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.

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.

Often described as noticeably quieter than newer high-power Dysons, especially with the fluffy/soft roller head, while max mode is still loud; the lower-frequency sound makes cleaning less harsh on the ears.

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).

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

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

Reviewers commonly describe the robot as quiet during normal cleaning (often around the low-60dB range in testing), with most noise coming from brief dock auto-empty and maintenance bursts.

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.

Generally quieter than expected for a powerful corded canister, with users describing it as pleasantly quiet; still audible, but not as harsh as many full-size vacuums.

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.

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.

Most reviewers describe the HX2 Pro as relatively quiet for its power, with measured noise often below typical vacuum expectations when using the main floorhead.

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.

Cleaning noise is often described as relatively quiet for a robovac, while dock auto-emptying and wash cycles are noticeably louder (though brief); the mop-drying fan can run for hours at a low hum.

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 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.

Often described as fairly quiet for its power, with some listings around the low 70 dB range and in-use measurements ranging from the mid-70s into the high-80s depending on surface and head. The AiroBrush turbo head adds noticeable extra noise.

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 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 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.

Overall operating noise is described as relatively quiet for a flagship, though moments like max suction or dock cycles can still be noticeable and at least one reviewer flags it as loud.

Quiet in normal cleaning (high‑50s/60dB), loudest during max power and auto‑emptying.
