The Foamtec30 medium-size cleaning model works with Santoemma's patented Foamtec system to clean and sanitize public restrooms through a process of spraying foam, rinsing and then vacuuming. There are four stages to the cleaning process. First a chemical solution is sprayed on all surfaces that need cleaned and a chemical action takes place. Then the solution is rinsed with clean water and residual liquid on the floor is vacuumed up.
