How Does The i-spraywash Cleaning System Compare To A Regular Foaming Gun?

What is a foaming gun, what sort of cleaning are they good for, and how does a conventional foaming gun compare with i-spraywash?

In this article, we are going to take a close look at how these two pieces of commercial cleaning equipment differ. We’ve also included a video to explain and demonstrate some of the differences between a conventional foamer and the i-spraywash cleaning system.

Is foam good for cleaning?

Yes. Applying a cleaning solution as foam rather than liquid improves the cleaning effectiveness by lengthening the dwell time on the surface. The foam clings to walls for longer so the detergent can work on surface soiling.

Foaming guns are good for cleaning large areas such as bathrooms, shower blocks, loading docks and kitchens. So a typical application would be cleaning toilets in a school, leisure centre or shopping centre, or the shower blocks on a mine site or commercial building.

Because foaming guns can quickly apply a large volume of water and chemical they save a lot of time. They are faster, simple and safer to use than alternatives such as throwing buckets of cleaning detergent around or using a pump up sprayer to apply cleaning solution. There is also less suspension of chemical particles in the air when using a foamer compared to spraying a liquid.

Let’s have a look at 2 types of foaming guns: What we will call a “conventional foaming gun” and i-teams i-spraywash system.

How conventional foaming guns work: You put whatever brand of liquid chemical you want in the chemical bottle, and as the water comes through the hose it is sucked up by a venturi valve and diluted with the water at a preset dilution rate, which then comes out the foaming nozzle at the front. When you want to rinse the foam off you disconnect the gun and squeeze the trigger to rinse. Some conventional foamers have a rinsing nozzle which can be connected to the gun to speed up the rinsing process.

Here is how i-spraywash works: A key difference is you use the i-spraywash tablets rather than liquid chemicals. You choose from 3 different i-spraywash cleaning tablets or 2 disinfectant tablets, put the tablet in the holder, set the dosage level on the adjustable dial, and the foam comes out the nozzle at the front. Like a conventional foaming gun, you disconnect the dosing part of the gun for rinsing, which is done with the rinse nozzle which can be adjusted for different spray patterns.

Note: You do not have to have a garden tap to use a foaming gun. You can use both types of foaming guns on virtually any bathroom tap using the Gardena Indoor Tap adaptor.

So how do these 2 foaming units compare? We are going to compare based on 3 key points: versatility, labour time, and safety & ergonomics.


If you are doing irregular cleaning of very dirty areas, you would be better with a conventional foaming gun as you can put undiluted chemicals in it to get a very strong dilution for heavy duty cleaning.

You can adjust the dosage on the i-spraywash gun; however, the i-spraywash tablets are relatively mild formulations designed for regular maintenance cleaning, not heavy duty cleaning. i-spraywash is not the best system for periodic heavy duty cleaning of harsh environments.

Mostly you would be using cold water for foam cleaning, however if you want to use a hot water don’t use i-spraywash as the tablets will dissolve very quickly. It will be good for whoever is selling you the tablets, but not good for your budget! Whereas with a conventional foamer (subject to the temperature that the gun itself is rated for) using hot water does not adjust the dilution rate.

So, thumbs up to the conventional foamer for versatility!

Cleaning speed

For regular cleaning, you will find the i-spraywash foaming gun is significantly faster than a conventional foamer as it has a wider spray pattern. The wide spray pattern allows you to clean at 1 sqm per second. In the video you can see a conventional foaming gun applying foam, compared to the i-spraywash.

There is a difference in the type of foam both guns spray. The conventional foamer sprays a thick body of foam, which tends to run down the wall faster and you end up with quite a large amount of foam on the floor. This can be hard to get down the drain when rinsing as this heavy, thick buildup of foam tends to sit on top of the drain. i-spraywash sprays a very fine bubble (called Active Foam) which is lightweight so tends to cling for longer on the wall where the chemical can do its work. And this finer foam makes it easier and faster to rinse down the drain.

Here is a video that shows the difference between the 2 types of foam in more detail:

These points are very important as labour is almost always the single greatest cost in a cleaning process. Reducing the labour time is often the fastest way to reduce the cost of cleaning.

As a side note, if you are cleaning faster, you are also using less water and having less environmental impact, as the tap flows at the same speed.

So hands down, this one goes to i-spraywash in the category of the speed of cleaning and reduction of labour cost.

Safety & ergonomics

On the safety and ergonomics side, i-spraywash is lighter than the conventional foamer at around 1KG vs 2-3 kgs. If you are only using it for 5-10 minutes a day it probably won’t bother you, but if you are cleaning for longer periods you will really start to notice the extra weight of a conventional foamer. You will carry a lot less weight over a year with the i-spraywash foamer.


With a conventional foaming gun, you manually measure the amount of detergent to use, whereas i-spraywash does this automatically based on the dosing level you set with the adjustor. i-spraywash eliminates the risk of a chemical spill or of the chemical wastage risk you have when manually diluting the chemicals into a conventional foamer.
