My Dirt Devil is in my utility center on our new rig. It easy to access the cover and replace the bag. However, after changing the bag and installing the cover the housing would fall in behind the utility center making it impossible to reinstall the cover (the cover is larger than the hole in the utility center). After investigating a bit, it appears that PI installed
ONE small lightweight tin-type corner bracket which is quite flimsy. See pix. I corrected this by installing
FOUR metal corner brackets which is clearly overkill. But it would be nice to see at least 2 installed on assembly. It's a bit difficult to access that area in behind the Dirt Devil, so I wasn't taking any chances!!! Now the vacuum housing is snug as a bug in a rug!

Hope this helps someone else. rockin'
