Tineco Floor One S9 Artist Steam vs Tineco Floor One S7 Stretch Ultra
Quick take: The Tineco Floor One S7 Stretch Ultra costs $150 less; the Tineco Floor One S9 Artist Steam has stronger suction (22,000 vs 21,000 Pa); the Tineco Floor One S9 Artist Steam runs longer per charge (75 vs 50 min).
Which one to buy
Steam is the only reason to pay $300 more. The S9 Artist Steam adds a 320°F HyperSteam system for dried-on grease and set-in stains, and its owners point to independent lab testing that tied it for the best stain-removal result among hard floor cleaners. Otherwise the S7 Stretch Ultra covers the same ground: a 180-degree lay-flat body that slides under beds and sofas, a FlashDry dock that hot-washes the roller, and an iLoop sensor that ramps suction and water on dirtier patches.
The S9 also runs longer, rated at 75 minutes against 50, and owners say it leaves floors noticeably drier after a pass. Its costs show up elsewhere. Owners put it at about 13.5 pounds, heavier than the S7's 11.5, which you feel carrying it upstairs even with self-propulsion. Its 880 ml clean tank is smaller than the S7's 1 L, so expect more refill stops on a large floor despite the long runtime, and steam mode needs 45 to 60 seconds to heat before each pass. The S7 is rated at 78 dB, on the louder side for the category.
Both are hard-floor only, and both still need the dirty tank rinsed after every session. If your floors are maintenance-level dirty, the S7 delivers the same lay-flat reach and self-drying dock with a bigger tank for $449, and it's the better buy. The S9 earns its price in kitchens and pet homes where grease and set-in stains survive an ordinary wet pass.
Tineco Floor One S9 Artist Steam
Worth the extra $300 where cooking grease, pet accidents or set-in stains survive a normal wet pass and you want steam to lift them.
Tineco Floor One S7 Stretch Ultra
For everyday mopping, the better value: the same lay-flat reach and self-drying dock with a 1 L tank and a lighter body.
