Head-to-head
Dreame H15 Pro Heat vs Tineco S9 Artist Steam: Hot-water washing and steam need different floor-care permission
The short answer
Choose H15 Pro Heat for heated water washing and its front-reaching edge arm. Choose S9 Artist Steam when your floor specifically permits steam and you want the longer stated heated-mode window. Check the floor care rules first, because hot water and steam are different treatments.
Before you choose
The reasoning and the trade-offs
The heating method comes before the temperature number
Steam and heated-water washing expose a floor to moisture and heat differently. A steam-prohibited floor does not become suitable because the machine also has an ordinary washing mode. Buy for the treatment your floor actually permits.
What this is based on
Manufacturer descriptions establish different heating methods. Their heater and dock temperature figures are not comparable measurements at the floor surface.

What matters in practice
The differences that matter
The heating method comes before the temperature number
Steam and heated-water washing expose a floor to moisture and heat differently. A steam-prohibited floor does not become suitable because the machine also has an ordinary washing mode. Buy for the treatment your floor actually permits.
How we reached this conclusion
Manufacturer descriptions establish different heating methods. Their heater and dock temperature figures are not comparable measurements at the floor surface.
S9’s stated heated window is ten minutes longer
For a buyer planning a heated cleaning session, the published limits are 30 minutes in Steam on S9 and 20 minutes in Hot Water on H15. That ten-minute difference is useful for planning, but cannot establish that S9 cleans 50% more floor.
How we reached this conclusion
30 − 20 = 10 minutes. The two modes apply different treatments, use different water rates and have no matched area test.
More clean water does not unlock a lower sofa
S9 carries 80 ml more clean water, a 10% capacity advantage. Its flat body is only about 0.06 inch lower, so that small height difference cannot promise access beneath furniture that blocks H15. Choose the heating method first, then check your refill routine and actual clearance.
How we reached this conclusion
Tank calculation: (880 − 800) ÷ 800 × 100 = 10%. Body calculation: 12.85 cm ÷ 2.54 = 5.06 inches, compared with 5.12 inches. Rounded dimensions need extra working room.

Meaningful differences
What changes the fit
| What changes | Dreame H15 Pro Heat | Tineco FLOOR ONE S9 Artist Steam | Why it matters |
|---|---|---|---|
| Heat at the floor | Hot water | Steam | The floor maker may allow one treatment and prohibit the other. |
| Heated-mode runtime | 20 minutes in Hot Water | 30 minutes in Steam | The ratings describe different treatments, not a matched efficiency test. |
| Clean tank | 800 ml | 880 ml | S9 carries 10% more clean water, without a verified gain in cleaned area. |
| Flat-body height | 5.12 inches | 12.85 cm, about 5.06 inches | The small nominal difference is not a dependable furniture-fit advantage. |
| Edge access | Front arm plus dual sides | Three-sided head | Both address front edges through different designs. |
