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!

Best vacuum

I love everything about this vacuum. It is by far the best vacuum I’ve ever owned. 100% worth the money to spend and it is very comparable if not exact to a rainbow vacuum. You can clean everything with all the attachments it comes with. I highly recommend this vacuum.

W o r k s ! River of AIR

had a rex-air rainbow several years (decades), it's in trash now...can see how this design is an upgrade of sorts (by far) for water vacuuming / just remind all to keep it clean yourself after each use and clean the bottom and tank out.....

Sirene Vacuum Review

It seems to be a good vacuum cleaner very similar to our old Rainbow, but for considerbly less money.

This is my second one

I bought one years ago and loved it. After about 10 years the buttons stopped working but mind you my kids were pretty rough with it. But decided to get a robot vacuum for my next one and was so upset. It was terrible. So now went back to this one. Will never bug another vacuume again. In the 10 years I had my old one it always vacuumed as the same as the day I got it. It never lost suction.
