“Steam cleaning” and “deep cleaning” usually mean the same thing in everyday conversation, but professionally they describe different methods. Here’s how to think about it.
Hot-water extraction (steam cleaning)
Hot-water extraction injects a heated cleaning solution into the carpet under pressure, then immediately extracts the water along with dirt, allergens, and bacteria. It’s the most common deep-cleaning method for residential carpet and works well for pets, allergies, and visible soiling. Drying time is typically 4–8 hours.
Encapsulation
A polymer is brushed into the carpet, surrounding dirt particles. Once dry, the polymer crystallizes around the dirt and is vacuumed up. It’s low-moisture and dries fast, but doesn’t remove as much trapped soil as extraction. Common in commercial maintenance.
Bonnet cleaning
A spinning absorbent pad scrubs the carpet surface. Fast and inexpensive, but mostly cosmetic. Best for hotel hallways and other large commercial spaces between deep cleanings.
Which one should you ask for?
For most homes, hot-water extraction is the right answer. For office or retail spaces that need to be back in service quickly, encapsulation is often a better fit. When you submit a quote request, mention the carpet type and whether you have pets — the provider will recommend the best method.
