your vacuum passes slightly.
• empty the dirt collection unit or bag regularly. clean or replace the machine’s filters regularly as well.
• if odor in the carpet or vacuum cleaner appear then that can be a problem. put 1/2 cup of baking soda or lavender flowers in the dirt collection unit or bag. you could also sprinkle the baking soda or lavender flowers all over the carpet, then vacuum up. this will leave your room smelling much nicer.
