Main Differences That Matter
Roborock gives you more cleaning modes
The biggest difference is not suction—it is cleaning versatility. F25 Ultra Steam combines steam with a separate hot-water cleaning mode and automatic solution mixing, making it better suited to greasy kitchen residue and stubborn sticky messes.
Tineco gives you longer regular runtime
S7 Stretch Steam is the better choice for large hard-floor areas when you want to stay in standard cleaning modes for longer. Its up-to-75-minute runtime is one of its strongest practical advantages.
Both are designed for under-furniture cleaning
Both recline low enough to clean under beds and furniture. Tineco’s 180° Stretch design is a central part of the S7’s appeal, while Roborock also emphasizes low-profile cleaning with assisted movement.
Best Overall: Roborock F25 Ultra Steam
Roborock F25 Ultra Steam

Large clean-water tank
Strong suction

Tineco FLOOR ONE S7 Stretch Steam
Best for Long Steam-Cleaning Sessions
S7 Stretch Steam remains a strong purchase because it combines 320°F HyperSteam, 180° lay-flat cleaning, anti-tangle design, FlashDry maintenance, and up to 75 minutes of runtime in a model that sits below Tineco’s newer S9 steam flagship.
Pros
Long regular runtime
Strong steam cleaning
180° lay-flat design
FlashDry maintenance
Good Tineco value
Cons
No separate hot-water cleaning mode
Less feature-rich than Roborock
S9 Artist Steam Pro is the newer Tineco steam flagship
Should You Still Buy the S7 Stretch Steam?
Yes—if value matters. The S9 Artist Steam Pro is the newer and more premium Tineco steam model, but the S7 Stretch Steam still covers the core reasons most people buy a steam floor washer: high-temperature steam, long runtime, lay-flat reach, anti-tangle cleaning, and heated self-maintenance.
Move up to the S9 Artist Steam Pro if you specifically want Tineco’s latest premium steam platform and are willing to pay more for it.
Should You Still Buy the F25 Ultra Steam?
Yes if you need a machine now and want Roborock’s strongest current steam-and-hot-water cleaning system. The upcoming Gen 2 is more interesting for buyers who can wait and want longer runtime plus the latest edge-cleaning hardware.
What About Tineco S9 Master?
Tineco S9 Master is another newer option, but it is better understood as a hot-water floor washer rather than a direct steam replacement. It makes more sense if you want 23kPa suction, ThermoBlast hot-water mopping, a slim chassis, and FlashDry but do not specifically need steam.
