Vacuum without a bag SHARK HZ700

I used to have the Shark Bagless vacuum cleaner Hz602 Ultralight Pet Pro that I ordered from RefurbLane and LOVED it! I moved so I sold it at a yard sale. I purchased this one and so far, I like it. The carpet function is intense and it has a hard time rolling smoothly over throw rugs. The attachments are great for getting hard to reach places. I'm curious to see if all the extra bells and whistles last over time and if they have any effects on the durability of the vacuum. Time will tell!
