The Katerelis 26 Pack Replacement Parts is designed for compatibility with a wide range of robot vacuum models, including E, i, and j series devices such as i2, i3, i3+, i4, i4+, i6, i6+, i7, i7+, i8, i8+/Plus, e5, and e6. This comprehensive kit contains two sets of multi-surface rubber roller brushes, eight filters, eight side brushes, and eight dust bags, offering a complete maintenance solution for extending the lifespan and performance of the vacuum unit. The multi-surface rubber roller brushes are constructed from durable materials that effectively agitate dirt and debris from hardwood floors, tile, carpet, and other surfaces without causing damage. The combination of rubber and bristle design allows for efficient pickup of fine dust, pet hair, and larger particles, ensuring thorough cleaning across various floor types.

The filters in this pack are made from high-quality synthetic fibers that capture microscopic particles, including allergens and dust mites, helping maintain indoor air quality. Their layered structure balances airflow with filtration efficiency, preventing clogging and reducing the strain on the vacuum motor. The side brushes are crafted from stiff yet flexible nylon filaments that sweep debris away from edges and corners, directing them toward the main brush. Each side brush is precisely molded to fit the original mounting points, ensuring stable rotation and consistent cleaning performance.

The dust bags feature a multi-layer construction with a leak-proof seal, trapping fine dust and odors while providing easy disposal. From a manufacturing standpoint, each component undergoes quality control checks to meet dimensional tolerances, ensuring a snug fit and reliable operation. The rubber roller brush uses a soft, anti-static rubber compound that reduces hair wrap and minimizes noise during use. The overall build of the replacement parts is intended to match or exceed the original equipment specifications, offering a cost-effective alternative to brand-name replacements.

The kit is packaged in a compact box, and installation is straightforward—users can swap out worn parts without special tools, following standard maintenance procedures for compatible robot vacuum models. In terms of value, the Katerelis 26 Pack provides a generous quantity of replacements at a very affordable price point. Given the price, this kit delivers significant savings compared to purchasing individual replacement parts from the original manufacturer.

It is suitable for households with multiple pets or high-traffic areas that require frequent maintenance. The components are designed for long-term durability under regular use, and the materials used are chosen to resist wear and maintain performance over repeated cleaning cycles. This set is an economical choice for users who want to keep their robot vacuum operating efficiently without frequent reordering.
