Machine Tank Fill Calculator

How many tank fills an auto scrubber or extractor needs for a floor, the concentrate dose for each fill, and the chemical cost.

Inputs

Range: 1–100 gal

Enter the measured quantity in the unit shown.

Range: 1–1,000,000

Length times width of the area to be cleaned.

Range: 50–20,000 sq ft per gallon

From the product label or technical data sheet. 1000 sq ft per gallon is typical for a spray, 2000 to 4000 for a mop and scrub.

Range: 1–512

The number after the colon on the product label.

Check the label wording. "1:64 solution" and "1 oz per 64 oz of water" do not mean the same thing.

Range: 0–1,000,000 per gallon

Enter the current purchase price in US dollars for the unit shown.

Reading: what this result means for the job
One tank covers this floor at the rate entered. Write the concentrate dose on the machine so a relief operator mixes the same strength, and keep the solution tank distinct from the recovery tank when recording the fill.
Applicability limit
The EPA-registered label governs. Using a registered antimicrobial inconsistently with its labeling is unlawful under 7 U.S.C. 136j(a)(2)(G), and 40 CFR 156.10(i)(2)(ii) requires every label to carry that statement. This tool does arithmetic; it does not approve a dilution, and it does not determine compliance. Tank fills follow the tank capacity and the application rate entered, and both move with machine speed, brush pressure and solution flow. The figure is the solution that leaves the tank, not the solution that reaches the floor after the squeegee. This is a planning figure for the values entered, not a measured result. Coverage rates, product yields and application rates are properties of a specific product, applicator and substrate, and the label or data sheet for the product you are using always takes precedence over the default here.

What to check

  • Take the solution tank capacity from the operator manual, not from a sales sheet.
  • Confirm the dosing figure against the label before writing it on the machine.
  • Keep the solution tank distinct from the recovery tank and the battery watering tank when recording fills.

Tank fills come from your tank capacity and application rate, and both change with machine speed, brush pressure and solution flow. The dose per tank is the figure to write on the machine so a relief operator mixes the same strength.
