The heavy work and life are testing our patience with the tedious housework all the time, especially the tired and dangerous housework of cleaning the windows. Nowadays, the glass windows, especially the glass windows of the closed balcony, are both large and high. Even if you clean the room, you need ladders and chairs, not to mention the external windows that are more than ten or twenty floors high, It's not many years ago that "Flying Man in the Air" really can't do this job, so I'm very honored to be here Love to play computer games The trial platform got this experience opportunity - W850, which once again defended the author's glorious title of "lazy patient".

Appearance and details                                         

Covos is a leading enterprise in the research, development, manufacturing and sales of domestic home service robots. It has broken through the tradition and developed the first automatic window cleaning robot in China, the Covos Window Treasure series. It has solved the limitations of manual window cleaning, effectively avoided the dangers caused by high altitude window cleaning, and it does not need manual assistance to clean, It is easy to attach it to the glass with one button and automatically plan the route to clean the window.

Kevos Window Treasure W850 is not stingy in terms of accessories. In addition to the main packing box, it also includes a spare parts box. The family portrait includes the host * 1 (with its own 2.8m power cable), adapter * 1, 1.5m extension power cable * 1, remote control (with two No. 7 batteries inside) * 1, safety buckle * 1, elastic seat belt * 1, cleaning cloth * 4, cleaning cloth * 1, special cleaning solution * 1, instructions * 1, and quality assurance card * 1.

In order to control its own weight, the W850 is made of plastic as a whole. The panel and handle are respectively made of bright baking paint and imitation metal wire drawing process. Although there is no bright spot in the appearance, it is not annoying. It is this mediocrity and non obtrusiveness that makes it easier to integrate into the home environment.

The side of the fuselage is designed with upper and lower double anti-collision panels, and the touch switch is used to sense obstacles such as window frames. However, in actual use, the curtain rod higher than the anti-collision panel will be encountered, so manual remote control is required to avoid.

The guide wheels at the four corners can assist the steering system to carry out accurate positioning and avoid missed route deviation.

The handle adopts a closed design, which can prevent the power cord from winding during operation. At the same time, the control switch is designed on the handle to facilitate single hand operation.

There are anti falling sensors, cleaning cloth magic glue, dust strips, power switches, driving wheels, driving tracks, vacuum centrifugal fans, indicator lights, and floating pressure sensors on the back of the product.

The walking system adopts the combination of soft driving track and powerful driving wheel, which can effectively avoid the phenomenon of sliding on the smooth glass surface.

The bottom is equipped with a high-speed vacuum coreless brushless fan, which can produce a 2.8 kPa super suction force to make the window guard safely cling to the glass window, and can also withstand a vertical load of 58N and a horizontal pull force of 73N. After conversion, it has a vertical load of nearly 6kg. It can be used together with safety buckles to prevent accidental falls to the greatest extent.

The floating pressure sensor can increase the fitting degree to meet the cleaning of stubborn stains on different planes.

The flexible silica gel dust scraping strip, together with the cleaning cloth, can complete the key cleaning of wiping scraping wiping in one cleaning.

Preparation before use

Before use, it is necessary to confirm the size of the cleaning area and the position of the power supply, and use the extension power cord as appropriate. At the same time, the locking setting of the power cord interface also provides protection against accidental falls.

Install the cleaning rag at the corresponding velcro position, and ensure that the alignment is flat and fit, so as not to affect the normal operation of the anti drop identifier, and spray the special cleaning liquid properly. Here, pay attention to control the spraying amount of cleaning liquid, to avoid leaving water stains on the glass when spraying too much. Finally, use the cleaning cloth to wipe the drive track and fan air inlet and other positions, Prevent liquid from entering the machine and causing damage.

After turning on the power switch, the fan starts to work, and then it can be placed on the working glass surface.

The above figure is just for demonstration. If it is to clean the exterior window of the high-rise building, it is necessary to fix the safety buckle at a suitable position inside the glass.

Cleaning route planning

The W850 has two route planning modes, different from the W830, which needs manual adjustment. The W850 can automatically determine the route mode according to the actual situation of the window, but it can also be manually adjusted.

The two route planning modes are N-shaped and Z-shaped, which means vertical cleaning or horizontal cleaning. They are applicable to glass in vertical and horizontal lengths.

Actual measurement of cleaning effect

In order to make it easier to see the cleaning effect, the author used a colored pen to doodle, and made corresponding marks on the edges and corners that are easy to miss.

The whole cleaning process was relatively smooth, and the cleaning process was divided into three stages: area identification, specified route cleaning, and returning to the starting point. However, there was a trapped situation at the beginning, and it was normal after restart. In particular, the design of returning to the starting point after completion is very convenient, which can be easily placed and withdrawn when the external window is cleaned. It will stop automatically after cleaning. If you can set the number of automatic cleaning times, I believe it will be more convenient to face heavily polluted glass.

From the above figure, we can see the overall contrast effect after cleaning. The left side is the uncleaned area, and the right side is the cleaned area. The cleaning effect is good in the face of long-term accumulated water stains and stubborn dust.

The above figure shows the effect of cleaning the inside single-sided glass. It can be seen that since the cleaning rags are distributed around the edges of the host, there is almost no omission in cleaning the extended edges, and the marks made by the colored pens have been cleaned.

However, because the four corners of the W850 are designed with guide wheels, which are not covered here, it has become a dead corner for cleaning. There are obvious markers left here.

Simulated power-off demonstration

Kevos Window Treasure W850 has a built-in lithium battery, which can ensure that the fan continues to work within 15 minutes of accidental power failure to prevent falling. This function, together with the safety buckle, provides dual safety protection against falling.

Clean with cleaning cloth

Kevos Window Treasure W850 cleaning rag is made of high fiber material, which has outstanding moisture retention and cleaning ability and is very easy to clean. In the test phase, the color pen graffiti used by the author dyed the rag with full body makeup. At first, I was worried that the rag would become a big flowery face, but there was basically no color residue after cleaning.

Applicable scenarios

Cowos Window Treasure W850 is not only limited to cleaning glass, but also can clean different flat surfaces, such as floors, boards, tiles, frosted glass, etc.

However, this kind of glass with curved surface cannot be cleaned. There is no problem through testing the fan adsorption system. The key is that the crawler type walking system cannot fully fit on the curved surface, resulting in difficult walking. In future product iterations, floating wheels can be considered to increase the walking ability.

summary

Advantages: floating duster cloth, high fitting degree, with the key cleaning method of wiping scraping wiping, outstanding cleaning ability; It has multiple safety protections such as power failure protection, fall prevention induction, anti-collision plate, safety buckle, etc; One touch non-interference free cleaning mode, which automatically returns to the starting point after completion, avoiding high altitude hazards and reducing labor force; High fiber rag for easy cleaning;

Disadvantages: The official guidance price of 2380 yuan is slightly higher; It is impossible to clean small areas; Four corners have cleaning blind areas; The anti-collision board cannot sense when it encounters a high curtain rod; Encountered a corner trapped; Automatic multiple cleaning cannot be set;

On the whole, the W850 of Kevos Window Treasure has an efficient and intelligent cleaning ability in the actual test. It is a window cleaning artifact that can avoid the risk of work at heights and reduce the labor force. You can easily enjoy the brightness in front of the window and feel the convenience brought by technology to our life.
