Water Purification

The answer is all about achieving that flawless, professional finish! While tap water might seem clean, it’s full of dissolved minerals and impurities. When you’re cleaning surfaces like windows or solar panels, this water evaporates and leaves behind ugly spots and streaks. A water purification system is the ultimate solution to this problem! It uses advanced filtration, often a reverse osmosis system or a DI resin filter, to strip out virtually all of those total dissolved solids (TDS) from your source water.

Using pure water means that when it dries, it leaves absolutely nothing behind. Just a perfectly clean, spot-free surface. This is a total game-changer for window cleaners and exterior cleaning professionals. It eliminates the need for manual drying with a squeegee, saving you a massive amount of time and labour on every single job. You'll work faster, deliver better results, and look way more professional!

Choosing the right water purification system is a brilliant way to level up your cleaning game, and it really comes down to your local water quality and how much you'll use it. For most professional window and solar panel cleaners, there are two main types: Deionisation (DI) and Reverse Osmosis (RO). A DI-only system uses a special resin to strip minerals from the water. It’s super simple, lightweight, and perfect for areas with soft water (low Total Dissolved Solids, or TDS).

If you're working in an area with hard water (high TDS), a multi-stage Reverse Osmosis system is your best bet. These systems use a series of pre-filters and a powerful membrane to remove the bulk of impurities before a final DI polish. This makes your DI resin last much, much longer, saving you a heap of money on consumables in the long run. It’s the ultimate choice for high-volume, professional work. For either system, you'll need the right gear to deliver that pure water, so be sure to explore our top-quality Water Fed Poles.

Proper maintenance is the key to keeping your water purification system running like a dream and protecting your investment. The most important task is to regularly monitor your Total Dissolved Solids (TDS) levels. Using a digital TDS meter, you should check the water coming out of your system. Once the reading starts to climb above 10-15 ppm, you know it's time to change your filters. This ensures you are always producing pure water for that perfect spot-free finish.

For systems using DI resin, replacing the deionisation filter cartridge is a simple and quick job. If you have a multi-stage reverse osmosis system, you will also need to replace the carbon and sediment pre-filters on a regular schedule—usually every few months, depending on usage and your local water quality. Following these simple steps will ensure your system consistently removes all those minerals and impurities, giving you flawless results every time. To keep your system in top shape, you can find all the essential replacement filters and meters in our accessories and add ons section.

Choosing the right water purification system really boils down to two key things: the type of cleaning you do and the water quality in your service area. First, think about your main jobs. If you primarily clean windows and solar panels, achieving a spot-free rinse is your top priority, making a DI or RO/DI system essential. For general pressure cleaning on hard surfaces like concrete, pure water isn't as critical, but it can still help reduce spotting on certain facades.

Next, you need to know your local water hardness, or Total Dissolved Solids (TDS). You can check this easily with a simple TDS meter. If your water is soft (under 100-150 ppm), a straightforward Deionisation (DI) system is a fantastic, lightweight, and cost-effective option. However, if you're dealing with hard water (high TDS), a Reverse Osmosis system is the way to go. It does the heavy lifting to remove most minerals, making your DI resin last much longer and keeping your running costs down.
