Just received and assembled the Hoover MAX Extract All-Terrain "steam" cleaner (actually a hot water cleaner) for both our hardwood and carpets (in prep for the deep clean in prep for Dad's memorial open house). I can totally see how it leaks for many/most users. Putting the cleaning solution tank into the rig is completely friction fit and not very foolproof. Have yet to actually supply it with water and try it, but I'm game. It doesn't look that hard.
