Segway Navimow H1500E
The Tesla of Robot Mowers

Review Summary
Segway, best known for it's personal transports and scooters has brought its technical know-how to the robot mower market with the Navimow range. The H1500E or H1500N(-VF) in the US is the mid-sized garden version. But other H models are the same available for larger or smaller garden sizes.
Released in 2023 the H range is not wired, instead it uses RTK GPS, which means it's using satellites to position it. Note this is not the RTK+ system, so you will need good line of sight to the sky in your garden.
The H1500 has some nice features, rain-sensor, ability to handle 45 degree slopes, and a super-easy set-up process where you trace the edge of your lawn with your phone. The App is great too, easy adjustments to the mowing zone, and areas to avoid, removes all the faffing of resetting wires. The mower is easy clean and has a MASSIVE battery giving 4 hours solid mow time.
The VF, optional on some versions, stands for Vision Fence. This is an additional camera set-up on the front of the mower which scans for movable objects to avoid like kids toys or sports equipment.
The only minor quibbles we have with the H1500 are: firstly it's just not that visually appealing, some of the newer mowers look amazing. This is more your Ford than Ferrari. And secondly the wheels. The wheels are not great in very muddy or super-dry gardens, although you can get some aftermarket add-ons to help if they become a problem for you.
Overall this is a fantastic mower, very good tech, solid and reliable. Great app to make management easier, and Over The Air (OTA) updates to ensure it gets new features easily. We really like this mower and thoroughly recommend it.
