Interview Questions for Vapor Cleaning

Vapor cleaning, also known as steam cleaning, uses superheated water vapor to clean various surfaces. Unlike traditional cleaning methods that rely heavily on chemical detergents, vapor cleaning primarily leverages the power of high-temperature steam to loosen and remove dirt, grime, and grease. Traditional methods often involve scrubbing with detergents and water, sometimes requiring multiple passes. This can be more labor-intensive, potentially use more water, and leave behind chemical residue. Vapor cleaning, in contrast, is often faster, more environmentally friendly (depending on the cleaning solution used), and leaves surfaces drier.

Think of it like this: traditional cleaning is like scrubbing a stubborn stain with soap and water – it requires effort and might not always remove the stain completely. Vapor cleaning is like using a powerful jet of hot steam to blast away the stain – it’s more efficient and often leads to a deeper clean.

I’m familiar with a range of vapor cleaning equipment, from small, handheld steam cleaners ideal for spot cleaning to large, industrial-grade machines used for commercial applications. These can be broadly categorized as:
