Buy a shark. Show up with the same vacuum as your customer and charge 100 bucks an hour. Good plan.
meh..
no knock on dog 'n pony shows, glitz 'n pretty lights...
but it's all fluff
bring in any decent vac and use it and you've done more than 92.8777% of CC'ers
It's also an opportunity to educate them that it's not so much the vac, but most about keeping it maintained (like empty the dawgone bag or cup and clean filters more than once a millennium) and how to use it right (like stop "sawing" back n forth at warp speed) and let the vac do the work
they'll appreciate and get more value out of that than a vac they've never seen before
having said that.....if I was jan/san, a bitty head Shark would be my last choice
