Stair Climbing Wheel Set for CRB

[Hoss]

Does anyone use the stair climbing wheel set with their CRB? I can't seem to find any information on how these are used - where they attach - and if they are used while cleaning stairs or simply transporting the CRB over stairs.

Many of my jobs are in strangely configured old mansions that have been chopped up into condos or apartments. Stairs can be a beast - the pitch on some would surely have to have been grandfathered or great-grandfathered in to be allowed under code. They often tack down wool/ oriental style runners that wear well but get pretty nasty. If the CRB could be easily navigated down them scrubbing as it went, that would save me quite a bit of time and effort using the Micro-Orbot.

Thanks!
