The improvement of S520 ,which is better than other models:

Use solid core wheel for S520, heavier rear wheel than it used for S510, it can keep from slippery when running on slopes and hills.

2.4pcs of Small blades

Please check the picture attached, increased the cutting width,also each blade with four sharp edges, every edge can used if one damaged by hard stone or other objects.

3.without ultrasonic sensors

The bumper function is good enough.

4.Improve the front wheel.

Use PPR material for the front wheel, it is softer than the original one, and against the vibration when working on the lawn.Also the front wheel with stainless steel holder, against rusting after long time using.

5.add range function:

There are four options for the ranges, user can choose thedistance when the robot hit the virtual wire according the

condition of different lawns.

 6.Different charging connection, S520 has a better connection

with the charging station, two charging heads connect the copper sheets perfectly.

7.Improve the line function:

 Change the running pattern for the line mode(Line function on):before:user has to put the robot on the back of the charging station to start, the robot will follow the wire cutting first.it is not user-friendly.

Now:The robot started on the wire or inside the virtual wire, the robot will find the virtual wire and follow it to the charging station, meet it, then back from the charging station and circle to the back of the charging station, and follow the virtual wire cutting until meet the charging station again, then back to the lawn for cutting continuously.
