Input:
I love the eureka mighty might cleaner as this is my second one.  However, when this one arrived, there was no floor cleaner brush in the box or any instruction booklet.  The box came sealed and in good shape so I am assuming it was not put in the box at the factory.  I do not want to return the whole cleaner as I still have the brush from the old cleaner that does not work.  Not sure how to ask for the missing floor brush, as the only option seems to be to return the cleaner.
