Soft / Power / Pressure Wash
Soft Wash?
The straight answer is: you’ll want to go with steam Shampoo over Hot shampoo, if only because this is the option that works well and is the most practical.
Shampooing the carpeting will use water just like the steam cleaning with the additional element of the shampoo, which helps to bring dirt to the surface before you need to scrub it away.
If you shampoo your carpet though, not only does it need to be rinsed with hot water too, but that moisture needs to be extracted as well. You can’t just let it dry as you would do with steam cleaning
Power Wash
Ultimately, you can rest assured that you are getting a lot of cleaning power with both of these methods. Your carpeting will no doubt be cleaner regardless of the method, but with steam cleaning, you’re killing bacteria and germs along with stains.
You can’t clean stains that are too deep, but you can prevent further dirt from rising to the surface.
You can also get rid of the eggs of pests when you use steam cleaning as well, because of the high temperature. This all-natural method might just benefit you more in the long term.
Pressure Wash
Steam cleaning and shampooing both use water to clean your carpet, but shampooing uses a lot more moisture. This means that it can take as long as 48 hours for your carpet to dry once you’re done with the shampooing process.
By contrast, when you only steam clean your carpet, you’re using a lot less water and your carpet will therefore be dry in just a few hours. Especially if you have a family running around or you need to walk on your carpet again, you might prefer a shorter cleaning time.
