Is There A Quiet Vacuum Robot?

The sound of flowers blooming is 10 decibels, 20-40 decibels is the ticking of an alarm clock, 60-70 decibels is the sound of a household hair dryer and electric fan, 70-80 decibels is the sound of the subway starting, and 90 decibels is the sound of a car whistle. The human ear will feel very noisy when hearing a sound above 70 decibels, while the noise of traditional vacuum cleaners is always reaching above 70. That is mainly because large suction power often means there is a noise problem.

Different Decibels

But robot vacuums have grown in popularity in recent years to automate the chore of cleaning floors. Generally speaking, the maximum noise of most quiet vacuum robots is about 60 to 70 decibels.

Robot vacuums produce much less noise than conventional vacuum cleaners,but when this noise comes from a constantly moving robot, it can be even more annoying. So is there a quiet robotic vacuum?

At present, the major manufacturers of vacuum robots are trying to reduce the noise as much as possible, trying to create a quiet robot vacuum cleaner, but in any case, it is difficult to achieve, at least the current level of technology can not do it.

Why There Is Seldom Quiet Robot Vacuum?

This is mainly because for the vacuum robot, being able to clean the floor is the ultimate goal, and strong suction is the key to ensuring that the garbage and dust can be sucked away. But on the other hand, high suction just means noise problems.

There are several reasons:

First, motor vibration, in theory, the motor is silent, but there must be errors in the process of manufacturing the motor. Therefore, when the motor is running, the rotor itself will vibrate and resonate to a large extent. However, this noise is less, not the main factor.

Second, fan blades vibrate, and sweeping robots generally use centrifugal fans to generate negative pressure. But no matter what kind of fan it is, there is bound to be an act of "breaking" the air. When "breaking" the air, the fan blades will make the airflow, hit, rub, and generate turbulence, and the fan blades will also be resisted in different directions. Make the fan blades vibrate and make a noise. This is the main reason why there is no quiet robot vacuum.

Last, air vibration. The rotation of the fan blade will cause the air to flow, impact and rub, and the collision and friction between the air and the air itself will also generate vibration and form noise.

In addition, every machine has aging problems, and the same is true for vacuum robots. Even a quiet robot vacuum, with the increase of the service life of the sweeper, the aging and wear of the machine parts will become more and more serious, and the noise will become more and more loud. Because of the inevitable wear and tear that occurs inside the machine. So noise is unavoidable.

Not only that, robot vacuum cleaner manufacturers need to choose between noise and cleanliness, and in order to ensure cleanliness, many manufacturers will put noise behind them. This is why there is no silent robot vacuum cleaner.

How To Pick A Quiet Vacuum Robot? 

1. Usually, the seller will directly mark the decibel when the vacuum is working on the product page. The noise is not very noisy within 70dB. For example, the Neakasa NoMo N3 Robot Vacuum Cleaner, a quiet robotic vacuum, produces less than 65 decibels of sound during operation.Quiet Robotic Vacuum2. Select a robot vacuum that can be controlled by the app, avoid rest time, and start cleaning the room in advance.
3. Select the quiet vacuum robot with a mature navigation system. Some vacuum robots sweep the floor at random, and they have to hit some obstacles to change direction. If such vacuum robots are allowed to clean the ground, there will be a banging sound from time to time, and more noise will be made.

    How Can I Make My Quiet Robot Vacuum Quieter?

    When you buy a robot vacuum cleaner, the motor and accessories cannot be replaced, and the internal structure of the robot vacuum cleaner cannot be optimized.

    But we can do maintenance work to delay the ageing and wear of the sweeper, reduce the noise when the vacuum robot is running, and keep it quiet for as long as possible.

    Reduce Airflow Obstruction

    Then, we should regularly clean our silent robot vacuum cleaner, especially the dust bag. This can effectively reduce airflow obstruction and also reduce certain noise.
