For users who only need cleaning foam on occasion, a low-cost foam machine might do the trick. A more affordable model does not need to have the same extensive features as a more expensive one. Cheaper models typically have less powerful pumps, smaller solution tanks, and fewer adjustable settings. Dishwashers can still perform basic cleaning tasks, like scrubbing outdoor furniture, pre-treating floors, or washing cars, with adequate amounts of foam. With the right research and selection, users will be able to fully clean their surfaces with little investment.
