Suited to
Thresholds up to 1.3 in (33 mm) pass with room to spare. From there to its 1.38 in (35 mm) climb it is at its limit, and higher thresholds rule it out. It goes under furniture with a gap of 4.13 in (104.8 mm) or more: its height plus 0.2 in (5 mm). The vacuum finder applies both rules, and the methodology states them.
Its dock takes care of the bin and the mop, the most you can ask of a dock in the finder.
