You should be able to rake any chopped weeds off the surface now, which will enable you to see the resultant condition of the ground. After a couple of days, any substantial weeds should start to show their faces, and make it easier for you to tackle them.
In essence, don't regard rotovating as cleaning the ground, merely making it easier to clear afterwards. Hoeing the weeds off as they show should make good inroads.
Good luck!
