Right and left drive wheel modules compatible with i7, i7+, i8, i3, i6+, J7, E5, E6, and E7 robotic vacuum models. Designed for a reliable fit and smooth, repeatable motion. Key benefits Restores mobility: worn or damaged drive wheels to bring back smooth navigation and consistent cleaning performance. Better traction and stability: traction wheels improve movement across carpets, hardwood, tile, and thresholds so the robot crosses transitions and stays on course. Durable construction: Built from robust materials to withstand daily use and resist wear, extending the working life of your vacuum's drive system. Easy, fast replacement: Userfriendly design lets you install the right and left modules quickly with minimal tools or effort, reducing downtime. Improved navigation accuracy: Precise wheel movement helps the robot handle obstacles, corners and tight spaces more effectively for a more thorough clean. What these modules do Provide drive power and traction for forward, reverse and turning motions. Maintain consistent wheel rotation signals for accurate mapping and obstacle avoidance. Reduce slippage and misalignment that can cause missed areas or navigation errors. Compatibility Specifically designed for: i7, i7+, i8, i3, i6+, J7, E5, E6, and E7 models. Includes both right and left drive wheel modules for complete replacement. Practical use scenarios Maintenance replacement: Swap in wheel modules after months of use to restore original handling and reduce navigation faults. Multisurface homes: Improve performance in houses with mixed flooring (hardwood, tile, low to mediumpile carpet) so the robot traverses transitions and rugs more reliably. Cluttered or narrow rooms: worn wheels to help the vacuum maneuver around furniture legs, doorframes and tight spaces without getting stuck. What to expect Noticeable improvement in traction, predictable movement, and fewer navigation interruptions after installation. Longlasting operation thanks to robust component construction. Quick installation so you can the vacuum to service immediately. Includes One right drive wheel module and one left drive wheel module compatible with listed models. If your i7, i7+, i8, i3, i6+, J7, E5, E6, or E7 robotic vacuum is showing reduced mobility, slipping, or navigation errors, these replacement drive wheel modules restore reliable movement and improve overall cleaning results.
