Yesterday, China Consumers Association released a comparative test of 20 sweeping robots.
Electrical safety is generally no problem
Recently, the Consumers Association of China Consumers purchased 20 sweeping robot samples from the Beijing home appliance stores, JD.com, Suning.com and Amazon.com as ordinary consumers, covering sweeping coverage, cleanliness, and endurance. Comparison of aspects of performance testing. 20 samples purchased from the price of 799 yuan -7499 yuan.
The test found that in terms of electrical safety, there was no problem with the heat generation of the prototype, the leakage current at the working temperature, and the electrical strength. The samples purchased at home were more standardized. The logo and description of the LG-VR65502LV sample from two overseas purchases. There is no Chinese annotation, the contents of the tag of Botuo Botvac D8500 sample have been tested for persistence.
Price quality may not be proportional
However, different machine cleaning capabilities vary widely, but not necessarily proportional to price. For example, millet-mike SDJQRRR model robot, its sweeping coverage, floor cleaning, corner cleaning, hair cleansing performance in five stars, price is 1699 yuan. The price of a robot similar to iRobot Ai Robert's similar index is 7,091 yuan. FMART is a robot with 3582 yuan, sweeping coverage, floor cleaning, and corner cleaning. The three indicators are one star and three and a half. , Samsung.
In addition, some sweeping robots are 'sweeping and dragging one machine'. The mode used is the form of water tanks and water soaking rags. Due to the limitations of the body size, the water tanks are generally not very large. The rags are only lightly grounded for the ground cleaning. , Floating soil can be cleaned, if there is jam or other solid contaminants, little effect.
■ Test results
Significant difference in cleaning performance
Prototype with better cleaning performance, superior suction
Coverage tests are carried out in the space of the same specified area. Place tables, chairs, heating radiators, floor lamps, short-haired carpets, etc. in the test environment. Check the sweeping robots.
The test found that the coverage of the 20 prototypes was significantly different. Some of the samples were designed to prevent the machine from retracting the charging base. The design was that the periphery of the base was not cleaned by default; some of the more expensive samples also showed minor omissions; some of the samples were specified in this regulation. During the cleaning time, the omission was obvious, the coverage was low, and the cleaning power was also very different. Some samples had a clean rate of 93.34%, and some were only 29.63%.
According to the staff of the China Consumers Association, in the tests, the prototypes with better cleaning performance have superior suction power. The suction can be used as one of the reference conditions for judging whether the cleaning ability is excellent, but at the same time it should also be noted that some models are high. In the gear position, suction really increases, but noise increases.
However, when purchasing products on physical stores or e-commerce sites, it was found that some products only mentioned large suction power. However, it is not intuitive how much the suction value is. In the Consumers Association, it is hoped that the company will clearly specify the suction range or cleaning ability. Consumer purchase.
Hair cleansing ability is generally good
No main brush suction mouth less type winding
In the home, the fallen hair will fall on every corner of the house and it will be more laborious to clean. This comparative test uses a certain number of short hair and long hair for sweeping test. After brushing, the prototype rolls, side brush and dust collector. The length of the medium, the number of short hair counts, the calculation of the cleanliness rate. The cleanliness rate of the 20 samples was above 80%, and the performance was good.
In addition, for families with pets, whether pet hair that is lighter than hair can be successfully cleaned, whether hair is blown everywhere during work, or whether winding is serious is an important indicator to consider.
The test used a test article that was very similar to pet hair. Each time a test piece of 0.5g was used, each model was tested three times and the weight of the cleaned hair was weighed. The higher the cleanliness the better, and the lower the better the winding rate. The test results showed that the pet cleaning rates of the 20 prototypes were all relatively high, both higher than 89%.
According to the staff of the China Consumers Association, for the hair and pet hair cleanup, the winder type winder with no main brush rarely occurs, but the side brush is also likely to be wound, and the overall cleanup is easy. The main brush type , Although the cleanliness rate is also very high, but the roll brush will have winding problems, cleaning up a little tedious.
When work is too large
Individual sample noise reaches normal cleaner noise
For people, the optimal living environment should not exceed 45 decibels. In this test, the model with the lowest average noise level is about 53 decibels. Some models are equipped with a high-range mode, with greater suction. , But the noise is even greater, the individual sample noise reaches about 72 decibels, reaches the noise of the ordinary vacuum cleaner.
In the analysis of the Consumers Association, the noise of the sweeping robot was too large during operation. This was due to the use of a high-speed rotating fan to generate dust under negative pressure. Therefore, the noise cannot be reduced to a very low level.
In addition, whether or not the obstacle crossing capability is powerful will also affect whether the sweeping robot can work smoothly. During the test, only a small number of models can clean the mid-sized wool carpets. Some of the opportunities are entangled by cables, and some even appear as side brushes. In case of being stuck out, the prototype with anti-winding function is said to perform well. When passing through the gap at the bottom of the radiator, which is 10 cm high from the ground, there is an occasional chance of being stuck. The metal base of the lamp, For the body without collision detection function will form different degrees of scratches.
■ Consumption tips
Buy sweeping robots should be selected models on demand
If you want to focus on cleaning hair, pet hair, you can choose a good suction, and use the model of suction mouth, you can save the steps to clean the machine roll brush. Some sweeping robot can switch between the roller brush and suction mouth. Roller brush form Sweeping robots can also clean the hair well. However, it is still necessary to clean the airframe. It is relatively easy to clean it up with a brush-type machine. If it is focused on cleaning dust and particles, you may choose to use a roller brush. The coverage rate is high and the cleaning rate is high. And suction strong models.
When buying, pay attention to the capacity of the dust collector of the sweeping robot. Too small dust collectors need frequent cleaning to affect their normal work. The sweeping robot cannot clean up to every corner of the house. Therefore, it is not purchased a sweeping robot. Do not clean up.
At present, many sweeping robots have used the HEPA filter at the air outlet, which has a good effect on the filtering of fine dust. At the time of purchase, pay attention to the design of the outlet direction of the machine, otherwise the strong wind at the rear air outlet may be Uncleaned dust on the floor, dirt blowing, causing secondary pollution. Many products on the market have put the wind direction of the outlet upwards, avoid blowing the ground directly, consumers should choose this kind of product as far as possible.
