Before you start the buying process you need to figure what your planned applications will be. Will you be using your water blaster for domestic cleaning, commercial contract cleaning or industrial wash down work? Will you be pressure washing daily, weekly or only three times a year? What kind of work will you be doing, building maintenance, equipment wash down, vehicle washing, drain cleaning or clean up around the farm? Do you need to use hot water, cold water or have chemical injection options?
By figuring out what kind of cleaning work you’ll be doing, you’ll quickly get a good idea of the nature of the machine and accessories you need. You should at this stage know if you’ll need a domestic water blaster or an industrial one, you’ll also know whether it needs to be small and compact or large and trailer or van mounted.
There are 4 main types of water blasters. These are cold, hot, electric, and gas-powered (such as diesel or petrol types).
In this article, we’ve included only the electric and gas-powered water blasters… for a simple reason. They just tend to be more useful all-around as well as more powerful.
Cold Water Blasters
Cold water blasters are the simplest types as they only use pressurised cold water. This will do for quick washing and cleaning for lighter duties around the house, but little else.
On the bright side, they’re fairly inexpensive options for water blasters. They can send out a strong gush of water, though still not one as powerful or effective as their gas-powered or electric counterparts.
Hot Water Blasters
A hot water blaster would be good for a lot of casual home cleaning projects. This is because it removes bacteria and mould present on the area you are cleaning.
It also packs enough pressure to take away relatively tough grime, oil or dirt. You do have to be careful with these, though, because the hot water makes them a bit dangerous.
Electric Water Blasters
These types of water blasters are convenient and easy to tow and carry around. They have a mid-range pressure level that makes them ideal for home, car, furniture, and floor cleaning.
However an electric water blaster is limited by the reach of its cord. It’s also safer not to use extension cords as they can negatively affect the performance of your water blaster.
This blaster’s advantage over gas-powered pressure washers is that they don’t emit any pungent smoke and produce less noise.
Petrol or Diesel Water Blasters
In terms of pressure washing, these water blasters are the most powerful options. This makes them perfect for use on larger-scale washdowns for offices, construction areas, or factories.
Because they don’t use an electric cord, they are not limited in reach and area either. However, they’re definitely among the heaviest and hardest-to-carry blasters!

The Kärcher K4 premium has mixed reviews. Some love it, but some feel they didn’t get the value they expected in terms of the spray holder, pressure level, and plastic parts.
But those who did like it felt it was worth the cost because it was so easy to use and consistent. One owner said this:
“Used to blast off several years of accumulated grime from our decking without any issues.
I’ve borrowed other peoples pressure washers before and always found them to be very temperamental, especially if using quite a long water hose. Maybe only because its new, but no such problems with this model.
The hose storage options arent great if Im honest, but I can live it as this will only get occasional use in the garden.
I’m hoping the water cooled motor will prolong its lifespan. Buying on “Prime Day” I got this for a great price, so happy days.”
