If I could return this vacuum, I would.  It is absolutely terrible.  If you have pets, avoid this vacuum.  It clogs every time I vacuum and has to be unclogged.  It doesn't even get full and you have to take a stick and unclog it.   The design is such that the inlet is narrow and facilitates a propensity of clogging.  It does not pick up cat litter and leaves a trail.  The only thing going for this vacuum is that it has good battery life.  Other than that, it is completely useless.
