Tineco Pure One S70 Review vs. Floor One S3 Ultra Review: FAQ From Someone Who Bought Both

Since fall 2019, I have been the person in my house who reads the manuals and researches floor-care gear before we spend money on it. I have also made, and documented, three significant buying mistakes that cost us roughly $1,100 in total. Two of those mistakes weren't about bad machines. They were about buying the wrong type of machine for the wrong type of home.

If you are here because tineco pure one s70 review and tineco floor one s3 ultra review are both open in different tabs, this FAQ is the shortcut I wish I had found. No long intro. Just the questions you should actually ask before ordering.

1. Tineco Pure One S70 or Floor One S3 Ultra: which do I get first?

First, these two are not really rivals. The Pure One S70 is a cordless stick vacuum. The Floor One S3 Ultra is a cordless wet-dry floor washer. One is built for dry messes on hard floors and carpet. The other scrubs hard floors and sucks the dirty water up in the same pass.

I went back and forth between the two for two weeks. On paper, the S70 made more sense because we have a fair amount of carpet. So I bought the S70 first. It was the right call for daily vacuuming, but it didn't solve the hard-floor problem. The kitchen, entry, and bathrooms still needed mopping, and the mop still annoyed me. A few months later I added the Floor One S3 Ultra.

If I had to do it over, I'd base the first purchase on one question: how much of your home is hard surface? If it's more than half, start with the Floor One S3 Ultra. It handles loose crumbs and pet hair on hard floors well enough that the stick vac becomes the second machine. If you're mostly carpet, get the Pure One S70 first. The S3 Ultra is a complement, not a replacement for carpet vacuuming.

2. Tineco Floor One S3 Ultra review: do you still need a mop and a vacuum?

On hard floors, no. That's the honest short answer. For regular maintenance, the S3 Ultra does what a vacuum and mop used to do in two separate steps. The brush roller wets and scrubs, and the suction pulls the dirty water and debris into the dirty tank. You don't sweep first, and you don't go back with a mop afterward.

But notice I keep saying hard floors. The S3 Ultra is not a carpet deep-cleaner, and it won't clean your sofa or curtains. You still want a vacuum if you own rugs, carpets, or upholstery. That's where the Pure One S70 fits in my house.

One thing that surprised me: it handles messy spills better than I expected. Coffee, crumbs, tracked-in mud, pet accidents on tile—all of it went into the dirty tank instead of spreading around. That said, don't treat it like a shop vac. Large solid debris is still better picked up by hand or a dry vacuum first.

3. Tineco Pure One S70 review: how well does it actually handle pet hair?

Good, but let me be specific about what good means. We have a 55-pound dog who sheds enough to build a second dog every spring. In auto mode, the S70 senses when there's more debris and bumps up suction on its own. On hard floors, pet hair disappeared into the bin on the first pass.

On our low-pile rug, I had to go slower and make two passes to pick up hair that was really ground in. The front light helped me see the fine fur that's usually invisible until it rolls into little tumbleweeds. That was the pleasant surprise.

The caveat nobody puts in the highlights: hair still wraps around the brush roll eventually. It's not terrible, and not after every use, but every few weeks I spend a few minutes cutting hair off the roller. If you skip that, the brush stops spinning as well. Not a dealbreaker, just a fact of owning any vacuum in a house with pets.

4. What is FlashDry on the Floor One S3 Ultra, and do I actually need it?

I almost didn't care about this feature. Then I remembered every mop and floor washer I had used before. Leave a wet roller or mop head sitting in a dark base for a couple of days, and it starts to smell like a damp towel. That sour smell is exactly what FlashDry is trying to prevent.

After a mopping session, the S3 Ultra runs a self-cleaning cycle. FlashDry then helps dry the roller and keeps the floor from staying as wet after cleaning. In practical terms, I can walk on the floor much sooner, and the machine doesn't develop that mildew smell between uses.

Is it worth paying for? Based on my experience, yes. The difference between a floor washer that dries its own roller and one that sits there wet is the difference between grabbing the machine because it's ready and dreading the odor.

5. How long do the batteries actually last in real life?

Take any advertised battery number and mentally cut it down for real-world use. Advertised runtimes are measured on lower power settings, not the auto or max modes you'll actually use.

In my house, I get through an ordinary three-bedroom cleaning session on one charge with the S3 Ultra. With the S70, I finish the carpets and hard floors before the battery gets into the red, but I'm not doing a 45-minute deep clean every day either.

If you have a large home, look at the runtime in the mode you plan to use, not the maximum number in the spec sheet. For our size, battery life hasn't been a problem. For a bigger house, you'd likely need to charge between rooms or buy a second battery if the model supports it.

6. Self-cleaning means I don't have to clean the machine, right?

It means less cleaning, not zero cleaning. I think this is the biggest expectation gap in this whole category. After using the S3 Ultra, these are the real tasks:

• Empty and rinse the dirty water tank after each use.
• Run the self-cleaning cycle before the dirty water dries in the machine.
• Check the roller and base tray for hair or debris every few sessions.

The Pure One S70 is simpler, but it still needs the dust bin emptied regularly and the filter washed every few weeks. Skip that and suction drops, and you'll blame the vacuum when the real issue is the filter.

If you are the type of person who hates cleaning a traditional vacuum, be honest with yourself. This is not a no-maintenance purchase. It's a trade: you spend less time mopping and vacuuming, and more time maintaining a machine that does both.

7. What is the biggest mistake people make when buying one of these?

Trying to pick the winner before mapping out their actual floors. I still kick myself for doing exactly that. I compared specs and read reviews for weeks, then bought the machine that was more impressive on paper instead of the one that matched my daily mess.

The second mistake is assuming the higher-end model automatically means it's better for you. A floor washer is not better than a stick vacuum. It's different. If you have mostly carpet and you buy a floor washer first, you'll be frustrated. If you have mostly hard floors and you buy a stick vacuum first, you'll still end up mopping.

Start with your floor plan, not the marketing. Ask which mess bothers you most each week: vacuuming the carpet or mopping the hard floors. That answer will tell you whether your first Tineco should be the Pure One S70 or the Floor One S3 Ultra. The second one can come later, and for most people, that's exactly how it works out.
