Judging from the current scientific evidence, neither the fruit and vegetable washing machine nor the fruit and vegetable disinfection machine is an effective equipment. Although it may play a certain role in some specific circumstances, it is of little value in general. Neither the cleaning machine nor the sterilizer really answered the key question of removing and degrading pesticide residues in principle.

Yi Zhu, an associate professor at the College of Food Science and Nutritional Engineering of China Agricultural University, said that there are many kinds of pesticides used in reality, and different pesticides have different principles in preventing and controlling pests and diseases. Therefore, a sterilizer with only one function can't be "one person guarding ten thousand people can't be forced", and it can't effectively remove pesticide residues from all fruits and vegetables.
Moreover, in the advertisements of various vegetable washers, manufacturers always come up with a bunch of "authoritative test reports" and various dazzling experiments. However, this is all a scam that takes advantage of consumers' lack of professional knowledge.
For example, some manufacturers claim that the degradation rate of pesticides can reach a fairly high level. In fact, they added a specific pesticide to the water and measured the amount of pesticide after treatment, thus obtaining a high "degradation rate". In fact, this pesticide does not represent the pesticides that may actually exist on fruits and vegetables. The state of pesticides in water is completely different from that on fruits and vegetables.
At the same time, the current vegetable washer market is also very chaotic, with enterprises of different sizes and uneven product quality, and the phenomenon that merchants exaggerate product functions at will is everywhere. Some experts said that the diversity and irregularity of technical schools are common problems in China's vegetable washing industry.
