I have no idea, but I'm just wondering if the model number might be of help to those with much more knowledge than myself.
Is there a company that uses a "CH" prefix, or something similar?
Sorry if that's not helpful.
I swear I have seen this before but I do not know from who. The style I mean. It's some recycled mold.
The way that bin is designed as an afterthought makes me think whatever this used to be was originally a carpet shampooer with a big water tank and then they converted it to a vacuum cleaner.
Other than that I have never seen this before in my life. Probably made by some random "here today gone tomorrow" company and they made a hundred or two and that was it. It's probably from the mid or early 2000's.
I've definitely seen something similar as well but I can't quite put my finger on it. Mold looks similar to the Shark Pursuit canister but it's different from that one.
Very similar to this As Seen on TV "Storm Force" machine. I'd guess it's just a generic machine available from China for companies to slap their names on.
