Query: Sparks.

We bought this Hover just over one year ago. Today it burnt up. Really, after smelling something hot, took off the hepa filter on the side. Turned on the motor to see what we could see. What we saw were plenty of sparks coming at us. Looks to be like the brushes on the motor went bad. It will cost as much to fix as we paid. Since it is just over one year old, and seeing how cheaply made this unit is made, we have learned our lesson. Hover has gone down hill.
