The most important aspect of this vacuum(it’s cleaning ability) I would give 10 stars if I could. I ended up returning this for other reasons. The main reasons: the app was far behind the times. I would have loved to continue using Virtual Boundaries as opposed to tape strips. After ten cleanings it still couldn’t find its way around my house(my ecovacs has it down in 1). It is louder then most, but not to an annoying level. The quality of clean it was capable far exceeded our ecovac and even the previous shark model.
