I was excited to get this machine after reading reviews. However after 4 uses, going thru all the help tips AND taking it to a service center, it still won't suction water from the floor unit. I get maybe 1/3 of the water put down. The hose unit works great. So good I couldn't believe how dirty the floor unit left my carpet. I don't know where to go from here. I have emailed and awaiting answer. This is a lot of money to not have a machine that doesn't works. Can't imagine doing a 16x20 room on my knees with the hose unit. HELP
