Tineco's Floor One Station S9 Scientist Pro is the only floor cleaner you need for wet and dry mess, provided your budget can take the hit

Tineco Floor One Station S9 Scientist Pro: two-minute review

In August 2026, Tineco launched its most advanced floor washer to date — the Tineco Floor One Station S9 Scientist Pro Wet and Dry Vacuum. With a suction power of up to 25,000 Pa, it’s one of the most powerful wet-dry vacuums on the market, picking up fine materials like flour in a single pass and large materials like 8-12 leaves in less than a minute. With the lie flat design, you can reach further under furniture. Side edge cleaning doesn’t get better than this. You can clean along the front of the vacuum up to about one-half to one-eighth of an inch. With a battery that lasts 65-75 minutes on Auto mode and up to 100 minutes on Quiet mode, you can clean most houses in a single go.

Thanks to four cleaning modes, including a dirt detect mode, the Tineco Floor ONE Station S9 Scientist Pro Wet and Dry Vacuum soared through our various cleaning tests from dry debris to wet messes and stubborn stains. A HydroBurst sprayer that can spray solution on tough stains is a great addition, but kind of unnecessary since the mopping power is exceptionally good. Not only does the wet-dry vacuum use hot water to clean (and continuously washes the brushroll as it mops), but the brushroll presses against the floor for a deeper clean and utilizes a streak-free scraper when the wet-dry vacuum goes in reverse. This helps to remove tough messes and prevent streaks or water stains.

The most notable upgrade, however, is the Smart Refresh Station. Tineco clearly took inspiration from robot vacuum bases and created a base that automatically refills the wet-dry vacuum with cleaning solution and clean water from a 5-liter water tank. This reduces the maintenance required, which is already impressive considering the base uses hot water and hot air to clean the brushroll. Maybe soon enough Tineco will surprise us with a base that removes dirty water and debris too.

Perhaps the biggest drawback to this wet-dry vacuum is the price. It’s one of the highest on the market. If you’re willing to do a little more maintenance, the Tineco Floor One S9 Artist Pro cleans just as well. Still, I can’t deny that the Floor ONE Station S9 Scientist Pro Wet and Dry Vacuum might do better with larger debris and is a great investment for those with larger homes who want to clean their space on a single charge.

Keep reading for my full review of the Tineco Floor ONE Station S9 Scientist Pro Wet and Dry Vacuum and see why it’s currently my favorite on the market.

Tineco Floor One Station S9 Scientist Pro: price and availability

• List price: $1,199 (about £880 / AU$1,660)
• Launch date: August 2026
• Availability: US

The Tineco Floor One Station S9 Scientist Pro Wet Dry Vacuum launched in the US in August 2026 at a list price of $1,199 (about £880 / AU$1,660), making it Tineco’s most expensive wet-dry vacuum and a premium-priced wet-dry vacuum on the wider market. It’s sold through Tineco, as well as third-party retailers like Amazon and Walmart.

The price is not surprising, considering it may be the first wet-dry vacuum to offer a base station that auto refills the unit with water and solution. I’ve been testing wet-dry vacuums for years, and though this isn’t new technology (in that we see it utilized with wet-dry robot vacuums), it is new for wet-dry vacuum bases. Add in the exceptional battery life, solution sprayer, and streak-free scraper technology, and this price makes sense.

Perhaps during the holidays, the Tineco Floor ONE Station S9 Scientist Pro will be discounted. For now, you could go with the equally exceptional Tineco Floor One S9 Artist Pro Wet Dry Vacuum if you’re willing to refill the water tank by hand. It’s usually $849, but it’s discounted to $599, and I can say firsthand that it has a similar cleaning prowess as the S9 Scientist Pro.

Tineco Floor One Station S9 Scientist Pro: design

• 180-degree lie-flat design for hard-to-reach places
• Four cleaning modes and a solution sprayer for tough stains
• Self-cleaning and clean water auto-refilling base

It took minutes to put the Tineco Floor One Station S9 Scientist Pro Wet Dry Vacuum together. All I had to do was remove it from the packaging, slot the handle into the unit, and put it to charge on the base. A bottle of cleaning solution, extra brushroll, and a cleaning brush were provided in the packaging.

The first few things I noticed about the design were the thickness of the vacuum head and the sleek rectangular box design of the body. It looks almost robotic-like, and as I delved further into the design, it makes a lot more sense why the vacuum looks the way it does.

The Tineco Floor ONE Station S9 Scientist Pro Wet Dry Vacuum is 30lbs, so it’s not lightweight, but thanks to a self-propel system, it doesn’t feel heavy. I liked that vacuum head and the body are flexible and twist and turn easily. The wet-dry vacuum can also lie 180-degree flat making it easy to reach under beds and sofas to clean. This is possible because the dirty water tank is on the back of the vacuum body and the clean water tank is on the top of the vacuum head — hence why the vacuum head is so bulky.

A streak-free scraper under the vacuum head lifts when you push the vacuum forward and drops when you pull it backwards, so that it can scrape excess water and tough stains. This results in a completely clean floor free of water stains and streaks. A white headlight helps to illuminate dark spaces, while a comb and scraper near the brushroll prevents the tangling of hair and other debris.

A small LED screen is placed on the handle with three buttons. The power button turns the unit on and off, while the change mode button lets you move between the four cleaning modes — Auto, Max, Quiet, and Suction. The mode in use and battery life appear on the LED screen. A HydroBurst button causes cleaning solution to spray from the front of the vacuum head onto tough stains.

Tineco has done something a bit different with the Floor One Station S9 Scientist Pro Wet Dry Vacuum in terms of the Auto Mode (or the dirt detect system). When using Auto Mode, a light blue digital ring on the front of the unit’s body appears. Parts of the ring turn red to notify you how dirty the floor is. The more red the ring is, the dirtier the floor.

While this digital display is intuitive, there are seven status displays in total that appear on the front of the vacuum’s body and not all of them are easy to remember. The seven displays are Dirt Level, Battery, HydroBurst, Self-Cleaning, Drying Mode, Malfunction, and Water Filling Indicators. Each one has a different shape and a different color indicator. This is probably the biggest design drawback for me, as I think Tineco could’ve displayed such indicators in an easier-to-understand method. With the voice commands, you’ll understand what each indicator means, but if you turn off the voice commands, you might find yourself slightly confused.

There is also a self-cleaning button on the top of the handle. It’s to be pressed when the wet-dry vacuum is on the base. Three buttons appear on top of the vacuum body when it’s on the base. The 'Hot Water Refill' button refills the wet-dry vacuum with hot water, while the 'Silent' button results in a longer brushroll drying period. The brushroll dries in five minutes if you press the 'Flash' button.

The base may be large, but consider this: it charges the wet-dry vacuum, self-cleans it with hot water and air, and auto refills the wet-dry vacuum’s clean water tank with water and cleaning solution. At the back of the base there is a cleaning solution compartment that can hold an entire bottle of Tineco cleaning solution. A 5-liter tank of clean water is then placed on top the cleaning solution compartment, so that when the wet-dry vacuum is on the base, the base can move hot water into the wet-dry vacuum hands-free.

While the design outshines other wet-dry vacuums on the market, I see some room for slight improvements in the future.

Tineco Floor One Station S9 Scientist Pro: performance

• Phenomenal cleaning capabilities with great edge cleaning
• Does a outstanding job suctioning liquids and large debris like leaves
• Front edge cleaning varies between ½ and 1/8th of an inch from the wall

From the get-go, I really liked how the handle of the the Tineco Floor One Station S9 Scientist Pro Wet Dry Vacuum twisted and turned so easily. This especially helped when I laid the wet-dry vacuum flat to clean under my bed. I was able to reach around the legs of my bedframe easily.

The dirt detection system was fantastic, recognizing even the smallest amounts of dust. My home is very dusty because it’s historic, and I was glad to see that the Tineco Floor One Station S9 Scientist Pro Wet Dry Vacuum suctioned up the dust rather than spreading it about or pushing it back into the air. The headlight illuminated dust and debris in dark spaces, though I would’ve preferred a green rather than a white headlight as green lights make dust and debris more visible. At least, I could trust the Auto Mode to 'see' hidden stains or dirt that I couldn’t see under the white headlight or with the naked eye.

The suctioning capabilities of the Tineco Floor One Station S9 Scientist Pro Wet Dry Vacuum are beyond impressive, which isn’t surprising considering it has a suction power of 25,000 Pa. (Trust me, that’s massive.) I used the wet-dry vacuum to pick up a lot of dried leaves that had fallen around one of my plants. I don’t think I’ve ever seen a wet-dry vacuum accomplish such a task in such a short time. Most struggle to suction one or two leaves, much less 10. Even the reverse cleaning was better than most wet-dry vacuums.

One of the first things I tested was the edge cleaning. There was no space between the wall and the side edge of the vacuum head. However, I noticed that there was about half an inch along the front edge of the vacuum head and the wall. That was a bit disappointing, until I realized that with certain things, like my really tall thresholds, the space shortened to about 1/8th of an inch. After some experimenting, I realized that if I approached the wall slowly with the front of the vacuum head, the front edge cleaning improved and I could clean closer to objects or walls.

Because the wet-dry vacuum’s head is so bulky, I couldn’t reach under cabinet overhangs. This has been my biggest gripe with wet-dry vacuums since they started putting the clean water tank on the top of the vacuum head because it means I have to go back through the house with a vacuum to clean those spaces.

The clean water tank lasted about 30 minutes (which is quite long), while the dirty water tank had to be emptied at about 40 minutes. These results are well above average.

While most people may use a robot vacuum or vacuum to clean daily, the Tineco Floor One Station S9 Scientist Pro Wet Dry Vacuum is a really great wet-dry vacuum to have on hand for weekly deep home cleanings and stubborn stains.

Cleaning tests

I ran several cleaning tests to see how well the Tineco Floor One Station S9 Scientist Pro Wet Dry Vacuum Cleaner cleans on Auto mode and was impressed with the results. I sprinkled flour, coffee, and crunchy oats on my laminate flooring, and spilled a variety of liquids like water, soy sauce, and barbeque sauce. I also place an egg on the ground and sprayed some chocolate sauce and siracha sauce and let them both dry slightly.

The Tineco Floor One Station S9 Scientist Pro Wet Dry Vacuum Cleaner picked up all the fine and large materials in a single pass, though some flour got stuck on the wheels when I reversed over the flour. The Suction mode did a fantastic job suctioning up the water. I used the Auto mode for the barbecue and soy sauces just to ensure the floor wasn’t sticky afterwards. It cleaned both sauces in a single go without any remaining residue.

While the wet-dry vacuum picked up the slightly dry siracha sauce in a single pass, it took about four passes to pick up the driest and thickest parts of chocolate sauce on auto mode. The thinner areas of the chocolate sauce only took a single pass.

I test a lot of wet-dry vacuums throughout the year, and Tineco consistently beats every other brand in cleaning capabilities. The Tineco Floor One Station S9 Scientist Pro Wet Dry Vacuum Cleaner didn’t disappoint, and proves that this wet-dry vacuum cleans the most consistently and effectively (and with less effort!) compared to others on the market.

Maintenance

The Tineco Floor One Station Scientist Pro Wet Dry Vacuum stands out among all wet-dry vacuums because of its base which is outfitted with a 5-liter water tank and a solution bay (that can hold a single solution bottle). The base automatically refills the wet-dry vacuum’s clean water tank in less than 30 seconds – and it’s pretty amazing to watch.

After each cleaning session, I placed the wet-dry vacuum on the base and ran the self-cleaning system which uses hot water to clean the brushroll. This hot water process is quite effective as the brushroll comes out super clean. I only found a very small amount of dust under the vacuum head when I removed the brushroll — far less than I have found with other wet-dry vacuums that I’ve tested.

Image 1 of 3

The base dries the brushroll and filter with hot air that’s 230 degrees Fahrenheit. Flash dry takes five minutes to dry the brushroll, while silent dry results in a quiet (40 dB sound rating) drying process. I wish I could say that the brushroll was completely dry when using either of these settings, but there was a very slight amount of dampness. On the flash dry setting, the brushroll was 95% dry, while the silent dry mode made the brushroll about 98% dry.

The only thing the base can’t do is empty the dirty water tank – so you have to do it by hand. A brush is provided by Tineco to remove debris. The debris catcher design could be better, but it catches a decent amount.

• Performance score: 4 out of 5

Tineco Floor ONE Station S9 Scientist Pro: battery life

The battery life of the Tineco Floor One Station Scientist Pro Wet Dry Vacuum is more than adequate for most homes. I was able to clean my 1,600-square-foot home in 30 minutes on Auto mode, and still have 50% of the battery life left.

Overall, the battery lasted between 65-73 minutes on Auto mode, which is in-line with Tineco’s predictions that the battery, on Auto mode, can last up to 75 minutes. Remember on Auto mode, the vacuum automatically increases the suction and cleaning power depending on how dirty the floors are. It could use more power and thus more battery life if your floors are especially dirty.

How I tested the Tineco Floor One Station S9 Scientist Pro

Testing the Tineco Floor One Station Scientist Pro Wet Dry Vacuum occurred over multiple weeks during a Texas summer in my 106-year-old house that produces a lot of dust and has multiple high traffic areas with dirt and debris.

My 1,600-square-foot house is a mix of laminate and historic hardwood flooring, making it a great testing space. I ran a variety of cleaning tests with various liquids, barbeque sauce, eggs, flour, coffee, and dried chocolate sauce, making sure to utilize different cleaning modes and taking notes on things like edge cleaning, battery life, and maintenance requirements.
