They would have used this collector of dark particulate matter, but Nature abhors a vacuum ....
As an adult I have anxiety whenever I hear a vacuum cleaner running. It’s attributed to triggers formulated in my childhood. You see, whenever Mom was pissed off she would run the Electrolux. I was very attuned to the tension and how she would clamp her lips between her teeth in the “Mom is pissed off again” expression she has, banding the wand into every table leg and piece of furniture. It turns out she hated the Electrolux because it was so heavy, but she had to have it because that’s what her sister had.
10 years ago she finally got one of those 7lb Oreck XL units... but the damage is done. Just the sound of any vacuum cleaner triggers a flight response... like when I visit home and Dad gets out the vacuum and cleans aroundnthe litter box after scooping cat turds... oh, man, I have to go outside the house... weird but it is what it is.
