My answer to this question has been materially affected by sites such as Meh… If acquiring a vacuum cleaner required going to a store to buy one, I’d probably have just one. But because of all of the damn vacuum cleaner “deals” on the Mehs and Woots of the internets…
A roomba that I bought from woot. . . but my current place doesn’t really work for it, so I let the battery get too low and now it doesn’t run at all. I guess that counts as .3, if I extend @narfcake’s fractional system a bit.
I have a carpet cleaner as well which does have a “vacuum” like portion that sucks up the soapy and rinse water used for cleaning the carpet, thus I would count it as a 0.4 vacuum, bringing my houses total to 1.4. Unless you count a dog which will suck up most any food items that gets dropped, that would be about a 0.16, this would then bring my grand total to 1.56 vacuums.
When I originally saw this, I was like “why would anyone have more than one vacuum cleaner? Maybe some people have an ‘upstairs’ vacuum so they don’t have to lug it when it just calls for spot duty?” Then I realized that in addition to my one “regular” vacuum, I do have a shop vac and a dust buster, so I guess that puts me right on the average.
@bocoroth our old vacuum forming machine had a unit that strongly resembled an old industrial Electrolux mounted to its frame. I offer wondered if we should ever open it up and look for/change/empty the bag inside.
-Dyson for basement (heavy cat litter traffic areas)
-Shark for upstairs (hard floor and carpet)
-Shop Vac (for shop)
-Corded handheld thing for carpet stairs and car interiors
-Rechargeable hand-held thing (very light duty, probably should trash this one)
-USB keyboard vacuum (doesn’t suck enough)
-Roomba from kickstarter fuku (no longer used because battery started to suck)
