The secret of keeping you safe from the troubles of sweeping the earth is actually here!

[PConline evaluation] We have consumed most of our energy every day to cope with the busy work. If we return home, we must continue to deal with such trivial chores. I believe that many people will complain about it! Quietly tell you that now a good day is coming. A sweeping robot that can save you from sweeping is born. It is the protagonist of our evaluation today – the Cobos DR95 Sweeper. Below, we come together to enter the evaluation section!

In December 2015, Cobos officially launched the intelligent sweeping robot DR95 with a global planning system. This sweeping robot uses the newly developed Smart Navi technology from Cobos and implements the SLAM algorithm through the LDS laser radar ranging system. The new mode of “building maps for whole house cruises” and “arching plan sweeping”. Leading a new wave of global planning, "build map first, clean afterwards". Its price is 4999 yuan.

Appearance and details

Cobos DR95 product specification is 354 × 354 × 98mm, product net weight is 3.4kg, the material is very full, with streamer gold as the main color, it looks noble and generous.

There is only one opening key on the streamer gold panel. After one key is turned on, the Cobos DR95 sweeping robot automatically enters the “exploration and mapping” mode. After the family map is built, the sweeping mode is officially started. The DR95 has a memory function for the created map. The next time it is turned on, it enters the sweep mode directly.

The eye of planning - LDS radar scanner, a scan coverage of up to 50.24 square meters, rapid cognitive home environment. LDS scans up to 300 times per minute and any home changes can be perceived and reacted in a timely manner. It is worth mentioning that there is not only a soft-touch buffer on the outside of the fuselage, even the periphery of the LDS radar scanner, but also a touch-type buffer. The design is quite user-friendly.

Open the body cap and at the top you will see a main switch of the power supply. Next to the brush, there is a cable jack that can be upgraded by connecting the robot.

The dust box capacity is 523ml, which is nearly 2 times that of the ordinary sweeping machine (normal sweeping robot is about 300ml), 3-layer precision filter, HEPA layer filter PM2.5 and other dust, and the discharged air is cleaner than the respiration air.

The Covos DR95 consists of 2 side brushes and 1 roller brush on the back. The front of the roller brush is equipped with a squeegee. The whole structure is simple and beautiful.

The bottom universal wheel has a pair of charging pole pieces and two pairs of sensing eyes on the left and right sides respectively.

Suspension drive wheels for climbing.

The Cobos DR95's roller brush is Covos's patented V-type floating roller brush, which gathers dust, does not leak ash, and sweeps more thoroughly.

Having a rotating long-edged brush at the bottom will completely remove dust from the edges of the walls and corners.

Summary: As a heavyweight product launched at the end of 2015, the Cobos DR95 will be fully marketed in 2016, allowing more consumers to experience higher-tech smart sweeping robots. The Covos DR95 not only uses ample material, but also has a noble appearance with its streamer gold appearance. With the fine workmanship, it is enough for people to put it down.

Cleaning effect test

Cobos DR95 has a noble appearance and fine details of the construction, then its cleaning ability is as good as the appearance details? Let's do a test right away.

Test item 1: sweeping oats

Test site: The range of 2m by 2m of wood

Before the test, 30 g of oats were weighed for cleaning. Since the oats were slightly smaller and lighter in size, similar to the common ground dirt on the home, they were used for cleaning. Once weighed, sprinkle the oats evenly in the test area. (Accelerated playback of video to save time for users to watch)

Test results: About 3 minutes and 25 seconds after the cleaning was completed, the cleaned oats were weighed at 30 g, which was equal to that before the test. The sweep rate is as high as 100%, so the Coworth DR95 passed it perfectly in this test.

Test item two: sweep mung beans

Test site: The range of 2m by 2m of wood

Mungbean is very small and extremely easy to roll. When you clean it with a broomstick, it always rolls around, which is troublesome. Therefore, mung bean cleaning can be said to be a small test for sweeping robots. Before the test, 30g of mung beans were weighed as the cleaning object, and were evenly sprinkled in the cleaning test area. After the cleaning was completed, the amount of mung beans cleaned was compared with that before the test, and the results were obtained. (The video is processed by accelerated playback in a minute or so.)

Test result: After sweeping for a period of time of 7 minutes and 36 seconds, all mung beans in the dust box were collected and reweighed to 30 g. Therefore, in this test, the Covos DR95 was passed once again with a 100% sweep rate.

Sweep coverage test

The home environment is generally relatively large and complex. Many people will worry about the intelligence of the sweeping robot, and fear that it can not sweep cleanly. This involves the sweeping coverage rate of sweeping robots. Therefore, the author cleans up a place in the evaluation room to simulate everyday homes. Environment, and set up 6 places marked oats to see if the Cobos DR95 sweeping robot can be fully cleaned. (The video is all processed for about one minute after accelerated playback)

Test results: In this test, Cobos DR95 once again proved its strong strength. In the shortest time (6 minutes and 23 seconds), the sweeping range covers every place, and it is cleaned almost once. After the cleaning is completed, it automatically returns to the starting position, which is very intelligent.

Summary: After three rounds of sweeping tests, whether it is cleaning mung beans, oats, or indoor home combat, the results presented by the Cobos DR95 are always very satisfactory. The cleaning rate is almost 100%. Of course, the experimental conditions may be limited, but such results can also prove that it does not have too much of a problem with daily cleaning.

Human functional test

Anti-drop ability test

Anti-drop function is one of the necessary skills for each sweeping robot. Because many families have such an environment as a staircase, a sweeping robot without anti-dropping function can easily fall, and it may cause damages and other degrees of failures, resulting in failure to continue the normal cleaning work.

Escape ability test

In a home environment, due to the presence of furniture or appliances, there are always some slightly more complicated environments, which may trap the sweeping robot so that it can't finish cleaning tasks or even stop work. Escape ability can be said to be a big test for sweeping robots, but it is also one of the metrics that determine whether a sweeper is a good product. The author in the evaluation room, simply put a path, trying to trap Cobos DR95, to see if I have not succeeded!

Anti-winding ability test

In addition to the complex environment, there are still some things in the house that the sweeping robots do not like. One of them is a variety of wires, but it is also impossible to avoid. In order for sweeping robots not to be entangled by wires, sweeping robots need to have good gradeability and their side brushes cannot be rolled up. Then follow the author to see, in the face of wires, Cobos DR95 is still not so unobstructed.

Anti-collision function test

Covos DR95 allows the body to hardly collide through the action of the sensor, and at the same time, because the rotating side brush is long enough, even if it is not against the wall, it can clean the sweeping corners.

Automatic recharge function test

Perhaps due to the consistent nature of electronic products, many people are worried about the endurance problem of sweeping robots. However, those who have used it must all know that sweeping robots will generally have an automatic recharging function. When the sweeper is about to run out of power, it will automatically Look for a charging cradle to charge without having to think about controlling or manually charging it.

It is worth mentioning that due to the unique map navigation function of Covos DR95, after exploring the terrain of the room, the sweeping robot can remember where the charging is done, and once the sweeping task is completed or almost dead, Kewo The DR95 can return directly to the charging cradle without having to repeat the search for the charging cradle.

Summary: Cobos DR95 has a wealth of features, such as anti-drop, anti-winding, collision, automatic recharging function, etc., in addition to the essential cleaning effect, the impact of these functions on the use of experience is also very large, and It can also extend the service life of sweeping robots.

Noise and power test

Noise test

Noise is the most unbearable to most people. As a daily household appliance, noise control ability is absolutely an important factor in whether users will choose. According to the past, sweeping robots have not been very satisfactory in terms of noise control. We do not know whether Cobos DR95 will bring us a surprise.

Noise test

In fact, for the noise, the standards that everyone measures may be different. After testing, the Kovos DR95 has a noise test result of 56.9 dB. Therefore, it is not recommended to use the Cobos DR95 during breaks.

Power test

Power test

When the Covos DR95 was connected to the charger for charging, the instantaneous power was tested to be 17.48W, which is not as high as the author thinks. As far as life is concerned, the author has not been charged for such a long period of time. In addition, the automatic back-charging function is supported, and there is no need to worry about the battery life.

Summary: Cobos DR95 sweeping robot performs better in power consumption, power consumption is still relatively low, and supports automatic back-charge function, its endurance ability is completely unnecessary to worry about. It is an acceptable range for noise control.

Summary: As the heavyweight product launched at the end of the year, Cobos DR95 will be fully marketed next year, allowing more consumers to experience higher-tech smart sweeping robots. The biggest difference between the Cobos DR95 and the previous products is that he uses the newly developed Cobos Smart Navi global planning technology, LDS laser radar scanning equipped with SLAM algorithm, scanning home layout, powerful home environment recognition capabilities, before cleaning Draw a home map first to ensure that the sweeping robot is more efficient, more comprehensive, and more intelligent at work.
