Dry Vapor Steam vs. Standard Wet Extraction
Both methods are called "mattress cleaning." They are not remotely the same process, and the difference shows up in moisture and in what is left inside the foam afterwards.

Wet extraction is a good technology. On carpet, it is the standard for a reason: carpet fibers and a pad underneath can take a hot-water injection. A mattress is different. Its core is foam or fiber batting, and water that soaks into that core inside a closed bedroom is hard to get back out. The moisture you cannot see is the part that concerns us.
Dry vapor steam is superheated water vapor at very low moisture content. It carries the heat that breaks down oils, lifts soil out of textured quilting, and neutralizes organisms on contact, while leaving the foam core essentially dry. No chemical residue, no lingering damp.
We are honest about the trade-off: extraction can flush a large volume of liquid through heavily saturated padding in one pass, and for a mattress that has been flooded with a significant fluid volume, there are cases where an extraction step is genuinely useful. When we hit that situation we say so. What we will not do is make extraction the default on a sleep surface, because the default matters more than the exception.
For the standard case — dust accumulation, bed mites, dander, odors, a mattress that has never been professionally treated — dry vapor steam does the job with far less risk to the thing you sleep on. The comparison table on our home page lays out the specific differences field by field.
What do people ask about dry vapor steam vs. wet extraction?
Is dry vapor steam actually hot enough to matter?
The vapor is superheated at the nozzle and delivers heat to the surface. In published tests, a 96°C steam cleaner killed all of the bed mites (house dust mites) in treated carpet and mattress samples (Glass and Needham, 2004). Low moisture and calibrated passes protect the mattress; the temperature is not turned down.
Doesn't my mattress need water to get clean?
No. Water is a carrier. Heat plus mechanical passes plus extraction into microfiber is what actually removes soil and debris. Adding more water than necessary just leaves moisture inside foam.
My old mattress smells musty. Will steam fix that?
A musty smell can be a moisture and microbial problem in the upper layers, and attacking the source with dry heat helps more than adding water. If the odor is coming from a deep, long-term saturation, we will tell you honestly that the mattress may be past recovery and should be replaced.
