Belts are the definition of low-cost, high-payoff maintenance — you can spend ten dollars to prevent a service call, or you can save the ten dollars and pay for the service call later. Not a hard math problem.
This is the genuine Nilfisk Advance OEM BELT WESSEL POWER NOZZLE, part number L01720594, brand new in the box. Check belts at every service interval: look for glazing on the inner surface, cracks across the width, and stretched sections that don't grip anymore.
Genuine OEM belt is spec'd for the pulley diameters, the motor torque, and the load profile. Aftermarket belts of the "close enough" variety are how you end up back where you started in six months.
