I love the convenience. I use it 2 to 3 times a day in a small area for 15 minutes each time to clean up the mess my 3 pets make.
Every week, I clean the brushes and that is quite a task. But, I found this pet brush that they now make which comes with a cleaning ring. It is a whole lot easier to clean.
For the 7 hours a week that I use this sweet machine I spend 20 minutes cleaning it. It is worth it as it cleans hair off carpets better than any other vacuum can.
