Yes · it connects to a standard garden hose and mixes soap at a selectable ratio (1·12 oz per gallon). owners specifically use it with car wash shampoos including Chemical Guys and Meguiar's Gold Class. It produces foamier output than a plain hose-end sprayer, though lighter than a pressure-washer foam cannon.

The quick-set dial selects how much concentrated soap is mixed into each gallon of water passing through the unit · settings range from 1 oz/gal (light dilution) to 12 oz/gal (heavy concentration). The listing states the device uses 4 oz of chemical per gallon at a default setting.

The Foamaster II uses a standard 3/4" garden-hose thread (GHT) and attaches to most standard US garden hoses. The listing confirms compatibility with 'most standard garden hoses.'

No · a pressure-washer foam cannon produces significantly denser foam at high pressure.

It is a step up from a soap-mixed hose-end sprayer, but physics separates it from pressure-washer output.
