What is Max slope?
In short
Max slope is the steepest gradient a robot mower can handle, and it matters most on a plot with banks and level changes.
Max slope is the steepest gradient a robot mower can work on. Steep banks and sudden changes between lawn levels are where mowers stall, lose grip or leave stripes, so the figure matters more on a sloping plot than a flat one. The ratings in this group differ sharply. Dreame lists 80% and Mammotion lists 80%, while Einhell lists 35%. Check the steepest part of your own lawn against those numbers.
