So, what is the performance of such a sweeping machine that integrates face value and workmanship? We immediately entered the measured part.
Cleaning effect test
Test item 1: sweeping oats
Test site: Range of activities of 2m x 2m on a wooden fence
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.
Test results: About 2 minutes and 24 seconds after the cleaning was completed, 29 grams of cleaned oats were weighed, which was almost equal to that before the test. The cleaning rate was as high as 99%, so the neato BV-D7500 passed easily 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.
Test results: After a period of about 2 minutes and 04 seconds of cleaning, all mung beans in the dust box were collected and reweighed to 29 g. Therefore, the neato BV-D7500 was passed at a 99% sweep rate in this test.
Sweep coverage test
The family environment is generally relatively large and complex. Many people will worry about the intelligence of the robots, and they are afraid that they can't clean their entire area. This involves the sweeping coverage rate of sweeping robots. Therefore, the editors clean up a place in the evaluation room to simulate daily homes. Environment, and set 6 places marked oats to see if the neato BV-D7500 can be fully cleaned. (The video is processed by accelerated playback in about 2 minutes)
Test results: In this test, neato BV-D7500 once again proved its own strong strength. In the shortest time (about 11 minutes), the sweeping range covered every place and it was cleaned almost once. Also, as can be seen from the video, the neato BV-D7500 not only excels in cross-country climbing but also benefits. With powerful navigation technology, even the complex terrain on the bottom of the sofa and coffee table will not be lost.
Summary: After three rounds of sweeping tests, whether it is cleaning mung beans, oats, or indoor home combat, the results of neato BV-D7500 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. However, from the above sweeping test videos, we can see that the neato BV-D7500 has a very good edge-sweeping thinking, so that the edge of the corner is no longer a blind spot for 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 editors simply put a path in the evaluation room, trying to trap the neato BV-D7500 and see if the editor had 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, neato BV-D7500 is not so unobstructed.
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.
Summary: neato BV-D7500 has a wealth of features, such as anti-drop, anti-winding, automatic recharging function, etc., in addition to the essential cleaning effect, these features have a great impact on the use of experience, but also very Good to extend the life of sweeping robots.
Noise and power test
Noise test
Decibel level
0-20 dB is very quiet, almost 20-40 decibels quiet, like a 40-60 decibel whisper, normal indoor conversation 60-70 decibels noisy, destructive nerves 70-90 decibels noisy, nerve cell damage 90 -100 dB loud noise, 100-120 dB impaired hearing loss, irreparable deafness for a minute or more that is temporarily deaf to 120 dB or more, or around 300 cm or above, or 20 km above.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 neato BV-D7500 will bring us a surprise.
In fact, for the noise, the standards that everyone measures may be different. Perhaps due to its own strong suction and power, the noise test of the neato BV-D7500 has been tested to 59.4 dB, so it is not recommended to use the neto BV-D7500 during breaks. However, compared to previous generations of products, the neato BV-D7500 has achieved great progress in controlling noise while continuing its powerful power and suction.
Power test
When the neato BV-D7500 is connected to the charger for charging, the instantaneous power is tested to be 37.15W, and since it is fully charged, it only takes about 2 hours, so power consumption is not too much. 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: Some people think that neato BV-D7500's power consumption is a bit high, but the editor believes that the advantage of high power is the short charge time, compared to those low power but long charging time sweeper, in fact, both It is also basically the same, and the neato BV-D7500 takes up the advantage of quick charging, and supports the automatic recharging function. Its endurance capability is completely unnecessary to worry about. It is an acceptable range for noise control.
Summary: neato BV-D7500 adopts a disc shape that is different from traditional sweepers. The innovative use of "D" right-angle design is to ensure that it can better clean the 90 degree corners and other difficult sweep positions. Appearance color is mainly white + blue + black, using physical button + touch button design, the overall feeling of simple and generous, people love at first sight.
