Hands down higher temperatures in water clean better than cold. If you want a good cleaning job done on your patio or garage then you should consider investing in a hot water pressure system. The clean that you get from these types of systems is much better overall than investing in a cold water system. Also if you have greasy surfaces and surfaces that collect a lot of grime and germs a hot water pressure washing system will get the job done a lot more effectively.
Many commercial cleaners or home type systems come with attachments that you can use such as for steam cleaning surfaces that don’t require as much pressure but still need to be disinfected and cleaned. The best option for cleaning gutters and removing leaves from your home is with a high temperature pressure system.
If you are looking into investing in one of these units you will note that for the higher temperature unit you will pay a little more over the cold water unit but the extra investment will be well worth the money for the type of clean that you can get. These systems are more highly favorable for tougher jobs and will cost you less in cleaning bills over the long run say if you hired someone to do it professionally. High temperature wash systems are also great at disinfecting surfaces and this makes for a cleaner environment.
You will find that you do not have to use as many or any cleaning agents with the higher temperature washer because the hot water itself acts as a disinfecting agent in itself, killing germs on surfaces and removing dirt all at the same time. It is overall more efficient than the cold water systems.
It can also be more effective in cleaning your home’s surface if you are looking at getting a paint job. The hot water will remove any old chipped paint and grime easier and will leave the surface smooth and clean. Either way you will get a better cleaning system from the hot water cleaner versus the cold water counterpart and over time this will save you money.
