Redecker make a leaf cleaning brush. Of course it’s for indoor house plants, but I had few moments of laughter thinking of carefully cleaning random garden leaves before vacuuming the lawn…
Back into serious mode. DON’T USE CHINESE UNBRANDED ELECTRICAL ITEMS. Your item is highly unlikely to meet Australian electrical safety standards. I will never understand the penchant to save a few dollars while putting one’s life at risk.
If your item isn’t as described, open a return request for a refund.
If it IS as described, and you simply didn’t read the full description or realise that your leaf thingy does dual duty, that’s another thing altogether.
