A robot that vacuums and mops is two machines in one shell, and the noise figures makers print for it usually describe only the quieter half. Search for the quietest robot vacuum mop combo and you will find numbers in the low 50s. Almost all of them are for mopping with the vacuum fan turned down or switched off.
This guide reads the mopping figures for what they are. We took the Roborock and ECOVACS models from our quietest robot vacuums guide and our two brand pages, added two Narwal robots whose images carry mopping figures, re-opened each product page and spec table, confirmed every figure printed inside an image by looking at the image, and checked Dreame, eufy, Narwal, SwitchBot, Shark, iRobot and Samsung for mopping figures of their own. We rank only figures that share a label and a unit, and keep the dock's washing, drying and emptying apart from the robot.
Our picks are listed above, with full specifications for each.
Roborock's manuals say plainly what its mopping figures measure. The Q10 manual says that in Mop Only "The main brush and fan reduce their operating speed, and the mopping module lowers itself", and adds "Compared with other cleaning modes, noise emanating from Mop Only is much lower." The S8 Max Ultra manual goes further: "the main brushes and fan stop operating", and the same note follows.
So a Roborock mop-only figure is close to the floor of what the robot can sound like. It is a fair figure for mopping a kitchen after dinner. It is no guide to vacuuming a rug, which Roborock covers with a separate figure on very few models: the QV 35A at 64dB in Balanced Mode, and the Q7 M5 and Q7 M5+ at 65dB (Balanced).
ECOVACS measures the other thing. Its spec tables have a row called "noise-standard mode-sweep&mop (dBA)": the robot vacuuming and mopping at the same time, at the standard suction level. That figure includes the fan, which is why ECOVACS's numbers start at 60 dBA while Roborock's mopping numbers start at 53dB. The gap tells you about the test, not about which robot is quieter.
The groups, and why they do not line up
We sorted every current figure by the maker's own label and unit. We rank inside a group and never across groups.
Roborock, Mop-only Mode (dB)
- Qrevo 2 Pro: under 54dB, printed with a less-than sign.
- Qrevo S Pro: 55dB on a page chart marked "Mop-only mode".
Roborock, Mop Only, a single figure (dB)
- QV 35A: 55dB in Mop Only Mode, at moderate scrub intensity.
- Q7 M5 and Q7 M5+: 60dB (Mop Only).
ECOVACS, standard mode, sweep and mop (dBA), quietest first
- X9S PRO OMNI: 60.
- X11 OmniCyclone: 62.9.
- T50 OMNI, T50 PRO OMNI and T80S OMNI: 63.
- X12 OmniCyclone and X12 PRO OMNI: 64.4.
- T50 MAX PRO OMNI: 64.6.
- T80 OMNI: 65.
- N30 PRO OMNI: 65.3.
- X9 PRO OMNI: 65.7.
Narwal, Mopping-only mode (dB(A))
- Freo S: under 60dB(A), from lab tests. Its Sweeping-only mode figure is under 62dB(A).
Labels of their own, each in a group of one
- Roborock Qrevo CurvX: 53dB in Standard Mop-only Mode, in a semi-anechoic chamber.
- Roborock Saros 10R: 55dB or less in Quiet mop-only mode, in a semi-anechoic chamber.
- Roborock Qrevo Curv 2 Flow: 62 to 65 dB in Vac & Mop mode.
- Narwal Flow: 60dB or less in Vacuum and Mop.
Three things keep the groups apart. The units differ: Roborock's figures and the Narwal Flow's are plain dB, while ECOVACS's dBA and the Freo S's dB(A) are A-weighted, which our explainer on dBA covers. The modes differ: one has the fan slowed and the other has it running. And no maker states a measuring distance. Our page on why decibel ratings rarely compare across brands explains why that matters.
Within a group, small gaps are small. Roughly every 10 dB sounds about twice as loud, so the 5 dB between the QV 35A and the Q7 M5+ in Mop Only is a difference you might hear. The 1 dB between the Qrevo 2 Pro's ceiling and the Qrevo S Pro's chart, or the 0.1 dBA between some DEEBOTs, is not.
Mop type: spinning pads, rollers and vibrating plates
The makers publish no noise figure that separates one kind of mop from another, so we cannot tell you which is quieter. What they do publish is how each one works.
Spinning pads. Two round pads turn against the floor. Roborock says the Qrevo 2 Pro, QV 35A and Qrevo S Pro spin theirs at up to 200 RPM, and the Qrevo CurvX presses down with up to 12N. ECOVACS's T50 OMNI uses "Rotating Dual-Mop" plates. Pads are easy to lift or leave in the dock, which helps on rugs.
Rollers. A long cylinder rolls and is washed as it turns. ECOVACS uses them on the X9S PRO OMNI, X11, X12 and T80 lines, and says the T80S roller "scrubs 220 times per minute" at 3,800Pa of pressure. Roborock's Curv 2 Flow uses one too.
Track mops. Narwal's Flow uses a FlowWash track mop, which Narwal says cleans itself in real time with 113°F warm water as it turns at 110 RPM.
Vibrating plates. A flat mop cloth on a plate that vibrates. Roborock's S8 Max Ultra and Q10 manuals both label part of the VibraRise mop module as a "Vibration Module", and say the module lowers itself in Mop Only. Neither robot carries a current mopping figure, so neither is ranked here.
Carpets: how high the mop lifts
A wet mop dragged over a rug is the main reason people turn mopping off, and the makers handle it in three ways.
Lifting the mop. ECOVACS lists "automatic mop lifting (mm)" in its tables: 9 on the T50 OMNI, 10 on the X11 and T80 OMNI, and 15 on the X9S PRO OMNI and X12. Roborock says the Qrevo 2 Pro's "mopping modules can be lifted up to 15 mm", the Qrevo S Pro's up to 10 mm, the QV 35A's 10 mm, and the Curv 2 Flow's roller by up to 15 mm. Narwal lists "12 mm Mop Lifting" for the Flow. On the Qrevo CurvX, "Mops and chassis lift together up to 17 mm" on higher-pile carpet. The Saros 10R page gives two figures: "Mops Lifted 17mm" in its text and "22mm Maximum Mop Lifting" in its images.
Leaving the mop behind. The Qrevo 2 Pro and Saros 10R can return to the dock and leave their mops there before vacuuming a rug, which Roborock calls ideal for long-pile carpets.
Covering it. The Curv 2 Flow drops a water-blocking guard under its lifted roller, and the X12 deploys a cover as the roller lifts 0.59 in.
Lifting does not make the robot quieter. Carpet usually means more suction: ECOVACS lists "Carpet pressurization" as a feature on most DEEBOTs, and Roborock's Carpet Boost raises suction on rugs. Neither maker prints a figure for it.
The dock washes and dries, and that is noise too
A mopping robot's dock does more than a vacuum's. It empties the bin, and it also washes the mops between rooms and dries them after the clean. Those are separate sounds, and we keep them out of the robot rankings.
Drying. Roborock gives 45 dB for "Low Drying Noise" on the Qrevo 2 Pro and Qrevo S Pro, "as low as 45 dB in a semi-anechoic chamber"; a chart on the S Pro page plots it at 48dB. The Curv 2 Flow's FAQ gives about 56 to 57 dB for washing and drying. ECOVACS prints no drying figure. Drying runs for 2, 3 or 4 hours on most of these docks, so it is often the sound you hear longest.
Washing. Narwal gives 60dB or less for the Flow dock's "Antibacterial Washing". ECOVACS prints a "Noise of mop washing (dBA)" row: 48.3 water outlet and 57.8 pumping on the X12 OmniCyclone, 54.9 and 61.5 on the X11, then 60 on the X9S PRO OMNI, 63 on the T50 OMNI and 65 on the T80S OMNI.
Emptying. The loudest of the three wherever it is published: 70 dB on the Curv 2 Flow by Roborock's FAQ, and from 70 to 83 dBA across ECOVACS's current docks. Our Roborock and ECOVACS brand pages list every dock figure each maker prints.
Hot water. Makers quote the wash temperature in different ways. Roborock gives 149°F on the Qrevo 2 Pro and 167°F on the Qrevo S Pro and Curv 2 Flow, and footnotes each as the temperature "at the internal heater output, not the temperature of the mop itself". For the Qrevo CurvX it gives 176°F, footnoted as the water at the dock's clean water dispensers, and the Saros 10R page also says 176°F hot water mop washing. ECOVACS gives "Y，75℃" in the X11 table and 70°C in the T50 OMNI page text. No maker ties a noise figure to the heater.
When and where to mop quietly
The figures point to a simple routine. Vacuum while the house is empty, at whatever suction your floors need. Mop later, in mop-only mode where the robot has one, because that is when the low figures apply. A mopping robot spends most of its time on hard floors, which reflect sound more than carpet, so expect it to sound louder in a tiled kitchen than the figure suggests. Our page on a quiet open-plan kitchen covers how hard surfaces carry sound.
Then set the dock. Roborock's manuals set a default Do Not Disturb window of 22:00 to 08:00, and on the Qrevo CurvX and Qrevo S Pro let you choose whether emptying and drying run inside it. ECOVACS's manuals say the dock will not empty in Do Not Disturb mode. In a flat, where the dock may share a wall with a neighbor, our apartment robot vacuum guide goes through those settings. With a shedding pet, mopping does little for fur, and our pet robot vacuum guide covers the suction modes that do.
What the other makers publish
Dreame. The L20 Ultra spec table lists "Lowest Noise 63dB(A)*", footnoted "The lowest noise was measured in the mopping mode." It was sold out on Dreame's US store when we checked, so it is not ranked. An image on the X60 Max Ultra Complete page about hot mopping prints "55dB(A) Ultra-Quiet", footnoted only as in-house lab data under specific testing conditions, with no mode named. Dreame's D30 Ultra CE page says drying noise is cut to 37 dB, a dock figure. We found no other mopping figure in the text or images of the Dreame pages we read.
eufy. The comparison table on eufy's Omni C20 page gives "Noise (Standard, Vacuum-only)" for three robots, from 54 to 54.89 dB. Those are vacuum figures, not mopping ones.
Narwal. Two Narwal robots do publish mopping figures, and both are above: the Freo S in Mopping-only mode and the Flow in Vacuum and Mop. The rest do not name a mopping mode. The Freo 20 says "As low as 56.9 dB in Quiet Mode", and an image on its page footnotes that as "56.9 dB(A) measured during quiet mode vacuuming". The Flow 2 says it operates under 56.5 dB, the Freo X10 Pro's silent cleaning mode operates below 59dB, and the Freo 20 Edge page says both 56 dB and 59 dB.
SwitchBot. The K10+ Pro page says 45dB without a mode, and the K20+ Pro spec table says "Noise Level ≤ 80dB". The S10 and S20, its mopping robots, gave no figure in their page text or images.
Shark, iRobot and Samsung. We found no figure in the page text we could load for Shark's PowerDetect 2-in-1 robots or iRobot's Roomba Combo. Both sites build much of the page in the browser, so we could not read every image there. Samsung's Bespoke AI Jetbot Combo page did not load its spec table for us.
The trade-offs
Quiet mopping is not quiet cleaning. The low figures cover the mop with the fan slowed. Vacuuming is louder, and only a few of these robots carry a figure for it.
Hot water costs power, and the dock runs longer. Washing and drying add hours of dock activity after every clean.
A base that only empties is quieter after the clean, and more work. The Freo S base does not wash or dry the mop, so there is no drying noise, but you wash the pad yourself.
Quiet mode runs longer. ECOVACS lists the T50 OMNI at 255 minutes sweeping a hard floor in silent mode, against 175 minutes sweeping and mopping in standard.
How we chose
We started from the Roborock and ECOVACS robots in our existing guides, re-opened every product page and spec table, and read the text inside the Roborock pages' images, checking each figure by viewing the image itself. We read the Roborock manuals that explain Mop Only, and checked Dreame, eufy, Narwal, SwitchBot, Shark, iRobot and Samsung for mopping figures, reading the images on the Narwal, SwitchBot and main Dreame pages as well as the text. We grouped each figure by the maker's mode label and unit, ranked only within a group, and kept dock figures apart. Prices are the makers' US list prices on October 5, 2026; many models were on sale below list.
We did not measure any of these robots. Every figure here is the maker's own, none states a measuring distance, and only Roborock names a test room for some of them. Your floors, rugs and walls will change what you hear, and a mopping figure says nothing about the same robot vacuuming at full power.
