Question about Roborock S5

Cutting a piece of wood to size? :-)

"Ramps" work well. I have a rule with a base that is just over 3 cm thick. Once a thin booklet slipped out, so that it formed a ramp from the floor to the rule. The robot then climbed the shelf ;-)

I would have thought of hands, which everyone normally has at home. Otherwise, you would almost have to build a ramp/ledge or possibly lay a carpet over the threshold. 4 cm is almost a wall for these hoover robots.
