I recently bought a Vax Platinum carpet cleaner and used it for the first time last week. I used it to clean a small area of carpet in deep clean mode and it took 4 days to dry! The 1 hour mentioned on the Vax website is for the quick clean mode only and can't find anything about the drying time in deep clean mode. Wondering if it could be faulty. Could anyone who has one, advise how long the trying time is please?
