Best Robot Lawn Mowers for Hills & Slopes: Buying Guide
There are several factors to remember while looking for the best robot lawn mowers for hills and slopes.
Slope Inclination Capacity
Since you are looking at the best robot lawn mowers for hills and slopes, in particular, you will certainly need to consider how much of an inclination your mower can handle and manage.
This will then ensure that your mower does not stop in the middle of a steeper slope. Out of my three picks here, the best capacity is 45%, which belongs to Worx and Husqvarna.
However, all three options here were designed to mow decent-sized hills and slopes of 8.5% to 45%.
Size of Your Yard
Another important factor you must consider is how many acres your lawnmower can cover. This, of course, depends on the size of your own lawn.
My picks here are ideal for ½ to ¾ acre lawns.1/2 acre mowers will also handle smaller lawns nicely. If your lawn extends beyond 1 acre, you may want to consider other options for larger-sized yards.

Battery Life
How long your mower’s battery can run, and its capacity also has quite a bit of an influence on the efficiency of your lawnmower. Generally, it might be a good idea to go for newer models as these usually perform better.
A similar consideration here is how long the battery will take to recharge. In the case of robotic mowers, they automatically go to their charging stations once they sense that they are running out of battery. Once they are there, they might take a certain amount of time to charge, which could be anywhere between an hour to two hours.
Blades
Different brands of the best robot lawnmowers for hills and slopes use different types of blades.
Some blades are ideal for some types of grass than others. Consult the manufacturer specifications for the types of blades that are ideal for your lawn.
A standard number of blades that mowers generally tend to have are two to three.
Typically, they have individual motors to control and power each blade. They must also be sharp enough to cut through all kinds of lengths and widths of grass while also dealing with weeds and other dirt.
Consult your user manual for the mower to determine how long you need to change, repair, and clean them. Some blades are hot-swappable, extending their life.
Connectivity
Some of the best robot lawn mowers for hills will come with several other features that will allow you to control their functioning.
For instance, connectivity features such as smartphone apps, Wi-Fi or cellular connections, Bluetooth connectivity, voice controls, and more can enable you to monitor and customize the settings of your mower remotely.
Weather Protection
Additionally, most of the best robot lawn mowers for hills and slopes now come equipped with weather protection that can allow them to survive in harsh weather conditions as well or to detect changes in weather so that they can make their way to their stands.
GPS tracking and security features keep your mowers safe from theft as well.
Warranty
The warranty period for the best robot lawn mowers for hills and slopes will help you out when it comes to repairs, replacements, and refunds. Ideally, the warranty period should be over two years so that you can easily replace necessary parts at no cost in that period.
All the best robot lawn mowers for hills and slopes mentioned here have this minimum warranty period, with the WR155 having a period of three years.

FAQs
In this section, I will try to answer some frequently asked questions about the best robot lawn mowers for hills and slopes.
Are the Best Robot Lawn Mowers for Hills and Slopes Safe?
One of the most common questions about these machines is whether or not they are safe for pets and small children.
While some brands do have safety features, like built-in child sensors, it’s always best to supervise your kids and any pets while using one of these machines so they stay out of the mower’s way.
Are There Separate Accessories That I Will Need?
Yes and no. Most mowers come with everything you will need to get started, including a battery, boundary wires, covers, some extra blades, screws, wires, plugs, adapters, and other tools.
However, the specific accessories robot mowers ship with vary from manufacturer to manufacturer. If you haven’t thought about where you will be storing your mower, you might want to purchase a separate “shelter” to house the vehicle in between mows.
How Often Should I Replace and Clean the Parts Of My Robotic Mower?
You will find all the maintenance information specific to your mower in your product manual.
However, a good thing to remember is that you should regularly clean blades and wheels whenever you see them full of dirt and grass. In particular, if you notice your mower moving sluggishly or stopping, this is likely a sign that it is time for cleaning.
The same applies to replacing parts, especially if you notice damage to a specific part of your mower.
What Is a Boundary Wire?
A boundary wire, as the name suggests, is a long wire that you must install along the edges of your lawn so that your robotic mower knows when to turn back or move on to another area. This can be a good way of keeping your mower inside the confines of your lawn.
This can be particularly helpful if you have a sloped or hilly lawn, as it can be easy for you to lose sight of the mower. By fixing a wire in place, you can prevent the mower from moving beyond a certain point. This can prevent the loss of the device as well.
