I have been testing robotic garden mowers for about three years now, since they grew to become broadly common. In that point, I’ve realized the ins and outs of how robotic mowers function, what units them aside, and what it’s essential know earlier than committing to a mannequin.
How to decide on the suitable robotic garden mower
Robotic garden mowers are designed and constructed for very particular functions and circumstances, so it isn’t a one-size-fits-all answer. I will go precisely what’s going to allow you to decide if a particular mannequin is correct to your yard, so you may take into account this a guidelines.
It isn’t in regards to the mower, it is in regards to the yard
The TL;DR is the kind of yard you have got at dwelling will decide the robotic garden mower you select.
Additionally: I let a smart planter maintain itself for 2 months – here’s the result
Do not marry a model or mannequin merely since you’ve heard good issues about it — be sure it is a good match to your circumstances first. You may select the suitable robotic garden mower to your yard, however you may’t make your yard work with simply any robotic.
1. Boundaries and navigation
Robotic garden mowers use various kinds of navigation expertise which have advanced with the assistance of synthetic intelligence (AI), improved processors and sensors, and extra succesful algorithms.
Additionally: This 3-in-1 adapter for the Starlink Mini made all the difference for its power delivery
Listed below are the various kinds of navigation that robotic mowers use:
Wired boundary
A robotic mower with a wired boundary is the oldest navigation expertise for the sort of machine. With this expertise, you bury a boundary wire across the perimeter of your garden. The robotic mower is engineered to not cross this wire, so it stays inside that bodily boundary.
- Execs: The bodily boundary presents dependable navigation. It is also develop into cheap as different applied sciences have grown extra common.
- Cons: Organising a boundary wire is labor-intensive in contrast with different choices.
Finest wired boundary robotic mowers:
GPS/NetRTK navigation
Some robotic mowers use satellite tv for pc navigation to create and persist with a map, which is a greater choice for bigger yards than wire boundaries. Whereas GPS/RTK robotic mowers initially used an antenna for satellite tv for pc connectivity, newer NetRTK expertise means robots not require a separate antenna. This modification simplifies the robotic mower’s setup course of.
NetRTK makes use of a community of fastened GPS stations to assist the robotic make fast corrections and keep a map’s accuracy inside a few inches. As an alternative of counting on a single GPS base antenna, NetRTK makes use of a number of stations to cross-check the robotic’s location in actual time.
- Execs: GPS antennas aren’t as labor-intensive to arrange as wired boundaries. Newer fashions do not require antennas.
- Cons: Whereas setup is simpler, GPS/RTK antennas require a comparatively clear view of the sky and could be the costliest navigation kind.
Finest GPS/NetRTK robotic mowers:
Visible navigation
The most recent navigation expertise for robotic mowers combines LiDAR sensors, cameras, and AI algorithms to allow the robotic to answer its environment in actual time. Any such “drop-and-mow” navigation tech is the best to arrange of all, because it usually solely requires plugging within the mower and including it to the app to map your yard.
- Execs: And not using a wire or an antenna, these robots are cheaper and simpler to arrange than GPS and NetRTK fashions.
- Cons: This expertise continues to be evolving, so it’s possible you’ll encounter points with the robotic drifting out of your yard or into areas it should not go, resembling backyard beds.

2. Worth and price range
Your price range can considerably slender down the record of robotic mowers you select. Contemplate when a robotic garden mower is sensible, like while you already pay for garden service for a medium or massive yard, and when it could not, like when you have a small garden and really get pleasure from chopping it.
Additionally: Looking for a no-sub security camera? Here’s one I recommend (and it’s on sale)
A robotic garden mower could be budget-friendly ($500-$1,000), midrange ($1,000-$2,000), or premium/high-end ($2,000-$6,000).
3. Measurement of your yard
Robotic mowers are designed with totally different specs to cowl a decided acreage in a single day. That does not imply they will do it on a single cost, however every has a sure battery measurement that, mixed with the chopping width, ought to have the ability to cowl an space inside a day’s work.
Discover out the scale of your lot, not your property’s footprint, to find out which robotic mower is greatest for you. Most US suburban dwelling heaps are 0.25-0.5 acres. The lot measurement to your house is listed on land surveys, however you too can search for your property handle on actual property websites, like Zillow and Realtor. These websites embody the house’s acreage within the description, which is beneficial should you’re a renter.

Listed below are a few of the top-performing fashions that I like to recommend in every measurement class:
0.10-0.25 acres
0.25-0.75 acres
0.75-1.25 acres
4. Yard terrain
As I discussed above, the way in which your yard is constructed would be the figuring out issue through which robotic mower you purchase. Hilly terrain generally is a massive problem for robotic garden mowers and can doubtless require a mannequin with all-wheel drive, for instance.
Flat or gently sloped yards
Many cheap robotic mowers are well-suited to deal with flat and even gently sloped yards. These robotic mowers carry out properly on principally flat lawns:
Uneven terrain
A yard with a number of slopes, timber, and total tough terrain requires a mower that may deal with unevenness with out sliding or getting caught. A number of areas in my yard have proved difficult for a number of robotic mowers, however here is an AWD choice that works on tough terrain:
A number of sections in a yard
Whereas robotic mowers work greatest in a single steady house, many yards have a number of sections. Listed below are some examples of robots which have completed properly in my sectioned yard:
5. Obstacles
The obstacles in your yard will help slender your selections for a robotic mower, as they largely decide the kind of navigation greatest suited to you.
For instance, a LiDAR robotic mower can do a ok job of navigating your yard, nevertheless it will not be preferrred for yards with out fences or for yards with backyard beds with out bodily borders. Some LiDAR fashions will persist with your map, however the sort of navigation is not as dependable as wired boundaries.
Yards with out many obstacles, like rocks, timber, toys, pets, and backyard beds, do properly with most forms of robotic mowers, supplied that they’re suited to deal with the terrain accordingly.
Contemplating obstacles, here’s what I like to recommend:
| For yards with… | You must select… |
| Numerous timber | A LiDAR or wired boundary mower, since timber can intrude with satellite tv for pc indicators. |
| Unbordered backyard beds | A GPS/RTK robotic mower that you would be able to set as much as keep away from flower beds when mapping. |
| Backyard beds with borders | A LiDAR, GPS, or wired boundary robotic mower works for these yards. In the event you select a wired boundary, you will have to bury wire across the flower beds, until the borders are tall sufficient for the mower to keep away from. |
| No fences | A wired boundary is greatest, however an awesome GPS/RTK robotic mower can persist with the map you make with it. |
| Youngsters or pets | A LiDAR robotic mower that may alter its navigation in actual time in response to its environment. |
6. Ease of use and upkeep
How straightforward your robotic mower is to make use of and keep is essential when selecting a mannequin. Most individuals who purchase robotic garden mowers desire a machine that makes the grass-cutting activity simpler, not more durable. Analysis the mower’s opinions and what customers say in regards to the apps that management them earlier than testing your on-line cart.
From the setup, mapping, and set up to the applying, upkeep, and distant operation, any robotic garden mower you select should match into your routine and your stage of tech-savviness.
Additionally: This power station kept my fridge running during an outage (and just dropped by over $1,000)
The extent of involvement you need in your robotic mower’s upkeep will largely rely in your alternative. You may have to switch the mower’s blades each one or two months, relying on utilization. It is also essential to wash your mower a number of instances per season, with some fashions permitting you to make use of water hoses to take action.
