Roomba e5 junk item. I purchased it new online several years ago. It was working normally until a few days ago, but the battery may be due for replacement, as it sometimes works and sometimes doesn't. I have purchased a new one, so I am selling this one. The battery has never been replaced. The brushes have been replaced with third-party products several times, and the one currently attached is quite worn. I have not checked the operation recently, so please understand that it may stop working immediately, not work at all, or not even power on. Please purchase only if you understand this. No claims and no returns are accepted.
