In general, I’m a fan of carpet. It’s soft and warm underfoot, it keeps would-be dust bunnies trapped in one place instead of floating freestyle onto your furniture, and you hardly ever get mysterious dirt granules stuck to your bare feet while walking on carpet. The problem with carpet, though, and it’s a big one, is that it always ends up filthy because you can’t just wipe away grubby footprints and cat hairballs and spilled juice. Carpet cleaning seems to always turn into a full-fledged ordeal involving a noisy machine and mysterious soap that leaves behind a filmy residue: the carpet extractor.
