The catch
Dreame H12 Pro FlexReach
Flat use is held back: the North American manual forbids it, while marketing promotes it. Dry-only Suction is unresolved as well. Rely on neither claim until the exact unit has been clarified.
Side by side
On suitable hard floors where low reach is not needed, H12 is the one with the active hair-cutting comb. Where the whole machine fits, Stretch S6 is the one for documented flat washing. H12 flat use is withheld because the manual and marketing conflict. Powered roller care works on both with their specified dock setup, but tanks, filters and washed parts still need manual attention.
Before you buy
Flat washing is explicitly permitted in the S6's manual. The exact H12 manual prohibits it, marketing notwithstanding. On a low-furniture route, pick from the permitted operation and check the full moving clearance instead of comparing two body numbers.
Where this comes from
The S6's 5.1-inch measurement gives a nominal body height. It does not amount to a full clearance drawing.

The catch
The nominal 5.1-inch body figure is no promise of full working clearance. Check that the head, wheels and handle all fit along the whole route

H12 hair management weighed against the documented flat washing of Stretch S6, with the H12 manual conflict and the care requirements of both machines kept intact.
On suitable hard floors where low reach is not needed, H12 is the one with the active hair-cutting comb. Where the whole machine fits, Stretch S6 is the one for documented flat washing. H12 flat use is withheld because the manual and marketing conflict. Powered roller care works on both with their specified dock setup, but tanks, filters and washed parts still need manual attention.
Which one fits
H12 comes with an active cutting comb. Manual care is still needed, and flat use is not permitted.
S6 allows flat use on suitable hard floors, but only where the whole moving machine fits. The H12 instructions conflict.
Each needs a powered setup and still leaves manual care and full drying of washed parts.
Each is restricted to suitable hard floors.
In practice
Flat washing is explicitly permitted in the S6's manual. The exact H12 manual prohibits it, marketing notwithstanding. On a low-furniture route, pick from the permitted operation and check the full moving clearance instead of comparing two body numbers.
The S6's 5.1-inch measurement gives a nominal body height. It does not amount to a full clearance drawing.
The S6 has 20 ml more nominal clean water. That is too small a basis for a whole-home or fewer-refill claim without matched water-use evidence. What the evidence supports is a choice between floor access and a hair-cutting mechanism.
800 minus 780 leaves 20 ml. Nothing is inferred about cleaned area.
The comb on the H12 is aimed at wrapped hair. Both machines can dry the roller with their required powered setup. Heated air neither clears every channel nor dries a separately washed filter. When low reach isn't needed and wrapping is what bothers you, the cutting mechanism is the H12 feature that counts.
Both still need hands-on care for the roller, tank and filter. No comparative care-time or pickup test is established.

Dreame, H12 Pro FlexReach
Washes suitable hard floors, with a hair-cutting comb and powered roller care that depends on the specified dock setup. Whether it can be used flat, and whether dry-only Suction works, stays unresolved because the manual and the marketing contradict each other.

Tineco, FLOOR ONE Stretch S6
Washes compatible wet-cleanable hard floors under furniture, provided the whole machine can move through the space. Powered roller drying requires the specified dock setup, and some parts still need manual care.
Spec by spec
| Spec | Dreame H12 Pro FlexReach | Tineco FLOOR ONE Stretch S6 | In practice |
|---|---|---|---|
| Flat use | Withheld: manual conflicts with marketing | Explicitly permitted on suitable hard floors | Look at the S6 as a whole moving machine beyond its nominal 5.1-inch body. |
| Clean tank | 780 ml | 800 ml | The nominal capacities are only 20 ml apart. |
| Hair management | Active TangleCut comb | Manual roller care | Addressing wrapping with a cutting mechanism does not prove better pickup or zero maintenance. |
| Powered roller care | Specified charging, battery and water setup | Specified charging, battery and water setup | Tank, filter and roller care and complete drying of manually washed parts are left to you on both. |
Trade-offs
Change of plan
Go with Dreame H12 Pro FlexReach. An active cutting comb comes with the H12, but that is not a promise of no maintenance. Flat use stays withheld because the manual and marketing conflict
Go with Tineco FLOOR ONE Stretch S6. The S6 allows that kind of operation. Its powered care depends on the dock setup and is no substitute for manual care
Decision guide
Pick H12 for the active hair-cutting comb on suitable hard floors when you do not need low reach. Pick Stretch S6 for documented flat washing where the whole machine fits. H12 flat use is withheld, as its manual and marketing conflict. Each machine gives powered roller care through its specified dock setup, yet tanks, filters and washed parts still need manual attention.
Flat washing is explicitly permitted in the manual for the S6. The exact H12 manual prohibits it, marketing notwithstanding. On a low-furniture route, choose from the operation that is permitted and check the full moving clearance instead of comparing two body numbers. The 5.1-inch figure for the S6 is a nominal body height and not a complete clearance drawing.
Nominal clean water is 20 ml higher on the S6. Without matched water-use evidence, that is too small a basis for claiming it suits a whole home or needs fewer refills. What the evidence supports is a choice between floor access and a hair-cutting mechanism. 800 minus 780 equals 20 ml. No cleaned-area result is inferred.
The comb on the H12 goes after wrapped hair. With the powered setup each requires, both machines can dry the roller. Heated air will not clear every channel or dry a filter you washed separately. Where low reach is not needed and wrapping is what bothers you, the cutting mechanism is the H12 feature that counts. Manual roller, tank and filter care remains on both. No comparative test of care time or pickup exists.
