The Eufy Robot Vacuum 11S Max has a battery life that can last up to 100 minutes on a single charge, according to the manufacturer. This should be plenty for most medium-sized homes. When the battery gets low, it’s supposed to head back to its charging base on its own to recharge and then pick up where it left off.
But, according to our research, the vacuum can sometimes have trouble finding its way back to the base, especially if it’s far away or there’s furniture in the way. This happens because the 11S Max uses bounce navigation, which isn’t as precise as some models with advanced mapping technology.
To help it out, many folks have found it useful to put the charging dock against a wall with no obstacles around it. Keeping a clear path and cleaning the infrared sensors on the vacuum can also help it find its way back better.
Also, if the battery is really low, the vacuum might struggle more to get back to the base and sometimes might need a little help getting there. This is more common in cluttered spaces or homes with more complex layouts.
In short, the Eufy 11S Max has good battery life for most cleaning jobs, but how well it finds its way back to the charger can depend on your home’s setup and how clear the path is.
