When we arrive we walk the area with a moisture meter and a thermal camera. Water moves under cabinets and inside wall cavities, so finding it matters as much as removing it. Then the truck-mounted extractor comes off the rig and we pull standing water out. For a typical residential job, the bulk of it is gone in the first couple of hours.
Drying is the longer part. We set air movers and commercial dehumidifiers sized to the cubic footage and the materials, because hardwood and carpet over plywood need different targets. Moisture readings get logged every day, so when your adjuster asks for documentation you have it. Most jobs run three to five days from arrival to passing dryness. Storm flooding or category 3 water takes longer because of the controlled demolition involved.
