Hi i have sunsun question. I just got mine and I was following the post and lubing it up and stuff and I think it leaked some kind of lubricant on our floor. this seemed odd to me but it smells kind of like wd40 but with the feel of an oil. Are these things lubricated in such a manner. Does anyone know if it is possible for this to happen. I think it may be something else but I want to rule this out. Also, it runs well but I loose suction and have to re-prime after a few hours any ideas on this as well? thank you for your help.
