The catch
Tineco FLOOR ONE i6 Stretch
The US specification table documents no Auto mode
Side by side
i6 Stretch fits you if you want lie-flat access and prefer manual Eco and Max controls. Stretch S6 is the better choice for automatic dirt sensing and documented heated roller drying. Because their body height and clean-tank size are similar, neither gains a meaningful advantage in fitting under furniture. Flat washing with the S6 depends on compatible wet-cleanable hard floors and full moving clearance beyond its nominal 5.1-inch body. S6 powered care depends on the dock setup, and manual care plus complete drying of washed parts remain.
Before you buy
Do not choose between these two for a sofa gap near five inches. Both need about 5.1 inches for their flat body, before allowing for movement. A lower-bodied machine is a more relevant change than switching between these models. S6 flat washing requires compatible wet-cleanable hard floors and full moving clearance beyond its nominal 5.1-inch body.
Where this comes from
13 cm ÷ 2.54 = 5.12 inches. Since the S6 figure is rounded, the apparent hundredths of an inch do not amount to a meaningful advantage.
The catch
The US specification table documents no Auto mode
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

Which one fits
i6 gives you Eco and Max.
Auto sensing is on S6.
Both lie flat. A low bed with enough clearance. S6 flat washing requires compatible wet-cleanable hard floors and full moving clearance beyond its nominal 5.1-inch body.
Each clean tank holds 800 ml.
In practice
Do not choose between these two for a sofa gap near five inches. Both need about 5.1 inches for their flat body, before allowing for movement. A lower-bodied machine is a more relevant change than switching between these models. S6 flat washing requires compatible wet-cleanable hard floors and full moving clearance beyond its nominal 5.1-inch body.
13 cm ÷ 2.54 = 5.12 inches. Since the S6 figure is rounded, the apparent hundredths of an inch do not amount to a meaningful advantage.
i6 Stretch is the pick if you want the same selected cleaning level throughout a room. On a route that alternates between crumbs, muddy prints and cleaner patches, Stretch S6 is the better fit because its Auto mode can adjust along the way.
The US i6 table lists Eco and Max, while Stretch S6 documents iLoop automatic dirt sensing. That tells you how the controls behave. It does not show that one cleans better in measurements.
Each carries 800 ml of clean water and lists 720 ml for collected water. Capacity is therefore a weak reason to upgrade, yet it does not show how many rooms either will finish on one fill.
How fast water is dispensed, how much is already on the floor and how many passes you repeat all affect refill and emptying intervals. No matched area test is available here.

Tineco, i6 Stretch
Lie-flat washer with manual Eco and Max settings. It makes sense when getting under a bed counts for more than automatic dirt sensing.

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 | Tineco FLOOR ONE i6 Stretch | Tineco FLOOR ONE Stretch S6 | In practice |
|---|---|---|---|
| Modes | Eco and Max | Auto, Max and water suction | With Auto, the cleaner responds differently as the job goes on. |
| Flat-body height | 13 cm, about 5.12 inches | About 5.1 inches | Rounded figures do not prove a useful clearance difference. S6 flat washing requires compatible wet-cleanable hard floors and full moving clearance beyond its nominal 5.1-inch body. |
| Clean and dirty tanks | 800 and 720 ml | 800 and 720 ml | Both have the same nominal tank capacity. |
| Maximum runtime | 40 minutes | 40 minutes | Neither choice is justified by headline runtime on its own. |
Trade-offs
Change of plan
Go with Tineco FLOOR ONE i6 Stretch. In the US specification, the modes are Eco and Max, with no Auto
Go with Tineco FLOOR ONE Stretch S6. Stretch S6 pairs dirt sensing with heated roller care. That powered care needs the S6 dock setup, and manual care along with complete drying of washed parts remains.
Decision guide
Go with i6 Stretch for lie-flat access and manual Eco and Max controls. Go with Stretch S6 for automatic dirt sensing and documented heated roller drying. Their similar body height and clean-tank size mean neither has a real edge for fitting under furniture. On the S6, flat washing requires compatible wet-cleanable hard floors and full moving clearance beyond its nominal 5.1-inch body. S6 powered care requires its dock setup. Manual care and complete drying of washed parts remain.
A sofa gap near five inches is not a reason to pick one of these over the other. Each needs about 5.1 inches for its flat body, and that is before any allowance for movement. Switching to a machine with a lower body would matter more than switching between these two. Flat washing with the S6 requires compatible wet-cleanable hard floors and full moving clearance beyond its nominal 5.1-inch body. 13 cm ÷ 2.54 = 5.12 inches. The S6 figure is rounded, so the hundredths of an inch that appear are not a real advantage.
Buyers who want one chosen cleaning level held across a room are served by i6 Stretch. Where a route alternates between crumbs, muddy prints and cleaner patches, Stretch S6 fits better because its Auto mode adjusts along the way. The US i6 table lists Eco and Max, while Stretch S6 documents iLoop automatic dirt sensing. That tells you how the controls behave and not that one cleans better by measurement.
Each holds 800 ml of clean water and lists 720 ml for collected water, which makes capacity a weak reason to upgrade. It still does not tell you how many rooms either one finishes on a single fill. How fast water is dispensed, how much is already on the floor and how many passes you repeat all change the refill and emptying intervals. There is no matched area test to draw on here.
