Left drive wheel assembly designed as a compatible replacement for iRobot Roomba robot vacuum cleaners. This powered wheel module controls movement, traction, and steering, helping the vacuum maintain stable navigation and smooth operation across different floor surfaces. Compatible with iRobot Roomba MAX 705 Vac Series robot vacuum cleaners, including RVH-Y1, W155020, W155040, and W155060 models. Not compatible with Combo series models. This is the LEFT wheel when viewing the robot from the top. When the vacuum is flipped upside down, the same wheel appears on the right side. Please verify the side marking on your original wheel before purchase, since left and right assemblies are different and cannot be interchanged. A damaged or worn wheel assembly may cause slipping, reduced traction, uneven movement, navigation issues, or abnormal wheel noise. Replacing the drive wheel helps restore smooth mobility and reliable cleaning performance. Designed to match original specifications, this assembly includes the integrated wheel motor and housing for direct installation using original connectors and mounting points.
