resolution of published p-SiTFT-LCD products is generally around 200ppi. Compared with a-Si TFT-LCD, LT p-Si TFT-LCD has a smaller volume of thin film transistors and storage capacitors. Therefore, it has a larger penetration area per inch, resulting in a brighter display. , And save more power. When the market demands higher ppi, low-temperature polysilicon (LTPS) technology becomes the best choice for manufacturing high-resolution thin-film transistor liquid crystal displays.
Contrast
The control ICs, filters and oriented films used in LCD manufacturing are related to the contrast of the panel. For general users, a contrast ratio of 350:1 is sufficient, but such contrast in the professional field does not satisfy users. Demand. Compared with CRT monitors easily reaching 500:1 or even higher contrast, only high-end LCD monitors can achieve this level. The first-tier LCD monitors on the market, such as Samsung, Asus, LG, etc., can reach a contrast ratio of 1000:1. However, because the contrast is difficult to accurately measure with instruments, you have to go and see it yourself when you pick it.
Tip: Contrast is very important. It can be said that the selection of LCD is a more important indicator than bright spots. When you understand that your customers buy LCDs for entertainment and watching DVDs, you can emphasize that contrast is more important than no dead pixels. We When watching streaming media, the brightness of the source is generally not large, but to see the contrast of light and dark in the scene of the character, the texture change from gray to black hair must be shown by the level of contrast. The 256-level grayscale in the test software In the test, more small gray grids can be seen clearly when looking up, which means that the contrast is better!a
