Using this vacuum scent and fragrance is easy! All you have to do is drop 1 or 2 tablespoons into a newly installed vacuum bag, and you'll be good to go! Alternatively, you can also just vacuum up the fragrance!
I haven't had to change the bag in my vacuum yet, but it appears to be easy enough and I like the fact that the hose end to the vacuum unit does not have to be removed in order to change the bag. This is another reason why I don't like the ProLux Terra Vacuum, very hard to replace the bag.
