Just a big general purpose. larger than the hoses, "canvass" bag. Also keep brushes, hand tools, upholstery tool, cloths, furniture pads and skiddies in it as well. Easy to bring all into house in one go. Just remember when coiling hoses ( always keep solution and vac separate) to make sure the vac hose is completely empty-don't want to flick waste water all over the wallpaper/furniture etc as I am coiling it.
