I tried the Shark Navigator Speed Upright Vacuum with Lift-Away and Self- Cleaning Brushroll. This is a great vacuum with powerful suction. The Lift-Away feature allows you to separate the vacuum from the wand and Brushroll to easily clean stairs and vehicles. The unit was very easy to assemble. The Self-Cleaning Brushroll is newer technology that cleans hair from the Brushroll so you do not have to get out the scissors and cut hair from the roller. The power cord is ample length for most rooms. I am surprised the accessory holder only holds one of the three accessories. This is a great vacuum and I can assure you that you will be satisfied with this purchase.
