How Loud is a Roomba? (Comparing Noise Level of All Models)

Last updated on December 31st, 2023

It’s important to know how loud is a Roomba while cleaning because sometimes this noise can disrupt your day-to-day activities. There’s no specific noise level for Roombas. It varies from model to model and also depends on a number of factors. We will cover all these points in the article so you can determine how loud your Roomba can get.

A Roomba can make noise anywhere between 48 to 76 dB, depending on the model. All Roombas have their distinctive noise levels. They make more noise on hard floors than carpets, and they are noisiest while emptying their bins. Also, factors like their size, age, and maintenance make an impact on the Roomba noise levels.

We will compare the noise levels of different Roomba series and some of the most popular Roomba models. This will give you a rough idea of how loud your Roomba can get. All the given values are in decibels (dB). If you don’t know how much a decibel sounds, then refer to the next section, where you will get a clear idea.

Now let’s compare the noise levels of different Roomba models on hard floors and carpets and when they are emptying their base.

Roomba noise levels

From the table, it is clear that the Roomba j7 is one of the quietest Roomba models. You must have noticed that different series models have different noise levels. It is not possible to collect data about each and every model in each series, but the above table should give you a rough idea.

How loud is a decibel?

In the previous section, we have given all the noise levels in decibels (dB). It can get hard to imagine how loud a 70 dB Roomba can really get. So let’s try to simplify it for you.

The table below might give you some insights. We have grouped together a sound level and tried to find what other everyday scenarios you encounter that sound level.

Noise levelActivity
10-20 dBBreathing, rustling of leaves
30-40 dBQuiet rural area
50-60 dBNormal talking
70-80 dBCar, garbage disposal
90-100 dBAirplane, power lawn mower
Noise levels and activities

The Roomba j7+ emits a sound of 55 dB while cleaning the hard floor, which comes in the normal talking noise range. It can go as high as 76 dB while emptying its dustbin, which can be considered as loud, but the duration won’t be that long, as the emptying process ends up quickly.

Factors affecting the noise level of a Roomba

All Roombas don’t emit the same amount of noise. There are certain factors that determine how loud any vacuum would be. Some of those factors include:

  • Size of the Roomba
  • Age of the Roomba
  • Type of surface it is cleaning
  • And how it is maintained

Let’s see how each of these factors contributes to the noise level of a Roomba.

Size of the Roomba

The smaller your Roomba, the less noise it will create. Roomba models don’t differ drastically in terms of size, but some are smaller than others. For instance, the Roomba 600 series vacuums are smaller than the Roomba 900 series vacuums, so the 600 models should create less noise than the 900 models.

Age of the Roomba

The age really matters when it comes to the noise level of a Roomba. With constant wear and tear, old Roomba models have several sections that rattle during cleaning are create more noise. Because a few parts become loose and their ability to stay fixed is diminished, older Roombas create more noise. New Roombas are comparatively quiet.

Cleaning surface type

  • Roombas are much quieter while cleaning carpets than while cleaning tiles or hardwood floors. This is because carpets give a cushioning effect and muffle the sound of the Roomba.
  • On the other hand, Roomba’s noise is echoed with hardwood floors. So their noise level seems to be higher.

Roomba maintenance

It is extremely important how well you maintain your Roomba. We have seen people complaining that their new Roomba has started to create more noise than before. When in fact, these people were ignoring the regular maintenance of the vacuum.

If debris accumulates within the brushes or the motor, the Roomba will create loud noises. That’s one of the reasons you should regularly clean your vacuum.

Can the neighbors hear your Roomba?

From the shared experiences of several Roomba users online, we deduct it is very likely that the neighbors can hear your Roomba. You can confirm it by going outside your house and trying to hear the Roomba.

But the best option is simply to ask your neighbors. Go over, make friends, and ask them if they can hear your Roomba. If they mention that it’s too loud or disturbing them in any way, you can work out a schedule that suits both you and your neighbors. It’s always good to be considerate of others.

Noise reduction tips for Roomba

There are a few ways you can try to reduce the noise of your Roomba. It’s not going to make a drastic change to your Roomba volume level, but it will diminish the sound a bit. Remember, you have to employ these tips regularly to have the full effect. Doing it once and expecting the results is not going to make it. So let’s explore what you can do to reduce your Roomba’s loudness.

1. Clean the Roomba brushes

Brushes, may it be the rubber ones or bristles ones, will rattle and make creaking noises if there’s a lot of debris accumulated near the axles. Often hair gets wrapped around them, which creates a nuisance.

You have to take out the brushes and the yellow-colored brush caps on both ends to check for hidden debris. Clear everything out and put them back in. This should reduce the sound coming from the Roomba brushes.

2. Check the wheels

Wheels can make scrapping noises on floors if something is stuck to them or they are damaged. To prevent damage, you have to maintain them regularly. If damaged beyond maintenance, contact iRobot Customer Care for help and replacement. But if something is stuck to the wheels, you can clear it out.

Use Q-Tips and a small brush to reach inside the wheel and clear whatever you can. That should reduce the scrapping sounds.

3. Run at different times

If you feel your Roomba is creating a ruckus and disturbing your other activities, try to run it at a different time. You can ask it to clean when you are not home to avoid the noise completely. Or you can schedule it for a time when you are not doing anything important. It’s all about finding the balance and choosing an appropriate time slot so you have the least disturbance.

4. Check for loose parts

And the last tip for now – check if there are any loose parts on the vacuum. Pick up and shake your Roomba slightly when it is not running and look if anything is rattling. It could be because of some loose screws. Try to tighten and keep all your Roomba parts in place. This should actually create a difference in the amount of noise a vacuum makes.

Conclusion

Your Roomba can be as silent as normal talking and get as loud as a garbage disposal in use. It really depends on how you are using it.

The self-emptying of bin part is no doubt the noisiest. But still, their work on hard floors can bother people, especially if they are doing something important. If you feel your Roomba is too loud, use our given tips to try to lower its volume.

Even after employing them, if you don’t like the sound, then you might want to run it when you are not home or switch to a quieter model. You can view the sound levels of different Roomba models in the table above.
