I previously had the shark AV752 ION Robot Vacuum, its a HUGE upgrade compared to this one! Before the vacuum wouldn’t have a designated direction it would pretty much bump into everything and be all over the place, compared to this one it pretty much goes row by row and the app features are way better! And also self cleaning! After each run it does back to its dock and cleans it self out. I would definitely recommend this is a life saver! Especially with kids there’s so much that needs to be done so I like how sweeping the floor isn’t a task for me anymore lol.
