I have weeds growing between my patio pavers (lots of them, as I have
been away on vacation for a while). they are a bitch to pull out,
roots are strong.

If I rent a gas powered pressure washer will that have enough cutting
power to rip them out? The patio needs cleaning anyway. Would there
be various nozzles that can rip a weed in two? I need to blow the
accumulated dirt out from between the pavers to slow them down for the
future too, pavers are butted tight making the weeds equally tight to
yank. I've used hebicides but they are still aggressive weeds.
