It's a sad day.
My vacuum is sick.
When you push the vacuum forward, everything's dandy. But when you pull it backward, the wand separates from the carpet head just ever so slightly, so the electrical connection breaks and the power to the brush in the carpet head is broken and while there's still suction, the roller brush does not turn and the light goes out.
It makes me weep.
I need to take it in to be serviced - they said it just needs a new electrical thingybob - but guess what? If you duct tape the wand to the carpet head, it doesn't separate when you pull backward.
But now my poor vacuum looks trashy. I'll take in after the first of the year. I mean it.
