I also have a CF1000. I simply turn it off, turn hose taps off & unscrew the pipes still left in the tank. Take the canister to the sink & rinse everything under the tap. most may say thats not the way to do it but I've been doing it that way for almost a year with no problems at all.
I have made a cleaner for the pipes to, 15kg fishing line with an old bottle brush tied to the end. feed the line through the pipe (line has two large swivels to weight it) & pull the bottle brush through. only takes me bout half an hour for the whole lot.
