Hi and thank you. I have done a lot of searching/research and it has helped a lot. For example, I was able to narrow down a robo-vac through google/BIFL, etc. Things I could not find or had the potential to be outdated or found a lot of conflicting/confusing answers to, I tried to compile from a list already on the go and memory. That said, I get your frustration. I hope you can get why I perceive some of the replies as grumpy.

Take care
