I have a couple tornado products. I dont have their floor scrubber. I have found them to be solid products with good customer support so far. I have a tornado multi wash crb that I got on craigslist. It was missing a small part so I called their tech support, and they were incredibly helpful. I also have a huge 30+inch wide area vacuum that I use. It's the same as the windsor version. I think tornado is karcher made or something.
Tornado products are well built as with tenant. But service calls for both of them, I don't have positive comments for them. So if you want a balance one with built and service I will go for Windsor Karcher - this is if you don't know how to fix machine at the end and you want it service because the other too, you will wait for a loonnnnngggg time.
