• Condition: 100% brand . All parts are tested and quality controlled prior to shipment for reliable performance. • Function and benefit: These elastic rubber drive belts restore brush roll rotation and cleaning performance when a worn or broken belt stops the brush from spinning. Durable and flexible construction resists stretching and cracking for longer service life, so your vacuum maintains effective agitation and hair/debris pickup between replacements. Easy to install — simply remove the damaged belt and fit the belt into the original position. • Material and performance: Made of quality elastic rubber for flexibility and longlasting reliability. Designed to maintain consistent tension and smooth transfer of motor power to the brush roll under normal household use. • Compatibility (replacement part numbers): for 1LU0310X00 / 3720310001 / 1540310001. • Compatibility (models): Compatible with Dirt Devil (Royal) Featherlite / Powerlite / Swivel Glide / Power Max Pet upright vacuums and these model numbers: UD70100, UD70100CDI, UD70105, UD70110CDI, UD70115, UD70125, UD70125CDI, UD70161, UD70163, UD70165, UD70165CDI, UD70167, UD70167P, UD70168, UD70169, UD70169CDI, UD70172, UD70172FDI, UD70180, UD70181, UD70183, UD70185, UD70187, UD70188, UD30010RM, UD30005B, M110009, M085335, M085440, M088160 and other compatible vacuum series. • Package contents: 2 x replacement belts (as pictured).
