Tineco Floor One S9 Artist Steam vs Roborock F25 Ultra Wet & Dry Vacuum

Both are cordless wet-dry vacuums with steam, self-cleaning docks and HEPA filtration. The Tineco S9 Artist Steam leans on a 320°F HyperSteam system, a 180° lay-flat body that reaches about 5 inches under furniture, and up to 75 minutes of runtime. The Roborock F25 Ultra adds app and voice control, a 5-minute dock dry, and a 2-year main warranty, but its 58 ratings average 4.2 and its spec sheet is inconsistent. Pick the Tineco for deep steam on greasy hard floors and low-clearance reach; pick the Roborock for a lighter, smarter machine with a longer warranty.

• Choose the Tineco Floor One S9 Artist Steam if you want the hottest steam, the flattest reach under beds and sofas, and the longest runtime for whole-home hard-floor cleaning.
• Choose the Roborock F25 Ultra if you want app and voice control, a quick-drying dock, and a two-year main warranty in a lighter machine.
