I've noticed there are many versions of this type tool. The Tornador/ The Ultimate Blaster/ The Twister/ plus a slew of no name knock offs. Just wondering if anyone has any opinions on a particular tool. Also I see one is available with a tank that adapts to the tool for post blow out rinsing. Is the tank a great addition, a hindrance or something that can be accomplished with just a spray bottle in the other hand? The tank certainly makes the tool more bulky and possibly less manuverable.
I have a Tornador Basic, so just the gun. For its intended purpose, they are an amazing tool that can really save you time and effort. It's great for pad blow outs and blasting trapped debris from between seats and hard to access interior spaces. I've also used it on engine bays. They are bloody brilliant on carpet mats too, blasting all of the embedded sand, hair and grass from the material. You can also use the tool in tandem with a vacuum, which is a handy trick on carpets too.
But.........................you would rarely if ever use one of these on a well-maintained car. If you were doing a lot of soccer mom cars, then this would be a massive help. Also, they can make more mess before it gets better, if that makes sense. You also need a really stout air compressor to run them, otherwise you'll have the compressor running constantly and the effectiveness of the vortex will diminish.
As for the ones with a tank, these are designed to work with cleaning chemicals such as APC. Never ever use one of these with a cleaning chemical without wearing a respirator. I don't have one for that reason.
Put it this way, I basically only use the Tornador when cleaning other peoples cars. So, unless you are making money off detailing, you'd probably never need one of these tools. As a hobbyist, it's nice to have, but not essential.
