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)
measured 1 m from the machine
Typical levels are below NIOSH's 85 dBA 8-hour guideline; hearing risk in normal use is low.

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
Many manufacturers market models under about 70 dB as quiet. Because each 10 dB reduction sounds roughly half as loud, a 65 dB vacuum sounds about a third as loud as an 80 dB one — a bigger difference than the 15-point gap suggests.
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, vacuuming early in the morning or late in the evening is a common cause of neighbour complaints.
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 household use. Typical levels of 70–80 dB are below NIOSH's 85 dBA 8-hour recommended limit. Very loud shop vacuums used for long periods are the exception where protection makes sense.
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.

Exposure times follow NIOSH's occupational recommended exposure limit (85 dBA over 8 hours, 3 dB exchange rate). They are guidelines for limiting risk, not thresholds at which injury is certain.
