The Sirena is a good machine. I would say would compare more to an older Rainbow. It does not have a brushless motor. No direct connect wands. Moves 90 CFM on High. a bit larger water basin. Both Sirena and Rainbow are water based/separator machines.
Like I have said previously; I am not a fan of the power nozzle. It's not a bad nozzle, there is a very large dead side where the belt runs. It does, however, seem to do a good job cleaning. I don't care for the adjustments. I wish there were more settings, and they were more clearly marked. I wish it had a headlight. I think these are just my preferences rather than negatives with the nozzle.
I wanted a new Rainbow, but my checkbook said I couldn't have it, I got a very good price for a new in the box Sirena on Ebay last February. I have had no complaints in the last almost year I have owned mine. Any questions you have Sirena has responded within a day with an answer or solution. As I was saying to myself yesterday, "would you buy another one?" "Yes, self, I would."
