Here are some tips for maximizing the battery lifespan of your Roomba:

  1. Fully charge the Roomba’s battery before using it. This will help extend the battery life and ensure that it runs at peak performance.
  2. Always use the original charger that came with your Roomba. Using a different charger may cause damage to the battery and shorten its lifespan.
  3. Do not overcharge the battery. Once the battery is fully charged, unplug it from the charger. Overcharging can damage the battery.
