Differences that may change your choice
These are published weights, not measurements in a common configuration. Tineco’s FAQ specifies empty weight; Roborock distinguishes the appliance from packaging without a comparable protocol. Runtimes also use different modes and conditions.
| Criterion | Tineco FLOOR ONE STRETCH S6 | Roborock F25 XT |
|---|---|---|
| Lay-flat body | 13 cm | 12.5 cm |
| Published mass | 4.5 kg; FAQ: empty | 4.7 kg appliance, not 8.3 kg parcel |
| Documented runtime | 25–40 min in manual | Up to 60 min in Eco mode |
| Clean water | Approx. 800 ml | 740 ml, ACE/XT specification |
| Dirty-water tank | Approx. 720 ml in manual; 700 ml in store | 720 ml, ACE/XT specification |
| Features to investigate | Lay-flat setup and FlashDry maintenance | SlideTech 2.0 wheels and automatic solution dosing |
Consider Tineco first when lifting matters
If you clean several floors, cross steps or store the cleaner elsewhere, STRETCH S6’s published weight warrants a first look. The stated difference from Roborock is 200 g, insufficient to prove a noticeable difference in your hand. Check grip, balance and tank removal too.
If both fit under furniture and manual dosing is easy for you, F25 XT’s extras may solve no real constraint. Any premium then needs a specific use, not simply a longer feature list.
Consider Roborock when its features solve a problem
The documented SlideTech 2.0 wheels and automatic solution dispenser are concrete reasons to shortlist F25 XT for steering and refill organisation. They do not lighten carrying upstairs or demonstrate better stain removal.
Between 12.5 and 13 cm of clearance, XT alone may have a positive theoretical margin, provided the gap exceeds 12.5 cm. Five millimetres can affect a shortlist but do not guarantee passage under a crossbar or room to manoeuvre.
Do not turn 60 versus 40 minutes into a verdict
Tineco’s manual gives 25–40 minutes; Roborock’s 60-minute maximum is Eco mode. Without a common route, dirt level and settings, these figures cannot show that XT cleans 50% more floor in your home.
For long sessions, record your existing cleaning time and pauses to move objects. Allow a runtime margin and charging access. Tineco’s additional 60 ml of stated clean water cannot predict a number of rooms either: water flow and mode matter.
Four checks before ordering
Roborock’s French page retains ACE/ALT in the address but currently presents F25 XT as a cosmetic ACE evolution. That does not authorise silently substituting an ACE offer. Likewise, keep FLOOR ONE STRETCH S6, FLOOR ONE S6 and SWITCH S6 STRETCH separate.
Dock maintenance does not replace tank care. Roller washing and drying temperatures are not the temperatures applied to your flooring.
- Exclude both if your flooring instructions prohibit this wet-cleaning method.
- Do not order for a gap equal to or lower than the body height.
- Check exact name, accessories and seller in the chosen offer.
- Identify compatible roller and filter references before valuing a bundle.
For Black Friday, set the premium you will accept
Keep baskets comparable: exact model, delivered price and genuinely useful accessories. If both meet your needs, use the calculator to test consumable assumptions. Do not assign automatic dosing a detergent saving without evidence.
Decide which constraint a feature solves, then set your maximum premium for that difference. A large crossed-out price alone does not establish a better offer than yesterday’s.
Practical answers
Frequently asked questions
Will F25 XT fit beneath a 13 cm gap?
Its stated lay-flat height is 12.5 cm, leaving a theoretical 5 mm. Check the lowest point and obstacles throughout the depth; this is not a fit guarantee.
Is STRETCH S6 preferable for stairs?
Its published 4.5 kg weight warrants checking it first for carrying. That does not validate ergonomics on your stairs: check grip and transport instructions.
Does Roborock have 50% more real runtime?
That is not established. Its 60-minute Eco maximum and Tineco’s 25–40-minute range use different conditions.
Does automatic dosing save detergent?
No comparative saving has been measured here. The documented feature is automatic dosing, not guaranteed annual savings.
Can an F25 ACE offer replace XT in this comparison?
Not automatically. Even if the manufacturer connects their features, the offer must match the model you intend to buy.
