SUCTION DOES NOT CLEAN!
AIR FLOW CLEANS, THEREFORE ONCE YOU LOSE THE AIRFLOW BY THE BAGS AND FILTERS BEING BLOCKED UP BY THE BIGGER PARTICLES THAT FLOW THROW THE BAG, YOU THEN LOSE YOUR AIRFLOW, AND CLEANING ABILITY.
IT IS PROVEN THAT IN THE FIRST 3-5 MINUTES 50% OF THE BAG BECOMES CLOGGED, THEN WITHIN THE NEXT 8-10 MINUTES OVER 90% ON THE BAG BECOMES CLOGGED LOSING ALMOST ALL AIRFLOW. YOU CAN LOSE ALMOST ALL OF YOUR AIRFLOW AND STILL KEEP SUCTION. BUT WITHOUT AIRFLOW YOU ARE NEVER GOING TO PICK UP ANY DIRT.
In all actuality does it really make much sense to collect all of the filth in your home in a bag full of holes.
