Spray-and-vac Cleaning

Spray-and-vac cleaning is a “no-touch” method - cleaning is accomplished without the need for workers to touch soiled surfaces with their hands - used in professional cleaning in which a pressurized, diluted cleaning solution is applied to soiled or contaminated surfaces. Using the same machine, the area is then rinsed; this is typically followed by vacuum suctioning that removes the applied liquid along with the suspended solids and dissolved contaminants that have been removed from the surface.

A key advantage of this method over traditional approaches is the ability to deep clean grouted areas (e.g., wall, counter and floor tile) preventing buildup of soil and bacteria in grout lines. Application of a cleaning solution followed by pressurized rinsing and vacuuming removes soil more effectively than methods that rely solely on absorbent wiping (e.g., mopping, microfiber and cleaning cloth use). In addition, studies published by ISSA, the largest cleaning association in the world, have found that compared to legacy methods these systems potentially reduce cleaning times by 1/3 or more.

Unlike outdoor pressure washers with application pressures of 1,000 - 5,000 psi, spray-and-vac units are designed for long-term indoor use on grout and other surfaces, and offer variable application pressures ranging from 110 – 500 psi.
