Noise level

Cleaning and especially the drying cycle are often described as unusually quiet for the category, with some reviewers measuring roughly 39 to 43 dB during roller drying. Quiet mode cleaning is also noted as comfortable for home use.

Multiple reviewers highlight unusually quiet operation for a vacuum-mop robot, making it easier to run while people are home.

Noise is a standout strength: measured levels are relatively low on standard modes and many users describe it as quieter than competing cordless sticks.

Noise is often described as relatively quiet for a cordless stick, with one review measuring around mid-60 dB in normal use and higher readings closer to the high-70s on max. Overall, it trends quieter than many competing cordless vacuums in comparable power.

Noise is often described as quieter than similar cordless sticks, making it easier to use for quick daily cleanups without feeling disruptive.

Day-to-day running noise is repeatedly called out as very quiet for a flagship combo, making it easier to run while working or sleeping.

Noise is generally a non-issue, with quiet modes around the low-50 dB range in at least one test and few complaints about loud operation.

Generally quieter than many competitors; peak loudness is cited around 70 dB on higher suction, and real-home testing reports low disruption (pets barely reacting).

Noise levels are commonly praised as quiet for its class, with multiple reviewers specifically calling out how subdued it sounds during operation.

Noise levels are generally reported as relatively quiet for a stick vacuum, with multiple measurements cited around the ~70–76 dB range depending on the source/test.

Consistently described as quiet in Eco/Mid and still reasonable on Turbo, often less likely to spook pets than typical stick vacs.

At least one hands-on reviewer found it surprisingly quiet for the level of suction. Most sources do not provide detailed noise measurements, so expectations should be set as generally acceptable rather than whisper-quiet.

Noise is generally acceptable: mop mode is often described as quiet, while Boost/Turbo vacuuming gets noticeably loud.

Noise is commonly described as relatively quiet for its performance, with measured results in the mid-50s to low-70s dB depending on mode and attachments.

Multiple reviewers highlight that the V8 is noticeably quieter than many newer, higher-powered Dysons, especially with the fluffy/soft roller head. Max mode is louder, but normal mode is often described as easy to live with.

Noise is repeatedly described as low for a flagship combo robot, especially in mopping mode; self-empty events are audible but generally not extreme.

Noise is described as quiet in use, including a 73 dB max-power measurement in one review and an owner noting their dog was not bothered by it.

Noise is generally described as reasonable for a flagship robot, with several notes that mopping is especially quiet. Vacuuming at max power can still be loud, but it’s not a standout complaint overall.

One reviewer calls the V11 notably quiet for a cordless vacuum, especially given its power. Noise level is not a major complaint elsewhere in the review set.

During cleaning, noise is commonly described as moderate to fairly quiet for a robot vacuum, especially on carpet; the main noise complaint centers on the dock, not the robot itself.

Frequently described as relatively quiet for a handheld vacuum. Reported measurements vary by test setup, ranging from low-70s dB to low-80s dB.

Operational noise is generally described positively (quiet or unobtrusive), and some coverage suggests BLAST aims to improve performance without a big noise penalty. Few reviews provide direct measurements, so perceptions dominate.

Multiple reviewers call it notably quiet, with measurements ranging from low‑50s dB to the mid‑60s dB depending on surface and power; warning beeps when stuck can be more noticeable than the motor noise.

Noise levels are often described as relatively quiet for a cordless vacuum, with some testing placing it in the mid-60 dB range depending on mode.

In-run noise is frequently called quiet, with higher suction audible but not disruptive. The biggest spikes happen at the dock during auto-empty or maintenance cycles.

Noise is typically described as low for the suction on offer, with measured figures often landing in the mid‑60s to around 80 dB depending on setting and head. Turbo heads can add sound, but most still find it bearable.

Generally described as quiet during cleaning, with some notes that collisions/bumping can create louder momentary noise than the suction itself; higher suction settings increase volume.

Often described as quiet for its performance (some measurements/estimates around low‑50 dB), though max power is still noticeable.

Often described as unusually quiet for its power, though one measurement-style test notes max power can be louder than average—lower modes help keep it unobtrusive.

Most reviewers call the C3 relatively quiet for its power—especially on lower settings—and some cite “silent” design elements. Turbo/electric heads can add noticeable noise compared with suction-only hard-floor tools.

Multiple reviews call it notably quiet for a powerful canister, with measured noise in the mid-70 dB range in one test. The ComfortClean/self-clean routine can make a distinct clunking sound even though normal cleaning stays refined.

Noise is generally framed as reasonable/quiet by at least one hands-on unboxing, while another source cites around ~70 dB, suggesting a moderate sound level for the category.

Noise is generally manageable, and some variants emphasize adjustable suction to trade power for quieter operation; one review describes an especially quiet experience on a specific model.

Noise is described as relatively low during mopping at lower water flow and acceptable during standard vacuuming. The loudest moments tend to be MAX+ suction and the brief auto-empty cycle at the dock, which reviewers note is quick.

Most reviewers call Henry notably quiet for its power, with one citing about 72 dB. A few older or modified units sound higher-pitched, but the overall noise profile is still viewed as low.

Operational noise is frequently rated favorably for a robot vacuum, with comparative testing placing Q Revo models among the quieter options overall, though high-power modes and auto-empty events remain clearly audible.

Vacuuming is often described as quieter than expected for its power, with measured mid-to-high 60 dB reports in some tests.

Noise impressions vary: some call it very quiet in normal use, while measured max-power runs are above average and not ideal for TV/nap time in the same room. Noise is highly mode-dependent.

Noise impressions are generally positive for the category, with reviewers calling it quieter than expected; one source cites a Quiet Mark rating and another measures roughly 82 dB on default and 89 dB on boost.

Noise is described as relatively quiet for a cordless, with lab-style measurement commentary placing it a bit better (quieter) than the category average.

Noise is generally considered reasonable for the power and is noted as quieter than newer Dyson cordless models in comparisons. Max mode is louder, but still viewed as manageable in normal household use.

Noise is frequently described as relatively quiet for an upright; at least one test set places it among the quietest in its comparison group.

Measured cleaning noise is often in the quiet-to-moderate range, while the auto-empty cycle is much louder; most reviews consider it acceptable for daytime use.

Noise is described as reasonable for a powerful cordless; some call it not super loud/quiet enough for the category, though motorized tools can squeal in certain angles/pressure.

Noise is typically described as relatively quiet for its power, with some measurements cited in the low-to-mid 70s dB range; the AiroBrush/turbine head is often louder than the standard combi head.
