there are folks who make their own version of 'diy flowbee' using regular electric hair clippers & makeshift nozzle/hose connector
so i saw a Y. T. vid about someone converting their ordinary clippers into vacuum clippers & decided to do the same
i own a wahl corded color pro clippers & cut off the top of a gallon plastic milk jug
then i tape the top of milk jug onto clippers near the blades (be sure to throw out the jug cap)
i then connect the clippers into shop vac hose (ridgid 6000rv 6 gal vac)
