MA MowAutonomous Editorial Team · Updated 2026-09-05 · 10 min read

Robot mowers are $1,300-$3,900 investments. Understanding the warranty before you buy can save you hundreds of dollars if something goes wrong. This guide covers warranty terms for every major brand.

Standard Warranty Terms by Brand

Most robot mowers come with a 2-year limited warranty: (1) Segway Navimow: 2-year limited warranty (covers manufacturing defects, not normal wear). (2) Mammotion: 2-year limited warranty (covers manufacturing defects). (3) Worx: 3-year limited warranty (longest standard warranty). (4) Dreame: 2-year limited warranty. (5) ECOVACS: 2-year limited warranty.

What's Typically Covered

Standard warranties cover: (1) Manufacturing defects in materials and workmanship. (2) Motor failure. (3) Electronics failure (motherboard, sensors). (4) Charging station defects. (5) Battery failure (within the first 2 years only — battery degradation after 2 years is not covered).

What's NOT Covered

Standard warranties do NOT cover: (1) Normal wear and tear (blades, wheels). (2) Damage from misuse (dropping, hitting objects). (3) Water damage from submersion (IPX5/IPX6 covers rain, not submersion). (4) Damage from pests (rodents chewing wires). (5) Cosmetic damage (scratches, dents). (6) Battery degradation after 2 years. (7) Theft or loss. (8) Damage from unauthorized repairs.

Extended Warranties — Worth It?

Most manufacturers offer extended warranties (3-5 years) for $100-$300. Worth it for: (1) Premium mowers ($2,500+) where repairs are expensive. (2) Properties with harsh conditions (extreme heat, cold, or humidity). (3) Buyers who want peace of mind. Not worth it for: (1) Budget mowers ($1,500 or less) — the warranty cost is a high percentage of the mower cost. (2) Properties with mild conditions and careful use.

How to File a Warranty Claim

To file a warranty claim: (1) Contact manufacturer support via email or phone. (2) Provide proof of purchase (Amazon order number, receipt). (3) Provide the mower's serial number (found on the mower or in the app). (4) Describe the issue and provide photos/videos. (5) Manufacturer will send a shipping label for repair. (6) Repair typically takes 2-4 weeks. (7) If the mower can't be repaired, manufacturer may replace it.

Third-Party Protection Plans

Retailers like Amazon offer third-party protection plans (e.g., Asurion) for $100-$300. These plans: (1) Cover accidental damage (drops, crashes). (2) Cover theft (with police report). (3) Cover battery degradation. (4) May have deductibles ($50-$100). (5) May be easier to claim than manufacturer warranties. Worth considering for expensive mowers in theft-prone areas.

Frequently Asked Questions

How long is a robot mower warranty?

Most robot mowers come with a 2-year limited warranty. Worx offers 3 years (longest standard). Extended warranties (3-5 years) are available for $100-$300. The warranty covers manufacturing defects but not normal wear, misuse, or battery degradation after 2 years.

Does a robot mower warranty cover theft?

No — standard manufacturer warranties do not cover theft or loss. For theft coverage, you need either: (1) A third-party protection plan (e.g., Asurion via Amazon, $100-$300). (2) Homeowners insurance (check your policy — most cover personal property including robot mowers). (3) A dedicated GPS tracker for recovery.

Is an extended warranty worth it for a robot mower?

For premium mowers ($2,500+), yes — repairs can be expensive and the $100-$300 extended warranty is cheap insurance. For budget mowers ($1,500 or less), probably not — the warranty cost is a high percentage of the mower cost, and most issues occur in the first 2 years (covered by standard warranty).
