Quick Answer: A manufacturer-certified refurbished robot mower costs more than a random used listing but comes with a real warranty — Segway’s Navimow Certified Refurbished program discounts units roughly 32% off retail with a 2-year limited warranty, and Walmart’s Restored Worx Landroid listings carry at least a 1-year warranty with battery and charger included. That’s a smaller discount than the 40-55%-of-MSRP typical of private used listings, but it removes the biggest risk of buying secondhand: a dead battery or missing dock with no recourse.
Most robot mower shoppers only think about two options — buy new, or take a chance on a stranger’s Facebook Marketplace listing. A manufacturer-backed refurbished program is the middle path, and in 2026 it’s a real option for at least two major brands.
What “refurbished” actually means here
A refurbished robot mower has been returned (often for a minor cosmetic issue, a customer return, or a reseller overstock unit), then inspected, repaired if needed, cleaned, and functionally tested before resale — with the manufacturer or an authorized retailer standing behind it. That’s the key distinction from a used listing: someone with access to genuine parts and diagnostic tools verified it works before you paid, and you get a warranty if it doesn’t hold up.
Refurbished programs by brand (2026)
Segway Navimow — Certified Refurbished
- Sold directly through Segway's own Navimow refurbished storefront, not a third-party reseller.
- Segway advertises units as refurbished to "almost mint condition" with official Navimow service backing them.
- The 2-year limited warranty is the longest of any refurbished robot mower program we found — close to what you'd get buying new.
Worx Landroid — Restored (via Walmart)
- Listed as "Restored" rather than "refurbished," sold through Walmart's Resold program covering models like the Landroid S, M, L, and the boundary-free Landroid Vision AI.
- Restored Premium units are tested to like-new performance and come from the manufacturer, a manufacturer-authorized seller, or a Walmart-trusted seller.
- Battery and charger are included in the listings we checked — unlike many private used sales, where the dock is the first thing to go missing.
Amazon Renewed
- Robot mowers appear far less often in Amazon Renewed than smaller electronics — don't count on stock being available for the specific model you want.
- When a listing does exist, Amazon backs it with a 30-day return window plus a free 11-month limited warranty serviced by Asurion, per Amazon's Renewed Guarantee terms.
- Worth a quick search before assuming your only secondhand option is a private listing.

Refurbished vs. used: the real tradeoff
| Manufacturer refurbished | Private used listing | |
|---|---|---|
| Typical discount off MSRP | ~32% (Navimow) | 40-55% |
| Warranty | 1-2 years | None (most manufacturer warranties don't transfer) |
| Battery health verified | Yes, by the seller | No — you inspect it yourself |
| Dock/charger included | Yes, listed units we checked | Not guaranteed |
| Brand availability | Segway Navimow, Worx Landroid, occasional Amazon Renewed | Any brand |
Which one should you buy?
If you want a Segway Navimow or Worx Landroid and the refurbished discount is available, it’s the lower-risk choice — you’re trading roughly 10-20 percentage points of discount for a real warranty and a pre-verified battery. That math favors refurbished most clearly on higher-end units, where a warranty claim or dead battery would otherwise cost hundreds to fix. If you’re set on a brand without a refurbished program — Husqvarna or Mammotion, as of 2026 — or you want the absolute lowest price and are comfortable inspecting a listing yourself, our used robot lawn mower guide covers what to check before buying private.
The bottom line
A certified refurbished robot mower is worth the smaller discount when the brand offers one: Segway’s Navimow program cuts roughly 32% off retail with a 2-year warranty, and Walmart’s Restored Worx Landroid listings carry at least a 1-year warranty with the dock included — both meaningfully lower-risk than a private used listing with no warranty at all. If your target brand doesn’t run a refurbished program, or you want the deepest possible discount and don’t mind doing your own inspection, a used marketplace listing (see our used robot lawn mower guide) still saves more money up front.
