So happy with this product! The Shark Robot amazes me again! It can be controlled from my phone if I am out also through Alexa or Google Assistant. Completes a thorough clean on carpets and floors with a deeper clean. Three brushes help it get in corners and along your walls. Pet hair.   no problem! The Robot has a two hour run time and because it has the three brushes, it collects more at one time. Love it!
