The catch
Tineco FLOOR ONE S7 Stretch Steam
Some sealed floors cannot take steam
Side by side
Tineco S7 Stretch Steam vs S9 Artist Steam: S9 brings maneuvering help, yet both hold the same clean-water volume
Quick verdict
Go with the S9 Artist Steam for its powered maneuvering, three-sided edge cleaning and explicit 30-minute Steam rating. Cordless steam and lie-flat washing are already part of S7 Stretch Steam. With an 880 ml clean tank on both, moving up does not mean fewer refills through tank size alone.
Before you buy
Why, and what it costs you
A newer model does not mean a bigger clean tank
The reservoir is 880 ml on both. If stopping to refill is what bothers you, S9 won't fix that with reservoir size. Powered maneuvering and edge access are its stronger reasons to buy.
Where this comes from
Matching published clean capacity makes for a direct comparison. Flow rates can differ, though, so equal capacity doesn't prove equal time between refills.

Differences you will notice
A newer model does not mean a bigger clean tank
The reservoir is 880 ml on both. If stopping to refill is what bothers you, S9 won't fix that with reservoir size. Powered maneuvering and edge access are its stronger reasons to buy.
How we worked this out
Matching published clean capacity makes for a direct comparison. Flow rates can differ, though, so equal capacity doesn't prove equal time between refills.
Plan an S9 steam session around 30 minutes
The S9's 75-minute maximum is for lie-flat Auto washing, while Steam is rated up to 30 minutes. If you plan to steam several rooms, that gap matters, even though one machine runs both modes.
How we worked this out
The two manufacturer maxima differ by 75 − 30 = 45 minutes. No equivalent mode-specific S7 runtime is used, since the reviewed sources conflict.
Front-edge reach helps most in dead ends
The S9's third cleaning side helps at a cabinet plinth or wall where turning the head is awkward. Along an open straight wall, a two-sided head can already come at it from either direction, so the extra side matters less in the decision.
How we worked this out
The conclusion rests on two-sided versus three-sided edge geometry. No measured difference in the width of dirt left behind is claimed.

Decision guide
How to decide
The S9 Artist Steam wins on powered maneuvering, three-sided edge cleaning and an explicit 30-minute Steam rating. S7 Stretch Steam already offers cordless steam and lie-flat washing. Because the clean tank is 880 ml on both, the upgrade does not cut refills on tank size alone.
A newer model does not mean a bigger clean tank
Each uses 880 ml. When stopping to refill is your gripe, the S9 does not fix it with a larger reservoir. Powered maneuvering and edge access are better reasons to buy it. Published clean capacities are equal, which makes this a direct comparison. Flow rates may differ though, so equal capacity does not show equal time between refills.
Plan an S9 steam session around 30 minutes
The 75-minute maximum on the S9 is for lie-flat Auto washing, whereas Steam is rated for up to 30 minutes. If you plan to steam several rooms, that difference matters, even though one machine runs both modes. 75 − 30 = 45 minutes separates the two manufacturer maxima. No comparable mode-specific runtime is used for the S7 because the reviewed sources conflict.
Front-edge reach helps most in dead ends
Where turning the head is awkward, such as at a cabinet plinth or a wall, the S9’s third cleaning side helps. Along an open straight wall a two-sided head can come at it from either direction already, so the extra side weighs less in the decision. The conclusion comes from comparing two-sided and three-sided edge geometry. No measured difference in the width of dirt left behind is claimed.
What this page can’t tell you
- Documented designs and operating limits are the basis here. No ranking is given for measured pickup, noise, sanitizing performance or pet comfort. Solid pet waste needs separate removal, and the floor and machine care instructions still apply.
