App stopped working as of today. Just used vacumm yesterday. Today states vacumm not connected. Tried on both my galaxy 20 and wife iPhone 12. Did a factory reset now just gets stuck on connecting to wifi. It shows the Irobot 3 but then just sits on verifying password and cant proceed. Brought it over to my friends house to try on their wifi, same issue. I would never recommend this vacuum we had it for 6 months and it's always issues, loud and constantly gets stuck or lost. overprice junk
