I have a Hayward SharkVac XL that is almost 3 years old and this week I noticed that it is no longer running. While the red button on the electrical box turns on/off the actual robot vac doesn't make any noise or move. I have seen some people mentioned they had repaired their vacs but the main difference is a portion of their robot was operating such as a fan, suction, etc. Mine doesn't do anything. Do you think its worth taking it somewhere to repair or should I cut my losses and find a new vac?
