i turn it on,it emits this stink like warm spoiled cheese. i never used it for anything other than my carpet,and i never used it to clean anything wet. and the machine isn't even a year old yet. i purchased it brand new.
You need to change the bag and filters if it has a dirt cup. Other wise you need to use best quality vacuum cleaners...... :)
Cleaning the hose i detach it from the machine and provided that it's not a current carrying hose what i do is a partially fill the hose with warm water and dish soap then i move the ends up and down to swish the water through the hose be sure to rinse it out with water and then if you can blow it out or hang it up and do not use it till it's dry
Change the bag, if it has one, or wash out the dirt cup and hose if it has a dirt cup. Change any filters.
