it depends on the make of the kirby you are using but most kirby systems come with a portable shampooer and special shampoo. I would not recommend using your zip brush for shampooing purposes, the zippbrush is designed to loosen up dog hair, dirt, ect. when vacuuming.
to shampoo upholstery do the following:
remove bag from side of machine,
place hose where bag goes,
remove power head from front of the machine,
place air intake valve on front of machine where power head was (intake valve kinda shaped like a pig nose with small holes on end)
attach portable shapooer to end of hose and fill with water and kirby shampoo
spray shampoo witch is foamy looking on whatever you are shampooing, rub into fabric w/a brush and let sit till dry.
when dry turn kirby back into a hand held vacuum by putting powerhead back on front of machine and putting bag back on side of machine, then vacuum furiture. (make sure it is 100% dry before you vacuum because Kirby is not a wet vac!)
Hope this helped ya out a little
You are referring to the green led light on the front of the machine that tells you the brush is rotating? this is operated by a small magnet on the brush roll, when rotating it generates a small current to bring the light on. Remove the brush roll and check for damage behind the green led inside the case, also check for the magnet on the brush roll, ensure it is not missing and the brush roll is in the correct way round, magnet needs to be at green led end (ie to the left) Magnet is fitted flush within the brush roll close one end and is around 6mm 1/4" diameter. Green light not working will not affect the machine in any way.
