I designed a customized main brush for Xiaomi / Roborock using car window wiper blades. To create this modification, you'll need to obtain the rotating part and pin from the original main brush. Simply press the pin into place in the new model and attach the rotating part. The necessary components can be found in the accompanying images. I used the following Wiper Blade for this project: https://www.banggood.com/custlink/KvvGmu1ZG7 As an update, I've made several improvements to the design since its initial posting. On October 23rd, I added a revised mid-section design along with a spacer between the wiper blades. Additionally, I included a cutting guide for the wiper blades, which are 53mm in length. The modifications were accompanied by photos. On October 24th, I posted an updated version of the mid-section design, labeled MidV9. This revised model incorporates center cut holes to address some dimensional discrepancies in the cuts. Overall, this customized brush has proven to be a significant improvement over the original. It collects less hair and cleans more efficiently, making it a worthwhile upgrade for anyone looking to enhance their Xiaomi / Roborock's cleaning capabilities.
