How Much Does a Robot Mower Cost in Minnesota? Full Breakdown (2026)

People tend to find one price online and assume that's what they're actually going to spend. The reality is a little more nuanced. Here's the full cost picture for a Minnesota homeowner in 2026 — mower, installation, ongoing costs, and total ownership over five years.

The Mower Itself

Robot mowers generally fall into three price tiers based on capability:

Entry-level ($1,200–$1,800): These handle small, flat lawns up to about a quarter acre. Basic GPS or boundary-wire navigation. Fine for simple properties but not well-suited to Minnesota's typical sloped lots, multiple zones, or larger acreage. Wire-based models in this range have the additional issue of freeze-thaw damage to buried boundary wire over a Minnesota winter.

Mid-range ($1,800–$2,500): This is the sweet spot for most Twin Cities homeowners. Wire-free GPS systems like the Segway Navimow H series fall here. These handle lots up to 2.5 acres, slopes up to 84%, multi-zone properties, and full app control. This is the range Romow installs most frequently.

Premium ($2,500–$4,000+): Larger lot capacity, more sophisticated vision systems, AWD capability for extreme terrain, and commercial-grade durability. Relevant for very large properties or highly complex layouts.

Installation Cost

This varies significantly depending on whether you choose a wire-free or boundary-wire system.

Wire-free systems like Segway Navimow require the technician to walk the property boundaries with the mower and map them digitally. Romow charges $150 for this. It takes 1–2 hours. Nothing is buried. Nothing is disturbed.

Wire-based systems require physical installation of a perimeter wire around your entire mowing area. This is labor-intensive, disruptive to the lawn, and typically costs $200–$800 professionally depending on lot size and complexity. In Minnesota, this wire is also vulnerable to freeze-thaw damage and may need partial re-installation each spring.

Ongoing Annual Costs

This is where many buyers get surprised. Robot mowers are not zero-cost after purchase.

Replacement blades: $25–$40 per season. Robot mowers use small razor-style blades that need to be swapped 2-3 times per mowing season. A set of 9 blades typically costs around $30.

Battery replacement: $150–$300 every 3–5 years. Lithium-ion batteries degrade over time. Budget for eventual replacement after year three or four.

Cleaning and maintenance: If you handle it yourself, this costs nothing but time — maybe two hours across the whole season. If you use Romow's monthly maintenance plan ($50/month, seasonal), everything is handled for you including blade changes, cleaning, and performance checks.

Winterization: In Minnesota, you cannot simply leave the mower outside. The battery needs to be stored properly and the unit needs to be brought indoors. Romow offers winterization service. If you do it yourself, it costs nothing but 30 minutes of your time.

Electricity: Negligible. Running a robot mower charger all season costs approximately $15–$20 in electricity.

5-Year Total Cost of Ownership

For a mid-range Segway Navimow installation with Romow:

• Mower: ~$2,200

• Installation: $150

• 5 years of blades: ~$150

• Potential battery replacement (year 4): ~$200

• Winterization (DIY): $0

Total 5-year cost: approximately $2,700–$3,100

For comparison, a weekly lawn service at $65/visit over 23 weeks runs $1,495 per season, or $8,000+ over five years with typical price increases.

What About Financing?

At this time, Romow does not offer in-house financing. The mowers are available for direct purchase through Romow or directly from Segway Navimow. Some homeowners use home improvement credit lines or 0% intro APR credit cards to spread the upfront cost.

If you're looking at the purchase as an investment — which financially it is — the break-even against lawn service is typically 18–20 months.

The Bottom Line on Cost

The upfront cost is real and it's not nothing. But the five-year economics strongly favor the robot mower for most homeowners currently paying a lawn service. For DIY mowers, the break-even is slightly longer but the time savings argument remains compelling.
