The Ultra Steam is the only machine here that puts steam and a hot-water wash in the same cordless body. Steam at up to 356F softens baked-on kitchen grease and sticky juice rings that a cold or warm roller only smears, and the 187F hot-water supply helps the roller shed what it picks up. A blue light projects ahead of the head and makes dust and crumbs on dark floors visible, which is a smarter aid than a plain white headlight.
That heat comes with floor rules. Steam is for sealed tile, vinyl and sealed hardwood in good condition, not for laminate with open seams or worn finishes. If your home is mostly laminate, the F25 GT Neo is the safer buy, because it relies on a roller and a self-clean cycle without steam. The Ultra Steam also sits near the top of the price ladder, well above the F25 GT Gen 2.
AI-enhanced wheels help the machine move itself, which cuts the push effort that a full tank otherwise demands. Because steam leaves mineral scale in hard-water homes, use filtered water and descale the steam path on the maker's schedule, then empty the dirty tank after each use.
