If you've got a suction problem when not using the hose, try cleaning the lint filter that is either located on the bottom of the steamer (it is red) or under a clear triangular piece of plastic on the top of the nozzle housing. This should bring your suction back.
The hole in the hose will only affect the suction when the handle is in the upright position and you are using the hose. If you use the hose a lot, you might want to take it in to a repair shop and have it replaced. If you don't use it that often, duct tape works well.
