Review on 🔋 ANTRobut 4500mAh 14.4V NI-MH Battery Replacement for iRobot Roomba R3 500-900 Series Vacuum Cleaner with Parts by Dawn Wilson

If you want cheap but functional then you've found it. The brushes are fine and the battery works. although you MUST understand that they are simply "appropriate and functional". The brushes lie sloppy and need more thorough cleaning more often. The battery has noticeably reduced its lifespan within three months and so far (after 14 months) it has slowly degraded, it only lasts about 15 minutes and dies in the middle of the living room. To be honest, $30 a year for a decently cleaned living room every day isn't a bad deal. I will probably order again.
