Re: Kirby G4

Take off the noozle, take off the bottom plate and remove the brush roll and old belt. Check the brush roll while you have it off to make sure the end spin freely. Put the belt on the brus roll and re-install in the noozle, put on the bottom plate. Then turn the big knob on the front of the nozzle all the way, you can only turn it so that the belt catches and will stretch, it will stop when you are all of the way, then re-install the nozzle back onto the Vac, turn that knob back the other way and you are all done.

The green light is not coming on and kirby is not sucking

HI There,

When the green lights do not come on when vacuuming with a Kirby, this indicates that your belt has either broken or fallen off. There is a magnet on the beater bar that activates the LED green light when it's spinning.

Here's a helpful video tutorial that we recorded, that will show you how to replace the belt, as well as perform basic maintenance on your roller brush to prolong the life of your belt as long as possible.
