After several attempts, and customer support calls, from different family members, we have NOT been able to get this device to connect to the phone or home wifi. The customer support was NOT helpful and seemed to be reading off a card. They became very ill mannered, raising voices and being down right rude, while trying to help us with their product. We have tried several different things but can not gain the full benefit of this device. When it free roams it does clean well. Hopefully no one else has to deal with the rude, ill mannered, customer support of Deebot. I wish you the best if you choose to purchase this product.
