Welcome to the Bunnings Workshop community. It's marvellous to have you join us, and thank you for sharing your question about your Ryobi pressure washer hose.
If you have the Ryobi 1800W 2030PSI Pressure Washer, I suggest going to your nearest store and proceeding to the special orders desk. From there you can order the hose that you need. However, please make sure to double-check the model number of your pressure washer before you go to the store. Just to be sure bring the unit to the store so that the team member can thoroughly identify the model number of your pressure washer.
If you need further assistance, please let us know.
