Light weight lithium ion batteries allow mowers to cut longer and recharge much faster. In fact some can recharge in as little as 4 hours allowing the mower to go out twice a day if needed.

In addition to faster recharge times, lithium ion batteries do not have the ‘memory’ problems associated with lead acid batteries. Basically the memory effect is caused when a battery is not fully discharged on a consistent basis, they remember the shortened life cycle, reducing the useful length of time until the need to recharge.

Robotic lawn mowers have become more reliable too. The addition of thermistors that detect when motors are overheating and less heat sensitive circuit boards and higher quality components extend the life expectancy past 10 years, about the same as a new quality riding lawn mower.

Robotic lawn mowers are now pretty much maintenance free. Changing the blade once a year and winter storage is about all the attention needed on a routine basis.

Robotic lawnmowers are now able to handle yards as small as 1/8 acre up to 5 acres. Depending on the model, they can handle slopes of up to 30 degrees. All major brands of robotic lawn mowers are waterproof and can remain outdoors all mowing season long.

Residential robotic lawn mowers require a perimeter wire similar to an electric dog fence to be laid prior to operating. Laying the wire is a one-time event that will last the life of the mower.
