Bissell CrossWave owners, keep your machine running like new with this replacement parts bundle! You get 3 of the 2788 Multi-Surface Pet Brush Rolls and 3 of the 1866 filters - basically everything you need for routine maintenance.

They compare to original part numbers 1618641 and 1608684. Important note though - Bissell has different types of brush rolls, so check the flange on your original roller before ordering to make sure you're getting the right style. Having fresh brush rolls makes a huge difference in cleaning performance, especially if you have pets or heavy traffic areas. The filters are crucial for maintaining proper suction and preventing odors. With 3 of each, you've got backups ready to go when your current ones wear out. It's so much more convenient than waiting until your machine stops working properly and then having to order parts. Keep your CrossWave cleaning at peak performance with these genuine-compatible replacements!
