Review on 🧹 YOKYON Replacement Parts Kit for iRobot Roomba 600 Series Vacuum - Bristle & Flexible Beater Brush, Armed-3 Side Brush, Filters - compatible with 614, 618, 620, 630, 650, 651, 660, 665, 680, 690, 692, 694 by Yvonne Gallegos

Works just like the originals. The bristle brush is less coarse than the original, but that doesn't bother me. Also, the brush arm was too long and interfering with the touchpads, so I shortened them a bit. I'm glad I have all these spares instead of meticulously cleaning each part because originals are expensive.
