Possibly worth buying
The black models were extremely common. All pro heats in that style are pretty much the same They came out in 1999 believe it or not. The pro heat 2x was indeed the upgraded version of this. I have a pro heat model that is the same thing, and they actually clean carpets pretty good. I once used it to clean someone’s whole house. A lot of times people will use these for not too long and later sell them. The nozzle isn’t cracked on both sides. Overall, the machine looks clean. It probably just needs a belt for the pump. If the price isn’t too high, I would buy it. The only issue with these pro heats are that the heater can get clogged up if you don’t do a rinse, and the suction isn’t the strongest.
