The quietest robot vacuum cleaners you can lay your hands on right now

As you may have noticed, many manufacturers are far from forthcoming with the noise levels of their vacuum bots. That’s why we have felt the need to help you find the quietest robot vacuum cleaner on the market today.

Quietest robot vacuum time-lapse in living room

If you’re in a hurry, the RoboRock S5 from Xiaomi at 54DB (on its lowest setting) is the most quiet robot vacuum that you can buy. It might not have the cachet of the infamous Roomba by iROBOT, but it certainly delivers. The Roborock S5 is equipped with laser navigation, floor-mapping, and even a mopping function.

One of the key factors (often overlooked) of a robot vacuum cleaner is its noise output. What is the point of owning a vacuum robot packed with features if it disturbs the family every time you use it?

Why should I care?

  • You will be able to vacuum without feeling stressed by the noise. Many studies have shown that loud noise increases levels of cortisol in our bodies. Loud noises such as traffic, arguments, and noisy robotic vacuum cleaners will only make your anxiety levels rise.
  • Your cat or dog will thank you if you buy an ultra silent vacuum cleaner. If you are a pet owner, you are well aware of the distress that a noisy vacuum cleaner brings to their lives. Dogs and cats have very sensitive hearing and they are easily spooked by loud noises. It might sound like a gentle hum to you but it sounds like Armageddon to your Cocker Spaniel!
  • You will have the freedom to vacuum at any time of the day or night. The most silent robotic vacuums allow you to clean your crib at any hour of the day or night without receiving a barrage of complaints from your kids, neighbors, pets, or partner!

How do you define quiet in a robot vacuum?

In researching this article, we set out to find the quietest vacuum cleaning robots available today.

(Please note that there may be marginally quieter vacuums around but they didn’t make the list due to a lack of quality or poor after sales service.)

Our mission was to get the perfect balance between noise levels and usability.

By choosing any of the quiet robot vacuums in this article, you won’t disturb anyone, and you’ll also clean your crib effectively and efficiently.

Before you spend your hard-earned dough on a new robot vacuum, you might be wondering how much quieter “quiet” models are compared to “standard” vacuum cleaners and if it’s worth it to make the switch.

As a guide, most normal upright home vacuum cleaners emit sound between 75 and 80 DB (decibels). For quieter models, the sound output is closer to 65 – 70 DB.

The robot vacs featured in this article range between 54 and 70 DB so you would be hard pushed to find anything quieter while still getting a top-notch cleaning experience.

Quietest Robotic Vacuum – Xiaomi Roborock S5

Sound level – 54 Decibels

The most quiet robot vacuum cleaner - Roborock s5

This stealthy robot vacuum is top of our list as it is both the quietest and delivers awesome suction (even on first power setting). The RoboRock from Xiaomi is a very efficient noiseless bot with the lowest sound emission of 53 DB.

If you need more suction power (up to 2000 Pa), you can crank up the unit but of course, it will be slightly louder in volume. This high power setting is great for every kind of surface from wooden floors to carpeting.

The Xiaomi RoboRock S5 looks very similar to the previous model with only a couple of changes to the layout. The biggest addition is that it now has a mopping function which allows your vacuum robot carry out a dry and wet clean in one session.

At the front of the machine you will find a small water tank and the rear of the unit, there are brushes for dry cleaning. The Mi vacuum is fitted with two speakers, a dust collection tray, and Wi-Fi reset buttons.

The Xiaomi’s superior cleaning ability is thanks to a rotating brush that is very effective at siphoning dust & dirt into the path of the robot. Under the machine, there’s a circular brush which sucks in the dirt.

It has two wheels on either side and a smaller balancing wheel for great stability and a 2cm obstacle clearance, meaning that it can easily glide over rugs and any other uneven surfaces. We really love the “carpet mode” which increases suction when your vacuum recognizes it is cleaning a carpet.

The S5 vacuuming robot uses a clever grid-based cleaning system. In divides your room into zones and then glides backward and forward until the entire space is “spick & span.” The standard cleaning mode is ‘Balanced”, but you also have “Quiet”, “Turbo”, and “Max” settings should you need more suction. (Please note that in the top mode, the machine is noisier than when in its default setting.)

Cleaning is very straightforward with the Xiaomi RoboRock robotic vacuum. Just kick things off by pressing the power button and the robot comes to life. It has an impressive total of 12 sensors which help it to create a virtual map of your house. While cleaning, the robot maintains its proximity to walls at 10mm and thanks to the 2mm rubber bumper, your furniture is safe from potential damage.

The vacuum has a 5200mAh battery which is good for around an hour of cleaning time. When your cleaner runs out of juice, it will trundle back to its charging dock to recharge. It automatically resumes cleaning from where it left off.

The Xiaomi RoboRock robot vacuum cleaner is a very versatile machine. You can change the volume level, install new language packs, set automatic cleaning schedules, view your detailed cleaning history, and even get details on any maintenance issues that may arise.

You won’t need to worry much about maintenance, as the main filter and brush are washable and last for ages. The filter should be fine 150 + hours of cleaning time, and the brushes should not need changing until at least 300 hours of cleaning.

Not only is this machine the most silent robot vacuum, but it is also one of the best cleaning bots you can find for the money.

Runner-up – ECOVACS Deebot N79

Sound level – 55 Decibels

Silent vacuum - N79 Ecovacs

Not quite as quiet as the RoboRock, the Deebot N79 is an amazing machine and while being the runner-up, it’s easily one of the best robot vacuums available today.

The DN79 is a real bargain and the cheapest vacuum robot in this article. It has 3 cleaning modes and is fitted with state-of-the-art motion technology which enables the smart little fellow to optimize its routes to clean the entire floor (without missing any spots.)

The Amazon ECOVACS Deebot N79 comes with 2 side brushes which do a great job in dragging dirt and dust from the corners of your rooms and then directing the debris straight into the powerful suction port.

For the extra-lazy, the N79 has a remote control which enables you to change the cleaning modes and also to conveniently schedule your next cleaning session.

The Deebot is a super-quiet machine at just 55 DB (on the lowest setting) and an awesome choice for cleaning your man-cave or crib. It continues to be one of the best-selling automated cleaning robots with rave reviews from thousands of satisfied customers.

3rd place – iRobot Roomba 690

Sound level – 60 Decibels

Roomba 690 - Silent robot vacuum

The top end Roombas are certainly not cheap but this entry-level Roomba is a fantastic robot vacuum for the money and it performs just as well as other units costing twice the price.

Powered by iRobot’s now famous, iAdapt technology, the Roomba 690 is the quietest Roomba vacuum on the market at 60 DB.

The cool-looking Roomba navigates around any obstacles it comes across and is significantly more efficient than most regular dumb-ass robot vacuums.

The Roomba 690 can be controlled from your smartphone via the iRobot app and makes an excellent choice for small to medium sized cribs that wish to remain peaceful and stress-free!

While the 690 is the quietest Roomba, their best robotic vacuum cleaner in our opinion is the Roomba 980.

4th place – iRobot Roomba 780

Sound level – 60 Decibels

Vacuuming robot Roomba 780

The Roomba 780 is the newer version of the iRobot 770. The manufacturer claims that this Model will remove 98% of dust and dirt from any type of surface.

The main improvement over the 770 is the virtual lighthouse feature which confines the vacuum to one area and at a predetermined time, the unit will trundle off to clean a different room. The Roomba 780 is also equipped with a virtual walls function that allows you to keep the vacuum in or out of particular areas of your rooms.

A quick glance at the Amazon reviews shows that owners of the 780 are very happy with the way this device, particularly the way that it cleans all the way to edges of the room. This is thanks to the heavy-duty three-pronged side brushes.

Sufferers of allergies are also raving about the washable HEPA filters on either side of the dirt-bin which filter allergens up to a size of 0.3 micros. (Potential customers should note however that the HEPA filters need to be changed every 2 – 4 months to maintain their effectiveness if the machine is used on a regular basis.)

The officially stated runtime of the Roomba 780 is quoted by iRobot at 90 minutes but many customers claim to get up to 4 hours of use on a single charge. When the vacuum runs out of power, it takes between 2 and 3 hours before it is ready for more work.

All in all, the iRobot Roomba 780 is an excellent automated cleaning tool and a wise investment for those with busy lives.

5th place – iRobot Roomba 880

Sound level – 66 Decibels

Robo vac Roomba 880

The Roomba 880 was introduced by iRoomba as a replacement/upgrade over the Roomba 790 and among its many strengths, is one of the best robot-vacs for vacuuming animal or human hair.

Instead of the previously used brushes, the 880 is fitted with rubbery “extractors”. This brushless technology does an excellent job of removing dirt and also means less maintenance.

The Roomba 880 is 3.6 inches high, 13.9 inches wide, and weighs 8.4 pounds. Its features include a removable dustbin, a sturdy carrying handle, a simple release button, two side wheels, a removable caster wheel, dirt extractors, and a spinning side brush. The 880 also comes with a docking station, two virtual wall sensors, a remote control, and a spare HEPA filter.

When compared to the 780, the Roomba 880 is quicker, cleans better, and requires less maintenance. It’s also very easy to get the hang of, just choose between regular clean, spot clean, or set it up according to your own schedule and away it goes!

Many people choose the 880 as it’s equipped with Roomba Lighthouse. In Lighthouse mode, the device keeps the vacuum cleaning just one room first, then sends it on its way to clean the next room and so on. The Virtual Wall mode is a great way to keep the cleaner only in the rooms you wish to clean, and out of the ones you don’t.

Another great feature of the iRobot Roomba 880 is the patented AeroForce cleaning system. This involves rubber rollers instead of brushes. These spin around to increase airflow and provide excellent suction. These rubber rollers are much easier to clean than traditional brushes making the 880 a perfect choice for households with animals or people with long hair.

Frequently asked questions

back to menu ↑

How loud is loud?

A Decibel (dB) is the most common measurement of sound levels. The higher the number of decibels, the louder the sound will be.

If you’re wondering just how many decibels is too loud, a sound level of 60 DB is about the sound of a clothes dryer or a normal conversation.

The Xiaomi Roborock S5 is the quietest of the soundless robotic vacuums at just 53 DB. While that may be a little distracting when you’re watching TV, if you move to an adjacent room, you will hardly hear the sound of this quiet vacuum cleaner.

Are robot vacuums worth it?

Do Roombas work

iRobot is the leading manufacturer of robotic vacuum cleaners right now. Their range of robotic vacuum cleaners isn’t exactly cheap with prices starting at around $300 and rising up to the $900 mark.

The relatively high price point can put many people off buying one, especially when you bear in mind that they can’t perform all of the functions of a regular vacuum cleaner but whether a vacuum robot is worth the money really depends on how much value you put on your time.

The latest automatic floor cleaner machines can be programmed to clean-up your house every day leaving you free to get on with other things. Taking into account that most of us just seem to get busier and busier as the years go by, it’s no wonder that these cool cleaning devices are rapidly rising in popularity.

Even if they only save you a few hours a week, robot vacuums are great time-saving devices that can take care of the lion’s share of the vacuuming and they’re a wise purchase for anyone that struggles to find enough time to perform their cleaning duties manually.

For households that employ cleaning staff, a vacuuming robot will almost certainly be cheaper than human help and it will surely save you money in the long run, even more so for owners of very large homes that take a long time to clean.

What other factors should I consider when choosing a soundless robotic vacuum

It’s not easy to choose from the vast array of vacuums, so if you’re feeling a little confused about how to choose a robotic vacuum, you should consider these factors.

Apart from the noise level, there are a couple of other things to think about before you decide on the best model for you.

When choosing a soundless robotic vacuum, the main consideration is the kind of floor you will be cleaning most often. Do you need a unit for thick carpets, tiles, wooden floors or vinyl? While many of the latest autonomous vacuum cleaners can function on any surface, you are still well-advised to choose a Roomba which is actually designed for a particular floor type.

Another consideration is the type of material you wish to hoover. For example, some robotic vacuums are great for regular dirt and dust whereas others are actually designed to vacuum animal hair.

Other things you should check before making an informed purchase are the build quality, battery life, Wi-Fi connectivity, warranty and whether there is an app available. Robot vacuum apps are a great way to check on the vacuums status when you’re not at home.

Which robot vacuum is the best?

Do Roombas work well

If money isn’t a factor for you, the Roomba 980 is our pick for the best robotic vacuum available today! (you can see it at Amazon by clicking here)

While many of its competitors just aren’t good enough to pick up all of the hair and dust on carpets, the Roomba 980 is more than capable of getting your floors clean.

What makes this machine so effective are the rubber carpet agitator (which is second to none in picking up dirt and dust), and its awesome mapping system. The unit has excellent navigation abilities and hardly ever gets itself stuck.

The Roomba 980 is able to locate the dirtiest areas of your floor with its clever Dirt Detect system and is really head & shoulders above its many rivals. The only downsides of the Roomba 980 are the hefty price-tag and it’s also not the quietest robot vacuum in the world either!

If you want more information you can check out our article in which we investigate if robot vacuums are worth the investment.

Which Roomba is the quietest?

At 60 DB, the iRobot Roomba 690 and iRobot Roomba 780 produce the same noise levels with the Roomba 880 slightly louder at 66 DB.

The 690 is a great little vacuum for the money with direct detection and multi-surface brushes. Smart features include voice control with Alexa and Google Assitant.

For a little more dough, you can get better equipped 780 which is better on carpets and for dealing with pet hair.

Can a robot vacuum replace a traditional vacuum cleaner?

In most cases, not quite. Even the best robotic vacuum cleaners don’t have all the functions that top-of-the-range traditional upright vacuums usually have.

Where they do excel is that they will run as long as the battery has power and they are great at keeping your floors clean on a day-to-day basis.

By owning a robotic vacuum, you will save wear and tear on your traditional vacuum cleaner and most owners agree that owning one saves heaps of time and makes boring cleaning tasks a heck of a lot easier!

While robot vacuums are a great solution for regular floor maintenance, you will still require an upright vacuum for a deeper clean about every 2-4 weeks (depending on how grubby your home gets).

And it goes without saying, that robo vacs can’t climb stairs or remove dust from shelves, ornaments or car interiors.

Which robotic vacuum is best for pet hair?

Best vacuum cleaner animal hair - Roomba 980

Pet owners will tell you that they vacuum two or three times more often than folks that don’t keep animals in their home. This is because dog and cat hair can be a real problem – even more so for sufferers of allergies.

Yet again, the best solution for animal-lovers is the Alexa-enabled & Wi-Fi connected iRobot Roomba 980.

The 980 has tangle-free brushes which means that you don’t have to spend time cleaning the device, as is the case with most other models.

Another reason why the Roomba 980 is a great choice for pet owners is the omnidirectional virtual walls feature. This means that when using the Halo Mode, the vacuum has a no-go zone (measuring four feet in diameter) which ensures that the unit doesn’t go near your pet’s food/water bowls and more importantly the animal’s litter box.
