I know some of you will think im crazy, but I have TERRIBLE luck with Convertibles!! I know some of you can rebuild one with your eyes closed...but I always mess up something, same for a Dial a Matic...I have been trying to get a brushroll working in my Dial a Matic for a year or 2..disaster!!!!..I can take any canister apart blindfolded, but uprights in general drive me nuts!!!..the easiest motor to rebuild to me ,is a Constellation or Electrolux....the hardest..again, a Hoover upright, that bearing causes many curse words!!!!..LOLI would just once like to have a good working Convertible...I lke them..they just dont like me....the easiest upright to work on is a Royal....
