Review on 🧹 Enhance Cleaning Performance with YOKYON Replacement Parts Kit for iRobot Roomba i7 i7+ i3 i3+ i4 i4+ i6+ i8 i8+ J7 J7+ Plus E5 E6 Vacuum - Multi-Surface Rubber Brushes, HEPA Filters & Side Brushes by Samantha Cameron

Worthy. Spare parts are clearly of low quality. There is a small gap between the rollers that the OEM doesn't have and they seem/pretty cheap and not that strong EVERYWHERE. The side brushes and filters seem to be good. I have no way of measuring if they stop as many particles as the OEM, but they fit great and capture dust/dirt. final quality.
