The Airobrush arrived this morning. I ordered a black one from a seller I buy from often and oh my, the speed of the roller is very fast, but super smooth to push. Pity the tool storer clip from the Numatic floor head can't fit on the neck of the Airobrush, thus being able to clip to the body of the Henry.
Still, I find the turn of speed very effective but not surprising. The sealed suction on Henry vacs have always been excellent with the HEPA Flo rubber seal dust bags fitted and being synthetic made, the bags are less likely to tear apart compared to the older green/brown paper ones.
