I have had this vacuum for about a month.
It's perfect for this older person, so lightweight .and it goes around furniture so easily. 
This is my first Shark and I am a already completely in love with it. I am already telling all my older friends how wonderful it is and how it makes it so much easier for me to keep up with the dust, dirt, and sand from my poodle!
It is easy to empty the dust cup!
The accessories that I think would be most useful for me would be:
B. The 12" Crevice Tool
C. The Dusting Brush
F.  The Duster Crevice Tool
H. The Under-Appliance Wand
I really like that the Premotor Filter is washable, and the recommendation for replacing it is every 2 and a half years.
The Post Motor Filter is also washable and the recommendation for it's replacement is 3 years!
I think this is your newest lightweight stick style vacuum, and Thank You Shark Engineers!!!
