I have a Yorkleen WV1 which I bought second ( or more ) hand. I replaced all the filters at a cost of about £50. The WV1 is still available new at £425 + VAT so at that price I was expecting pretty good performance, but I have to say I am not so impressed. I have a short ( say 4ft) length of 100mm flex hose and tried vacuuming the workshop floor and whilst it does suck up turning chips etc I have to hold it really close to the waste for it to be effective. Any chips more than about 4" away don't move. I wanted it for collecting dust from the lathe when sanding and it does seem to work then, and I can see the dust being drawn away. I also use it for bottom dust extraction from my table saw.
I was thinking to use the Yorkleen through a separator, but with the extra flexible hose that would reduce the suction even more. Plus the separator (Laguna) uses 63mm connections so it would be 100mm hose, 63mm reducer into separator drum, 63mm outlet and back into 100mm flex hose to the saw / lathe.
So I was wondering how this compares with say, the SIP at under £100. What do people think about the SIP in terms of chip clearing?
