If you have to remove glued-down bamboo flooring, hope it was installed by an amateur. If it was, it's likely that there wasn't enough adhesive or the right kind used. If the flooring was installed by professionals, you might have a removal nightmare on your hands. The type of bamboo flooring, whether board length or tile, along with the type of adhesive used, determine how long it will take to tear it out.
Set the blade of your circular saw to the depth of the flooring and make a cut about 15 inches away from the wall across the room, preferably in a seam.
Make another cut in another seam and then make perpendicular cuts about 12 inches apart across the lines. You are dividing the flooring into sections. This is important if your bamboo flooring is not tile.
Use a 3-pound mini-sledge and a pry bar to remove each section. Insert the pry bar under the tongue side (if there is one) of the flooring and hit it with the hammer. This should either pop up the board or help you start ripping it out.
Use a heat gun very carefully on the glue underneath the boards. You will likely need help to do this. Have one person pull the bamboo up with the pry bar while you heat up the glue with the heat gun. This will enable you to get your pry bar farther under the wood and make prying the wood up easier. Be careful not to burn yourself or the wood with this method.
Push a simple hand scraper -- a metal scraper on a pole -- around on the floor to remove the remaining glue and wood from the floor.
