The best thing about Segway Navimow is how it just keeps getting better.

The latest mower firmware and Navimow App updates released a few days ago have added great new features and even more improvements to the world's most advanced robotic lawnmower.

First, the fun stuff: you can now 'doodle' on your lawn. Pick a shape - a heart, a star, a cat face and more - and Navimow will "draw" it on the lawn by leaving the shape un-mown for up to 6 days. The grass inside the shape grows taller than the surrounding lawn, marking out your design for all to see. You can scale, rotate and position the shape however you want.

Next up are Mowing Reports. This feature tracks and displays all activities, and can be used as a reference to adjust mowing schedules. Sort by day, week or month the number of mows, mown area and mown hours, all at a per-zone level of detail.

Meanwhile, on the inside Navimow received improved Blade Motor firmware, Telematics BOX firmware, and EUC firmware.

Finally, Navimow now works 5% longer per recharge cycle.

On your phone the Navimow App has an improved layout, placing the most commonly used features within easier reach, and less commonly accessed features into menus.

And the best thing of all? This and every upgrade is free. Upgrades are automatically installed 'over-the-air' into your Navimow and phone (of course, you're asked to confirm first if you'd like to go ahead with each update with a tap of a button).
