This piece of junk began well enough, actually cleaning as well as larger, earlier models.  After 2 months, however, the plastic snaps block so the heap filter sits ajar and does nothing.  Update: the POS died after a year, and I had to replace it, having already gotten a big supply of the bags.  The switch of the REPLACEMENT failed in a month or so. I used the switch from the first to repair the second.  Here is what I learned. The Communist slave labor camp further cheapened the vacuum by replacing the older switch (labeled in one photo here) with a smaller, cheaper switch (shown in a second photo here).  A C-ring held the older switch.  Plastic clips THAT DO NO FIT THE SWITCH are supposed to hold the newer switch.  I settled for using museum putty to hold the replacement switch in.
