Does anyone own a Robocut to cut hair and to groom thier dog?

Doe anyone own a robocut hair cutting device to groom thier dog? They have a new robocut that is built into a vacuum.

I am really interested in one of these to groom my Shih Tzu but I would really like to know if it works as well as the advertisement says. I think the robocut has been around for about 30 years or so. Seems like it wouldn't be around so long if it didn't work, but I'd still like to hear it from someone who really owns one. They have one now that has the Vacuum all combined with the hair cutting device. This is the one that I am most interested in. Does Someone have one that they are happy with? Is the motor very loud etc. Thanks!

I don't, but I think there's also something similar called the "flowbee" ?
