Does the noise of the sweeper disturb people?

The sweeper is driven by pure electric power and adopts the principle of roller brush combination. High efficiency and no noise when cleaning dust. It is impossible to say that there is no sound at all, but when normal people communicate with each other, their voices are similar. If residents can hardly hear the sound of the machine turning indoors, it is not a problem of disturbing the people.

Just like the new energy electric vehicles that are very popular now, we often see new energy vehicles in the community. There is no noise during its formation. It's all about driving cars, and there won't be much noise. This is also recognized by many enterprises and companies, because the property company will consider this when buying a sweeper again. So, does the noise of sweeping cars in the community disturb people? This doesn't exist.
