The gap between the quietest and loudest vacuums is enormous. A 53 dB robot vacuum is barely noticeable in the next room. An 87 dB upright makes phone conversations impossible. Yet most shoppers don’t have a practical reference for what these numbers actually mean.
This database catalogues published decibel ratings for over 60 vacuum models, organised by type and ranked from quietest to loudest. Use it to find vacuums that fit your noise tolerance, whether you work from home, have sleeping babies, or simply hate how loud your current machine is.
For detailed reviews of specific quiet models, see our quiet vacuum cleaner reviews.
The Decibel Scale: A Practical Reference
The decibel (dB) scale is logarithmic, not linear. That means the difference between 60 dB and 70 dB isn’t “a little louder” - it’s roughly twice as loud to the human ear. Understanding this relationship matters for making informed comparisons.
Everyday Sound Reference Chart
| Decibel Level | Everyday Sound | How It Feels |
|---|---|---|
| 30 dB | Whisper, quiet library | Barely audible |
| 40 dB | Quiet residential area | Very quiet |
| 50 dB | Moderate rainfall | Comfortable background |
| 53 dB | Narwal Freo Z10 Ultra | Noticeable but unobtrusive |
| 55 dB | Eufy RoboVac 11S Max | Quiet conversation possible |
| 60 dB | Normal conversation | Standard indoor level |
| 63 dB | SEBO Airbelt D4 canister | Talk normally while vacuuming |
| 65 dB | Busy restaurant | Slightly raised voice needed |
| 66 dB | Miele C3 Calima (setting 3) | Talk normally while vacuuming |
| 68 dB | SEBO Felix upright | Raised voice needed |
| 70 dB | Shower running | Clearly loud |
| 75 dB | Busy traffic, dishwasher | Uncomfortable for some |
| 78 dB | Shark Navigator upright | Must shout to be heard |
| 80 dB | Alarm clock, blender | Unpleasant for extended use |
| 85 dB | Hearing damage threshold | NIOSH 8-hour exposure limit |
| 87 dB | Dyson V10 Animal (max) | Hearing protection recommended |
| 90 dB | Lawn mower, food processor | Painful for some |
Miele discontinued the Complete C3 series in 2026 and the Guard L1 replaces it. Miele publishes no noise figure for the Guard L1, so the C3 stays in this table as the reference point.
The 10 dB Rule
Every 10 dB increase doubles perceived loudness. This means:
- A vacuum at 75 dB sounds twice as loud as one at 65 dB
- A vacuum at 85 dB sounds four times as loud as one at 65 dB
- A vacuum at 65 dB sounds half as loud as one at 75 dB
This is why the gap between a 66 dB Miele canister and an 82 dB Dyson V15 on max power is so dramatic. The Dyson sounds roughly three times louder despite being an excellent vacuum.
Robot Vacuum Noise Database
Robot vacuums are the quietest category overall, making them ideal for homes where noise is a primary concern. Their smaller motors don’t produce as much raw suction, but they compensate with daily automated cleaning.
| Model | Noise Level | Suction | Navigation | Rank |
|---|---|---|---|---|
| Narwal Freo Z10 Ultra | 53 dB | 18,000 Pa | 3D ToF + Dual LiDAR + RGB Cameras | Quietest |
| Eufy RoboVac 11S Max | 55 dB | 2,000 Pa | BoostIQ | |
| Eufy RoboVac G30 Edge | 55 dB | 2,000 Pa | Smart Dynamic | |
| Eufy RoboVac X8 Hybrid | 56 dB | 2x 2,000 Pa | iPath | |
| Dreame L20 Ultra | 63 dB | 7,000 Pa | LiDAR | |
| iRobot Roomba 694 | 65 dB | Standard | iAdapt | |
| iLife V9e | 65 dB | 3,000 Pa | Gyroscope | |
| Shark IQ Robot AV2501AE | 65 dB | 1,000 Pa | IQ Nav | |
| Shark Matrix Robot | 65 dB | Enhanced | 360 LiDAR | |
| Shark Matrix Plus 2-in-1 | 65 dB | Enhanced | 360 LiDAR | |
| Shark AI Ultra Robot | 65 dB | Not specified | AI Laser | |
| Shark AI Ultra 2-in-1 | 65 dB | Not specified | AI Laser | |
| Ecovacs Deebot X2 Omni | 67 dB | 8,000 Pa | LiDAR + Camera | |
| Ecovacs Deebot T20 Omni | 67 dB | 6,000 Pa | TrueDetect 3D | |
| Ecovacs Deebot N10 Max | 67 dB | 4,300 Pa | TrueMapping | |
| Roborock S8 MaxV Ultra | 67 dB | 10,000 Pa | LiDAR + Camera | |
| Roborock S8 Pro Ultra | 67 dB | 6,000 Pa | LiDAR + Camera | |
| Roborock Q-Revo | 67 dB | 5,500 Pa | LiDAR | |
| Roborock Q7 Max | 67 dB | 4,200 Pa | LiDAR | |
| Roborock Q5 | 67 dB | 2,700 Pa | LiDAR | |
| iRobot Roomba J7 | 68 dB | Standard | PrecisionVision | |
| iRobot Roomba J9+ | 68 dB | Enhanced | PrecisionVision | |
| iRobot Roomba i7 | 68 dB | 10x Standard | vSLAM | |
| iRobot Roomba S9 | 70 dB | 40x Standard | vSLAM | |
| Eufy X8 Pro | ~70 dB | 2x 4,000 Pa | iPath | |
| Miele Scout RX3 | 72 dB | 30 W | Smart Nav | Loudest robot |
Key takeaway: The Narwal Freo Z10 Ultra at 53 dB is so quiet you may forget it is running, and it carries forward the noise floor set by its discontinued predecessor, the Freo X Ultra. Eufy’s lineup consistently delivers the best noise-to-value ratio for budget shoppers. Roborock and Ecovacs cluster around 67 dB, still quiet enough for daytime use without disturbance.

Canister Vacuum Noise Database
Canister vacuums generally run quieter than uprights because the motor housing is separated from the cleaning head, and premium brands like Miele and SEBO invest heavily in acoustic insulation.
| Model | Noise Level | Suction | Filtration | Rank |
|---|---|---|---|---|
| SEBO Airbelt D4 Premium | 63 dBA | Not specified | S-class | Quietest published spec |
| Miele Complete C3 Calima | 60 dB (setting 1) to 72 dB (setting 6) | Not published by Miele | HEPA AirClean | |
| Miele Complete C3 Soft Carpet | Not published by Miele | Not specified | HEPA AirClean | |
| Eureka Mighty Mite 3670G | ~70 dB | Not specified | Standard | Budget option |
| Miele Compact C1 Turbo Team | 71 dB | Not specified | AirClean | |
| Miele Classic C1 Pure Suction | 72 dB | Not specified | AirClean | |
| Miele Compact C1 Pure Suction | 72 dB | Not specified | AirClean | |
| Miele Classic C1 Cat & Dog | 72 dB | Not specified | AirClean |
Key takeaway: Miele and SEBO dominate the quiet canister segment. SEBO publishes 63 dBA for the Airbelt D4, which puts it about level with a normal conversation. Even Miele’s loudest canisters at 72 dB are quieter than most uprights on their lowest settings.
For a comparison of canister versus upright noise and performance trade-offs, see our canister vs upright vacuum guide.
Cordless Stick Vacuum Noise Database
Cordless vacuums have a wide noise range. On low power, many are acceptably quiet. On boost mode, models like the Dyson V10 Animal reach levels that warrant hearing protection.
| Model | Noise Level | Suction | Notes | Rank |
|---|---|---|---|---|
| Makita XLC07 (low mode) | 70 dB | Not specified | Low mode only | Quietest on low |
| Dyson V15 Detect | 73 dB | 240 AW | Eco mode | Eco mode quiet |
| MOOSOO K17 | 75 dB | 17,000 Pa | Single speed | |
| Shark WandVac WV201 | ~75 dB | Tapered nozzle | Handheld hybrid | |
| Roborock H60 Ultra | 75 dB(A) | 210 AW | A-weighted | |
| Milwaukee M18 Fuel | 75 dB | 20 CFM | Tool-only | |
| Miele Triflex HX2 Pro | 77 dB | 150 AW | PowerUnit on top | |
| Dyson V15 Detect (boost) | 82 dB | 240 AW | Max power mode | |
| Makita XLC07 (high mode) | 82 dB | Not specified | High mode | |
| Samsung Bespoke Jet | ~84 dB | 210 AW | Max power | |
| LG CordZero A9 Ultimate | 84 dB | 265 AW | Max power | |
| Dyson V10 Animal | 87 dB | 150 AW | Loudest cordless | Loudest |
Key takeaway: Most cordless vacuums are marketed with maximum suction figures but rated for noise at maximum power. In everyday use on lower settings, models like the Dyson V15 are far quieter than the spec sheet suggests. Miele’s Triflex HX2 Pro sits mid-table at 77 dB, so buy it for the filtration and the three-configuration body rather than for quietness; on noise alone the V15 in eco mode is the better cordless here.
For more on the cordless vs corded debate, including noise considerations, see our cordless vs corded vacuum comparison.
Upright Vacuum Noise Database
Uprights are generally the loudest portable vacuum category due to their powerful motors and direct-drive brush systems.
| Model | Noise Level | Type | Notes | Rank |
|---|---|---|---|---|
| SEBO Felix Premium | 68 dB | Residential | Quietest upright | Quietest |
| Hoover HushTone | 69 dB | Commercial | Designed for offices | |
| SEBO Automatic X5 | 69 dB | Residential | Auto height adjust | |
| Shark Apex DuoClean AZ1002 | ~75 dB | Residential | Lift-Away | |
| Shark Stratos Upright | ~75 dB | Residential | CleanSense IQ | |
| Miele Dynamic U1 Cat & Dog | ~78 dB | Residential | Sealed system | |
| Miele Dynamic U1 Upright | ~78 dB | Residential | Sealed system | |
| Shark Navigator Lift-Away | 78-82 dB | Residential | Multiple models | |
| Shark Navigator Pro NV356E | 78-82 dB | Residential | Wide range | |
| Milwaukee M18 Compact | 78 dB | Tool/Commercial | Battery-powered | |
| Sanitaire SC679J | 78 dB | Commercial | Heavy-duty | |
| Shark Vertex DuoClean | 80 dB | Residential | PowerFins | |
| Oreck Commercial XL2100RHS | ~80 dB | Commercial | Lightweight design | Loudest |
Key takeaway: SEBO uprights are the clear noise winners at 68-69 dB, a full 10+ dB quieter than most Shark Navigators (which means they sound roughly half as loud). The Hoover HushTone was specifically engineered for noise-sensitive commercial environments and lives up to its name.
Specialty Vacuum Noise Reference
| Model | Noise Level | Type | Notes |
|---|---|---|---|
| NuTone PurePower PP500 | 62 dB | Central vacuum | Motor in utility room |
| CanAvac LS-590 | 65 dB | Central vacuum | Motor in utility room |
| ProTeam Super CoachVac | 63 dBA | Backpack | A-weighted rating |
| Shark UltraCyclone Pet Pro | ~78 dB | Handheld | Corded handheld |
| Shop-Vac 5989300 5-Gallon | 78-80 dB | Wet/dry | Standard shop vac |
| VacMaster Beast VFB511B | 78 dB | Wet/dry | Compact shop vac |
| DeWalt DXV10P 10-Gallon | 78-80 dB | Wet/dry | Heavy-duty |
| Rainbow SRX | 70-75 dB | Water filtration | Unique technology |
Central vacuum systems deserve a special mention. The 62-65 dB rating is measured at the motor unit, typically installed in a garage or basement. At the cleaning head (where you actually stand), you only hear airflow through the hose, which is significantly quieter. This makes central vacuums the best option for noise-sensitive households with the budget for installation.
What Makes Some Vacuums Quieter Than Others?
Noise is an engineering problem with known solutions. The quietest vacuums invest in all of these areas:
Motor Technology
Brushless digital motors are inherently quieter than brush motors because they eliminate the physical contact between brushes and commutator that generates friction noise. Dyson’s Hyperdymium motor, Miele’s Vortex motor, and Roborock’s brushless motors all fall in this category.
Motor speed matters too. Lower RPM motors running at higher torque produce less noise than high RPM ones. Some vacuums use intelligent speed control (like Dyson’s Auto mode and Shark’s CleanSense IQ) that runs the motor only as fast as the current floor type demands.
Sound Insulation
Premium vacuums use multi-layer insulation around the motor housing. Miele’s own US spec sheets list a Silence System on the Complete C3 canisters, though they don’t publish what it’s built from. Budget vacuums may use a single thin plastic housing with no dedicated insulation.
Bagged vs bagless: The vacuum bag itself acts as sound insulation, which is one reason bagged Miele canisters are consistently quieter than bagless designs of comparable power. See our bagged vs bagless comparison for the full trade-off analysis.
Airflow Path Design
Turbulent airflow generates noise. Well-designed vacuums use smooth, gradually expanding airflow channels that minimise turbulence. Poorly designed ones have sharp bends, sudden diameter changes, and rough interior surfaces that create whistling and roaring sounds.
Vibration Dampening
Motor vibration transmits through the vacuum body and amplifies noise. Premium models mount motors on rubber isolators and use precision-balanced rotating components to minimize vibration at the source.
Noise Reduction Tips for Your Current Vacuum
If buying a new vacuum isn’t in the budget, these steps will take some of the noise out of your existing machine:
Maintenance-Based Noise Reduction
- Replace or wash filters. Clogged filters force the motor to work harder, increasing both RPM and noise
- Clear brush roll of hair wraps. Tangled hair creates vibration and grinding sounds
- Check for loose connections. Rattling hoses, loose latches, and worn gaskets amplify noise
- Empty the bag/bin at half capacity. Overfull containers restrict airflow, forcing the motor to compensate with more RPM
- Use lower power settings. Most cleaning tasks don’t require maximum suction, and dropping a power level makes a real difference. Top-Aspirateur’s decibel-meter testing of the Miele Complete C3 measured roughly 2 to 3 dB per step down its six settings, 72 dB at the top and 60 dB at the bottom
For comprehensive vacuum care instructions, see our vacuum maintenance guide.
Environment-Based Noise Reduction
- Close doors between rooms. A wall and a closed door take a lot of the noise out for anyone in the next room
- Vacuum on carpet before hard floors. Carpet absorbs sound; hard surfaces reflect it
- Use robot vacuums for daily maintenance. Schedule them during work or school hours, then deep clean with a traditional vacuum weekly
- Add rubber pads to the vacuum’s base if it vibrates on hard floors
EU Noise Rules, and Why They Don’t Compare to the Tables Above
The EU caps vacuum cleaner noise through its ecodesign rules. Regulation 666/2013 states that from 1 September 2017, a vacuum cleaner’s “sound power level shall be less than or equal to 80 dB(A)”.
That 80 dB is a sound power level, not the sound pressure your ears pick up standing over the machine, so it can’t be read against the figures in the tables above. Sound power describes the total acoustic energy a machine puts out; sound pressure is what a meter reads at a set distance, and it lands well below the sound power figure for the same appliance. An EU vacuum at 80 dB(A) sound power isn’t quieter than a US machine measured at 78 dB at the handle. The two numbers measure different things, and manufacturers rarely spell out which one they’re quoting.
The energy label that once carried a noise figure is gone. In 2018 the EU General Court annulled the vacuum cleaner energy labelling regulation, and the Commission now states that “energy labelling rules for VCs set in Commission Delegated Regulation (EU) 665/2013 have been annulled and these products no longer have an energy label”. The 666/2013 ecodesign cap still applies.
The US has no equivalent federal noise limit for household vacuums.

Methodology
These figures come from a mix of sources, and that matters more than the numbers suggest. Where a manufacturer publishes a decibel rating, that’s what you see here. Where one doesn’t, and several don’t, including Dyson, the figure comes from independent decibel-meter measurement instead. Rows marked with a tilde are approximate.
Nobody is measuring these the same way. Manufacturers who cite a standard usually cite IEC 60704-2-1, but they differ on microphone distance and on which power setting they quote, and A-weighted figures (dBA) discount low-frequency rumble against unweighted ones. Where the weighting is stated we’ve noted it. So treat a two or three decibel gap between two models as noise in the data rather than a difference you’d hear, and treat the ten-plus decibel gaps as real.
Actual noise levels in your home will vary with floor type (hard floors reflect sound, carpet absorbs it), room size, ceiling height, and which attachment is fitted. Turbo brush attachments are louder than standard floor tools.
We update this database regularly as new products are added to our review library. For suction power data to pair with these noise figures, see our vacuum suction power chart.

Frequently Asked Questions
- What is a good decibel level for a vacuum cleaner?
- Below 70 dB is considered quiet for a vacuum cleaner; you can hold a conversation while vacuuming. Between 70-78 dB is average and comfortable for most people. Above 80 dB is loud and may require hearing protection during extended use. The quietest full-size vacuums operate at 63-66 dB, while ultra-quiet robot vacuums can run at 53-55 dB.
- How loud is 70 dB compared to normal conversation?
- Normal conversation is about 60 dB, so 70 dB is noticeably louder but not dramatically so. You would need to raise your voice slightly to be heard over a 70 dB vacuum. At 80 dB, you would need to shout. The key is that every 10 dB increase sounds roughly twice as loud to the human ear, so a 70 dB vacuum sounds about twice as loud as a 60 dB conversation, and an 80 dB vacuum sounds four times as loud.
- Are robot vacuums quieter than regular vacuums?
- Yes, significantly. Most robot vacuums operate between 53-70 dB, while upright vacuums typically run at 75-87 dB. The trade-off is cleaning power; robot vacuums achieve their quiet operation partly because they have smaller, less powerful motors. However, robot vacuums compensate by making multiple passes and running daily. For a complete analysis, see our robot vacuum vs regular vacuum comparison.
- Can vacuum noise cause hearing damage?
- Prolonged exposure to sounds above 85 dB can cause gradual hearing damage. Some vacuums, particularly older uprights and the Dyson V10 Animal at 87 dB, operate in this range. While typical vacuuming sessions of 15-30 minutes are unlikely to cause permanent damage, professionals who vacuum for hours daily should wear hearing protection with any vacuum above 80 dB. The National Institute for Occupational Safety and Health (NIOSH) recommends limiting 85 dB exposure to 8 hours per day.
- Do quieter vacuums have less suction?
- Not necessarily. Noise reduction comes from better engineering, not reduced power. An independent decibel-meter test of the Miele Complete C3 measured 60 dB on suction setting 1 and 72 dB flat out on setting 6, while plenty of budget uprights sit at 80 dB and above. Premium brands achieve quietness through brushless motors, multi-layer insulation and smoother airflow paths. Within a single product line, though, higher power settings are always louder than lower ones.
- Why are Miele vacuums so much quieter than other brands?
- Miele lists a Silence System on its own canister spec sheets, and the sealed bag adds a layer of sound dampening that bagless designs lack. Miele doesn't publish the construction behind it, so treat any layer-by-layer description you read as guesswork. Miele isn't always the quietest, either: SEBO edges it in both the canister and the upright tables below.
