Black cyclonic vacuum attachment is designed to expand the capacity to collect debris. Powerful cyclonic action captures up to 90% of dust particles before entering the main canister or dust bag, hence reduces the frequency of emptying the main canister or dust bag by up to 84%. This increases the longevity of the filter and offers the convenience of a one-touch release for easy disposal of debris. Click system securely attaches to vacuum. The cyclonic attachment is most compatible with Makita® 18V LXT® XLC03 and XLC04.
