I first vacuum as best as possible, both sides.
Then it's up on my tower, then use the air compressor with a small nozzle to blow the crud out prior to soaking, scrub, rinse and extract, then back up on the tower to dry.
Pull down when dry, groom, roll-up, tie and deliver.
I have a real #^%$$ of a rug, 10 x 8 foot, heavy as when dry, very testing when wet.
I've done it three times now for an elderly, incontinent couple.
NO MORE !!!
Crikey, I'm nearly as old as they are.
