Side by side
Dreame H15 Pro Heat vs Tineco S9 Artist Steam: Floor-care permission differs for hot-water washing and steam
Quick verdict
For washing with heated water and an edge arm that reaches the front, choose H15 Pro Heat. If your floor specifically permits steam and you want the longer stated heated-mode window, choose S9 Artist Steam. Read the floor care rules first, since hot water and steam are different treatments.
Before you buy
Why, and what it costs you
Settle the heating method before looking at temperatures
A floor meets moisture and heat differently under steam than under heated-water washing. If steam is prohibited on your floor, the machine's ordinary washing mode doesn't make it suitable. Buy for the treatment your floor permits.
Where this comes from
The manufacturers describe different heating methods. Heater and dock temperature figures from each are not comparable measurements at the floor surface.

How we worked this out
The manufacturers describe different heating methods. Heater and dock temperature figures from each are not comparable measurements at the floor surface.
The S9 states a heated window that is ten minutes longer
If you're planning a heated cleaning session, the published limits are 30 minutes in Steam on S9 and 20 minutes in Hot Water on H15. The ten-minute gap helps with planning, but it cannot show that S9 cleans 50% more floor.
How we worked this out
30 − 20 = 10 minutes. The modes apply different treatments and use different water rates, and no matched area test exists.
A larger tank does not get you under a lower sofa
S9 holds 80 ml more clean water, which is a 10% capacity advantage. Its flat body sits only about 0.06 inch lower, and a difference that small cannot promise access beneath furniture that blocks H15. Settle on the heating method first, then check your refill routine and actual clearance.
How we worked this out
Tank calculation: (880 − 800) ÷ 800 × 100 = 10%. Body calculation: 12.85 cm ÷ 2.54 = 5.06 inches, against 5.12 inches. Since the dimensions are rounded, leave extra working room.

Spec by spec
Where they really differ
| Spec | Dreame H15 Pro Heat | Tineco FLOOR ONE S9 Artist Steam | In practice |
|---|---|---|---|
| Heat at the floor | Hot water | Steam | A floor maker can permit one treatment and ban the other. |
| Heated-mode runtime | 20 minutes in Hot Water | 30 minutes in Steam | These ratings are for different treatments and do not come from a matched efficiency test. |
| Clean tank | 800 ml | 880 ml | S9 holds 10% more clean water, though no gain in cleaned area is verified. |
| Flat-body height | 5.12 inches | 12.85 cm, about 5.06 inches | A nominal difference that small can't be relied on as a furniture-fit advantage. |
| Edge access | Front arm plus dual sides | Three-sided head | Each tackles front edges with its own design. |

Decision guide
How to decide
H15 Pro Heat is the answer if you want heated water washing together with a front-reaching edge arm. S9 Artist Steam is the answer if your floor specifically permits steam and the longer stated heated-mode window matters to you. Look at the floor care rules before anything else, because hot water and steam are different treatments.
Settle the heating method before looking at temperatures
A floor meets moisture and heat differently under steam than under heated-water washing. A floor that prohibits steam does not become suitable because a machine also has an ordinary washing mode. Buy for the treatment your floor permits. The manufacturer descriptions establish different heating methods, and the heater and dock temperature figures are not comparable measurements at the floor surface.
The S9 states a heated window that is ten minutes longer
If you are planning a heated cleaning session, the published limits are 30 minutes in Steam on the S9 and 20 minutes in Hot Water on the H15. Ten minutes of difference helps with planning, yet it does not show that the S9 cleans 50% more floor. 30 − 20 = 10 minutes. The two modes apply different treatments, use different water rates and lack a matched area test.
A larger tank does not get you under a lower sofa
The S9 holds 80 ml more clean water, a 10% capacity advantage. Its flat body sits only about 0.06 inch lower, and a difference that small cannot promise access under furniture that blocks the H15. Settle on the heating method first, then check your refill routine and the actual clearance. Tank calculation: (880 − 800) ÷ 800 × 100 = 10%. Body calculation: 12.85 cm ÷ 2.54 = 5.06 inches, compared with 5.12 inches. Rounded dimensions call for extra working room.
