The 7 Best Water Blasters In New Zealand

Best Water Blasters New Zealand

A water blaster is a huge help in washing the outside of your house or your car thoroughly. If you’re looking for one, you’re in luck, as we’re listing the best water blasters in New Zealand today!

It can be difficult to make sure you buy the best water blaster, after all — particularly if you’re not quite sure what you should be looking for.

We’ve tried to make the task simpler by pre-selecting the best ones on the market. That way, you’ll be able to restrict your search to the highest-quality options from the start.

However, it still helps to know a little bit about how to choose the right water blaster for your needs. So, we’ll start with a quick review of what to consider, such as your purpose for the water blaster and the type you need.

After that, we’ll move on to the top water blasters in New Zealand.

Purpose of Cleaning


Before you buy a water blaster, you should first think about where you will use it. This will do a lot to narrow down your choices later on.

Are you going to use it to clean your walls, driveways, shed, patio, or deck? Or to do some heavy-duty jobs like construction space cleaning?

Then, you have to consider the frequency of your intended use. Are you going to clean daily, weekly, or twice or thrice a year?

List your answers to these questions so you can refer to them easily later on. Now, we’ll guide you through the different types of blasters available to make your choice even easier.

Types of Water Blasters


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!

Customer Reviews

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.”

Safety Tips

As a final note, we’ll just remind you of some safety tips to apply to whatever water blaster you do decide to buy.

The first thing to note about water blasters is that they have a pressure level that breaks through wood or hard surfaces. In other words, they can be dangerous if you’re not careful with them.

Always be mindful of where you’re aiming your blaster. Try to avoid using it too if there are others in the vicinity who may cross your path.

Anyway, here are some more safety tips when using your water blaster:

  • Before using a pressure washer, always keep an eye out for people, pets, objects, glass, or any unpredictability.
  • Protect yourself at all times by wearing safety goggles, earmuffs, gloves and boots.
  • Always turn it off when not in use.
  • Never use an extension cord because it can decrease the performance of the water blaster.
  • Be careful not to spray appliances, power outlets or cords. Steer clear of all forms of electricity.
  • Don’t use ladders, instead work up your pressure washer to reach a certain height.
  • Only use gas-powered water blasters outdoors and where there’s a good amount of ventilation.
  • Above all, be safe and careful every time you use it.

And with this, we conclude our list of the best water blasters in New Zealand as of the moment! Any of the ones we’ve listed above should be capable of tackling most jobs.
