By using AI cleaning robot “whiz”, it is found that the number of airborne bacteria can be reduced to about 1 / 5.
Softbank robotics and Kumagai Gumi jointly conducted a field survey to evaluate the cleaning ability of AI cleaning robot “whiz”.
As a result, when using “whiz” for floor cleaning, it was confirmed that “the number of bacteria in the air can be reduced to about one fifth” compared with manual cleaning. In addition, a correlation was found between “floor cleaning conditions” and “cleanliness in the air (amount of suspended bacteria)”, and it was confirmed that keeping the floor clean can also increase the cleanliness of the whole indoor space. Therefore, it has been found that effectively removing the “hidden dust” that “wiz” cannot be removed by human cleaning helps not only to keep the floor clean, but also to keep the indoor space clean. Someone said.
In the investigation, the floor cleanliness of the two office buildings was tested by ATP (pollutant) wiping test, and the number of indoor floating bacteria was measured by microbial sensor bm-300c. The cleaning conditions during cleaning were compared.
The results showed that there was a correlation between the floor cleanliness and the number of floating bacteria in the two office buildings. Using “whiz” can reduce the degree of biological pollution (ATP measurement: RLU) by about 2000 to 4000. It is found that by continuing to use “whiz”, the floor surface can be kept clean without returning to the measured value before use.
In addition, the number of indoor floating bacteria (n / m3) during manual cleaning is 20000 to 30000, which is a relatively clean indoor space. However, after cleaning with “whiz” for 2-3 days, the number of floating bacteria in the room is reduced to 4000 to 6000 (about one fifth), and becomes a very clean indoor space, far less than 10000.
