Query: wasteful/uncleanable/harbors mold/takes a lot of time to maintain

The directions say to empty the tray and clean daily.You have to dump the water from the tray, take off the bottom, soak in vinegar or bleach waterThen put it back together.Mold still forms in the bottom and inside the unit and fan area that you cannot reach or get to.We also have a lot of minerals that are stuck in the machine and have made it a reddish tinge.Totally will NOT buy another one.NOT worth the trouble of not buying a filter.
