So I'm deciding buying between these two power rakes: Ryan Ren-O-Thin or the Bluebird PR22. The reason why I'm considering the PR22 is that they have an optional bagging attachment. However, I read that the bag can fill up quite fast. So the main question is, will having the bag be more efficient or be counter-productive to my work? And if I do end up going towards the Ryan, will buying a lawn vacuum be worthwhile? I have never power raked before so I got some noob questions . Thanks in advance!
