I have been looking at getting one of these for months! Finally got one. Was super easy to set up. Came assembled and just had to add two brushes on the bottom. Plugged in the charger turned it on. Very simple. The hardest thing was connecting to wifi. Need to hold “dock” and “max” button on this model. The directions were wrong. But love that you can program on the app for scheduled times. Random navigation in my house but seems to get most corners. Picks up dog hair and tray is easy to empty. Would recommend this product.
