I really love this Shark Al Ultra 2-in-1 robot.  It has so many awesome features.  I was happy there was no assembly, it came ready to go. You just have to set it up, charge it, and download the app. set up an account,  Or you can use a voice feature.  It is much better to use the app.   It vacuums, does moping and cleans hard floors.  It works great going in rows and missing anything in its way. It is very systematic and your floors look amazing.  I love having the ability to schedule runs when I am not at home.
I am older and disabled and this is a lifesaver for me because I have trouble vacuuming and mopping. This is a durable well-made product and a good value.
