What factors that affect the robot vacuum noise ?

There are many factors that effect the noise of robot vacuum. which can be roughly divided into two parts.

First Factor: The Design Of Air Duct & The Way Of Noise Reduction

When robot vacuum is turned on, there will be noise. so many people think the noise is com from motor. but actually  the motor is silent. the noise is generally made when the turbofan agitates the air, but this kind of noise cannot be avoided on a single unit. so at present there is no robot vacuum quiet enough.

Different manufacturers have different ways of dealing with air duct design and noise reduction. we can have three conclusions

  • The smoother the air duct, the lower the wind resistance
  • The length of the air duct is moderate, and there is a certain distance to make part of the noise offset
  • The noise reduction material of the air outlet should be sound-absorbing and breathable, and so it won’t affect the exhaust and ventilation

For this factor, it’s hard to be controlled & adjusted by your self. choosing a good manufacturer & supplier is very important when you want a quiet robot vacuum.

With the increase for service life of the sweeper, the noise will be get louder. because there is inevitable wear and tear inside machine appeared. such as the gear wear, gears can’t rotate smoothly, then the noise will be louder than usual.
