If you have a Ryobi circular saw and want to hook up to a Dyson vacuum, this is the solution.

This adapter clicks on the Ryobi saw's vacuum receiver. The adapter's other end can be inserted into a Dyson hose connector.

Note that your saw and vacuum's connectors may vary. I use a Ryobi ONE+ HP cordless saw (PSBCS01) and a Dyson V8 cordless vacuum.

Tip: the adapter should push fit (snug fit) into the Dyson connector. If it's too loose or too tight, slightly adjust the model size in your slicing software.
