Handles My Tough Yard Without Complaints, Awesome Support

I was a bit nervous about buying a robotic mower, but Sunseeker’s local support made it easy. I had a question during setup and got a fast, helpful response from a real person. We’ve got a pretty uneven lawn with a few trees and garden beds, but the X3 Plus has no problem getting around. It’s surprisingly quiet too — I can run it while my kid naps. Wish I’d bought it sooner!

Intelligent lawn mower!

So amazing! It can be used even without a cable. It's super convenient to control with a mobile phone. The lawn is mowed neatly, saving time and effort and freeing your hands!

I Wanted To Like This So Much

In Texas' 105-110°F heat, Sunseeker X7 is quiet (usable at 3am), cuts various grasses evenly, navigates slopes/obstacles well, is light and easy to clean. But it loses connection—can’t return to charger (I had to retrieve it), needs frequent remapping. App is frustrating. Returned, may try later if improved.

 Wrong robot for my terrain

Not the right to it for my yards terrain but their customer service is outstanding and I will be trying their more advanced robot in the future.

Another Sunseeker winner (Multiple updates included)

Upgraded from L22 to X3 Plus—excellent. X3 has adjustable speeds, smart patterned mowing (better than L22’s random), no wires (except antenna), and an easy app. Setup took a bit, early glitches fixed via support. Now mows 98% of lawn (vs L22’s 85%), saving time. Great upgrade!

Great customer service! I wasn't sure how to set up the robot lawn mower at first, but their support team patiently answered my questions about settings and app syncing, offering clear guidance and tips. The mower works wonderfully, and the excellent service makes it even better—you'll be well taken care of!

Another Sunseeker winner (Multiple updates included)

Upgraded from Sunseeker L22 to X3 Plus. Initial issues: setup took long, antenna fussy, stuck in holes, avoided thick grass, schedule not saving. Support fixed charging/off issue. Resolved grass patches by pre-mowing. App updated to let edge mow start/end. Now mows 98% of lawn—worth it, saving time.
