These type of tests should also have turning stress test for AWD mower that have omni-wheel like the Dreame and Mova has. Do they use multipoint or tank turning?. With tank turning over time if the omni-wheel resist side moving it will destroy the grass near trees, bushes, flower beds, anything it has to navigate around. This has been seen with Mammotion mower that have gotten worse and worse with every update they add. Also with omni-wheel it would be good to know how they fair sideways on a slope will the omni-wheel make the front slide ? It would be good to know .
