Makita has come out with a new cyclone vacuum attachment (199491-1) that works with their cordless hand vacs, but it could also potentially be used with other vacuums

They say that it captures up to 90% of dust particles, which helps to “reduce the need to empty vacuum main canister/filter by up to 84%.”

It can be rotated or repositioned, in case you need to use the vacuum in tight spaces

• Separates 90% of dust to maintain suction power
• Dust collection capacity: 400 ml
• One-piece mounting and removal of the dust cover
• Ideal for Makita cordless vacuum’s DVC261, DVC260, DCL180, DCL181, DCL182, CL106FD, CL108F
