Except during startup, more than a 3v drop in the basement voltage may indicate a bad connection upstream of both the basement and the vacuum's outlet. If other lights get brighter it's a bad neutral connection.

I opened your link but I didn't find your post.
There is an MDShunk on the site you cited. You wouldn't know if he is the same MDShunk that sued his high school for the right to pass out Creationism literature, would you?

My guess is that your basement lights are on the same circuit as the plug you're using upstairs, to say it simply. When you turn your vacuum on, the motor takes a lot of juice to get going, and that drains the power on your lights which are downstream in the circuit.

If dimmed breifly during the vaccum start up it is normal but stay dimmed during running mode then no you have issue you may have loose connection somewhere along the circuit.

Most vaccum I know they will draw about 7 to 12 amp range depending on how big and fancy it is.

with 15 amp circuit it pretty close to trip the breaker if it only load but if you have other loads on that circuit then yeah it will be matter of time before the breaker trip.

Merci,Marc
