Whether you have the Ryobi leaf blower or another kind of blower, if you want to clean the dryer vent using a leaf blower, follow the next steps: 1. Take off the hose so you get access to the dryer vent. To do this, drag the dryer from the wall and take off the hose with your hands or use some tool to unscrew it if necessary. 2. Take off the cover from the external ventilation hole to not to break the tubing or leaf blower under the pressure. You will also need some tool for unscrewing to do this. 3. Remove the dirt from the outside part of the vent using a brush or a vacuum cleaner. 4. Insert the blower into the dryer vent. 5. Don’t let the air pass back past the nozzle. For this, it’s necessary to seal the vent. The most common way to do it is to use weather a duct tape or a towel. 6. Now you can finally turn the leaf blower on. Give the leaf blower a few short blasts to check if everything is okay. Then, leave it blowing for at least 30 seconds. 7. Check if the leaf blower has done its job well and left no lint inside the pipe. 8. Clean the external part of the vent as the work is completed successfully. 9. Remove the leaf blower and assemble the dryer vent back: reattach the dryer to the vent and screw the external cover back.
