Hi, I use a Puzzi brand cleaner. Nothing special they look like an Electrolux pull a long vacuum. Tank in the back, collects dirty water in front easy to use. I bought 2 used machines a few years ago to replace plasticky commercial Bissell machines. I use Milestone Hotline chemical and it all works well. But nothing works as well a true high powered suction machine such as the pro's use. Got suck out the grit and dirt !
