My carppy household bagless vacuum cleaner plastic thing was next to useless, collecting more dust on it's outside than it's inside.
Got fed-up with lugging shop-vac twixt house and wshop, so I decided to do a bit of re-purposing. Mr Bagless had a short surgical meeting with Mr Screwdriver and a cunning plan was formulated.
Spent a while looking at lots of people's DIY dust separators, cyclones in the US patent office, Thien baffles, computer flow models, design specs, etc etc.
Total cost <15 + electricity.
I could have just bought another house vac, but the challenge was there. It works well, still to be refined and rendered safe.


1.140kW mono south-facing at 49*
EpEver 4210A at 24v
New (Old) 8S7P LiFe battery, 105Ah @ 26.4V
EpEver STI1000-24-230 pure sine inverter
Of course it'll work. (It hasn't caught fire yet).
