How Loud Is a Vacuum Cleaner? (About 70–80 dB)
Quick answer
70–80 dB
A vacuum cleaner measures 70–80 dB at one metre — roughly the level of a busy restaurant. It is not loud enough to damage hearing during normal use, but it comfortably drowns out conversation and TV.
60 dB (quiet canister model) to 85 dB (older upright)

8+ hours at 75 dB; hearing risk is minimal at typical vacuum levels.

How a vacuum cleaner compares to other sounds
| Sound source | Decibel level | Relative loudness |
|---|---|---|
| Quiet canister vacuum | 60–68 dB | |
| Typical cordless stick vacuum | 72–78 dB | |
| Standard upright vacuum | 75–82 dB | |
| Older / shop vacuum | 83–90 dB | |
| Robot vacuum | 55–65 dB | |
| Normal conversation | 60 dB |
What counts as a 'quiet' vacuum
Manufacturers label anything under 70 dB as quiet. Because a 10 dB reduction is perceived as roughly half as loud, a 65 dB vacuum genuinely sounds like half the noise of an 80 dB one — even though the number only dropped by 15.
Hard floors and bare walls also raise the reading. The same machine can measure 4–6 dB higher in a tiled kitchen than in a carpeted bedroom.
Why vacuum noise annoys neighbours
Vacuum noise is broadband with strong low-frequency motor content, and low frequencies pass through floors and walls far more easily than high ones. That is why the person downstairs hears the rumble rather than the hiss.
In apartments, running a vacuum before 08:00 or after 22:00 is the single most common source of noise complaints after music.
Reducing the noise
Small maintenance details make a measurable difference.
- Empty the bin and clean filters — a clogged filter forces the motor to work harder and adds several dB
- Check for blockages in the hose, which cause high-pitched whistling
- Vacuum over rugs where possible; soft surfaces absorb reflected sound
- Choose a model rated under 70 dB if you clean while others sleep or work

How many decibels is a vacuum cleaner?
Most vacuums measure 70–80 dB at one metre. Premium quiet models reach 60–68 dB and robot vacuums are often below 65 dB.
Can a vacuum cleaner damage your hearing?
Not in normal use. At 75 dB you could be exposed for more than eight hours a day without risk. Only very loud shop vacuums above 85 dB warrant hearing protection.
Is 70 dB loud for a vacuum?
70 dB is at the quiet end for a full-size vacuum — comparable to a normal conversation held slightly louder than usual, and quiet enough to talk over.
