# Is a robot lawn mower worth it? The 3 year cost math

Is a robot lawn mower worth it? For a quarter acre lawn you now pay a mowing service for, usually yes: a $1,049 wire free robot costs about $1,235 over 3 years, against $2,700 to $6,000 for 3 years of weekly service.

## Short answer

Yes, if you pay someone to mow a lawn under about an acre that is not steeper than the robot is rated for. Over 3 years the cheapest robots cost $1,035 to $1,235 all in, while HomeGuide puts weekly service on a quarter acre at $900 to $2,000 a year. No, if you mow yourself with a push mower and do not value the time: a gas push mower plus yearly tune ups runs about $310 to $525 over 3 years, so a robot never pays for itself in cash.

| Option | Upfront | 3 year running cost | 3 year total |
|---|---|---|---|
| Gas push mower | $175 to $300 (HomeGuide average) | $135 to $225 in tune ups ($45 to $75 a year), plus fuel | About $310 to $525 plus fuel and your time |
| Battery push mower | $200 to $500 (HomeGuide average) | Blade sharpening, $5 to $15 per blade | About $215 to $545 plus your time |
| Weekly lawn service, 1/4 acre | $0 | $900 to $2,000 a year (HomeGuide annual contract) | $2,700 to $6,000 |
| Segway Navimow i206 AWD (0.15 acre) | $849 | About $186 (blades, 4G data years 2 and 3) | About $1,035 |
| Segway Navimow i210 AWD (0.25 acre) | $1,049 | About $186 (blades, 4G data years 2 and 3) | About $1,235 |
| Mammotion LUBA mini 2 AWD (0.37 acre) | $1,799 | $245 (blades) | $2,044 |
| Mammotion LUBA 3 AWD 1500 (0.37 acre) | $2,399 | $294 (blades) | $2,693 |
| Husqvarna Automower 410 iQ (0.5 acre) | $2,599.99 | About $130 (blades) | About $2,730 |
| Segway Navimow X430 (1 acre) | $2,499 | About $354 (blades, cellular service) | About $2,853 |
| Ecovacs GOAT A3000 LiDAR PRO (0.75 acre) | $2,499.99 | About $390 (blades) | About $2,890 |

## How we did the 3 year math

For each robot we added the price on the maker's store, as of October 15, 2026, to the parts and service it needs over 3 years. Those running costs come from our ownership data for each model: blade packs at the maker's replacement interval, plus any data plan once the free period ends. Navimow, for example, charges $32.90 a year for 4G data after year one. Mammotion includes 3 years of 4G data, and Husqvarna lists no fee for Automower Connect or EPOS and includes a year of blades.

Electricity is small. LawnStarter says recharging a robot mower costs only a few cents a session. We left it out of the totals for every option, the same way we left out gas for the push mower, because neither changes the result.

For lawn service we used HomeGuide's figures: $30 to $85 per visit for a recurring 1/8 to 1/4 acre lawn, with annual mowing contracts for a quarter acre at $900 to $2,000 for 25 to 35 visits a season. LawnStarter, updated October 5, 2026, puts a typical visit at $42 to $68. Forbes Home and Bob Vila quote higher national averages, around $124 to $125 a visit, so the HomeGuide range is the conservative case for the robot.

## Robot vs lawn service: when the robot pays for itself

Against a mowing service, the cheap robots pay back fast. The Navimow i210 AWD at about $1,235 over 3 years costs less than two years of HomeGuide's low end quarter acre contract ($900 a year). At the high end of that range ($2,000 a year), it pays for itself in the first season.

Larger lawns make the case stronger, because service prices rise with size. HomeGuide lists weekly mowing at $50 to $75 a visit for half an acre and $60 to $100 for a full acre. At 25 to 35 visits a season, that is roughly $1,250 to $2,625 a year for half an acre and $1,500 to $3,500 a year for an acre. A robot rated for an acre, like the Navimow X430 at about $2,853 over 3 years, costs less than 2 years of the low end service price.

The catch: a robot only mows. HomeGuide prices edging at $0.50 to $1.00 per linear foot and leaf removal at $100 to $300 a visit, and a service often handles that trimming and blowing. Most robots leave some edge work. Tom's Guide found the Sunseeker S4 left an uncut strip along edges, while BGR found the Ecovacs GOAT A3000 LiDAR PRO's edge trimmer handled roughly 75 to 90% of manual trimming.

## Robot vs push mower: you are buying time, not saving money

If you mow yourself, a robot costs more in cash. HomeGuide puts the average gas push mower at $175 to $300 and a battery push mower at $200 to $500, with an 8 to 10 year lifespan. A push or self propelled tune up costs $45 to $75 a year. Even the cheapest robot here, the Navimow i206 AWD at about $1,035 over 3 years, costs roughly 2 to 3 times as much as a gas push mower over the same period.

What you get for the difference is your weekends. Forbes Home says mowing typically takes a pro 1 to 2 hours. At 25 to 35 mowings a season, that is roughly 25 to 70 hours a year. If you would pay to get that time back, the robot is worth it; if you enjoy mowing, it is not.

## Who a robot mower is worth it for

- You pay for mowing now. The 3 year cost of a matching robot is lower than 2 to 3 seasons of service in every lawn size above.

- Your lawn is between about 0.15 acre and 1 acre. That is the range our 12 listed models cover, from the 0.15 acre Navimow i206 AWD to the 1 acre Navimow X430.

- Your slopes fit the rating. Ratings run from 30% on the Worx Landroid Vision Cloud WR320 to 84% on the Navimow X430, and reviewers saw some fall short: Notebookcheck measured just over 70% on the Dreame A3 AWD Pro against an 80% claim.

## Who should skip it

- You mow yourself and do not mind it. A $175 to $300 gas push mower plus tune ups is far cheaper.

- Your lawn is over about an acre. The largest model in our list, the Navimow X430, is rated for 1 acre; bigger lots need a pricier model or more than one robot.

- Your lawn is mostly steep or soft. Gizmodo saw the Dreame A3 AWD Pro leave ruts and bald spots on damp slopes, and the Worx WR320 lost traction in thick edge grass in Bob Vila's tests.

- You have heavy tree cover and poor cell coverage, and you were looking at an RTK model. Pick a LiDAR model instead; see our RTK vs LiDAR guide.

- You want edging, leaf removal or fertilizing handled too. A robot does none of that, so you may still need a service for part of the year.

## Costs people forget

Blades are the main running cost. Ecovacs says to change GOAT blades every 4 to 6 weeks, Mammotion every 3 months or 150 hours, and Navimow every 2 to 3 months. That is why the GOAT A3000 has the highest blade bill in the table, about $390 over 3 years if it mows all year.

Some plans charge after year one. Navimow 4G data costs $32.90 a year after the first free year. Worx says its RTK Cloud service is free for life. Dreame includes 3 years of its link service but did not list the renewal price.

Batteries are an optional cost in year 3 or later. Navimow sells a replacement i2 battery for $159.99 to $199.99 and an X4 battery for $449.99. Warranties differ too: Husqvarna gives 4 years in the US and Canada, Navimow, Mammotion, Mova and Airseekers give 3, and Navimow covers its batteries for 2.

A boundary wire is no longer needed on any model in our list, which removes the old installation bill. If you are weighing a wired mower, see our boundary wire installation guide for typical costs.

## Questions people ask

### How long does it take a robot lawn mower to pay for itself?

Against a mowing service, often 1 to 2 seasons. A Navimow i210 AWD costs about $1,235 over 3 years, and HomeGuide puts a quarter acre mowing contract at $900 to $2,000 a year. Against a push mower you mow yourself, it does not pay back in cash.

### How much does a robot lawn mower cost to run each year?

Mostly blades. Over 3 years our data puts it at about $130 for the Husqvarna 410 iQ, $186 for the Navimow i2 AWD models including 4G data, and $245 to $390 for the Mammotion and Ecovacs models, assuming year round mowing. LawnStarter says charging costs only a few cents a session.

### Is a robot mower cheaper than a lawn service?

Yes over 3 years for most lawns. HomeGuide puts 3 years of weekly quarter acre service at $2,700 to $6,000, while the matching robots cost about $1,035 to $2,044 all in. A service also edges and blows, which a robot does not.

### Do I still need a trimmer with a robot mower?

Usually yes, for edges. Tom's Guide found the Sunseeker S4 left an uncut edge strip. The Ecovacs GOAT A3000 LiDAR PRO has a built in edge trimmer that BGR found replaced roughly 75 to 90% of manual trimming.
