Eureka Excessive Power Draw

Vacuum’s runtime is significantly shorter than specified even with a new battery.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Clogged filters causing high load, Worn motor drawing extra current, Constant use in MAX mode, Faulty control PCB not regulating power

Safety first: Remove the battery before cleaning or opening the unit.

Steps to try:

Clean filters and airflow: Ensure all filters and air passages are clean to reduce motor load.
Use appropriate mode: Compare runtime in standard vs. MAX mode. MAX mode will always reduce runtime significantly.
Check for overheating: If the unit gets very hot quickly, the motor may be failing and drawing more current than normal.
Replace motor or PCB: If cleaning and mode changes do not improve runtime, replace the motor assembly or main control PCB.
