A handheld vacuum cleaner is a tool that you must need someday in your home. The handheld units provide a smaller device that can deal with small spills and smaller tasks. You can pull these immediately to tackle any sudden mess. They are not the full-fledged cleaners but certainly perform well for smaller issues. It is more advisable to get two in one unit. In this way, you get a stick and a handheld option in one machine.
