About this model

Vapor Chief Single Pro 75 Steam Cleaner is a boiler steam cleaner manufactured using a stainless-steel body and features advanced pressure and heating capabilities. The Italian-made Vapor Chief Single Pro 75 Steam Cleaner uses the power of steam to completely transform the area it is working on. Essentially a simple machine, the Vapor Chief Single Pro 75 Steam Cleaner works like a commercial grade tool, but at a residential price and ease of use!

Featuring an external heating coil located on the underside of the Single Pro 75 that can heat the water in your boiler to 315 – 320 degrees, Vapor Chief Single Pro 75 Steam Cleaner sanitizes as it cleans. Also, because this heating coil is under the unit rather that inside the unit, your coils will not erode and calcify over time. Vapor Chief Single Pro 75 Steam Cleaner utilizes a fully adjustable steam pressure control from zero to maximum and gives you the ability to customize your detail!


Vapor Chief Single Pro 75 Steam Cleaner Technical Specifications:

• 1700 watt external heater
• AISI 304 stainless steel boiler with a 3.1 (total volume) liter capacity
• 11 foot detachable hose
• Approximately 315-320 degree steam
• Now with 85 PSI!
• 13 foot power cord
• Stainless steel body
• Full accessory package


Also includes:

• LIFETIME boiler warranty
• LIFETIME heater warranty
• 3 year internal parts warranty


Attachments
Vapor Chief Single Pro 75 Steam Cleaner comes with several attachments including 4 large and 6 small round cleaning brushes, two extension pieces, a triangle head brush, two flat head brushes, and micro hose tips for precision detailing.


Main difference
The difference between the Vapor Chief Single Pro 75 Steam Cleaner and the Vapor Chief Refill 100 Steam Cleaner and Vapor Chief 125 Injection Steam Cleaner is this model is NOT a continuous fill model. This means after you run out of steam you must turn the steam machine off and allow the boiler and steam pressure tank to cool down before you can remove the threaded cap to add more water.


This model has a threaded, spring loaded cap to seal the water tank and build-up and hold steam pressure.

http://www.autogeekonline.net/gallery/data/3474/Vapor_Chief_006.JPG


Before you can remove the cap during use, you must turn off the steam machine allow some time for the unit to cool down so you can safely remove the cap.

Main difference
The difference between the Vapor Chief Refill 100 Steam Cleaner and the Vapor Chief Single Pro 75 Steam Cleaner is that this model IS a continuous fill model meaning as you use up water in the water tank to make steam, you can add more water at any time.

Note the cap is different than the cap on the Vapor Chief Refill 100 Steam Cleaner

http://www.autogeekonline.net/gallery/data/3474/Vapor_Chief_011.JPG



This cap simply pulls off and presses on, there's no pressure in the water tank and you can add more water at any time...

If you want continuous fill feature but don't think you need the ability to inject cleaning chemicals when steaming, this is the best option.

Now lets see this steamer in action!


Add tap water to the water tank and your all-purpose-cleaner to the other tank...

http://www.autogeekonline.net/gallery/data/3474/Vapor_Chief_034.JPG



After plugging the steam machine on, turn the power switch from the 0 to the 1

http://www.autogeekonline.net/gallery/data/3474/Vapor_Chief_035.JPG



It takes about 10 to 12 minutes for the boiler to heat up the water and create steam and pressure.

http://www.autogeekonline.net/gallery/data/3474/Vapor_Chief_062.JPG



While the Vapor Chief Steam Cleaner is heating up, let me see if I can find something REALLY dirty to test it out on...

http://www.autogeekonline.net/gallery/data/3474/Vapor_Chief_036.JPG



Found something - the floor inside our Competition Ready Van!

http://www.autogeekonline.net/gallery/data/3474/Vapor_Chief_037.JPG


Note I'm using the SCANGRIP Multimatch and the SCANGRIP Tripod to light up my shots.

I stated back in December of 2016 that I look for a swirl finder light that not only shows swirls but also works great for photography and video work and you read my comments about that here (https://www.autogeekonline.net/forum/new-car-care-products/106802-scangrip-sunmatch-swirl-finder-light-product-review-mike-phillips.html)

http://www.autogeekonline.net/gallery/data/3474/Vapor_Chief_038.JPG

The SCANGRIP Multimatch lights up a set pretty good!

http://www.autogeekonline.net/gallery/data/3474/Vapor_Chief_041.JPG

http://www.autogeekonline.net/gallery/data/3474/Vapor_Chief_042.JPG



Meanwhile, the steam machine is just about up to full temperature and full pressure....

http://www.autogeekonline.net/gallery/data/3474/Vapor_Chief_043.JPG



Note the green light is off?

That's because it's >>>BLINKING<<< while it's heating up and I captured this shot in-between >blinks<

http://www.autogeekonline.net/gallery/data/3474/Vapor_Chief_044.JPG



Once the steam machine comes up to full temperature and pressure the light will go from blinking to constant [ON] like you see in the below picture.

http://www.autogeekonline.net/gallery/data/3474/Vapor_Chief_045.JPG

http://www.autogeekonline.net/gallery/data/3474/Vapor_Chief_046.JPG



Here's a tape-line to help show before and after results...

http://www.autogeekonline.net/gallery/data/3474/Vapor_Chief_047.JPG


Here I'm pulling the trigger for steam...

http://www.autogeekonline.net/gallery/data/3474/Vapor_Chief_048.JPG



Here's where the trigger is located for steam....

http://www.autogeekonline.net/gallery/data/3474/Vapor_Chief_059.JPG


On the back, top of the handle there's a button for your cleaning chemical

http://www.autogeekonline.net/gallery/data/3474/Vapor_Chief_060.JPG


Time to start steam cleaning...

Wait for it....

http://www.autogeekonline.net/gallery/data/3474/Vapor_Chief_053.JPG











BOOM!
Here's the floor both cleaned and SANITIZED!

http://www.autogeekonline.net/gallery/data/3474/Vapor_Chief_054.JPG



Here's another favorite and handy tool and that's the SCANGRIP I-VIEW, which is perfect for interior detailing as it lights up your work area...

http://www.autogeekonline.net/gallery/data/3474/Vapor_Chief_055.JPG

http://www.autogeekonline.net/gallery/data/3474/Vapor_Chief_056.JPG



Here's the job completed...

http://www.autogeekonline.net/gallery/data/3474/Vapor_Chief_057.JPG

http://www.autogeekonline.net/gallery/data/3474/Vapor_Chief_058.JPG





2 very important features that come with professional grade steam machines like the Vapor Chief Injection Model is,


1 Continuous fill - This means as you run out of water you can simply add more water on-the-fly, no need to wait for the unit to cool down so you can remove the water tank lid.

2 Use tap water - that's right, because the heating element is on the outside of the boiler there's no need to use distilled water.



Here's my buddy and co-worker Will adding more water from a hose at our utility sink in the warehouse...

Comments and review


Comments...

When people ask me about steam cleaning, I use a simple analogy to explain how well it works....


Say you've been working with your hands all day on something greasy and grimy, for example, replacing the starter motor on an old Ford. (Chevys never break).

Your hands get this black oily sludge on them but it also embeds down into the pores of your skin. You could wash your hands with soap and COLD water and with enough scrubbing finally get your hands clean or you could wash your hands with soap and HOT water and I think you'll agree it will be a lot faster and a lot easier to get your hands clean.


That's how steam machines work. They heat up the surface causing it to expand a little and then the high pressure and high heat of the steam loosens and dissolves dirt and grime so you can easily wipe it away.

You can use steam by itself or incorporate one of the many tools included with all Vapor Chief Steam Cleaners and increase the cleaning ability of the steam.



Review
The Vapor Chief Steam Cleaners are truly built like TANKS. Yes, like a military tank. They are sturdy and well-built. Just handling one you can tell no sane person is ever going to break one. The heating elements work fast to bring up both the temperature and the pressure so you can get busy cleaning. 10-12 minutes is all it takes. By the time you turn any of these steam machine on and then get your car in position or whatever it is you're cleaning it will be ready to go.

Time behind the tool
Just like anything, in order to become an expert at cleaning with steam you need to invest some time behind the tool. It's not hard but practice does hone your skills.

Sanitizing
The thing I like about cleaning with steam is at the same time you're cleaning a surface you're also sanitizing the surface and that's a cool feature that can stop germs in their tracks and keep them from affecting you. I don't know about you, but I appreciate my health and it's never any fun getting sick with a cold or flue and then missing my fun job. So sanitizing with steam is an extra level of protection you can't get with chemicals along.


If you've been sitting on the fence about getting a steam cleaner and one of the things that's been stopping you from making the decision is quality, then have no fear. The Vapor Chief line of steam cleaners will probably outlast you and most any other tool you've purchased.


There's lots of cheap, plastic steam machines on the market, for a hundred buck or so you can spray some steam around. But when you have work to do, day-in and day-out, then it's time to invest in a real tool not a wanna-be tool.

Thank you for commenting Bill..


I was told we had a lot of requests for the Vapor Steam brand of polishers so we listened to our customer feedback and now they are available on the AG store.


I'm curious to see how sales are. It's a very rugged tool with all the bells and whistles someone would want in a professional grade steam cleaner. Each time I get a project car into the garage where I can use steam I'll document one of these steam machines in action.


Stay tuned...

Great write up!

What are your thoughts on detergent injection in terms of what dilution to use with your cleaner of choice? I'm just now getting into experimenting with something other than the Dupray APC which is made for steam injection and am a little unsure as to how I should mix my APC. I'm going to try Poorboys APC+D at 64:1 at first and see how I like it, but I worry about mixing it too strong. There really isn't much info out there when it comes to what chemicals and how they react with steam injection

Mike, what is the reason it says to only use tap water and not distilled water?

If im not mistaken they use some type of electrical current which goes thru the water to monitor the level in the boiler. Distilled water is not conductive, tap water is, and therefore the machine would probably assume the boiler is empty and wouldn't heat up if filled with distilled water.

I could be wrong but I thought I remember reading that somewhere

Great question Shane...

I think in the video I covered this topic by saying to dilute whatever product you're going to use to the normal dilution you would use it without steam injection and that is the rule of thumb.

So if an APC states to dilute at 4:1 then mix up your product accordingly for a the holding tank you're using with the system you own. In this case, I had to do the math, (not my strong point), and the way I did it was to first see what I had for a measuring cup.

I have a 1000 ml or milliliter measuring cup in the garage for just this type of thing.

Next I had to convert 5 liters to milliliters which is simple as it's 5000 milliliters.

Now to figure 4:1 dilution this means 4 parts water and 1 part of the product you want to dilute which will give you a total of 5 parts.

This is where I was lucky as it's pretty easy to figure out how many times "5 parts" go into 5000 and the answer if 5. So if I need a total of 5 parts of 1000 milliliters that means I'll need 4000 milliliters of water and 1000 milliliters of product and that's what I mixed for the video.


I think that's right. I'll cede to any math whizzes in the audience.


The bigger point is that just because you're using steam you don't have to or need to change the dilution of a product.

Mike, what is the reason it says to only use tap water and not distilled water?




Great question Eric.

With Vapor Chief, the heating element is on the OUTSIDE of the stainless steel boiler not the inside.

Thus the heating element is NOT coming into contact with any dissolved minerals and other substances found in tap water so there's no physical contact or interaction between these things thus no problems. There is a problem when the heating element is in the inside of the boiler and whatever chemical changes take place to the heating element and the boiler itself from the interaction between the two will tend to wear-out or break the unit plus void any warranty.

At least the above is my understanding....
