Okay I have vacuums that are great for cleaning the interior of my car for the most part. I think I'll do this for all the nooks and crannies where little crumbs are hiding. I open it and it looks like any other car vacuum cleaner. I put on a crevice nozzle (there are about 4 nozzles in the kit). I start using it and to my surprise it does a little "Dyson" action. The cyclonic action works great in tight spaces. Has a carpet brush with flexible bristles. Will it replace a shop vacuum? NO. Will he get those little crumbs and baby bits. YES SIR
