Hi All,
Sorry to resurrect this old thread, but I wanted to post an alternative O-Ring that I sourced locally.
My original o-ring measured out pretty close to 2mm, but figured I would have a hard time finding metric O-rings locally and didn't want to wait for one to be shipped. So I found one at the local Ace that is pretty close and seems to work fine.
They carry a 1-1/8" OD x 1" ID x 1/16" CS O-ring that is closer to 2mm CS than I would have thought. This one is Danco brand #81 "O" Ring Stock Number 35713B.
It turns out that standard O-rings are listed at "nominal" size, and a 1/16" nominal O-ring is actually 0.070", which is about 1.8mm.

A German poster reported the Vorwerk VR100 replacement side brush belt is labeled 26 x 2 mm. Botvac could be different. Measure the old belt, drawing a circle with a compass.

I just finished this. D85 model I think. Anyway I got the vacuum at Best Buy in the US when there was a sale and also applied a coupon so it was a great deal. Belt operation took the better part of a morning, probably all morning if you factor in the part ordering and research.

I used this part and it is identical to the original as far as I can tell so I figure it's good for one or two years: ... 3255591810

I'm sure it will be somewhat faster to do next time. So far I've replaced the battery, the brush, the filter, now the side brush and belt and I also bought a new bumper to experiment with lowering and that worked out OK. The beast is pretty needy but still better than vacuuming all the time.
