People search for Tineco vacuum decibels because Tineco sells on quiet. Its pages say "Whisper-Quiet Operation", "Low Noise Operation" and "Quiet Mode". The numbers behind those words are harder to find, and they come from three different places: a spec table, a stock answer in the store Q&A, and the marketing images for the floor washers' drying cycle.
We opened every vacuum and floor washer on Tineco's US store, its matching product page on us.tineco.com, the text inside each page image and the user manual where Tineco links one. This page lists every published figure for a current model, says where it came from and what Tineco ties it to, and ranks each figure only against others of the same kind. Stick vacuums and floor washers stay in separate lists.
Our picks are listed above, with full specifications for each.
Tineco uses three units across its range, and it does not explain any of them:
- Plain dB on the two stick vacuums, in a spec table row called "Noise Level".
- dB(A) on the FLOOR ONE S5 spec table and on most drying images. The A means the reading is weighted the way the ear hears; our dBA explainer covers what that changes.
- dBA in the store Q&A and on a few drying images. Tineco uses dBA and dB(A) for the same figure on one model, the S7 Suite, so we treat those two as one unit. We do not rank plain dB against either.
Tineco never states a measuring distance, never says whether a figure is sound power or sound pressure, and names a mode only for drying. The footnotes say "Based on Tineco's lab data", and one adds "actual results may vary depending on your home environment and user habits." Several figures are printed with a less-than-or-equal sign, which makes them ceilings, not typical readings.
Nine stick vacuums are on Tineco's US store. Two publish a figure, both in the same spec table format:
- A30S: "Noise Level 67.1 dB". 160W suction, up to 60 minutes. $229.00 list.
- PURE ONE A50S: "Noise Level 70 dB". 185W suction, up to 70 minutes. $329.00 list.
The gap is 2.9 dB, which is small. With no mode named for either, it may simply reflect different settings. Treat it as a slight edge, not a clear difference.
We found no figure anywhere for the PURE ONE S20, S30, S50 Pro, S70, A90S, Station 5 or Station 5 Pro. The S70 and S50 Pro manuals say they start in AUTO mode by default, the S30 and S50 manuals show ECO, MED and MAX, and the A50S store page says "Higher suction modes naturally generate more airflow noise". None of that comes with a number.
This contradicts our own earlier note. Our quietest vacuums guide says Tineco's current lineup publishes no figure, because the older models it checked had left Tineco's store. The A30S and A50S are current and carry one; we found them on this closer read.
Tineco's floor washers vacuum and wash hard floors in one pass. They are louder machines than a stick vacuum on Tineco's own figures, and we keep them in their own groups.
In a spec table
- FLOOR ONE S5: "Noise 78dB(A)", also printed in a page image as "78dB(A) Low Noise Operation". $349.99 list.
In the store Q&A, as a ceiling in dBA, lowest first
- Up to 78dBA: FLOOR ONE S6 Master, S7 Artist, S7 Master, S7 Stretch Steam, S7 Stretch Ultra, S7 Suite, S9 Artist Pro, S9 Artist Steam and S9 Master. Each page answers "How noisy is the floor washer?" with "The floor washer produces up to 78dBA of sound."
- Up to 80dBA: FLOOR ONE i6 Stretch, i7 HotWash, S6 Stretch Steam, Stretch S6 and the GO H2O HammerHead Mess Detect Complete, with "The floor washer produces up to 80dBA of sound."
Read this group as a family answer, not a model figure. The Q&A blocks are clearly shared: on the S7 Suite page the same Q&A describes a "25.2V 4000mAh battery" with 30 to 40 minutes of runtime and names the "Floor One S7 Pro", while the page's own spec says "Up to 70 minutes". On the GO H2O page, the answer sits beside one about "the Steam". The 2 dB between the two answers is the only ranking we make here, and it is a ranking of Tineco's two stock answers.
The FLOOR ONE STATION S9 Scientist Pro and the iFloor 5 publish no cleaning figure, and neither do the two Carpet One Cruiser carpet cleaners. The Cruiser page does answer "so loud during self-cleaning?" by saying the cycle "naturally creates more noise than standard cleaning mode", without a number.
The drying cycle is where Tineco is most specific
Most FLOOR ONE S-series models clean their own roller in the dock with heated water, then dry it with hot air. Tineco offers two drying cycles: FlashDry, about 5 minutes, and SilentDry, about 40 minutes and quieter. Tineco's images say "Press and hold for 3 seconds to switch to SilentDry Self-Cleaning system". These are the only Tineco figures tied to a named setting, so they are the most useful ones here.
SilentDry, as a ceiling, lowest first
- FLOOR ONE S7 Suite: "switch to SilentDry at no more than 40 dB(A)", and "≤40dBA" in its images. $699.00 list.
- FLOOR ONE STATION S9 Scientist Pro: "SilentDry operates at ≤40dB(A)* for quieter drying". $1,199.00 list.
- FLOOR ONE S7 Stretch Steam: "SilentDry mode for a quiet 40-minute operation at ≤45 dBA". $699.00 list.
- FLOOR ONE S7 Master: "≤52 dB(A) (SilentDry Mode)". $599.00 list.
- FLOOR ONE S9 Master: "SilentDry mode ≤52 dB(A)*". $699.00 list.
- FLOOR ONE S6 Master: "≤65* dB(A)" on its store page and in most images, but "≤62* dB(A)" in large type on one image on its US product page. $499.00 list.
That spread matters more than it looks. Roughly every 10 dB sounds about twice as loud, so a 40 dB(A) ceiling against 52 or 65 is a real difference in a quiet room at night, while the 78 to 80 dBA cleaning answers sit far above every drying figure. Our decibel chart sets these numbers next to everyday sounds. Drying also runs after you have finished, often in the evening, so this is the figure that reaches a sleeping household.
FlashDry has no published figure on any model. Tineco calls SilentDry the quieter one, so expect FlashDry to be louder for its 5 minutes.
What changes the noise between Tineco models
Tineco does not publish figures by mode, but its pages and manuals point to the same causes:
- Suction mode. The A50S store page says "Higher suction modes naturally generate more airflow noise." Its manual lists ECO, AUTO and MAX. The S70 and S50 Pro start in AUTO by default.
- Auto adjustment. Tineco's iLoop sensor "Detects hidden dust and debris and auto-adjusts suction power in real-time" (A30S page). That means a Tineco in AUTO will get louder on a dirty patch, which none of the figures shows.
- Self-cleaning and docks. The Carpet One Cruiser page says its self-clean cycle "combines suction, water flushing, and heated drying". The Station 5 page says its auto-empty "naturally creates short bursts of higher noise". Neither has a figure.
Tineco's quiet features, by their real names
SilentDry. The 40 minute drying cycle above, with a figure on six models.
QUIET Mode. On several floor washers, including the S6 Master ("Always ready for use with lower noise levels"), the S7 Suite ("Low-decibel operation in Quiet Mode. Enjoy undisturbed rest for everyone at home") and the S9 Master, whose spec lists "Quiet mode: 65min" of runtime. Tineco publishes no figure for QUIET Mode itself, only longer runtime.
Smart Noise Optimization. A feature name on the older PURE ONE S15 and PURE ONE X pages, with no explanation of what it does.
Voice prompts. The FLOOR ONE manuals say a mute button turns the voice prompts off or adjusts the volume, which is worth doing if you clean while others sleep.
How Tineco compares
This page ranks Tineco models only against each other. For how Tineco's stick vacuums sit among other brands, on each maker's published figures, see our quietest cordless stick vacuums guide. Since Tineco states no distance and no mode, read our explainer on why decibel ratings rarely compare across brands before treating a few decibels as a real gap. If pet hair is the job, our pet hair stick vacuum guide covers Tineco's FurFree kit and what other makers publish at full power. We do not yet have a floor washer guide, so there is no cross-brand ranking for those.
Models we did not rank
Tineco's US site still has pages for older models that are not on its US store, so we have not ranked them. The PURE ONE X page says it "reduces noise to as low as 70 dBA". The PURE ONE S15 page lists "Noise 78dB(A)" in its specifications and shows "≤80 Db(A) Low Noise Operation" in an image. The PURE ONE Station FurFree page says "Operating at only 78 dB(A)" in its text and "Noise 76dB(A)" in its specifications. If you find one of these on sale elsewhere, those are Tineco's figures for it, and the FurFree's two numbers do not agree.
How we chose
We listed every vacuum, floor washer and carpet cleaner on Tineco's US store, opened each store page and its us.tineco.com product page, read the text inside every image on both, and checked the US user manuals Tineco links, none of which carried a noise figure. We recorded each figure in Tineco's words with its unit, any sign in front of it and any mode or cycle it names, then grouped figures by source and unit and ranked only within a group. Prices are Tineco's US list prices on October 6, 2026; every model was on sale below list when we checked, and the sale prices are noted in each pick.
We did not measure any of these machines. Every figure here is Tineco's own, from its product pages, and Tineco states no measuring distance or mode for any cleaning figure. Your floors, rooms and the mode you choose will change what you hear, and nothing here covers MAX, the setting where a Tineco is loudest.
