Water Blaster Buyer’s Guide

If you’re looking to purchase a water blaster, then this article is for you. There are many different factors that go into buying the perfect water blaster. Do you want one with high pressure? How about one with good distance? What size would be best suited for your needs? We’ll answer all of these questions and more in our buyer’s guide!

What type of water blaster suits your needs?

Electric (corded)

The mains electric water blaster is great because the pressure can be adjusted. This is not an issue for low-pressure households, but if you live in a high-pressure household then it could be an issue.

The downside to this type of blaster is that it’s more expensive than battery operated blasters. It also requires an outdoor hose or tap which will need to be plugged into electricity as well.


Petrol-powered water blasters are a good choice if you want pressure and distance. There’s also no need to worry about running out of battery power as these can run for hours before needing to be refilled.

The downside is that they’re incredibly loud! This could be an issue in close quarters or if noise restrictions are in place. 

Battery-powered (Cordless)

If you want a water blaster that’s portable or lightweight then this is the type of blaster to get. You can choose from corded and rechargeable battery powered blasters, but keep in mind that they’re not as powerful as petrol or electric ones. Rechargeable batteries are also expensive compared to other types of batteries so it may be better just to buy one with replaceable batteries instead.

What is the cleaning power of the water blaster?

Not all tanks are created equally! Some tanks will allow the blaster to produce larger droplets while others may spray cleaner further away from the face by producing finer mist jets.

These types of tank typically come on foam cannons with adjustable distance settings. This allows users to adjust the width of spray to clean hard to reach places.

How much water does the blaster use?

Some water blasters will use a small amount of water while others may consume more than you would like. If you’re using it for cleaning then it’s important to consider how much cleaner or disinfectant is required per litre compared with the capacity of your blaster.

If you want to save money and protect the environment, opt for an eco-friendly blaster instead! These typically come with larger tanks so they’ll last longer and require less refills between uses.

What type of nozzle does the water blaster have?

The tip determines what types of surfaces can be cleaned by adding different attachments such as brushes, disks, etc. depending on its specific purpose (e.g., cars/boats vs por). So make sure that if you’re buying a water blaster for outdoor use, you check if the nozzle is adjustable because this will be important when cleaning different surfaces.

How long can the water blaster go in between refills?

If your tank is small then it may only last 15-20 minutes before needing to be refilled again. When choosing what type of water blaster to get also consider how much time you have available each day to refill the tank or charge the battery.

Battery power usually varies from 30 min up to an hour depending on whether or not its cordless and rechargeable/replaceable batteries instead of built-in ones. If possible try out different types of blasters with similar specs so that you know exactly what fits your schedule!

Where are you going to be using your water blaster?

Water blasters can be used indoors and outdoors. For example, they’re great for cleaning cars because the pressure of water allows dirt to come off easily with no chemicals or detergents required. If you like camping then a battery powered blaster is ideal as it doesn’t require electricity and provides hours of use before needing to recharge!
