Very good foam sprayer, with exceptionally rich foam.
Together with AutoGlym Power Blast-phase 1 & Power Wash-phase 2, you can clean the car in half the time and with much less scrubbing.

Inside the box, it has the container, the lid with the sprayer and the tube, and an adapter for Karcher pressure washers with a lance that accepts QuickConnect. It does not come fully assembled but it is not difficult to put together. The container holds 800ml and has a measuring scale on its side.

It has two adjusters, the top cap which controls how much soap it draws, and the front nozzle which controls how the soap is sprayed, from fan to straight.

I was quite satisfied for about 1 year. I used it with Auto Glum Power Blast and the foam it produced was flawless. Unfortunately, it started to leak water from the black plastic connector that attaches to the pressure washer and is now useless as it cannot be replaced.

Top frother, with an integrated selector so you can choose the density of the foam you want. In combination with the polar blast liquid from the same company, you get top results

Very good. No comparison with the karcher mother I used until now.
You also save on soap.
As a construction it looks sturdy and has a large base so it is not in danger of tipping over.

It is a pretty good foam gun.
It created a particularly rich and stable foam on the car using Autoglym's Polar Blast and Polar Wash, and with the setting on maximum.
It would be good to "close" the nozzle in front to spread the foam.
Also, pay attention to how much you "open" the top valve.
If for some reason you don't want a lot of foam, turn the valve less than half a turn.
Then it starts sending almost plain water.
It requires calm and not hasty movements because it can come loose.
An important drawback is that there is no liquid meter on the bottle.
Also, as soon as you get it and want to use it with a Karcher machine (the adapter is already included),
make sure to test it on the pressure washer gun because there is a possibility that it may not attach correctly.

At first, I was quite satisfied until after 5 months of use, the container wouldn't screw on properly and kept falling off when I tried to work with it because it wasn't tightening correctly.. such a waste of money

Quality construction. In combination with the products of the Polar series, the result is impeccable compared to the corresponding ones of Karcher. It is used with the Karcher K7 pressure washer.

A mediocre quality construction - a tool for its price always.
I use it on the Karcher Compact K4 3-4 times a month and wash 20-30 cars each time.

The plastic parts are of low quality, I doubt if it will withstand long-term use...
For example, the adapter for Karcher has already started to acquire "wear and tear"... from the weight.
Also, even though I adjust it differently from other foamers, it seems to consume a lot more material, I don't know why this happens.
Its advantages are that you can adjust the "front" on how the nozzle sprays.
The product is recommended only for amateur use.

It neither cries nor laughs, as the common people say.
If you want foam and effectiveness, the "solution" will play a role. Then even the simplest Karcher foamer will do the job.
Regardless, it deserves 3 stars. Only.

Perfect foam maker! With the first try, it made fantastic foam! You actually get what you pay for in the end

Good foam maker but very expensive and I think there are now equally good options at a much lower price. An example is shown in the following video.

Unfortunately, although it is one of the best on the market, I have changed it twice. I don't know if I'm doing something wrong, but suddenly it doesn't have pressure as if it's clogged, even though I always clean it and use it on a Karcher K3.

Very good foamer. It does its job as it should. I use it with the polar blast, polar wash, polar seal trio in the recommended proportions. PROBLEM. After the tenth use, the plastic adapter that attaches to the Karcher K7 pressure washer broke. I sent an email through the contact form to Autoglym Greece to ask them how to get a new adapter, but I haven't received a response yet, one month later. (Thank you very much Autoglym!!! You just lost a customer) 5 stars for the foamer and the trio, and 0 stars for Autoglym gr's customer service.

Honestly, I'm telling you as expensive as it may seem, GET it!!! I use it together with the active foam from autoglym and the result is the creation of a foam so dense that it feels like shaving foam!!!... What others write in their reviews about how good this foamer is, is true!!!...

Sturdy construction, large 1lt container, adapter for Karcher pressure washers. Used for washing car with Parkside 170 bar pressure washer, with the appropriate adapter. Perfect in use, rich foam (for starters I tried the active foam from K2), easy cleaning. Ratio 1:5 active foam-water, resulting in rich thick foam with the top rotary switch closed. I highly recommend it!

Amazing foam cannon, the best on the market, very sturdy and made of good materials. The feeling is that as soon as you hold it in your hands, you know it's a professional one. And with the appropriate shampoo (auto glym) that I bought, the foam cannon goes to another level!!! No more demanding scrubbing... Simplicity, Flexibility, Durability!!! It fits all pressure washers from 160 bar and above and it even includes its own adapter!!!

When we talk about a foam gun, we mean this one. Quality construction and sturdy.
I use it to wash an SUV with POLAR BLAST shampoo and it does amazing things.
It leaves a thick layer of foam that doesn't want to dissolve. WE'RE TALKING ABOUT FOAM!!!
The mixture doesn't run out immediately. I make at least 4 good passes.
I don't even have the most powerful pressure washer, I have a KARCHER K2 Classic, BUT it combines exceptionally well.
The packaging also includes an adapter for KARCHER.

If I could find a negligible negative in my opinion, it would be its weight.
But I don't consider it at all because I don't use it for more than 10 minutes during washing.

Snow machine, with convincing nilfisk 190 bar and the appropriate adapter throws out a lot of foam. Using the polar blast liquid it produces a LOT of foam and VERY DENSE as well as the polar wash also produces a lot of foam (less dense compared to the blast) and stays on the car for a long time without being waxed

Very good foam sprayer in combination with a 160 bar pressure washer, Annovi Revieni brand. The foam is very thick when turned to full, I wash the car and the foam stays on the road for a day and a half, the soap is polarblast. For use, definitely in a shady place and if the vehicle is very dirty, it will need scrubbing with the soap.

Good foam cannon, works perfectly with polar blast and creates rich foam! It comes with a connector for karcher k series pressure washer! If you want something better, go straight to mtm which, however, costs twice as much! At this price, it is one of the best!
