Compared to the Cordless proteam, it's less expensive, lighter, has more power, and uses hepa bags as standard it's drawback is it's battery life is shorter. This may be a permanent collection piece, it's very convenient!
It is the RD285, i was sent it as well as some other goodies from Wessel werk a while back when I still worked at the vacuum shop. I just kept using the term free flow cause i'm like 90% sure they're the same tool.
