The small Foamtec15 cleaning model works with Santoemma's patented Foamtec system to clean and sanitize public restrooms by spraying foam, rinsing, and vacuuming. It works best in small places and cleans using four stages. First a chemical solution is sprayed on all surfaces that need cleaned. Then a chemical action takes place, and then the solution is rinsed away with clean water. Residual liquid is then vacuumed from the floor.
