Model comparisons

Tineco S7 Steam vs S7 Stretch Steam vs S9 Artist Steam

What all three have in common

These are cordless powered floor washers with steam functions, separate clean- and dirty-water tanks, a roller, battery charging and ongoing tank/roller care. They are intended for indoor hard floors rather than carpeted rooms or upholstery. Each maker's examples do not replace the floor manufacturer’s advice: a sealed wood label alone does not prove that a specific finish tolerates heat and moisture. None is a canister boiler with an interchangeable glass squeegee, long hose and detail-brush kit. If those jobs are essential, compare a tool-based steamer such as the McCulloch MC1275.

FLOOR ONE S7 Steam: simpler body, two steam intensities

The exact S7 Steam manual names AUTO, STEAM and BOOST STEAM as appliance selections; SUCTION is selected in the app with Wi-Fi connected. Its two steam modes are the model's distinguishing control choice: the manual describes six steam openings for STEAM and two for BOOST STEAM. It estimates about 20 minutes in STEAM/BOOST STEAM and about 40 minutes in AUTO. Tineco lists 0.8 L clean and 0.72 L dirty capacity, and a 13.54 lb weight line. The manual explicitly says not to lay the body flat or lean it because dirty water can reach the motor. Choose this one when you do not need under-furniture reach and want the two steam settings; do not assume SUCTION is available from a physical switch.

FLOOR ONE S7 Stretch Steam: reach and a different mode set

The S7 Stretch Steam has its own exact US page and linked manual. Its manual describes AUTO, MAX, STEAM and SUCTION as separate modes, a 180-degree lay-flat design and a separate run-time claim of up to 30 minutes in STEAM; its store page advertises up to 80 minutes laid flat in any mode. Those are distinct claims, not interchangeable measures of steam endurance. It lists 0.88 L clean and 0.7 L dirty tanks, and labels 7.8 kg as item weight. It is the model to investigate when furniture clearance is a priority, but lay-flat use still has manual conditions and the claimed total runtime is not an independent result. See the S7 Stretch Steam review for its separate operating plan.

FLOOR ONE S9 Artist Steam: another model, not an S7 package

The S9 Artist Steam has its own US product page and manual, with an LCD display, 0.88 L clean tank, 0.75 L dirty tank and a Tineco-stated 30-minute STEAM runtime. Its page also describes a 75-minute maximum in Auto when laid flat. Tineco's exact product record and rendered store page disagreed about availability during review, so a search result should not be treated as proof of current stock. Read the S9 Artist Steam assessment for the mode and care limits. The separate S9 Artist Steam Pro name is not a shortcut to this model: its North American manual and seller identity are distinct questions.

Make the choice by task, not by the largest number

Need steam for a normal hard-floor pass, with no need to lie the machine down? Start with S7 Steam, while checking that an app-selected suction mode is acceptable. Need the documented 180-degree body angle for furniture clearance? Investigate S7 Stretch Steam and measure the actual gap; do not use the standard S7 page's name to infer that feature. Want the S9 format? Check its separate review, package and live seller name. In every case, the quoted runtime is a manufacturer estimate tied to a mode or position, not a guarantee that every room can be finished in one charge.

All three still require the buyer to empty and clean the dirty-water tank, keep the roller and filter clean and dry, and follow the manual's water restrictions. The manuals and product pages are more useful than a shared series name: they tell you what each body can do, which controls select it, and where its surface limits begin.
