Well that was a waste of a perfectly good 45 minutes.
Surely I won't stick around for more.

you have to understand, it is really hot outside, therefore, I closed all the windows to keep the warmth outside, and have a closed system.
Not the only things heating up my system are the fridge, my computer and me.
When I use my vacuum cleaner, some of the energy intake will be absorbed as heat, and heat up my system.
So the decision on vacuum cleaning or not is rather tough.
