Thank you for allowing me to test this awesome product! The process of putting the Shark cordless vac together was simple. I thought I might have to charge it,but it worked right out of the box. The suction is strong,and it won't miss a crumb,cobweb,or pet hair. Its light weight,and i noticed the sound didn't make my cats run for their lives which was a plus,but the most amazing part is when you dock it and it cleans itself!! Wow!! I love it!!
