Tineco Floor ONE S9 Artist Steam
Best overallThe best all-in-one hard floor cleaner available right now, combining vacuuming, mopping, and genuine steam cleaning in a single pass, but the flagship price only makes sense if you'll actually use the steam function regularly.
What We Like
- Best-in-class cleaning performance with 320°F steam that removes dried and stuck-on stains
- DualBlock anti-tangle system continuously removes hair from roller during operation
- Triple-sided edge cleaning reaches walls and corners from front and both sides
- Up to 75 minutes runtime in Eco mode covers large homes on a single charge
- 360-degree SmoothDrive self-propulsion does most of the pushing for you
What We Don't
- Premium pricing is hard to justify without regular steam use
- Tineco publishes no weight, and retailers disagree slightly (9.5 to 10.1 lbs)
- Self-drying must be manually initiated rather than starting automatically when docked
- Steam mode cuts battery life to approximately 30 minutes
A grand. That’s what Tineco wants for the Floor ONE S9 Artist Steam, their top-of-the-line wet-dry vacuum with integrated steam. It costs roughly double the increasingly impressive options from Dreame and Dyson. Nine hundred and ninety-nine dollars (MSRP).
So the question isn’t whether this machine is good. It is. The question is whether it’s twice-the-price-better than a Dreame H14 Pro or worth the premium over Dyson’s Clean+Wash Hygiene. What follows works through that from Tineco’s specifications and Vacuum Wars’ published test results, which currently rank it first among hard floor cleaners.
What Steam Actually Does (and Doesn’t Do)
First, let’s kill a misconception. Steam doesn’t make a wet-dry vacuum clean better in the way most people think. It doesn’t blast grime off your floor like a pressure washer. What it does is sanitise. The S9 heats water to 320F internally, though Tineco is careful to say that’s the heater figure, not the outlet temperature. What reaches the roller and your floor, by Tineco’s account, doesn’t fall below 210F.
If you’ve got a baby crawling around, a dog who tracks in questionable things from the garden, or you’re just the sort of person who wants genuinely sanitised floors rather than floors that merely look clean, steam matters. If you don’t care about sanitisation, you’re paying a hefty premium for a feature you won’t use, and you should look elsewhere.
Steam earns its place on dried-on food, because heat softens residue that a cold roller has to scrub at. That’s the one cleaning job where it changes the result rather than just the hygiene.
Real talk though: the 30-minute steam runtime is limiting. Your clean water tank is 0.88 litres and steam mode chews through it faster than standard mopping. If you’ve got a large open-plan space, expect to refill partway through.
Cleaning Performance
Forget the marketing videos of someone gliding over a perfectly staged spill. The independent numbers come from Vacuum Wars, and they’re strong. On its dried coffee stain test the S9 scored 151 points against a category average of 140, and its combined mopping score of 175 tied for first place among every hard floor cleaner it has tested. It also left 0.4 grams of water behind against a 1 gram average, so floors dry faster.
On paper the dry side is well served too: Tineco quotes 22 kPa of suction from a 285W motor, and the iLoop sensor adjusts power and water flow to what it detects. Heavy mess, red ring, more suction. Clean floor, blue ring, dials it back. The dual-tank system keeps clean water going to the roller and dirty water separate, so you’re not pushing filth around.
DualBlock Anti-Tangle and Triple Edge Cleaning
Hair. The eternal enemy of roller-based cleaning machines.
Tineco’s DualBlock system uses a dual-scraper design that prevents hair from wrapping around the brush roller during operation. In a shedding household that is the difference between a roller you clear after every session and one you mostly leave alone, which is the most common complaint about wet-dry cleaners generally.
The triple-sided edge cleaning is the other headline feature. Most wet-dry vacuums leave a 1-2 inch gap along baseboards because the roller sits recessed inside the cleaning head. The S9 extends cleaning capability on three sides: left, right, and front.
Edge cleaning is the underrated part. Kitchen islands and plinths collect crumbs in a strip most floor cleaners leave behind, and the S9 reaches it on three sides. It’s a small thing that removes a job you’d otherwise do by hand every time.
The Weight Problem (and Self-Propulsion Solution)
At roughly 10 lbs, the S9 is lighter than most of its rivals, which is easy to miss given how much it packs in. It undercuts the 12.57-pound Dreame H14 Pro comfortably, and the 10.47-pound Roborock F25 ACE Combo by a whisker. Tineco doesn’t publish a weight, so that figure comes from retailers: Best Buy lists 10.1 lbs, Amazon 9.48.
Tineco’s answer is 360-degree SmoothDrive self-propulsion. The machine drives itself forward and pulls back with motorised assistance, so you’re guiding rather than pushing. Vacuum Wars, which weighed its unit at over 13.5 pounds, found the self-propel system offsets that significantly and called it easy to manoeuvre.
But. And this is a meaningful but. Self-propulsion can’t help with vertical lifting, and a machine carrying two water tanks weighs more in use than its empty figure suggests. Lifting it over a threshold or upstairs to a bathroom is where you notice it. If you’ve got wrist or shoulder issues, try it in a shop before committing.
For a two-storey home, think about whether you want to carry it up and down stairs regularly.
Smart Features and App Control
The LCD display on the handle shows battery percentage, cleaning mode, water level, and iLoop status.
The Tineco app connects via WiFi and offers cleaning reports, reminders for roller replacement, and firmware updates. The handle display covers the same basics, so the app is optional for day-to-day cleaning.
Self-Cleaning: Good but Not Automatic
Tineco calls it FlashDry. After your cleaning session, you dock the machine and press the self-clean button. It flushes the roller with fresh water, rinses the internal pathways, then blasts 185F hot air through the system to dry everything. Takes about five minutes.
The hot-air drying is the key part. Wet rollers left in a sealed machine grow bacteria and start to smell. The 185F air is there to stop that.
My gripe: you have to initiate self-cleaning manually every time. The Dyson Clean+Wash Hygiene runs its flush automatically when you dock it, then the hot-air cycle kicks in. The S9 just sits there until you press the button. If you forget after a long day and leave it overnight with a wet roller, you’ll notice the smell the next morning. It won’t damage anything, but it defeats the purpose of having a self-clean system.
Tineco should make this automatic. A machine at this price shouldn’t rely on you remembering to press a button after every session.
Battery and Runtime
Tineco rates it at 75 minutes in the flat position, and Vacuum Wars measured exactly that: 75 minutes, tied for first place and roughly double the 35-minute average across the hard floor cleaners it has tested.
Steam mode cuts that to roughly 30 minutes, as mentioned. The 3.5-hour charge time is average for this battery size. Nothing special, nothing terrible.
For reference: the Dreame H14 Pro manages 40 minutes, the Dyson Clean+Wash Hygiene hits up to 70 minutes, and Roborock rates the F25 ACE Combo at 60 minutes in Eco. The S9’s 75 minutes in Auto gives it a genuine edge for larger homes.
Who Should Buy the S9 Artist Steam
You want this machine if you need genuine floor sanitisation without chemicals. Parents with crawling babies. Pet owners whose dogs treat every walk like a mud bath. Anyone with a compromised immune system in the household. The 320F steam is the real differentiator, and nothing else in this price range offers it at this temperature.
You also want it if you’ve got a larger floor area and need the 75-minute runtime. And if hair tangles drive you mad, the DualBlock system is designed for exactly that problem.
You don’t want this machine if a grand feels like too much for a floor cleaner. Because it is a lot. The Dreame H14 Pro at half the MSRP covers daily messes without the steam, lies flat to get under furniture, and weighs a pound less. If steam sanitisation doesn’t matter to you, the Dreame is the smarter buy.
You also don’t want it if you have lots of low furniture. The S9 does lie flat at 180 degrees, but its 12.85 cm (5.06 inches) clearance height means it won’t fit under anything particularly low. The Dreame’s lie-flat clears just 3.86 inches. That inch-plus difference matters if your sofa or bed frame sits close to the floor.
Verdict
The Tineco Floor ONE S9 Artist Steam is about as good as wet-dry cleaning currently gets. Its mopping score ties for first in Vacuum Wars’ testing, the steam is hot enough to matter, triple edge cleaning targets the baseboard gap, and 75 measured minutes of runtime gives you breathing room that cheaper machines don’t.
But “best” and “best value” aren’t the same thing. At its flagship price, you’re paying a steep premium for steam and edge cleaning over machines that handle 90% of daily floor messes just as competently. The self-clean system should be automatic at this price. And 30 minutes of steam runtime will frustrate anyone with a large home.
If you can afford it and you genuinely need steam sanitisation, buy it. You won’t be disappointed. If you’re on the fence about steam and just want clean floors, save the difference and get the Dreame. Your floors won’t know the difference on a Tuesday afternoon with dried cereal and coffee drips.

Frequently Asked Questions
- Can the Tineco S9 Artist Steam replace a regular mop?
- Yes. It vacuums, mops, and steam-sanitises in a single pass, so there's no need for a separate mop. You'll still want a traditional vacuum for carpeted rooms since the S9 is hard-floor only.
- How long does the steam last on a full tank?
- About 30 minutes in steam mode. The clean water tank is 0.88 litres and the steam function draws from it more aggressively than standard mopping. In Auto mode without steam, runtime stretches to 75 minutes.
- Does the Tineco S9 Artist Steam work on hardwood floors?
- It works on sealed hardwood, tile, laminate, vinyl, and stone. Avoid unsealed wood or heat-sensitive flooring. Check your flooring manufacturer's guidance before using any steam cleaner.
- What's the difference between the S9 Artist Steam and the S7 Steam?
- The S9 runs hotter steam (320F vs 266F), adds DualBlock anti-tangle tech, includes triple-sided edge cleaning, and has a longer 75-minute runtime in Auto. It costs significantly more, though it is not the heavier machine: retailers put the S9 at roughly 10 lbs.
- How does the FlashDry self-cleaning work?
- Place the S9 on its dock and press self-clean. It flushes the roller and internals with water, then blasts 185F hot air to dry everything out. You don't need to remember to run it, but you do need to press the button manually each time.
