Ohhhh... ok. I didn't know they made mobile models as well. The only Kirbys (Kirbies?) I'd heard of were these THINGS that you built into the actual house.
The machinery would apparently sit in the basement (or similar) and rather than drag the vac from room to room, you'd simply plug the hose into a wall (think "powerpoints that suck") and start cleaning.
Kramer: You're thinking of a "Central Vac". Kirby may have made those also, but most are a Sears item from days gone by. THose things rules as long as you're not trying to vacuum your car without a really long hose. Our family Kirby is about a quarter century old, weighs about as much as an SVT-810, and sucks with the best of them. Am happy to report that after a proper drying out our Kirby works well (needs a new bag...) and might actually last another quarter century.
The odd chore I was doing was not related to chinking; I use silicone acrylate caulk for that these days. Long winded, but: I had installed (with MUCH help) a couple of steel I-beams which allowed me to remove a couple of support posts that just got in the way. One end of the new I-beam rests on the top of an interior corner log wall that is a common wall to the bathroom. The law of unintended consequences caused the extra weight to compress the log wall a bit more than anticipated which made the bathroom door stick, so I hammered in cedar shake wedges to lift that corner up just a little bit. Worked like a charm. Trimming the cedar shims created a mess, and the log walls were a bit of a mess anyway from the hords of cobwebs that are part and parcel of owning a log home. I'm telling you, home ownership is for the birds. Live with your parents as long as you possibly can. Be like Fonzi and find an apartment above some old bird's garage.
