Dyson V15s Detect Submarine vs Tineco Floor One S9 Artist Steam
Quick take: The Dyson V15s Detect Submarine costs $25 less; the Tineco Floor One S9 Artist Steam runs longer per charge (75 vs 60 min).
Which one to buy
Carpet is the dividing line. The Tineco Floor One S9 Artist Steam cleans hard floors only. The Dyson V15s Detect Submarine is a full V15 stick that also has a wet roller head, so it can vacuum carpet, stairs and rugs, then mop the kitchen. If you have any carpet and want one machine, that decides it.
For hard floors alone, the Tineco is the stronger tool. It vacuums and washes in the same pass, adds 320°F steam for dried-on grease, and its owners point to lab testing that tied it for the best stain-removal score among hard floor cleaners and found it left floors drier than most washers. Its dock hot-washes and dries the roller after every session, it lies flat to about 5 inches to reach under furniture, and its water tank holds 880 ml against the Dyson's 300 ml. Its drawbacks: a 45-60 second steam warm-up, about 13.5 lbs of weight, and a dirty-water tank you still rinse by hand.
Dyson owners describe the Submarine head as a supplemental mop. It has no suction of its own, so you vacuum first and then swap heads, and it streaks on large wet spills, though it lifts most dried spots in a pass or two. The dry side is where the machine shines: the laser, the pet-hair pickup and the sealed HEPA filtration all earn praise. Durability is the serious complaint, with a recurring pattern of units failing just past the 2-year warranty and costly cyclone repairs. It also needs the trigger held, and it is loud at 81 dB.
The Tineco's 22,000 Pa and the Dyson's 240 AW are different measurements and cannot be compared. Hard floors throughout and real grime to fight: buy the Tineco. Carpet plus occasional mopping: the Dyson fits, but it is now discontinued and Dyson's replacement is the V16 Piston Animal Submarine at $1,100, so register the warranty on whichever you buy.
Dyson V15s Detect Submarine
Now discontinued, but best if your home mixes carpet and hard floors and you want one stick that vacuums everything and mops dried spots occasionally.
Tineco Floor One S9 Artist Steam
Go this way if your home is all hard floors and you want true wash-and-vacuum in one pass, plus steam for set-in grease and stains.

Dyson V15s Detect Submarine vs Tineco Floor One S9 Artist Steam: common questions
Does the Dyson V15s Submarine vacuum and mop at the same time like the Tineco?▾
No. Its owners say the Submarine head mops only and has no suction, so you vacuum with the standard head first and then swap heads for a wet pass. The Tineco vacuums and washes in a single pass, which is faster on large hard-floor areas.
Can the Tineco S9 Artist Steam clean carpet?▾
No, it is a hard-floor-only machine with no carpet or rug capability. A home with rugs or carpeted rooms would still need a separate vacuum, which is the main reason to consider the Dyson, since it converts back to a normal V15 for carpet and stairs.
Is the Tineco's steam mode worth paying for?▾
If you deal with cooking grease, pet accidents or tracked-in grime that a wet pass leaves behind, yes. Its owners cite lab testing that tied it for the best stain-removal score among hard floor cleaners. Plan for a 45-60 second warm-up before each steam session.
Which is more reliable long term?▾
Dyson owners report a recurring pattern of units failing shortly after the 2-year warranty, plus battery fade after a year or two. Tineco owners cite a below-average rate of dealbreaker problems. Both carry a 2-year warranty, so register whichever you buy.
