Using this floor tool is easy. First, make sure your vacuum cleaner is turned off. Then, simply insert the tool into the hose pipe. The 31.2mm external diameter ensures a snug fit. When using it on hard floors, move the tool slowly and steadily to pick up dirt and debris effectively. As for maintenance, after each use, remove any large debris from the tool. You can wash it with mild soapy water and let it dry completely before storing. Keep in mind that while it may fit some Bosch models, always double - check compatibility.
