This.
We used to have fake grass in my work and it was a huge pain because you couldn't really pressure was it without causing damage, you could use a really low setting and a broad spray but it wasn't ideal. And then you'd just vacuum.
There's no reason you can't vacuum an outdoor space, it's all dirt. I use fly spray outdoors. It's all flies. This indoor/outdoor thing lives in your head rent free
