I work from home, and I don’t know about you, but when my Roborock S7 starts up, it always feels like it’s in the middle of an important meeting with my CEO. It’s loud, and it’s a real distraction. Meetings aren’t the only reason to want a quieter robot, either: if you watch TV while it cleans, have a baby who naps, or run it at night, the noise matters too.
So what’s the quietest robot vacuum, measured with a meter rather than promised on the box? The Roborock Saros 10R: it measured 50 dB while cleaning in TechGearLab’s tests, about the level of a calm conversation across the room. If that’s more than you want to spend, the MOVA P10 Pro Ultra measured 53.3 dB at a mid-range price, and the Roborock Q7 M5+ stays under 56 dB for under $500.
What’s new (October 2026): every pick has changed. The old list was older models with decibel figures nobody could source, so this is now five current robots ranked by measured decibels, plus a new section on the noisiest part of any robot vacuum: the dock.
None of these five has lived in my house, so for each one I’ve read TechGearLab’s lab measurements and reviews, what owners report in Amazon’s review summaries, and the makers’ own claims, and checked in October 2026 that each one is still listed on Amazon. (how I choose)

How loud is “quiet”? Decibels in plain English
Decibels (dB) work like a staircase where every ten steps up sounds about twice as loud, according to HyperPhysics, Georgia State University’s physics guide. So a robot at 50 dB isn’t a little quieter than one at 60 dB; it sounds roughly half as loud. That’s why a few decibels on a spec sheet matter more than they look.
For everyday comparisons, TechGearLab puts most robot vacuums at about 50 to 65 dB while cleaning, the range of a normal conversation or a dishwasher. Self-emptying docks climb to 70 to 80 dB, which is vacuum cleaner, traffic or noisy restaurant territory.
No robot vacuum is silent. The motor, the brushes and the wheels all make noise, so “silent robot vacuum” on a listing really means “quieter than the last one”. The useful question is how quiet, measured how.
That’s the catch with makers’ numbers. Narwal’s own blog says its Freo X Ultra runs “at just 33 dB”. TechGearLab put a meter next to it and got 53.8 dB, so by the staircase rule the blog is claiming a robot about four times quieter than the one that turned up. Maker figures usually come from the quietest mode under conditions you can’t check, so on this page I use one set of measurements taken the same way for every robot.
Here’s how the picks compare, measured by TechGearLab on standard suction:
| Robot | While cleaning | While the dock empties | What it sounds like |
|---|---|---|---|
| Roborock Saros 10R | 50.0 dB | 66.4 dB | A soft wind-like hum |
| MOVA P10 Pro Ultra | 53.3 dB | 67.8 dB | A gentle, hollow whirr |
| Narwal Freo X Ultra | 53.8 dB | No emptying dock | Quiet, with no loud emptying cycle |
| Roborock Qrevo S5V | 54.7 dB | 66.0 dB | A steady low hum that’s easy to tune out |
| Roborock Q7 M5+ | 55.7 dB | 71.4 dB | A constant whirr, plus a few dings |
| iRobot Roomba Combo 10 Max (for comparison) | 58.1 dB | 77.6 dB | Noticeably louder on both counts |
The dock: the loud part nobody prints on the box
A self-emptying dock sucks the dust out of the robot’s bin and into a bag, and that blast is the loudest noise any of these machines make. On every pick here with an emptying dock, the dock measured 11 to 16 dB louder than the robot in TechGearLab’s tests: the Saros 10R hums at 50.0 dB, then its dock empties at 66.4 dB. By the staircase rule, that’s two to three times as loud, which is how a robot that hums quietly can still have a dock that sounds like a hair dryer having a bad day.
The good news is that TechGearLab found most of the emptying cycles brief. If the dock is what bothers you, the Narwal Freo X Ultra squashes the dust into a bag inside the robot and never does a loud emptying cycle. The Roborock Q7 M5+ goes the other way: its dock is the loudest of the five at 71.4 dB, but it only empties when the robot’s bin is full, and TechGearLab found the cycle very quick.
The quietest robot vacuums, pick by pick
Roborock Saros 10R (quietest overall)
Maker Roborock, a robot vacuum maker based in Beijing · For Light sleepers and home offices with a bigger budget · Runs on Rechargeable battery, about 180 minutes per charge
A robot vacuum and mop that measured 50.0 dB while cleaning in TechGearLab’s tests, the quietest of the 23 robots in their comparison. Their testers described it as a wind-like hum that wouldn’t wake a sleeping baby, and the dock’s emptying cycle as brief and more mechanical than harsh.
It’s also only 3.14 inches tall, because it skips the raised laser tower most robots wear on top and uses 3D sensing instead. Think of the tower as a periscope: the Saros manages without one, so it can duck under sofas and beds that other robots bump into. It still avoided every obstacle TechGearLab put in its way, including cords, shoes and a fake pet mess.
The dock washes the mop pads with hot water, dries them with warm air, refills the robot’s water and holds about 60 days of dust. TechGearLab’s testers said they could mostly forget about it until the dust bag and the water station needed attention, which is still a job: filling the clean-water tank, emptying the dirty one and changing the bag. Its mopping was the best TechGearLab had seen. Pet hair is the weak spot: it picked up only 56% of the hair in their test, and fine grit tends to get lifted to the top of the carpet rather than removed.
Privacy: it has a camera and a microphone for pet video calls and the “Hello Rocky” voice assistant. Roborock says the robot doesn’t record audio or video, video calls are off until you press a button on the robot and enter a password in the app, the video is encrypted, and you can switch the camera and microphone off. Photos it takes of obstacles are stored, encrypted, on the robot itself. Roborock also lists security ratings from TÜV Rheinland and UL, outside labs that check a connected gadget the way a home inspector checks a house, but they’re not confirmed for this model.
What owners say: In Amazon’s review summary, owners praise the mapping, the navigation and the easy setup, and most think it was worth the money. Cleaning and obstacle avoidance get mixed comments, with some saying it misses obvious dirt, and some report units failing after about 13 months.
Skip it if you have a long-haired dog and mostly carpet, because pet hair is its weakest result. The catch: you pay flagship money, and a camera robot is a privacy call only you can make.
MOVA P10 Pro Ultra (best value)
Maker Mova, a lower-priced sub-brand of Dreame · For Tidy homes that want a quiet, full-service robot · Runs on Rechargeable battery, up to 2.5 hours per charge
A robot vacuum and mop with an all-in-one dock that measured 53.3 dB while cleaning and 67.8 dB while emptying. Only three of the 23 robots in TechGearLab’s comparison measured quieter while cleaning, and one of them is the Saros above. TechGearLab made it their pick for most people and described the sound as a gentle, hollow whirr.
The dock does nearly everything: it empties the robot into a bag that lasts about 75 days, washes the mop pads with hot water and dries them with warm air. On hard floors it picked up about 91% of TechGearLab’s test mess, and it handled fresh spills well, though dried-on stains needed a second pass.
Its weak spot is finding its way around clutter. TechGearLab found it marks obstacles correctly on its map but doesn’t always respond to them in real time, and in testing it ran straight into a fake pet mess. Picking up socks and cables before it runs is part of the deal. There’s also a newer Gen 2 on Amazon with a bigger suction claim; TechGearLab tested this original.
Privacy: it has a camera for spotting obstacles and for pet video calls. Mova says app data is stored in your region’s data center (it runs them in the US, Germany and Singapore), and its website policy says some data may be processed in Singapore and China. I found no independent security certification, so leave the video-call feature off unless you’ll use it.
What owners say: In Amazon’s review summary, owners say it cleans well, maps rooms quickly and is easy to set up, and they rate it as well worth the price. Some even praise its obstacle avoidance, which TechGearLab found hit and miss, so expect a tidier floor to give you the better experience.
Skip it if your floors are a minefield of cables and dog toys. The catch: pet hair gets pushed around more than picked up, and its exhaust can blow light fluff away.
Narwal Freo X Ultra (no noisy dock emptying)
Maker Narwal, a Shenzhen robot mop maker founded in 2016 · For Pet homes and anyone the dock roar would bother · Runs on Rechargeable battery, about 210 minutes per charge
A robot vacuum and mop that measured 53.8 dB while cleaning, and the only pick here with no loud emptying cycle at all. Instead of a dock that blasts the dust out, the robot squashes it into a small bag inside itself, like a trash compactor riding along, and the bag lasts about seven weeks.
The dock still washes, dries and refills the mops, so your main jobs are swapping that dust bag every seven weeks or so and looking after the dock’s water. TechGearLab found it the best robot at pet hair: it picked up over 90% of the fur in their test and, in their words, prevented clogs and tangles in the brush roll.
It does have a couple of quirks. It’s 4.5 inches tall, so it won’t fit under low furniture, and TechGearLab found it struggled with edges and corners, ran over a fake pet mess and sometimes stopped mid-clean.
Privacy: no camera; it sees obstacles with lasers, so there are no photos of your home. It needs a Narwal app account for maps and schedules. Narwal says your Wi-Fi password stays on the robot and phone, and you can delete the robot’s data from Narwal’s cloud by cancelling the device’s authorization.
What owners say: In Amazon’s review summary, owners say it cleans well and is worth the money, and they like how little looking after it needs. The mapping and the app get mixed comments.
Skip it if you have a puppy that has accidents, because it won’t steer around them. The catch: “no emptying dock” also means you’re the emptying dock, every seven weeks or so.
Roborock Qrevo S5V (best mopping for the money)
Maker Roborock, a robot vacuum maker based in Beijing · For Hard-floor homes where mopping matters as much as quiet · Runs on Rechargeable battery, about 180 minutes per charge
A robot vacuum and mop that measured 54.7 dB while cleaning, which TechGearLab called one of the quietest they tested: a steady, low hum that was easy to tune out over time.
Mopping is where it shines. Two spinning mop pads scrub the floor, and in TechGearLab’s test it cleaned up all of a dried coffee spill. The dock empties the robot, washes the pads, dries them with warm air and refills the water tank.
Obstacles are its weak spot. It uses a pattern of light to spot things in its way, a bit like feeling around a dark room with a flashlight, but it avoided only half of TechGearLab’s obstacles and hit four of six fake pet messes. It also left a thin trail of fine sand on hard floors.
Privacy: no camera; it spots obstacles with structured light. It uses the Roborock app and account, and Roborock’s privacy commitments above apply.
What owners say: In Amazon’s review summary, owners say it keeps floors spotless, maps well, has an easy app and runs quietly. Value and reliability get mixed comments, with some saying obstacle avoidance misses things and some reporting units that stop working.
Skip it if you won’t pick up cables and pet bowls before each run. The catch: the robot is quiet but the dock empties with a high, windy whoosh, like a strong fan.
Roborock Q7 M5+ (best under $500)
Maker Roborock, a robot vacuum maker based in Beijing · For Apartments and hard floors on a tighter budget · Runs on Rechargeable battery, about 150 minutes per charge
A budget robot vacuum and mop that measured 55.7 dB while cleaning, still quieter than every Roomba TechGearLab tested. It navigates with LiDAR, the little spinning laser on top that maps the room the way a bat uses sound, so it cleans in neat rows instead of bumping about.
Its dock is the loudest of the five, at 71.4 dB, but it only empties when the robot’s bin is full, and TechGearLab found the cycle very quick. The sealed bag holds about seven to nine weeks of dust. The robot itself makes a constant whirr and a few digital dings that take some getting used to.
It’s best on hard floors, where it picked up 79% of TechGearLab’s test mess and handled heavy, dark stains well when mopping. Carpets were weaker at 57%. It ran over almost everything left on the floor, got stuck a few times, and didn’t always tell the app it needed rescuing.
Privacy: no camera; it uses a laser to map. It needs a Roborock app account, and Roborock’s privacy commitments above apply.
What owners say: In Amazon’s review summary, owners say it does well on hardwood, the app is easy and maintenance is simple. Some report the battery stopping charging after six months, and several say the mop stopped working after about three months.
Skip it if you share your home with a long-haired pet, because hair wraps the brush and can take ten minutes to cut out. The catch: mopping means filling the tank and fitting the pad by hand, and quiet on a budget means tidying first.
What about Roomba?
If you searched for the quietest Roomba, here’s the short answer: TechGearLab measured three, the Combo 10 Max, the i3+ EVO and the QO120, and all three landed within half a decibel of 58 dB. There isn’t a quiet Roomba so much as a Roomba volume. That’s about 8 dB louder than the Saros 10R, which by the ten-steps rule sounds close to twice as loud, and the Combo 10 Max’s dock hit 77.6 dB.
If you like the idea of a Roomba but want something quieter, my Roomba alternatives for every budget go through the options.
How to make any robot vacuum quieter
- Schedule it for when you’re out. The quietest robot is the one cleaning while you’re at work, and every app lets you set a schedule.
- Use the lower suction settings. Turn the suction down for everyday cleans and save full power for carpets, and set a do-not-disturb window for the evening.
- Put the dock somewhere sensible. A hallway or utility room beats the corner of the bedroom, because the dock is the loud part.
- Pick up first. A robot chewing on a phone cable makes a racket and needs rescuing, which is noisier than any motor.
- Keep the brush clear of hair. A tangled brush is a struggling brush, and pet hair was the weak spot for four of these five in TechGearLab’s tests.
What they cost to run
All five need replacement parts over time: dust bags, mop pads, filters and brushes. The makers state how long a dust bag lasts (about 60 days for the Saros 10R, 75 days for the MOVA, 10 weeks for the Qrevo S5V, seven to nine weeks for the Q7 M5+ and seven weeks for the Narwal’s bag inside the robot), but I couldn’t find a published replacement schedule or prices for the pads, filters and brushes on any of them, so check the app’s reminders once you own one.
The mopping docks also need water duty. On the MOVA you fill a 4.5-liter clean-water tank and empty a 4-liter dirty-water tank, and TechGearLab notes both are easy to get at and rinse. The Qrevo S5V washes its pads with whatever temperature water you fill it with, so there’s no hot-water wash, and the Saros needs its water station looked after too. The Q7 M5+ has no mopping dock, so you fill its small water tank and fit the pad by hand. The Saros dock has an automatic detergent dispenser and the MOVA comes with detergent, so floor cleaner is one more thing to buy again.
On Amazon, Roborock sells the Saros 10R, Qrevo S5V and Q7 M5+ in bundles with spare dust bags, and the Qrevo S5V with spare mop cloths, which is worth a look when you buy.

Still deciding whether you need a robot vacuum at all? Start with my guide to the best robot vacuums, and if mopping is the priority, see my robot vacuums that mop. If you have thick carpet, none of these is a specialist, so check my robot vacuums for thick carpet first, and if you’re hoping to retire the upright, read whether a robot vacuum can replace a normal vacuum. And once it’s quiet enough to live with, it will need a name, and here are some ideas for naming your robot vacuum.
What changed
- October 2026: replaced all nine old picks with five current robots ranked by TechGearLab’s measured decibels. The Proscenic M8 is no longer sold, and the other old picks were older models without measured figures.
- October 2026: removed the old decibel figures, which had no source, and added a plain-English decibel guide, a side-by-side noise table and a section on dock noise.
- October 2026: added privacy notes for each robot, an answer on the quietest Roomba, running costs and a “which one fits you” checklist.
FAQ
What is the quietest robot vacuum?
The quietest robot vacuum in TechGearLab’s measurements is the Roborock Saros 10R, at 50.0 dB while cleaning and 66.4 dB while its dock empties. That’s about as loud as a calm conversation. The MOVA P10 Pro Ultra, at 53.3 dB, is the quiet pick at a mid-range price.
Is there a silent robot vacuum cleaner?
No robot vacuum cleaner is silent, because the motor, brushes and wheels all make noise. The quietest measured robots run at about 50 to 55 dB, roughly a normal conversation, while most robot vacuums run between 50 and 65 dB.
What is the quietest Roomba?
There isn’t a clearly quieter Roomba. TechGearLab measured the Roomba Combo 10 Max at 58.1 dB, the i3+ EVO at 58.3 dB and the QO120 at 58 dB, all louder than the five robots on this list.
What is the quietest robot vacuum and mop?
The Roborock Saros 10R is the quietest robot vacuum and mop measured, at 50.0 dB while cleaning, and it washes its own mop pads. If you want to avoid dock noise entirely, the Narwal Freo X Ultra measured 53.8 dB and has no loud emptying cycle.
How many decibels is a quiet robot vacuum?
A quiet robot vacuum runs at about 55 dB or less while cleaning. Every 10 dB sounds roughly twice as loud, so a 50 dB robot sounds about half as loud as a 60 dB one. Check the dock too, because self-emptying docks often reach 70 to 80 dB.
Why is the robot vacuum dock louder than the robot?
A self-emptying robot vacuum dock pulls the dust out of the robot’s bin in one strong blast, so it’s louder than the robot cleaning. In TechGearLab’s tests the Roborock Q7 M5+ measured 55.7 dB while cleaning and 71.4 dB while its dock emptied. The blast is brief, and the Narwal Freo X Ultra avoids it by compressing dust inside the robot instead.
Can a quiet robot vacuum clean carpet well?
A quiet robot vacuum can clean carpet reasonably well, but none of these is a deep-carpet specialist. The Roborock Saros 10R picked up 82% of TechGearLab’s carpet test mess and the Roborock Q7 M5+ picked up 57%, so homes with thick carpet still need a regular vacuum now and then.
