They all pitched in exactly the same way, "safer than stress cleaning", "clean up without stress", "the safest way to clean your house". Is cold washing really a better way to clean your house?
To begin with, we need to know how both systems work to fully answer the question in your hand. Both approaches are very straightforward and essentially the exact same thing.

There are important differences between those systems here. With tension cleaning, water is creating pressure so it sprays harder to eliminate mold, dirt, etc.
Is pressure cleaning safe? Yes. Like anything, even if you do not use the tool correctly, it is possible to suffer damage. But if you use a pressure cleaning program correctly, you will have zero damage to any surface and you will have the ability to clean surfaces with small, sometimes small compounds.
This system usually contains a greater amount of water in the tube than later pressurized water. Soft washing also uses a greater concentration of chemicals or cleaning options when cleaning a house.
Where a pressure cleaner may have the ability to eliminate some spills of dirt without compounds due to pressure, gentle washing systems want the compound dirt to persist until water is sprayed to dissipate it.
The advantage of washing is that there is not so much pressure in a house, but it comes at the cost of water and more substances are used.
Is washing safe? Yes. Exactly like stress cleaning, however, should you not use the machine properly that can because you harm. High chemical concentrations can destroy vegetation and damage specific surfaces. Used appropriately, it is a safe way to wash.
