Waste of money App is impossible to use unless you have an ipad or a smart phone,,,I only have a desk top computer and land line phonebecause cell phones have no reception where we live in the woods,,,,had to borrow this pad from my Daughter in the city in order to get the app. There must be another way to program and interact with i robot! Frustrating! Nothing in the ads or on the box even said you have to have wi fi. WHY no instructions IN the box ? need a printed booklet or cant use irobot.
