Thankful for Sirena

34 years ago, I fell in love with water technology vacuum cleaning and purchased my first Rainbow. Recently my second Rainbow, of 18 years, stopped working and I was forced to make a decision to replace it or repair it. Thankfully, I discovered the Sirena Vacuum Cleaning System and was able to replace it for less than the repair cost. I'M LOVING MY SIRENA! I recommend the Sirena vacuum to anyone interested in a water technology cleaning system.

Really like it!!!

My recertified Sirena arrived safe and sound and was really easy to set up. It works GREAT and the water when I vacuumed my house was disgusting. I also have a Quantum X upright water vac but it was inconvenient to use the attachments. Love love love the water vacs so much!!! Thank you Sirena. I am pleased with my purchase!
