Tineco presents the Floor One S7 Stretch Ultra, a floor mop positioned in the premium segment at €429. This model incorporates the technologies developed by the manufacturer in recent years: a 180° flat tilt, a Flash Dry system for hot air drying, a 230-watt motor integrated into the roller, and a battery offering a claimed 50 minutes of runtime. This vacuum cleaner and mop targets users looking for a versatile appliance capable of vacuuming and washing simultaneously without manual intervention between cycles.
Compared to the Tineco Floor One S7 Pro, this Ultra version boasts 10 watts of motor power, 10 minutes of runtime, and a 200 ml larger clean water tank. The weight increases by 2 kg, reaching 7 kg, but this is offset by a different weight distribution. We tested the device for several weeks on various surfaces and types of dirt to assess its real-world performance against the manufacturer's claims. While the runtime and cleaning efficiency are impressive, a few design details could be improved. Here is our full review.

Design and ergonomics: 7 kg that you forget you're even wearing.
From the moment you open the box of the Tineco One S7 Stretch Ultra, the attention to design is immediately apparent. Tineco is probably one of the few brands, if not the only one, that truly strives to create a premium design for this type of vacuum cleaner. Where most floor-standing vacuums resemble purely utilitarian tools, this one boasts clean lines that stand out sharply from the competition. Lifting the Tineco Floor One S7 Stretch Ultra for the first time, you can definitely feel its advertised 7 kg weight. That's 2 kg more than previous generations, an extra weight resulting from the larger battery and the increased 1-liter clean water tank.
The packaging reveals a complete set of accessories: several extra rollers, replacement filters, and even samples of specific detergent. The brand recommends using its own products, although there are likely other compatible options available. A closer look at the design quickly reveals the trick to offsetting the extra weight: the clean water tank is located at the very bottom of the machine. This design significantly lowers the center of gravity. As a result, when you grasp the handle to maneuver the machine, it remains surprisingly light. The weight is elsewhere, away from your hands.
From the very first meters of cleaning with the One S7 Stretch Ultra , you immediately notice how the motorized roller naturally propels the vacuum cleaner forward. You simply guide it, without really pushing it. Only the reverse movement requires a slight pull to bring the mop back towards you, but nothing cumbersome even after 30 minutes of continuous use. This automatic drive system isn't entirely new and is starting to become more common on the market, but it remains just as effective.
By removing the One S7 Stretch Ultra's clean water tank to check its actual capacity, we filled a measuring cup: exactly 1 liter. Some manufacturers tend to inflate these figures, but that's not the case here. As for the collection bin, its capacity reaches 800 milliliters, which makes sense since the amount of water dispensed is greater than the amount of dirty water collected by the vacuum. This difference in volume partially determines the device's overall battery life.
Opening the collection compartment reveals its particularly ingenious design. A grid with 2 mm gaps physically separates two distinct zones. Debris and particles larger than 2 mm remain in the upper compartment, while dirty water collects in the lower section. This separation greatly simplifies cleaning: the solid waste goes directly into the bin, while the liquid is poured down the sink or toilet. This separation completely transforms the emptying experience, eliminating the need to handle a foul-smelling mixture. A HEPA filter tops the entire system.
It also features an edge-to-edge rotating roller. Specifically, the One S7 Stretch Ultra can clean along baseboards to within 2 to 3 mm on the left side and approximately 5 mm on the right. One of the key features of this model is the integration of the motor directly inside the rotating roller. This is one of the characteristics that distinguishes high-end models from entry-level and mid-range models, which are generally equipped with an off-center motor driven by a belt.
By tilting the Floor One S7 Stretch Ultra forward, it unfolds to form an almost perfectly flat line. This ability to tilt fully 180° from the floor is one of its key features. At just 13 cm high in this position, it's the slimmest model available on the market. A tape measure confirms this measurement. The device easily slides under beds, sofas, and low sideboards.
However, one detail deserved more attention: the absence of a front wheel. A small wheel would have allowed for smooth movement across the floor without scratching the underside of the device. Tineco has, however, integrated a rubber pad that prevents the chassis from directly touching the floor. This rubber pad adequately fulfills its protective function but creates slight resistance when moving the device in a horizontal position.
A major advantage: when the stick vacuum cleaner is lying flat, the area containing solid waste remains perfectly sealed off from the liquid area. This is doubly beneficial: the two types of dirt don't mix, and most importantly, nothing can leak from the vacuum cleaner while maneuvering under furniture.
One S7 Stretch Ultra performance: intensive and revealing tests
The technical aspects of the Tineco S7 Stretch Ultra rely on a sophisticated system. The roller incorporates a small rake that forms the anti-tangle system. Teeth and a metal strip continuously scrape the brush to remove hair and pet fur. The operating principle is simple: the brush remains constantly moistened and rotates at 450 revolutions per minute upon contact with the floor. Dirt is then collected by the 230-watt suction power, the highest currently available in the Tineco range. This power represents a 10-watt increase compared to the S7 Pro, which delivers 220 watts.
To assess the true capabilities of the Tineco Floor One S7 Stretch Ultra , we deliberately recreated extreme scenarios. On the living room tiles, we combined an unusual mixture: sand, sugar, salt, wood shavings, crushed glass, and plastic—something never encountered in normal use. These are the same types of dirt we typically use for all our tests. This first test promises to be particularly challenging: no one will ever encounter so much dirt in one place in their daily life, but the exercise allows us to verify maximum performance, especially the separation between liquids and dry dirt.
When you turn on the Tineco cordless vacuum cleaner , the color screen on the handle lights up. It takes about 5 seconds for the mop to become fully wet and the device ready for use. Going directly over a pile of dirt, the Tineco One S7 Stretch Ultra removes a good portion of it on the first pass. A small trace remains in the center. One pass back and forth is all it takes to get the floor perfectly clean again. To illustrate the performance: a conventional stick vacuum would pick up this dirt in a single pass, while a mop-and-sweep requires only one pass, which is a very good performance, especially since these devices are not fundamentally designed to pick up so much dry dirt at once.
After disassembling the One S7 Stretch Ultra's dustbin after this test, we observed that the now-moistened dirt was indeed mostly concentrated in the upper compartment. A few particles did end up in the water at the bottom, but this is unavoidable and normal: the holes in the separation grid are spaced approximately 2 mm apart, meaning they only retain particles larger than this size.
The next test is more challenging: human hair and pet fur. We collected a significant amount of long hair on a brush, to which we added dog hair. The vacuum cleaner's ability to remove it from the floor is undeniable. The real test lies in checking the condition of the rotating brush after this process. To create a visual contrast, we deposited these fibers on a carpet, even though these vacuums are not designed for use on this type of surface.
The result is remarkable: after use, not a single pet hair or human hair appears on the rotating brush. Everything has been scraped away by the anti-tangle system. Even in the narrower areas where fibers might have become trapped, a thorough inspection reveals absolutely nothing.
Let's move on to the edge-cleaning test. We placed a line of sugar along a baseboard and ran the vacuum in its normal position. The edge-to-edge roller barely touched the wall, leaving only 2 to 3 mm of space. One pass, and all the sugar was gone without a trace. These tests demonstrate that, even with heavy daily use, the vacuum cleaner manages to leave the floor perfectly clean.
Having tested dry dirt, let's now tackle wet dirt. Our first test is with a classic, especially useful for its visual contrast: Coca-Cola. This type of liquid is extremely easy for this kind of vacuum cleaner to handle. We pour a generous amount to create a nice puddle. By passing directly through it at medium speed, the device manages to collect everything in one pass. One or two passes to perfect the job, and the result is impeccable.
The next test is no joke. Let's move on to the egg. Regarding the broken egg, the liquid part poses no problem. The device sucks it up without difficulty. It's the solid part, the shell, that's the issue. The vacuum cleaner does leave some of it on the floor, which isn't really a big deal. The important thing is that the egg itself has been picked up. The shells will have to be collected by hand. This limitation is normal since this type of device isn't designed to vacuum up such large and rigid debris.
We're now getting out our stash of expired yogurt to test its grease-like properties. We spread it on the tiles, varying the thickness. Given the product's thickness, we spread it lightly while still maintaining a good layer. This test should be relatively easy. And indeed, with this thickness, one coat is enough. We still go over it again just to be safe, but the first coat has already done most of the work.
The final test of the Tineco Floor One S7 Stretch Ultra is by far the most challenging. It involves getting the vacuum cleaner to absorb ketchup, but especially soy sauce. Soy sauce stains are a real challenge, and we're not going to skimp on the amount. This test will primarily assess the self-cleaning capabilities of the vacuum and its rotating brush.
Ketchup is no problem. One pass and it's done. Soy sauce is a little trickier: a small brown stain might remain after the first pass. One or two passes and it disappears easily. The efficiency seems superior to previous generations. There must have been improvements in this area.
But the real challenge lies in the state of the rotating brush after this test. It inevitably takes on the color of soy sauce and ketchup. A delightful mixture of the two appears, mainly in the center and slightly on the right side. This is when the self-cleaning function will demonstrate its effectiveness.
One detail worth highlighting regarding the water injection system is that the water is injected from inside the roller, not from above. This method ensures better water distribution across the entire width of the brush. The automatic mode, activated by default, constantly adjusts the flow rate according to the detected level of soiling. On heavily soiled surfaces, water consumption increases significantly. During a test on a particularly dirty living room, the tank emptied in just 15 minutes, as the device detected the need to drastically increase water output. On other, normally soiled surfaces, consumption remained very moderate. After 30 minutes of cleaning, the tank still retained nearly half its capacity.
Our final test with the One S7 Stretch Ultra, although not recommended by the manufacturer, involved using the Tineco vacuum cleaner and on a short-pile carpet. The results were conclusive for surface dirt. The damp roller effectively loosened dust and light debris. However, it's advisable to limit the number of passes to avoid excessive wetting of the carpet, as the device isn't designed to dry the fibers.
Interface and connectivity: a color screen and a full application
The Floor One S7 Stretch Ultra cordless vacuum cleaner features a color display on the handle , showing the remaining battery life, power level (adjustable or in automatic mode with dirt detection), and various status indicators. All functions can be controlled via two physical buttons: a power button and a power adjustment button.
This screen provides all the necessary information. Its quality is impressive. Displayed in color, it shows the auto mode, maximum mode, and session mode for vacuuming. All the useful information is clearly displayed. This type of interface remains quite rare in this product category.
The last button, located above the handle, starts the self-cleaning function. A small Wi-Fi button on the back allows you to connect the device. The Tineco app, available on the Android and Apple stores, is easy to find. Once downloaded, account creation takes only a few seconds, with remarkable simplicity. Activating Bluetooth then connects the vacuum cleaner. On the back of the device, a button requires a three-second press to activate Wi-Fi. Connecting to the app takes approximately two or three seconds.
The options available in the app are quite comprehensive. It's possible to modify certain modes (except for the automatic mode), increase the suction power, adjust the water temperature, and choose how the water is projected: as a light mist or a more intense spray. This last feature is particularly useful. Another very practical aspect is the language selection. The device is set to English by default and makes voice announcements in that language upon startup, but it can be switched to French via the app.
Another notable feature of the Floor One S7 Stretch Ultra is its cleaning tracking. Surprisingly, the app records the number of square meters cleaned, the usage time, and maintains a complete history. This tracking, comparable to a health app, adds a fun element to the experience. This level of detail far surpasses what competitors typically offer in this price range.
Battery life: 50 minutes advertised, 48 minutes measured
Tineco announces 50 minutes of battery life for the Floor One S7 Stretch Ultra, 10 minutes more than the previous generation. An ambitious promise that we wanted to verify in real-world conditions, by cleaning a 250 m² home.
The protocol is simple: start with a full battery, automatic mode activated (the one most users will choose by default), and a complete, uninterrupted cleaning of the house. The vacuum cleaner begins in a large living room of nearly 100 m², then moves to a dining room of similar size, then a kitchen of approximately 50 m², before finishing with the remaining rooms.
The experience during the test
From the very first minutes, you appreciate the lightness of the Tineco One S7 Stretch Ultra: the weight is concentrated on the motorized base, so the handle remains very maneuverable. The Tineco stick vacuum practically moves forward on its own thanks to the rotating brush drive. The only effort required is pulling it back when reversing, which demands no particular strength. While some competitors now offer motorized wheels to make this maneuver even easier, the Tineco's system remains comfortable for everyday use.
The screen displays the remaining battery life in real time. During cleaning, several power spikes are observed: the device detects dirtier areas and automatically adjusts its performance. The minutes tick by: 10, 20, 30, 40… At exactly 48 minutes, the screen displays a critical battery level, and the device gradually slows down before shutting down completely.
48 minutes confirmed, a record in the category
The result is clear: 48 minutes of actual battery life in automatic mode, just 2 minutes less than the manufacturer's claim. This is simply a record among all the floor scrubbers we've tested so far. Most competitors top out at between 30 and 40 minutes maximum.
Adaptive water consumption
During the Tneco Floor One S7 Stretch Ultra test, one detail revealed the system's intelligence: we only had to refill the clean water tank one and a half times. The first refill occurred after just 15 minutes, the time it took to clean the large living room. The device had detected a high level of dirt and automatically increased the water flow to improve cleaning efficiency. As a result, the 1-liter tank emptied quickly, and the dirty water tank filled just as fast.
However, on the rest of the surface, consumption stabilized: after 30 minutes of cleaning in normal mode, approximately 40% of the clean water remained in the tank. It can therefore be reasonably stated that on a moderately soiled surface, a single 1-liter tank is sufficient to last the 50 minutes advertised by Tineco.
Maneuverability and everyday use
Despite its 7 kg weight, the One S7 Stretch Ultra is surprisingly easy to handle from the very first minutes of use. The low positioning of the water tank and the lightness of the handle completely transform the perception. There's no feeling of heaviness, even after 30 minutes of continuous cleaning on large surfaces.
Changes of direction are made without noticeable resistance. The device pivots easily, making it easy to maneuver around obstacles and clean around furniture legs. This agility proves particularly useful in cluttered spaces.
An interesting phenomenon occurs when using a good quality detergent. When left on the tiles for a few moments, it completely removes the stains. In particular, it eliminates the large black marks that become embedded in porous and relatively light-colored tiles. The effect is striking. The line between the area treated with the detergent and the untreated area is clearly visible.
The ability to go under furniture is also incredibly practical. Of course, it all depends on the furniture's clearance. As long as it's more than 13 cm high, the vacuum cleaner can easily go underneath. This feature is a real game-changer, especially for cleaning under beds.
Although the manufacturers don't recommend it, we also tested the Tineco Floor One S7 Stretch Ultra vacuum cleaner on carpets, using light pressure. For surface dirt, the vacuum demonstrates a real ability to dislodge it. On a particularly dirty carpet, a quick pass provided a noticeable refresh. However, it's best not to go over the same area repeatedly to avoid excessive wetting.
Positioning of the One S7 Stretch Ultra and alternatives
The One S7 Stretch Ultra is more of an evolution than a revolution. This model combines all the qualities of previous generations with the brand's recent innovations. These include Flash Dry for self-cleaning and hot air drying, as well as the ability to tilt up to 180 degrees, a feature that is becoming almost essential in this segment. This last feature was already present on the Tineco Floor One S6 Stretch Ultra.
This stick vacuum cleaner excels in terms of battery life thanks to its high-performance battery. It also stands out for its dirt detection system, which automatically activates features that increase suction power and water flow when needed. In fact, it picked up everything we asked of it: hair and pet hair were effectively removed with the rotating brush, baseboards were cleaned, and the floors were left spotless overall.
We did not test stains that had been embedded in the floor for several days, simply because we did not have any available in our home at the time of the test.
There's not much to criticize about this appliance. The addition of a small wheel for use on a flat surface would have been a welcome feature, but the small rubber pad on the top effectively prevents scratches. We didn't find any major innovations inside. It's more of a showcase of the best technologies developed by Tineco, making it the most advanced model currently available.
This positioning, however, doesn't knock out previous generations, nor even the other S7 versions available at a lower price. Some of the technologies present on the S7 Stretch Ultra may not be essential for all uses.
According to available information, an S9 model is expected to be released soon. It will reportedly incorporate the much-anticipated motorized steering wheels, currently lacking in the existing model, which could be a significant improvement. The product sheet also suggests, although this remains to be confirmed, that it will have the ability to dry the floor simultaneously with the washing process. This feature would reduce humidity in the air, which could be an additional benefit.
Even the Tineco Floor One Stretch S6 isn't outdated or superseded by this generation, which is more refined in certain aspects. The S6 remains available at a lower price, as do the other S7 models tested previously. Users therefore have a wide range of choices to suit their budget and needs.
The price of 429 euros positions the Tineco Floor One S7 Stretch Ultra in the premium segment. This amount may seem high, but it is justified by its record-breaking 50-minute battery life (compared to the competition's 30-40 minutes), its 230-watt power output (versus the usual 180-200 watts), the Flash Dry system which actually dries the roller, and above-average build quality.

What is the actual battery life of the Tineco Floor One S7 Stretch Ultra?
We measured 48 minutes of effective battery life in automatic mode on a 250 m² surface. Tineco advertises 50 minutes, so the 2-minute difference is negligible. This is currently a record in the sweeper mop category.
How long did the battery life last on older models?
Previous generations (like the S7 Pro) offered 40 minutes of battery life . The S7 Stretch Ultra therefore gains an additional 10 minutes, representing a 25% increase in battery life.
Does battery life vary depending on the mode?
Yes. Our test was conducted in automatic mode , which adjusts the power according to the detected level of dirt. In minimum mode, the battery life can reach a full 50 minutes. In maximum mode (constant power), it will logically be reduced.
How many times should the water tank be refilled in 48 minutes?
It depends on the level of dirt. On a very dirty surface, we had to refill the 1-liter tank one and a half times in 48 minutes. On a normally dirty surface, a single tank is enough to last the entire runtime.
Why does the Tineco one S7 Stretch Ultra consume more water in certain areas?
The iLoop sensor automatically detects the level of dirt and increases the water flow in dirtier areas . During our test, the heavily soiled living room emptied the tank in 15 minutes, while the rest of the house used significantly less water.
Is the S7 Stretch Ultra difficult to handle for 48 minutes?
No, the device remains light and easy to maneuver throughout the cleaning process. The weight is concentrated on the motorized base, and the handle is lightweight. The rotating brush propels the device forward; you simply pull it back, requiring no particular effort.
Verdict: the long-awaited concentration of excellence – Tineco Floor One S7 Stretch Ultra
the Tineco One S7 Stretch Ultra are clear. The device has demonstrated its capabilities on all types of dirt tested: liquids, dust, and debris on the floor. Drying, self-cleaning, and roller drying have also proven their effectiveness. Battery life is also impressive.
measured 48-50 minute runtime is an absolute record , allowing for uninterrupted cleaning of very large areas. The combination of 230 watts 21 kPa of pressure ensures impressive efficiency. The Flash Dry works as advertised, completely drying the roller in 5 minutes and eliminating any risk of odors.
The 180° tilt and 13 cm height transform everyday use by making it easier to access items under furniture. The color screen and app enhance the experience without complicating it. Intelligent separation between solid and liquid waste significantly simplifies cleaning.
Regarding the drawbacks, we identified one main one: the absence of a small wheel on the body for maneuvering under furniture at 180°. The current small rubber wheel rubs slightly and creates resistance, hindering ease of use.
Otherwise, the device has all the right features: telescopic design, edge-to-edge roller ultra-powerful suction . The self-cleaning function is a real treat: the roller comes out clean, without any lingering color or odor . This system truly solves the problem of unpleasant smells that develop over time in wet/dry vacuums.
This mop is designed for owners of large areas exceeding 100 m² , households with pets that generate a lot of hair and fur, and users concerned about hygiene. The price of 429 euros makes it suitable for those with a higher initial investment.
Final score: 8.5/10. The Tineco Floor One S7 Stretch Ultra receives a score of 8.5/10, reflecting its excellent performance tempered by a high price point. It loses half a point for the lack of front wheels and a full point for its price. Users looking for the best floor mop without budget constraints will find this a model that is hard to beat.
A concentration of all the best technologies on the market in a single device. With record-breaking battery life and ultra-fast roller drying, the Tineco S7 Stretch Ultra is the best current mop for large areas and demanding users, despite its price and the absence of a small wheel for optimal comfort under furniture.
