This Dust Bin Lid Cap is a valuable spare part designed for Dyson cordless vacuum cleaners. Installed at the bottom of the vacuum's dust canister, it protects against the escape of dust or air which can lead to reduced suction. The piece is made from high-quality material which ensures a long service life. This Bin Lid Cap is an economical solution for you, allowing you to replace only the faulty part rather than the whole dust bin. It is designed for easy installation with a fitting sealing ring included. Its compatibility includes Dyson V10, V11, and V15 vacuum models, corresponding with specific dust bin part numbers for each model. This product provides a simple solution to maintain the optimal function of your vacuum cleaner.
