Lousy product, worse customer service.
Vacuum started just quitting in place rather than returning itself to the dock to charge after about two years. Tried to work with customer service which advised a master reset. It didn’t work so then I had a vacuum that couldn’t get through a complete remap because the battery had diminished, and it wouldn’t return to dock to charge so I couldn’t get a new map made. Roborock said the product was discontinued so they couldn’t fix it, offered me a measly $20 off a newer model. I asked for $50 and they ghosted me. Lousy product, even more lousy customer service. They don’t stand behind their stuff.
