I'm selling our Roomba model J7. It's 2 years old now, but was only used for about a year. It worked really well, but having the house divided up with baby gates made it difficult to use effectively so we bought a new vacuum on Black Friday last year. The Roomba has just been sitting unused ever since.
You can set up a schedule for it to run on, use the app to designate which rooms, and how, you want it to clean. It has the self emptying feature where it returns to the dock and dumps the bin when full, then resumes cleaning wherever it left off. You can also just send it out off schedule to run whenever, even to just a specific room if needed.
Best way to contact is through Classifieds. Thank you!
