I purchased this vacuum to begin the process of cleaning up a very neglected home where a 103 year old lady lives. Her old vacuum leaks dirt and dust back into the air. I am very impressed with this vacuum! I love the Hepa filter and sealed, clear view canister. No dust is expelled back into the air at all!  It is very powerful and does a great job of collecting the dust and carpet debris. Each time I vacuum the carpet it pulls more and more stuff up and out of the carpet. The attachments work very well.  Because of all the dust buildup I have had to wash the canister and the filters which is a very simple process.  Everything cleans up very well. Just like brand new!  I wish Bissell made a wide, soft ceilingwall brush attachment to vacuum the walls.
