Self-cleaning on charge against 90 °C (194 °F)
Which floor washer looks after its own roller best?
Both makers have understood the failure mode of the category. They have answered it differently, and only one of them publishes a number.
| Compared on | FCV 4 Natural N | H12 Pro FlexReach |
|---|---|---|
| Roller wash temperature | Not stated in the listing | 90 °C (194 °F) |
| Drying cycle | Runs during charging | 5 minutes |
| Suction | Not stated | 18,000 Pa |
| Runtime | approx. 45 minutes | Not stated |
| Filtration | Two-stage, pleated plus foam | Not stated |
| Carpet | Short-pile rated | Hard floors only |
| Listed on amazon.com | No | No |
A tick marks the better answer on that line only. Counting ticks does not decide the page — the two verdicts below do, because these machines answer different questions.
No amazon.com listing was found for this one. We hold references for other markets but none for the United States, so it may not be buyable here — which is the first thing to weigh against anything below.
Buy the Kärcher for the cycle that runs on charge — it removes the step people skip — and for the two-stage filtration and the stairs mode.

Buy the Dreame for the stated 90 °C (194 °F), the hottest roller wash on the site. On grease and on smell, hotter genuinely does more.
A cycle you cannot forget beats a hotter one you have to remember, which argues for the Kärcher. But 90 °C (194 °F) against an unstated temperature is not a comparison — it is one figure against silence.
Only if you have short-pile carpet or rugs. On carpet a floor washer refreshes rather than deep cleans; spray extraction is a different process with far more recovery.
4 modes · 45 min · dirt sensor · two-stage filter · self-cleaning on charge
Four modes including a stairs mode, and a self-cleaning cycle that runs while the machine charges.
Best for: A house with mixed floors and stairs, cleaned weekly, where the machine has to look after itself
18,000 Pa · 90 °C (194 °F) wash · 5 min drying · 180° flat
Ninety-degree roller washing and five-minute drying — the two specifications that decide whether the machine smells.
Best for: Hard floors in a family home — spills, paw prints and daily crumbs, cleaned in one pass
