For low furniture, start with Dreame Aero Pro, since its full body is 3.88 inches high when flat and it keeps heated roller care. Aero gives the same clearance with an unheated care cycle. Tineco Stretch S6 is a candidate only for compatible wet-cleanable hard floors that offer full moving clearance beyond its nominal 5.1-inch body.

Look for floor washers that fit under low furniture by going on full-body height and not on a flat-hinge label or the measurement of the floor head.

Decision guide
Fit comes down to the tallest part that has to pass under the furniture.
A verified flat full-body height below four inches belongs to 2 of the 20 compared cleaners. Full-body height is recorded for 8 models, which means unknown dimensions are left out. The shortlist rests on measured specifications and does not claim that every other washer on the market is taller.
Subtract a 3.88-inch body from a four-inch gap and 0.12 inch remains, about 3 mm. That is a nominal gap and not a comfortable working allowance. Look at center supports, sagging fabric and uneven flooring. Where you can, try the fit instead of treating the front opening as the whole route.
Flat use of the H12 Pro FlexReach is withheld, because its exact North American manual forbids it while marketing promotes it. An advertised body or head height does not establish permission. Before relying on flat operation, ask Dreame to clarify the exact unit.
3 options

Dreame, Aero Pro
Low-profile hard-floor washer with a heated care dock. It helps when a taller lie-flat cleaner would have its body bump into the sofa.
Top pick ifHeated roller care combined with low furniture
With a four-inch gap, there is little room to spare for uneven floors or furniture

Dreame, Aero
Low-body washer that retains the under-furniture access and hair-cutting comb of the Aero Pro, but with a simpler care cycle that uses no heat.

Illustration from the maker. The faded outlines show a single cleaner tilting back. The orange swirl inside is only for illustration. Washing with it laid flat needs compatible hard floors and full working clearance. Keep it upright to carry and dock it.
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.

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
