The calculator applies illustrative per-square-foot rates by primary surface focus, scales with total washable area, adjusts for soil severity and access difficulty, optionally includes a hot-water or specialty-equipment uplift, and applies a regional labor multiplier. The total is split across detergents and supplies, labor and equipment time, and miscellaneous fees. Travel surcharges, HOAs, and commercial minimums are not itemized separately.
