I have a kirby G6 and it will only run with the attachments on. When I put the front of it on to run it over carpets or to scrub carpets it wont turn on.
check the front of vacuum there should small button there it stops motor running you need to check fitting you use it should have tab on it to fit switch wont work with out it check its not broken off [you can check motor push switch with pen tip when turned on should run if ok
