What is your Return Policy?

At OffGrid Horizon, we want every customer to shop with confidence. If something doesn’t go as planned, we’ve made returns and refunds simple and fair. Here’s how it works:

1. Return Window

You can request a return within 30 days of receiving your order. Unfortunately, we’re unable to accept returns after that time frame.

2. Who Pays for Return Shipping?

  • If your item arrives damaged, defective, or incorrect, we’ll cover the return shipping cost — and you’ll receive a full 100% refund or replacement, including any original shipping costs.
  • If you’re returning an item because you changed your mind, you’ll be responsible for return shipping, and a 25% restocking fee applies.

3. Damaged or Defective Items

Received something broken or not working properly? Contact us within 30 days. We’ll provide a prepaid return label and once the item is returned and inspected, we’ll issue either a full refund or a replacement.

4. Changed Your Mind?

If you no longer want the item, you can return it within 30 days — as long as it’s unused, unopened, in its original packaging, and in resellable condition.

5. Refund Processing

Once we receive and approve your return, we’ll send a confirmation email and issue a refund to your original payment method within 7 business days. Please allow additional time for banks or credit card companies to process and reflect the refund.

How to start a return: email sales@offgridhorizon.com or call (302) 496-3554 (Mon–Fri, 9am–4pm EST) with your order number — we’ll send return instructions and your RMA right away.

Product Description

The Sunseeker X4 is a wire-free robot lawn mower designed for yards up to 0.25 acre (about 1,000 m²). Instead of buried boundary wires, it uses 360° 3D LiDAR fused with Vision AI to map your lawn and navigate precisely — setup takes minutes, and your lawn stays neatly cut without the weekly chore.

Key features

  • Wire-free setup: 360° 3D LiDAR and Vision AI mapping, with no perimeter wire to install or repair.
  • Obstacle avoidance day and night: detects and steers around toys, pets, and garden furniture, including low-profile objects.
  • Built for complex yards: intelligent path planning, multi-zone management, no-go zones, and navigation through passages as narrow as 28 in.
  • Even cut on uneven ground: floating deck with a 7.9 in cutting width and 0.8–2.4 in adjustable cutting height.
  • Weather aware: IPX6-rated body with automatic rain detection — it docks in wet weather and resumes when conditions improve.
  • App and voice control: schedule, monitor, and update over the air from your phone; works with Alexa and Google Assistant.
  • Anti-theft lift alert for added peace of mind.

Specifications

  • Recommended lawn size: up to 0.25 acre (1,000 m²)
  • Navigation: 360° 3D LiDAR + Vision AI (L-SLAM)
  • Cutting width: 7.9 in (20 cm), 6 blades
  • Cutting height: 0.8–2.4 in (20–60 mm)
  • Slope capability: up to 45% (24°)
  • Obstacle clearance: up to 1.6 in (4 cm)
  • Water resistance: IPX6
  • Connectivity: app control, OTA updates, Alexa and Google Assistant

A practical fit for small and mid-size suburban lawns with tight passages, trampolines, toys, and pets.
