When you are filling the clean water tank on your machine, you will notice measurement lines on the back of the tank - one for water and one for formula (some formulas also have a measuring cap), to ensure you are using the correct amount of both. When cleaning large areas that require more than one tank, it is best practice to let the tank empty before refilling with fresh water and formula to ensure the mix is balanced to recommendations.
If your carpet cleaner has the "Express Mode", this will allow your carpets to dry in approx. 30 minutes. For other cleaning modes, or if your Upright Carpet Cleaner does not have "Express Mode", we would advise approximately 3-4 hours depending on weather conditions. To reduce drying time, open windows and doors if possible to improve ventilation.
