How many decibels is a Dyson vacuum?
Dyson vacuum decibels, where Dyson prints them, run from 82 to 87 dBA of sound power. Each line below keeps one kind of figure, and only the first line is ranked. Prices come from Dyson's US store or its for business pages in October 2026.
- Boost mode on carpet, sound power: V15 Detect Pro 82 dBA ($849.99 for business), Motorbar V11 82 dBA ($569.99 for business), Gen5detect 84 dBA from the Australian sheet ($719.99).
- Boost mode on hardwood, sound power: V15 Detect Pro 87 dBA, Motorbar V11 87 dBA.
- No mode named, sound power: Car+Boat "HP82 dBa" ($299.99).
- Handheld modes on older sheets: V11 with High Torque head 88 dBA in handheld Boost, Cyclone V10 87 dBA in handheld max mode.
What is the quietest Dyson vacuum?
The V15 Detect and Motorbar V11 tie as the quietest Dyson vacuums on paper, at 82 dBA in Boost on carpet. The Gen5detect follows at 84 dBA under the same wording. Nothing else Dyson sells can join that ranking.
The tie is genuine on Dyson's paperwork: the two sheets carry the exact same sound line, word for word, and both machines run a 545W motor at 125,000rpm. The V15 adds a piezo sensor that counts and sizes dust, with the tally shown on its LCD screen.
The Car+Boat's HP82 matches the lowest stick number, but Dyson names no mode for it, so calling it as quiet as the V15 would be a guess.
Dyson splits its V15 Detect and V11 figures by floor, both in Boost: 82 dBA for carpet, 87 dBA for hardwood. Dyson gives no reason for the gap, and the Gen5detect sheet names carpet alone.
For a flat with bare floors, 87 dBA is the figure that applies when Boost is on. That is five dBA above the carpet number for one machine, and a five dBA step is easy to hear.
The floor split also means the Gen5detect's 84 dBA should be set against the V15's 82, never its 87. Its sheet says "Digital Motorbar cleaner head on carpet", and Dyson printed no hardwood number for it.
How loud is the Dyson V15 Detect?
The Dyson V15 Detect lists Boost at 82 dBA for carpet and 87 dBA for hardwood floor, as sound power, on its US Professional edition sheet dated 6.15.2023. No other V15 document we found prints a number.
That sheet is for the Pro kit, $849.99, which adds a second battery and a spare filter. Dyson's consumer store sells the V15 Detect Absolute with a car cleaning kit for $599.99, and its page has no sound row.
Dyson's V15 user manual describes three power modes: Eco for "Maximum run time", Auto or Med, where "Suction power automatically adapts to dust levels", and Boost. The 82 and 87 dBA describe Boost only, so a V15 left in Auto spends much of its time below the mode Dyson rated, without a published figure for it.
What is the Dyson V11 noise level?
The Dyson V11 noise level, on the current US sheet, is 82 dBA for carpet and 87 dBA for hardwood in Boost, a 2023 document for the Motorbar version Dyson sells to businesses for $569.99.
Older sheets tell a different story. Dyson's earlier US V11 sheet, for the High Torque head version, lists "Handheld Boost mode 88 dBA", and the Australian V11 Extra sheet also gives 88 for handheld Boost.
Those are not a louder V11 so much as a different test condition: wand off, held in the hand, no floor named. Match the head on any V11 you buy to the sheet before quoting either figure.
Is the Gen5detect louder than the V15 Detect?
Yes, by two dBA on Dyson's own sheets: 84 dBA for the Gen5detect against 82 for the V15 Detect, both in Boost on carpet. The Gen5detect figure comes from Dyson Australia and New Zealand, since no US document gives one.
The Gen5detect also draws more power. Its Australian sheet lists 752W and 262 AW, against the 545W on the V15 sheet, and its motor spins at 135,000rpm instead of 125,000.
Dyson's US page sells the Gen5detect for $719.99 and lists both the Fluffy Optic and Digital Motorbar heads in its specifications, yet its in-the-box list names only the Fluffy Optic. The 84 dBA belongs to the Digital Motorbar, so check which heads your box holds.
How loud is the Dyson Car+Boat handheld?
The Dyson Car+Boat lists "Sound power level: HP82 dBa" on its US sheet, dated 4.1.2025, with no mode, tool or distance named. It is Dyson's only handheld vacuum with a published figure.
Dyson gives the Car+Boat two power modes, 19.8 Air Watts in Powerful mode and 116 in Boost, and the sheet lists five minutes in Max mode. Which setting the HP82 figure describes, the sheet does not say.
The US product page adds that acoustic felt and closed-cell foam "absorb vibrations, to reduce noise." Our handheld vacuum guide sets the Car+Boat beside other makers' hand vacs.
Which Dyson vacuums have no decibel rating?
Most current US Dysons have no decibel rating: the V8 Cyclone, V12 Detect Slim, V10 Konical, V16 Piston Animal, V15s Detect Submarine, Gen5outsize, PencilVac, Ball Animal 3, Big Ball Turbine, the wet cleaners and every robot.
Their US pages give suction, weight and run time in a specifications table with no sound row. The Ball Animal 3, a corded upright with a 50 ft cord and 290 AW, showed out of stock at $449.99, and the Complete version at $599.99.
We also checked Dyson's business documents for Canada, Australia and Singapore and sample pages from its German, Japanese and UK stores. None added a figure for these models, so they appear here unranked, not as quiet or loud.
Are Dyson robot vacuums quiet?
Dyson robot vacuums have a Quiet mode, but Dyson publishes no decibel figure for any of them. The Spot+Scrub Ai, $1,199.99, offers "four different cleaning modes: Auto, Quick, Quiet or Boost".
Dyson's FAQ for that robot says it "features a Quiet mode setting if you'd like to clean your home without making too much noise, or disturbing a sleeping partner or child." The R1 Nurovi Dry, $549.99, and the R3 Nurovi Spot+Scrub UV, $1,199.99, print no figure either.
Robot makers that do publish numbers are compared in our robot vacuum guide.
Does Dyson make a silent vacuum?
No, Dyson does not call any of its vacuums silent. Its pages prefer "Acoustically engineered", which the V11 for business page explains as "Designed to absorb vibrations and dampen noise to keep sound levels down."
An 82 dBA sound power rating describes the total acoustic energy the machine sends out in Boost, which is a lot. What you hear at arm's length is lower than the sound power number, by an amount Dyson does not publish.
What does dBA of sound power mean on a Dyson sheet?
Sound power, the quantity on every Dyson vacuum sheet, describes the noise a machine emits in total, independent of where a listener stands. Sound pressure, which some other vacuum makers print, is measured at a set distance from the machine and reads lower.
That is why Dyson's 82 dBA cannot be set beside a rival's 70 dB(A) sound pressure figure, or a figure that names no quantity. Our sound power and sound pressure explainer covers the difference, and comparing decibel ratings shows how to read mixed labels.
Inside Dyson the labels are consistent: every vacuum figure says sound power, and all three stick ratings name Boost, which is what lets those three be ranked.
