How long will it take for my carpet to dry after it has been cleaned?

This is a difficult question to answer given that every home is different.
In winter, it is advisable to assist with drying by turning on heating or if the weather allows, opening windows or turning on ceiling fans to aid evaporation.
In summer, the weather usually allows for opening of windows and doors to allow a good airflow to aid the drying process.
