What is the difference in the 32oz sprayer and the Foamer?
The difference is the 32 oz size does not foam and is more of a trial/travel size. It does a great job in cleaning but does not produce the foaming action and does not have a quick disconnect feature. The Applicator/Foamer is a professional grade foamer and sprayer. It has a nozzle/sprayer that attaches to the hose with a quick disconnect. The reservoir (bottle) is separate so you can pour your product into the bottle, quick connect it to the attachment on your hose and rinse. It saves you a tremendous amount of time, where the 32oz size does not quick disconnect. If you can go to the home page and download the demo, it will give you a better understanding of how it will save you a great deal of time and money.
