ZDNET’s key takeaways
- Your yard issues greater than the robotic mower’s model.
- Navigation kind could make or break a robotic mower.
- Match the mower to your terrain, price range, and obstacles.
A robotic garden mower is kind of an costly buy, and one which should not be made evenly. There are a number of elements to contemplate earlier than you select a robotic mower, past the model’s claims of holding your yard trim and tidy. Out of your yard format to the navigation kind, robotic garden mowers aren’t created equal.
I have been testing robotic garden mowers for about three years now, since they turned extensively common. In that point, I’ve discovered the ins and outs of how robotic mowers function, what units them aside, and what you want to know earlier than committing to a mannequin.
How to decide on the proper robotic garden mower
Robotic garden mowers are designed and constructed for very particular functions and circumstances, so it is not a one-size-fits-all resolution. I am going to go precisely what is going to allow you to decide if a particular mannequin is true on your yard, so you may contemplate this a guidelines.
It isn’t concerning the mower, it is concerning the yard
The TL;DR is the kind of yard you might have at residence will decide the robotic garden mower you select.
Do not marry a model or mannequin merely since you’ve heard good issues about it — be certain it is a good match on your circumstances first. You’ll be able to select the proper robotic garden mower on 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 developed with the assistance of synthetic intelligence (AI), improved processors and sensors, and extra succesful algorithms.
Listed here 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 one of these 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 affords dependable navigation. It is also turn 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 stick with a map, which is a greater possibility 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 now not require a separate antenna. This transformation 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 a substitute 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 will be the most costly 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 reply to its environment in actual time. Such a “drop-and-mow” navigation tech is the best to arrange of all, because it sometimes solely requires plugging within the mower and including it to the app to map your yard.
- Execs: With out a wire or an antenna, these robots are inexpensive 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, similar to backyard beds.

2. Value and price range
Your price range can considerably slender down the listing of robotic mowers you select. Take into account when a robotic garden mower is smart, like whenever you already pay for garden service for a medium or giant yard, and when it could not, like if in case you have a small garden and truly take pleasure in chopping it.
A robotic garden mower will 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 completely 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 dimension that, mixed with the chopping width, ought to be capable to cowl an space inside a day’s work.
Discover out the scale of your lot, not your house’s footprint, to find out which robotic mower is finest for you. Most US suburban residence heaps are 0.25-0.5 acres. The lot dimension on your house is listed on land surveys, however you can too search for your house handle on actual property websites, like Zillow and Realtor. These websites embody the house’s acreage within the description, which is beneficial if you happen to’re a renter.
Listed here are a few of the top-performing fashions that I like to recommend in every dimension 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 wherein robotic mower you purchase. Hilly terrain generally is a large problem for robotic garden mowers and can possible 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 effectively on principally flat lawns:
Uneven terrain
A yard with a number of slopes, bushes, and general 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 possibility that works on tough terrain:
A number of sections in a yard
Whereas robotic mowers work finest in a single steady house, many yards have a number of sections. Listed here are some examples of robots which have executed effectively 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 finest suited to you.
For instance, a LiDAR robotic mower can do a adequate job of navigating your yard, but it surely will not be splendid for yards with out fences or for yards with backyard beds with out bodily borders. Some LiDAR fashions will stick with your map, however one of these navigation is not as dependable as wired boundaries.
Yards with out many obstacles, like rocks, bushes, toys, pets, and backyard beds, do effectively with most kinds 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… | It’s best to select… |
| Lots of bushes | A LiDAR or wired boundary mower, since bushes 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. Should you select a wired boundary, you might 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 finest, however an ideal GPS/RTK robotic mower can stick with the map you make with it. |
| Children 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 critiques and what customers say concerning the apps that management them earlier than trying out your on-line cart.
From the setup, mapping, and set up to the appliance, upkeep, and distant operation, any robotic garden mower you select should match into your routine and your stage of tech-savviness.
The extent of involvement you need in your robotic mower’s upkeep will largely rely in your alternative. You will have to exchange the mower’s blades each one or two months, relying on utilization. It is also necessary to wash your mower a couple of instances per season, with some fashions permitting you to make use of water hoses to take action.
