Avoid Overcharging
Modern robot vacuums, including Narwal’s models, have built-in overcharge protection, but it’s still best not to leave them on the dock for days. While overcharging is less of an issue with advanced models, constant top-off charging can still add slight stress to the battery. If you won’t be using the vacuum for a while, consider removing it from the dock after a full charge. This small step helps maintain battery health without sacrificing convenience.
Beyond daily charging habits, some robot vacuums also benefit from a battery reset or calibration process, which can help restore lost capacity and improve runtime.
How to Reset and Calibrate a Robot Vacuum Battery
Resetting and calibrating a robot vacuum battery can help fix charging errors and improve runtime accuracy.
Some models allow a battery reset, done through a soft reset (via the app or button combination) or a hard reset (factory reset).
Calibration is also useful: run the vacuum until it fully discharges, then recharge it to 100% in one go. While calibration won’t extend the actual lifespan, it ensures more accurate runtime reporting and can sometimes recover minor efficiency loss.
For best results, only perform calibration every few months and follow your model’s instructions.
Storage Tips for Battery Longevity
Where and how you store your vacuum matters, especially if it will sit unused for extended periods.
