I am so thrilled with my recertified Sirena. I am absolutely shocked with how pristine my recertified purchase is! This vacuum looks and runs, like a new machine! It's in perfect working order. I was so fed up with machines that had no suction. I swore that no matter what I had to do I would find a machine that worked! I was nervous to buy online, but many years ago my mother had a water filtration unit & absolutely swore it was the best. Even though I could not be sure, I decided to buy one through the recertified option. I felt I could deal with a nick or two if it meant I got a machine with good suction. Well, I didn't get good, I got great! The machine is much quieter than I thought it would be, and I love the suction power. It really works!! I will admit that it is a bit more effort to properly make sure you empty the water and store main unit with out water reservoir, but the job it's doing is amazing. I feel like crying over all the money I wasted having to repeatedly buy new machines, but I won't cause I'm so happy now. Oh, and watch the videos! They are super helpful if you have a question! Worth every penny I paid this time! 😆
