Drying time varies greatly by the type of carpet or fabric upholstery, the density/thickness of the pile, airflow around the area, and cleaning technique of the user. However, it is best to wait at least two to three hours before walking on the carpet after deep cleaning.
Some of our full-size upright machines include Express Mode - which can have carpets dry in as little as half an hour.
Note: The user is in control of the water output with BISSELL machines. Press the trigger to release water & formula, let go of the trigger to dry. Continuously holding down the trigger is not necessary.
