Main cleaning brush for TESLA RoboStar iQ400 / iQ400 Plus (replacement brush)
Main cleaning brush compatible with TESLA RoboStar iQ400 and iQ400 Plus robot vacuums. This replacement brush is designed to remove dirt, dust and hair from hard floors and carpets, restoring sweeping performance after wear or clogging. The brush fits the OEM mounting interface used in the iQ400 series and is intended for routine maintenance to maintain suction efficiency and edge-to-edge cleaning results.
The brush uses a combination of bristles and flexible fins to lift debris and guide it toward the vacuum inlet, improving debris pickup on different floor types. Replacing a worn main brush helps reduce hair tangles and maintains even brush rotation, which supports consistent cleaning paths and prevents increased motor load. The part is designed to be a direct fit for the specified TESLA RoboStar models and is made from materials that tolerate regular use and cleaning.
Turn off the robot or remove it from the docking station and access the brush compartment according to the vacuum's user manual. Remove the old brush by releasing its locking mechanism, fit the replacement brush into the same mount, and make sure it sits securely and rotates freely. Reassemble the brush guard and return the robot to service. Check the brush periodically and remove trapped hair or debris to maintain optimal performance.
For best results, inspect and clean the main brush every 1–2 weeks depending on usage and the presence of pet hair. Replace the brush when bristles are visibly worn, fins are deformed, or cleaning performance declines. Use alongside regular filter and side brush maintenance to preserve overall vacuum efficiency.
