Always wanted to use a foam cannon to help wash my car. This one works pretty good. My pressure washer already had a quick disconnect adapter on it, some don't (its not included). Foams up good, but I try soap that works better with foam blasters.
I already own another foam cannon but thought I would get another as a backup for when washing two cars so I wouldn’t need to stop and refill the bottle. The main difference between this model and others I have purchased is that the bottle isn’t translucent however you can still easily see the contents and know how many ounces you have put into it. There are so many claims that some bottles are better than others, some brands have “air injection technology” and some break after the first use. From my own experience I will say all the bottles I have used seem to perform about the same. There are key factors though that will tell you what to expect. The main thing to look for are that the two blades at the outlet are both flat and meet perfect.
