How many decibels is a vacuum cleaner?
From 58 dBA to 88 dBA in the published figures. Sort them and SEBO sits at the top and Dyson at the bottom; read what each figure describes and the ranking stops meaning much.
| Maker | What its figure describes |
|---|
| SEBO | A setting only once: the BALANCE A1 figure is "only 69 dB on Power Level 1", its lowest of three. Its corded figures, from 58 dBA up, name no setting. |
| Dyson | Its loudest. Every Dyson figure here is Boost or handheld max mode, and the V15 sheet splits it by floor: 82 dBA on carpet, 87 dBA on hardwood. |
| Miele | No mode. Its data sheets carry a single "Volume in dB" line with no suction level, distance or standard. |
| Tineco | "As low as", a floor rather than a measurement. |
None of the four names a test standard or a distance, which means a 58 from SEBO and an 82 from Dyson are not 24 decibels apart in any meaningful sense. Miele's figures with no mode named and Tineco's as-low-as floor are no easier to place against them, as our page on comparing decibel ratings explains.
Dyson deserves some credit. Quoting the loudest mode and splitting the figure by floor surface makes its machines look worse on a spec sheet while telling buyers more than anyone else does.
To see how 58 to 88 dBA spans everyday sounds, from conversation to a vacuum cleaner as the National Park Service rates one, see our decibel chart.
Every figure below 69 in this guide belongs to a bagged vacuum: SEBO's canisters at 58 to 63 dBA and its FELIX upright at 68.
The next figure up is the one exception, SEBO's bagless cordless BALANCE A1, at 69 dB on level one. Miele's range shows the same pattern inside one brand, with 75.0 dB for the bagged Guard L1 and 78.0 for the bagless Boost CX1. No maker explains why, and this is a pattern in the published data rather than a rule of physics. If quiet is your priority, though, the data points at a bagged canister.
Our guide to the quietest canister vacuums takes that further, keeping SEBO's and Miele's figures in separate lanes and covering the low setting you would actually use, cord reach, bags and warranty.
The low setting is not sold as the quiet one
It is tempting to assume the low setting is the quiet setting. Nobody who makes these machines says so.
Miele's instructions describe the trade-off differently: reducing suction power suits the flooring and "reduces the amount of effort required to maneuver the floorhead". Dyson describes Eco mode as being for longer run time, not lower noise. SEBO implies it by quoting its BALANCE A1 figure at Power Level 1, but never states it. Use the low setting for hard floors and rugs by all means; just do not expect a maker to back a claim about decibels.
One maker does put a figure on each mode, on a stick vacuum. Our guide to the quietest cordless stick vacuums found Roborock rating its H60 at 75 dB(A) or less in ECO and 81 or less in MAX, both sound power, and no other stick vacuum maker giving a figure for more than one mode.
Pet owners face the hard end of that table, because fur on a rug pulls a stick out of Eco and into its loudest mode; the pet hair section of our stick vacuum guide quotes each maker's figure at that power mode.
Does a full bag or a clogged hose make a vacuum louder?
None of the manuals says so. They do say blockages hurt the machine.
Miele tells owners not to use the vacuum with any opening blocked, and to keep it free of dust, lint and hair. Blocked bag pores reduce suction power, and the bag change indicator misleads in both directions: fine dust like sawdust, sand, plaster or flour blocks the pores early and triggers a full warning, while hair and carpet lint can fill a bag before the indicator reacts.
SEBO's BALANCE A1 shuts off automatically if the brush roller jams or a clog develops, to prevent overheating. The FELIX has a warning light for a brush set too high, worn bristles, or a blocked roller.
SEBO sells only through dealers and publishes no prices, Miele's prices are promotional, and some Tineco and Dyson models are gone or hard to find.
SEBO publishes no prices
Its US site lists no price and no stock for any model, because it sells through authorized dealers. Its figures are the lowest here, so finding a dealer is worth it, but you cannot compare prices from the sofa.
The $849.00 and $589.00 recorded here are sale prices on Miele's site, with the promotion ending in October.
Tineco's older quiet models are gone
The Tineco vacuums first found with a decibel figure are no longer on Tineco's own store. Of its current sticks, only the A30S ("Noise Level 67.1 dB") and the PURE ONE A50S ("Noise Level 70 dB") print one, in their spec tables with no mode named; our Tineco vacuum decibels page lists every current Tineco figure.
Two Dyson models are hard to find
The V11 and V10 configurations whose figures Dyson publishes no longer have live pages at the URLs we tried.
Five mistakes quiet vacuum shoppers make
The commonest is ranking the published numbers against each other, when they describe different modes and, in Dyson's case, a different floor. Close behind it is assuming a quiet mode exists, since only SEBO quotes a specific power level.
Many shoppers also expect every brand to publish something. Most do not. That includes some of the biggest names in the category.
Then there is the bag indicator, which Miele says can read full when it is not and stay quiet when the bag is stuffed. And people forget where they will have to buy: the quietest figures here come from a dealer-only brand.
