Dreame H15 Pro vs Roborock F25 Ace vs Tineco S7 Stretch: Which is best for spotless floors? Three brands currently dominate this segment: Roborock, Dreame, and Tineco, each offering their latest generation of wet and dry vacuum cleaners. The Roborock F25 Ace , the Dreame H15 Pro , and the Tineco Floor One S7 Stretch Ultra represent improved versions of the models released the previous year, succeeding the Roborock Flexi Pro, the Dreame H14 Pro, and the Tineco S6 Stretch, respectively.
These three vacuum cleaners/washers incorporate advanced technologies: motorized wheels on some, anti-tangle hair systems, warm water cleaning, and intelligent brush roll drying. The Roborock F25 Ace stands out with the introduction of the SlideTech 2.0 system, featuring independently motorized wheels and a 100-milliliter self-dispensing cleaning solution tank. The Dreame H15 Pro relies on its flexible silicone arm, designed to improve cleaning of the front edges, while the Tineco S7 Stretch boasts impressively large one-liter water tanks. In terms of price, these three models are positioned differently on the European market, with differences of up to 20% between the least expensive and the most expensive. Faced with such a variety of technological offerings, choosing the best vacuum cleaner/washer can be complex for consumers. We tested them; here is our honest opinion based on this test of the Roborock F25 Ace vs. Dreame H15 Pro vs. Tineco S7 Stretch .

Design and ergonomics: three distinct approaches
The Roborock F25 Ace boasts a sleek design with quality materials and a solid build that inspires confidence. The cleaning head stands out with its low profile of 12.5 centimeters, allowing it to easily reach under most low furniture without having to move it. This reduced height is a significant advantage for cleaning hard-to-reach areas such as under sofas, beds, or low sideboards. The handle controls are intuitive, with direct access to the different cleaning modes, allowing you to quickly switch between them without interrupting your cleaning session. The assembly reveals impeccable build quality, with no play or creaking during use, even after several weeks of intensive testing. The buttons are responsive, and the tactile feedback is satisfying. The 100-milliliter automatic solution tank, unique to this model, integrates elegantly without compromising the overall aesthetics. The clean lines and understated color palette blend seamlessly into any modern interior.
Weighing just 4.7 kilograms, it's the lightest of the three, making all maneuvers considerably easier, especially when moving vertically or over obstacles. This lightness is immediately noticeable when lifting the vacuum cleaner to cross a threshold or carry it upstairs. The weight distribution is well thought out, creating a low and centered center of gravity that prevents any feeling of imbalance. The ergonomic handle naturally fits the shape of the hand with a textured, non-slip coating that provides a secure grip even with sweaty hands. The handle's angle reduces wrist fatigue during repetitive back-and-forth movements.
The Dreame H15 Pro takes a bolder approach with its flexible silicone arm integrated into the front of the cleaning head. This mechanism adds visual complexity and alters the traditional proportions of a wet/dry vacuum. The idea behind this arm was to solve the problem of front cleaning by creating a device that automatically descends close to obstacles to sweep dirt towards the brush roll. The materials used are of good quality, and the ergonomic handle offers a comfortable grip for most users. The controls are well-positioned for quick access during cleaning.
However, the flexible arm mechanism on the head prevents the brush roll from fully extending to the side edges, thus reducing the effectiveness of side cleaning compared to the previous model. This limitation represents a regrettable compromise that degrades the traditionally strong performance of wet/dry vacuums. Maintaining this additional mechanism also requires special attention to prevent dirt buildup in the joints. Weighing in at 5.8 kilograms, it is the heaviest of the three models tested. This difference of more than one kilogram compared to the Roborock is clearly noticeable during extended cleaning sessions, especially when lifting the wet/dry vacuum to clean high areas, navigate obstacles, or carry it between floors. Unfortunately, the manufacturer does not provide the clearance height, preventing a precise assessment of its ability to fit under low furniture.
The Tineco S7 Stretch stands out for its generous dimensions, particularly the water tanks, which significantly impact the vacuum cleaner's overall size. This design, with its large one-liter tanks, requires more storage space than its more compact competitors. The finish is meticulous, and the build quality is excellent, with no noticeable weaknesses upon close inspection. The plastic materials used appear robust and capable of withstanding intensive daily use. The cleaning head has a clearance height of 13 centimeters, placing it last among the three models, limiting access under some low furniture such as sofas with short legs or low beds. This difference of a few millimeters may seem insignificant, but it does effectively limit cleaning possibilities.
The absence of motorized wheels on the Tineco results in a simpler design, without the complex drive mechanisms found on the other two models, but requiring more physical effort from the user. Propulsion relies solely on the rotation of the brush roller, which pushes the vacuum forward, creating unidirectional assistance. The transparent tanks allow for easy monitoring of the clean and dirty water levels, a practical detail appreciated daily that prevents the unpleasant surprise of an empty tank mid-cleaning. At approximately 5 kilograms, it falls between the other two in terms of weight, offering an acceptable compromise, although it is closer to the heavier Dreame than the lighter Roborock.
All three vacuum cleaners require a dedicated space for their cleaning and drying station. The Roborock F25 Ace has a compact base that fits easily into a corner of the kitchen, laundry room, or closet. The Dreame H15 Pro includes a heating element to raise the water temperature to 100 degrees Celsius; it's slightly bulkier but still reasonably sized. The Tineco S7 Stretch , with its generous tanks, takes up a little more space. All three models have a magnetic or mechanical locking system to keep the vacuum cleaner stable on its base during automatic cleaning and drying cycles.
The accessibility of the various components for regular maintenance varies between models. The Roborock makes accessing the tanks easy with intuitive push-button release systems that free them in a single action. The brush roller is easily removed for additional manual cleaning if needed, without requiring any tools. The filter is also accessible and quick to replace. The Dreame is slightly more complex with its flexible arm, which requires extra care during cleaning to remove dirt from the joints. The tanks are easy to remove, but the dispensing system can sometimes drip during refilling. The Tineco stands out for its ease of maintenance, with removable components that can be disassembled and reassembled without difficulty. The wide openings of the one-liter tanks facilitate refilling and internal cleaning to remove limescale deposits.
Tank capacity: Tineco in the lead
The Tineco S7 Stretch easily dominates this category with a full one-liter clean water tank, twice the size of its competitors'. This generous capacity theoretically allows for covering larger areas without interruption. The dirty water tank also boasts a one-liter capacity, maintaining a perfect balance between clean and wastewater.
The Roborock F25 Ace features smaller tank capacities but introduces a major innovation: a separate 100-milliliter cleaning solution tank with automatic dispensing. This system offers a real practical advantage in everyday use. The user fills the tank once with a solution that lasts for several weeks, and the vacuum cleaner automatically dispenses the appropriate amount according to the selected mode. This automation ensures a consistently optimal ratio, eliminating manual dosing errors. The mobile app allows users to configure three solution intensity levels: light for daily maintenance, standard for routine cleaning, and intensive for tougher dirt.
The Dreame H15 Pro offers similar capabilities to the Roborock , but lacks a separate solution tank. This omission is all the more surprising given that the previous model, the Dreame H14 Pro , included this very feature. Users must revert to the traditional method of manual dosing with each refill, a repetitive and error-prone process.
In practice, the tank capacity has less of an impact on the user experience than one might think. Standard tanks are more than sufficient to clean an apartment of 60 to 80 square meters before needing to be refilled. Emptying and refilling takes no more than two minutes. The theoretical advantage of the Tineco with its one-liter tanks rarely translates into a significant practical gain for most households.
Cleaning performance and edge cleaning: the Roborock dominates
The Roborock F25 Ace delivers exceptional cleaning results on all tested surfaces, from tiles to hardwood floors. Its powerful suction combined with the optimized brush roll rotation effectively captures all types of debris. Tests with various types of dirt (crumbs, spills, footprints) typically require only one pass to achieve a spotless floor.
The Dreame H15 Pro delivers solid overall performance, but its major innovation—the flexible silicone arm—is problematic. This mechanism automatically lowers itself near obstacles to theoretically sweep away dirt in front of the head. In practice, however, the arm doesn't work reliably, often getting stuck on larger debris like grains of rice. Even more problematic, the addition of this arm has created a bulge that prevents the brush roll from extending to the side edges, significantly degrading edge-cleaning performance.
The fundamental problem lies in the very principle of this innovation. Traditional wet/dry vacuums excel at side cleaning thanks to brush rollers that extend to the edge. To clean a front edge, you simply turn the vacuum 90 degrees and use the side of the brush roller. By adding the flexible arm, Dreame has paradoxically degraded side cleaning performance without actually improving front cleaning. The Dreame H15 Pro thus cleans edges less effectively than its predecessor, the H14 Pro, and its current competitors.
Objective comparative tests confirm this: when a line of rice grains is placed along a wall, the Roborock F25 Ace, used laterally, captures all the grains in a single pass. The Dreame H15 Pro leaves several grains behind, even when approached laterally. The Tineco S7 Stretch achieves intermediate results, acceptable but not reaching the excellence of the Roborock.
The Roborock F25 Ace stands out particularly for its edge-cleaning capabilities, probably the best ever seen on a wet/dry vacuum. The brush roll extends to within millimeters of the edge, drastically reducing dead zones where dust and debris accumulate. Users with pets will especially appreciate this feature, as pet hair and kibble frequently get trapped along walls.
Tests on stubborn stains (dried ketchup, spilled coffee, mud stains) show that the Roborock and Dreame completely remove stains in two or three passes, while the Tineco requires slightly more passes. The Roborock proves particularly effective on grease stains.
Anti-tangling hair: a collective victory
All three models incorporate strategically positioned anti-tangle combs to guide and cut hair before it wraps around the brush roller. This technology proved remarkably effective in all tests, even under deliberately created extreme conditions.
The Roborock F25 Ace , Dreame H15 Pro , and Tineco S7 Stretch all excelled in stress tests with large quantities of deliberately dispersed long hair. No tangling was observed, as the hair was consistently conveyed to the dirty water tank. Post-cleaning inspections revealed no hair wrapped around the brush rollers, confirming the complete effectiveness of the anti-tangling mechanisms.
The tests also included mixed situations combining long hair, pet hair, and debris of varying sizes (crumbs, sand). These heterogeneous conditions more accurately represent everyday life. All three vacuum cleaners handled these situations without difficulty, demonstrating the robustness of their anti-tangling systems. This consistent performance across the three models suggests that the technology has reached a satisfactory level of maturity, finally offering a definitive solution to this previously recurring problem.
Households with pets present a particularly demanding use case. Tests conducted with dog and cat hair demonstrated that the three vacuum cleaners also handle this type of debris very well, validating their use in homes with pets.
Solution distribution and cleaning methods: innovation versus regression
The Roborock F25 Ace stands out with its separate 100-milliliter solution tank with automatic dispensing. This innovation transforms the user experience by eliminating the chore of manual dosing with each refill. The user fills the tank with concentrated solution once, and the vacuum automatically maintains the optimal mixture for several weeks. The app allows you to configure three intensity levels: light for everyday maintenance to conserve solution, standard for general cleaning, and intensive for tougher dirt. This flexibility allows you to precisely tailor the cleaning while optimizing consumption.
The Dreame H15 Pro is a disappointing omission due to the lack of a separate solution reservoir, a feature present on the H14 Pro. This inexplicable regression forces users to revert to repetitive manual dosing with each refill, a tedious and error-prone process. The Tineco S7 Stretch also lacks this feature, maintaining the traditional method.
In terms of cleaning modes, the Tineco S7 Stretch offers an automatic mode that adjusts power according to the detected dirt, a maximum mode for stubborn dirt, a vacuum mode that reduces water usage, and a custom mode configurable in the app. The Roborock F25 Ace offers automatic, maximum, eco, and vacuum modes, with fine-tuning possible in the app.
The Dreame H15 Pro stands out as the only one offering a pure vacuuming mode without any water distribution. This feature theoretically allows the vacuum to be used as a simple stick vacuum. In practice, however, this use remains marginal because wet/dry vacuums are not optimized for this purpose, their performance being inferior to a dedicated stick vacuum.
Motorized wheel system: the revolutionary SlideTech 2.0
The Tineco S7 Stretch is unfortunately notable for its complete lack of motorized wheels, relying solely on the rotation of the brush roll to propel the vacuum forward. This rudimentary system works when pushing, but offers no assistance when pulling backward. The user must exert significant physical force, which is particularly tiring on large surfaces. Transitioning from one floor type to another abruptly increases resistance, requiring additional effort to compensate. This lack of assistance quickly becomes exhausting during extended cleaning sessions.
The Dreame H15 Pro features motorized wheels that assist with bidirectional propulsion (front and rear). This assistance significantly reduces the effort required, creating a light and smooth feel on all surfaces. However, both wheels are driven by a single system without a differential. This limitation occasionally causes slippage during tight turns or angled maneuvers, as one wheel loses traction and creates slight resistance requiring correction.
The Roborock F25 Ace revolutionizes motorized assistance with its SlideTech 2.0 system, introducing independent motors on each wheel. This electronic differential allows each wheel to rotate at a different speed as needed, much like a car's differential. When turning, the outer wheel rotates faster than the inner one, completely eliminating slippage and enabling remarkably smooth changes of direction. The vacuum cleaner seems to glide across the floor with disconcerting ease, requiring minimal effort. This technology likely represents the best implementation of motorized wheels ever seen on a vacuum cleaner.
The system offers three configurable levels of assistance: low for significant manual control, medium for optimal balance, and high for maximum assistance where the vacuum cleaner seems to almost move on its own. This last option will be particularly appealing to the elderly or those with physical limitations.
The impact on the overall experience cannot be underestimated. In direct comparative tests, the superiority of the Roborock F25 Ace is immediately apparent. Its fluid movement transforms a potentially tiring chore into a surprisingly effortless task. The Dreame offers a satisfactory middle ground, while the Tineco remains the most physically demanding.
Autonomy and performance: a similar balance
The Roborock F25 Ace and the Dreame H15 Pro both boast a claimed battery life of 60 minutes in eco mode. In automatic mode (typical use), the actual battery life is around 40-45 minutes. In maximum mode, it drops to 25-30 minutes. The Tineco S7 Stretch offers 50 minutes in eco mode, which is 10 minutes less.
For an apartment of 60-80 square meters, all three have sufficient battery life for a complete cleaning. For homes larger than 100 square meters requiring intensive cleaning, the Tineco might need recharging, whereas the other two would finish on a single charge.
The full charging time is approximately 3-4 hours for all three models. This duration means you should plan your charging, ideally overnight. All three models allow for partial charging without waiting for a complete discharge.
Battery indicators are standard on all three models. The Roborock displays colored LEDs on the handle and a precise percentage in the app. The Dreame features LEDs that change from green to red. The Tineco includes an LCD screen that displays the exact percentage.
The suction power is not communicated in numerical values, but practical tests show similar performance and largely sufficient to effectively capture all types of debris on hard floors (rice, crumbs, sand, hair, fur).
Cleaning and drying the roller brush: Dreame advantage
The Dreame H15 Pro stands out thanks to its use of genuinely hot water during the roller cleaning cycle. A heating element integrated into the base raises the water to 100 degrees Celsius. Boiling water dissolves grease more effectively and offers superior sanitizing properties. Intensive testing with extreme ketchup and coffee stains confirmed that the Dreame appears visually cleaner than those of competitors after the automatic cycle.
The Roborock F25 Ace and the Tineco S7 Stretch take a different approach: they clean the roller with room-temperature water while simultaneously blowing warm air. The Roborock blows air at 90 degrees Celsius, while the Tineco reaches 85 degrees. This hybrid method produces results slightly inferior to hot water cleaning, though still acceptable for normal use.
The difference is explained by the physical properties: water is a significantly more efficient conductor of heat than air, allowing for a more intense heat transfer to the ingrained dirt.
For drying, the Tineco S7 Stretch only offers a 5-minute flash mode at 85 degrees Celsius, which is effective but noisy at 69 decibels. The Dreame H15 Pro theoretically offers two modes (5-minute quick and 30-minute silent), but both generate exactly 52 decibels, suggesting they use the same process. Tests show that the roller is dry after only 10 minutes.
The Roborock F25 Ace offers the most thoughtful solution: a 5-minute quick mode at 66 decibels, and a 30-minute quiet mode at just 47 decibels. This clear distinction allows you to choose according to your priorities. The 47-decibel quiet mode remains very discreet, ideal for undisturbed nighttime drying.
The importance of thorough drying for maintaining hygiene should not be underestimated. A damp roller quickly develops mold, bacteria, and unpleasant odors that will transfer to the floors during the next cleaning.
Price and value for money: Roborock unbeatable
The price analysis reveals significant differences that strongly influence the final recommendation. The Tineco S7 Stretch and the Dreame H15 Pro are priced identically in the upper range of the premium segment on the European market.
The Roborock F25 Ace shakes things up with a price more than 20% lower than its competitors. This substantial difference represents savings of several tens of euros. Current promotions widen the gap even further. For a product that objectively dominates in almost every technical category, simultaneously offering the lowest price is a remarkably aggressive marketing strategy.
Beyond the initial purchase price, recurring costs deserve consideration. All three require the regular purchase of cleaning solution. The Roborock has an advantage with its optimal automatic dosing, avoiding the frequent waste associated with approximate manual dosing.
Replacement parts (brush rollers, filters) represent another cost. Prices vary depending on the manufacturer but are generally within a similar range. Roborock offers bundled accessory packs at competitive prices.
All three brands offer standard two-year warranties in accordance with European regulations. Roborock has a well-established after-sales service network in Europe, a legacy of its success with robot vacuum cleaners. Dreame has a decent infrastructure that is still under development. Tineco, a newer brand, has a network that is still being built.
The fundamental question of value for money boils down to this: which product offers the best performance package for the price? The Roborock F25 Ace clearly dominates this assessment. Not only does it outperform its competitors in almost every technical category (edge cleaning, motorized wheels with differential, automatic solution tank, reduced weight, flexible drying options), but it does so at a significantly lower price. This rare combination of technical superiority and price advantage makes it an obvious recommendation.
The Dreame H15 Pro finds itself in a difficult position: offering a product that is objectively less efficient (flawed flexible arm, no automatic water tank) while being the most expensive and heaviest. The Tineco S7 Stretch suffers primarily from its lack of fully motorized wheels, which severely limits its ease of use.

Final verdict
After extensive testing, the Roborock F25 Ace stands out as the clear choice among this trio. Objectively dominating in almost every category, it represents the optimal balance between technical performance and user experience. The SlideTech 2.0 system revolutionizes ease of use, transforming a potentially tiring chore into a surprisingly easy task. The automatic cleaning solution tank eliminates repetitive manual dosing. Edge cleaning performance reaches a level of excellence rarely seen.
Roborock F25 Ace 's key strengths include its lightweight design (4.7 kilograms) for easy handling, its low clearance height (12.5 centimeters), its smart drying options (fast or quiet), its generous 60-minute runtime, its well-designed app, its robust construction, and above all, its price, which is more than 20% lower than the competition. This offer is simply unbeatable.
The weaknesses remain minor: the roller cleaning uses hot air rather than hot water (slightly less effective), the absence of a pure suction mode (marginal functionality), and the absence of an LED headlight (a limitation shared by all).
The Dreame H15 Pro comes in second place despite its high price. Its main advantage lies in its 100-degree hot water cleaning system for the roller, offering superior removal of ingrained dirt. Unfortunately, the innovative flexible arm proves to be a failure, compromising lateral performance. The lack of an automatic cleaning solution tank is an inexplicable step backward. Its weight of 5.8 kilograms negatively impacts user comfort.
The Tineco S7 Stretch comes in third place primarily due to its fatal lack of fully motorized wheels, making for a physically demanding experience. The large tanks are a theoretical advantage that is rarely practical. The 50-minute runtime limits the area that can be covered. The single drying cycle generates 69 decibels, a potentially bothersome high noise level.
Final score: Roborock F25 Ace 9/10 – Dreame H15 Pro 7/10 – Tineco S7 Stretch 6.5/10
Purchase recommendation: The Roborock F25 Ace is the optimal choice for almost all users. Its superior technology combined with its competitive price makes it the obvious choice. The Dreame H15 Pro can only be recommended for those who absolutely require hot water cleaning of the roller, despite the compromises. The Tineco S7 Stretch is only suitable for users with very large areas requiring maximum tank capacity and who are willing to accept the absence of motorized wheels.
Alternatives to consider: The Roborock Flexi Pro offers excellent performance at a lower price. The Tineco Floor One S5 offers maximum compactness. The Bissell CrossWave HydroSteam incorporates a new generation of steam for deep cleaning. The Dreame H12 Pro , without the problematic flexible arm but with an automatic dustbin, is a better buy than the H15 Pro.
