Search for Roborock robot vacuum decibels and the spec tables come up empty. Roborock lists dimensions, weight and battery size there, and its user manuals carry no noise figure at all. The numbers exist, but most of them sit inside the product page images, in large type with a footnote underneath.
We opened the product page for every robot in Roborock's US robot vacuum collection, and the user manual where Roborock links one. Nine current robots carry a published noise figure for the robot, and five carry one for the dock. This page lists every one, says which mode or dock action Roborock ties it to, and ranks each figure only against others with the same label and unit.
Our picks are listed above, with full specifications for each.
Almost every Roborock figure is in plain dB. Two dock figures are the exceptions: 45dB(A) for drying on the Qrevo S5V, and more than 82 dBA beside the Q7 M5+ dust bag. Roborock never states a measuring distance. Four product pages add a footnote naming the room: the noise level is "as low as" a figure "in a semi-anechoic chamber", a test room with sound-absorbing walls. That makes the number cleaner and lower than you will hear at home, where floors and walls reflect sound.
The labels matter more than the numbers. Roborock's app offers suction levels called Quiet, Balanced, Turbo, Max and Max+, and modes for vacuuming, mopping or both. Its published figures touch only a few of those:
- Mop-only mode. Most figures describe this. The Q10 manual says that in Mop Only "The main brush and fan reduce their operating speed, and the mopping module lowers itself", and the S8 Max Ultra manual says the main brushes and fan stop operating. Both say "noise emanating from Mop Only is much lower." So a mop-only figure is close to the quietest the robot can be.
- Balanced. A real suction level, used for everyday vacuuming. Three current models give a figure for it: the QV 35A, Q7 M5 and Q7 M5+.
- Vac & Mop mode. The Qrevo Curv 2 Flow's figure, vacuuming and mopping at once, with no suction level named.
- Nothing for Turbo, Max or Max+. Roborock publishes no figure for its loudest settings on any current model.
Even within mop-only, Roborock uses four labels: "Standard Mop-only Mode", "quiet mop-only mode", "Mop-only Mode" printed as a ceiling with a less-than sign, and "Mop Only" printed as a single figure. We treat each as its own group.
Balanced, quietest first
- QV 35A: 64dB in Balanced Mode; 8,000 Pa.
- Q7 M5 and Q7 M5+: 65dB (Balanced); 10,000 Pa.
Mop Only, as a single figure, quietest first
- QV 35A: 55dB in Mop Only Mode. Its footnote says the data are based on suction at balanced mode and scrub intensity set to moderate.
- Q7 M5 and Q7 M5+: 60dB (Mop Only).
Mop-only Mode, printed as a ceiling, lowest first
- Qrevo 2 Pro: under 54dB; 20,000 Pa.
- Qrevo S Pro: under 55dB, and plotted at 55dB on a chart on the same page; 18,500 Pa.
Other labels, each in a group of one
- Qrevo CurvX: 53dB in Standard Mop-only Mode, in a semi-anechoic chamber; 22,000 Pa.
- Saros 10R: 55dB or less, printed with a less-than-or-equal sign, in "Quiet mop-only mode", in a semi-anechoic chamber; 22,000 Pa.
- Saros Z70: "55dB Quiet Cleaning", in an image about hot water mopping, with no mode named; 22,000 Pa.
- Qrevo Curv 2 Flow: 62 to 65 dB in Vac & Mop mode; 20,000 Pa.
Two of these figures were missing from our own earlier notes. Our quietest robot vacuums guide first listed the Q7 M5 and the Saros 10R as having no Roborock figure, because neither the page text nor the manual has one. Both pages do carry one, inside an image, which we found only on this closer read, and that guide now gives them.
Eight current robots have no figure anywhere we could read: the Q7 L5, Q10 S5+, Q10 X5+, Qrevo S5V, Qrevo Edge 2, Qrevo Edge 3 Pro, S8 Max Ultra and Saros 20. The Qrevo S5V does publish a dock drying figure, listed below.
The dock is the loud part
Roborock is more open about its docks than most makers. Five current models carry a dock figure, for one of two actions.
Emptying the dust bin. The Qrevo Curv 2 Flow FAQ says "When emptying the dust tank, the noise temporarily increases to 70 dB, similar to that of a high-power vacuum cleaner, but it lasts less than a minute." The Q7 M5+ page prints more than 82 dBA under "2.7L Dust Bag" without saying what it measures; next to the bag it most likely describes emptying. These are in different units, and one is a floor rather than a figure, so we do not rank them.
Washing and drying the mops. The Qrevo 2 Pro and Qrevo S Pro pages give "45 dB" for "Low Drying Noise", and say "the noise level when drying is as low as 45 dB in a semi-anechoic chamber". A chart on the Qrevo S Pro page plots "Low Drying Noise" at 48dB instead. The Qrevo S5V gives "45dB(A)" for "Low drying noise". The Qrevo Curv 2 Flow FAQ says washing and drying is "approximately" 56 to 57 dB, and another answer on the same page says it "performs low-noise hot air drying at 56 dB". Drying can run for hours after a clean, so a low figure here matters more than its size suggests.
Set beside the robots, the emptying figures stand out. On the Curv 2 Flow, emptying at 70 dB is 5 to 8 dB above the robot's own 62 to 65 dB. Our decibel chart puts those numbers next to everyday sounds.
What the gaps mean
Decibels are logarithmic. Roughly every 10 dB sounds about twice as loud. The 10 dB between the Q7 M5's 60dB in Mop Only and a dock emptying at 70 dB is a doubling. The 1 dB between the QV 35A and Q7 M5 in Balanced is too small for most people to hear, and with no distance stated it may be no gap at all. Treat a gap of 1 or 2 dB as a tie, and a gap of 5 or more as a real difference.
Roborock's quiet features, by their real names
Do Not Disturb (DND). Every manual we read sets "The default Do Not Disturb (DND) period" at "22:00 to 08:00". The Q7 M5+ manual says "In DND mode, the robot will not play voice messages", and the robot "will not auto-empty after returning to the dock in DND mode." The Qrevo CurvX and Qrevo S Pro manuals add that you can set "whether to enable auto top-up, emptying and drying, to dim indicator lights, or lower the volume of the voice message during the DND period." Our apartment robot vacuum guide explains how to set this up so the dock waits for morning.
SmartPlan. Roborock's automatic cleaning mode. On the Qrevo CurvX and Saros 10R pages it "Lowers power and reduces noise during Do-Not-Disturb periods", and on the Qrevo Edge 2 it is listed as "Low-Power Quiet for Do-Not-Disturb". Roborock does not say how much quieter.
Mop Only. Started from the app, with the fan slowed or stopped. It is the mode behind most of Roborock's figures, and the quietest way to run any of these robots.
Clean Along Floor Directions. On the QV 35A, Qrevo S5V and Q10 S5+, Roborock says the robot cleans along the direction of floor tiles, "reducing the noise from the main brush rubbing against floor cracks" (the QV 35A wording). There is no figure for it.
Quiet suction. The app's lowest suction level. Roborock prints no figure for it on any current model, though a Q10 S5+ image gives 150 minutes as its "Maximum Runtime in Quiet Mode".
Keeping a Roborock quiet
Roborock's manuals list the same causes of extra noise across models. For "Noise during cleaning", they say "The main brushes, side brush, or main wheels may be jammed. Turn off the robot and clean them." For "unusual noise when emptying", they point to a main brush or brush cover not installed properly, and to a blocked filter, air duct, suction inlet or dust bag. Pet hair makes both more likely, and our pet robot vacuum guide covers the trade between quiet modes and the suction a shedder needs.
How Roborock compares
This page ranks Roborock models only against each other. For how they sit among other brands, on each maker's own published figures, see our guide to the quietest robot vacuums linked above. Because Roborock, like most makers, states no measuring distance, read our explainer on why decibel ratings rarely compare across brands before treating a gap of a decibel or two as real. And since Roborock mixes dB, dB(A) and dBA on its docks, dBA explained sets out what the A means.
Models we did not rank
Roborock's US site still has pages for some older robots that are sold out there and missing from its robot vacuum collection, so we have not ranked them. The Saros 10 page says it is "the quietest Roborock ever" and footnotes "The sound level in Quiet Mopping is tested as low as 52 dB(A)" and dock self-emptying "as low as 72 dB(A)". The Qrevo Edge and Qrevo Curv S5X pages give 55dB in quiet mop-only mode. If you find one of these still on sale elsewhere, those are Roborock's figures for it.
How we chose
We read every robot in Roborock's US robot vacuum collection, opened each product page in full, including the text inside its images, and read the user manuals Roborock links from those pages. We recorded each noise figure in Roborock's words, with the mode, suction level or dock action it is tied to, and its footnote. We grouped figures by that label and unit, and ranked only within a group. Prices are Roborock's US list prices on October 5, 2026; most models were on sale below list.
We did not measure any of these robots. Every figure here is Roborock's own, from its product pages, and Roborock states no measuring distance for any of them. Your floors, rugs and walls will change what you hear, and nothing here covers the Turbo and Max settings that are the loudest a Roborock gets.
