This is not a problem because it navigates via a laser.

I haven't tested it directly, but since the s5 max "scans" the environment with a laser, I don't think it's a problem (at dusk, under the bed, at least it can find its way around). Be careful with black, delicate objects, as it only detects by touch and could knock them over or move them (vase, wobbly keyboard stand or whatever). The laser has difficulties with dark surfaces).
