Hire a carpet shampoo service
Hire a carpet shapoo service, the kind that wets the carpet.
Make it a surprise for her. She will love you for it. (Send her to a spa for a day while the carpet dries.)
Next time you reload in the house, spread out an old shower curtain (buy one from a used goods store, don't use one from your house. Women are funny about that stuff.) If the waterproof cloth type that is ok. If the plastic type, lay an additional sheet over it (also from a used goods store)
Overkill, I know. But she will love you for it. It shows you care enough to do the overkill.
It's like the old adage: .50 BMG, when you care enough to send the very best.
Lost Sheep.
P.S. I use a Rainbow vacuum, which uses water as the filter medium. Whether a specific vacuum is safe to be inhaling flammable or explosive materials depends on the specife vacuum. Some suck the air in through the motors/fans and there is a chance for exposure to armature sparks. Some, (like the Kirby) have the motors completely sealed off from the vacuum air flow. So you/ve gotta examine your specific vacuum. Some women would LOVE to have you blow up their vacuum, assured that they will wind up with a new one. Other women really like their vacuum and would forgive you for risking it as much as you would forgive her for running your favorite sidearm through the dishwasher. Some women are touchy. All the other are just building up "anger points" for later use in arguments.
