Review on 🧹 Enhanced Accessories Kit for iRobot Roomba 600 Series 690 680 660 651 650 (Excludes 645 655) & 500 Series 595 585 564 552, 4 Filters, 6 Side Brushes, 1 Pair Bristle Brush & Flexible Beater Brush - Ultimate Optimization by Sarah Codina

Do not buy this article! Can't even give one star. Only one brush with bristles fits from the entire package contents. The filters didn't snap to stay in place which is probably for the best as the filter material is terrible and will likely burn out the engine. Corner brushes do not match the screw holder, so the screw head may damage the floor. In general, a disgusting scam!
