I've been using Orion for 3-4 years now. I like the chemicals that they use compared to others', they're more natural-based, and the cleaners always spend as much time as they need to. They've come out to do really minimal work up to cleaning an entire house, and they're always very quick and very prompt to come out when I need them. Their pricing is very comparable and I would even say it's probably less expensive than some of the other companies. The quality of their cleaning is incredible: we just bought a home a couple of weeks ago and the old owner told us that some of the stains wouldn't come out and we would have to replace the carpet. But Orion came in and was able to get out every single stain. The carpet will eventually have to be changed because it's old, but now it's stain-free!
