I am a real person.
Thanks for the replies.
It says on the dewalt website you can connect it to the tools with flexlock, and this is about £100 cheaper than their L class dust extractor.
Because the vacuum and the extractor are both L class I thought the vacuum would be OK on the sander.
Would I be better spending the extra money and get the L class dust extractor?
Would the extractor get rid of a lot more dust than the Vacuum?
Probably a silly question but will save me time and money, dust goes everywhere when using them sanders.
