no budget ceiling
The consensus flagship across 8 independent sources — 320°F steam and 22 kPa suction give it the deepest clean of any floor washer tested.
Fit ledger — need → measured evidence
■ The catch — co-equal billing, always
It's heavy, and steam guts the runtime. At 13.5 lb it's the heaviest washer here, and the 75-minute runtime collapses to roughly 30 minutes the moment you switch on steam — the exact feature you paid $949 for.
Dealbreaker? Runner-up №1 halves both the weight and the price ↓

Traps — this verdict avoids
Why the Tineco Floor One S9 Artist Steam is right for you
It avoids every trap below — and for anyone, no budget cap, it is the pick because it delivers:
Hot water isn't steam
Spec sheets blur the two. Hot-water models (Dreame H14 at 140°F, most cordless units) loosen sticky messes but do not sanitize — only true steam reaches 200°F+ at the roller.
Eco-mode runtime
Advertised runtime is a best-case Eco number. Steam and Max modes typically halve it — the flagship Tineco S9 goes from 75 minutes to roughly 30 minutes on steam.
The no-suction Dyson
Dyson's WashG1 and PencilWash have no suction at all — mechanical rollers only. They cannot pick up dry debris, so you have to sweep or vacuum the floor before you wash it.
