Factors You Should Consider When Buying a Robotic Mower

Advancement in technology has seen upgrades of many machines that we use in our daily schedules. The lawn mower has not been left behind. Modern lawnmowers come with advanced tech features that allow remote operation. You may then mow the lawn while sipping a drink on the comfort of your couch. Artificial intelligence and wireless connectivity allows you to configure and run the robotic mower on your phone or tablet.

In the following sections, we have listed some of the aspects that differentiate robotic mowers from each other. If you are on the lookout for a robot mower, these criteria will help you select the best robot lawn mower for hills.

How the Mower Handles Different Terrains

robotic mower hills slopes rough terrain performance

The simplest grass to cut is a flat lawn, but more often than not your lawn will have obstacles and varied gradients in different parts. Since a robotic lawn mower operates autonomously, you must check how it adjusts when it encounters a slope or terrain alteration.

If your yard is steep, we recommend you pay attention to the size of the wheels. When the mower goes up or down a steep slope, the big wheels come in handy.

Ease Of Use

The mower you’re buying should be easy to set up and use. Most robotic mowers today come with wireless and Bluetooth connectivity, allowing them to be operated from smart devices.

The control panel should have just the right amount of configuration options to enable you to effectively manage the mower. Too many buttons and settings can lead to you taking a long time before you know how to set the mower properly while limited options leave you with little room to suitably set up the mower.

Cutting Height Adjustment

Robotic mowers that connect wirelessly to your mobile devices let you adjust the cutting height right from the app. The robotic mowers that do not connect to smart devices have buttons on them that you can use to configure cutting height adjustment before you set them to mow your lawn.


robomower reliability automatic recharging

The benefit of acquiring a robotic lawn mower is to have a tool that maintains your lawn with little intervention required from you. It is not always certain, though, because even the top of the line mowers sometimes get jammed.

A reliable robot mower should do the job without getting stuck frequently. The mower should also cover most of the lawn and get through to the areas around obstacles and narrow pathways.

Robotic mowers are costly machines. Most manufactures cover their devices under limited time warranty during initial purchase to attract customers. Once the warranty period expires, you will need to pay for any repairs made to the mower.

Therefore, you probably should think about buying a mower whose body can withstand the harsh weather outside. The body should also cover the delicate interior parts inside the mower to prevent water from reaching and damaging the circuit boards that enable the robotic mower to operate.

Cutting Width

Much like the push behind and riding lawn mowers, the cutting width of the robotic mower determines the number of passes that the mower has to take to cover the lawn. The mowers with wide cutting decks have to make fewer passes than the mowers with narrower cutting decks.

Wide cutting decks on robotic mowers also help to stabilize the mower and reduce the chances of the mower toppling over.

Mowers with wider cutting decks tend to be a little more pricey. This is attributed to the advanced engineering used to fit the wider deck on the mower. The wider robotic mowers, however, could make it difficult to cut around obstacles and narrow pathways.

How To Prepare Your Lawn Before You Use a Robotic Mower To Cut the Grass On It

Before you can send out your robotic mower to take care of its mowing duties, you have to set the boundaries for where it should operate. This is accomplished using a wire which defines the edges. When the robotic mower reaches this edge, it stops, turns around, and heads in a new direction.

Defining boundaries is critical when using robotic mowers as it restricts the mower from moving beyond your lawn and into the neighboring yard. Boundaries also protect the mower from collisions with barriers and various objects in the yard.

Check out the instructional video linked below, which gives guidelines about how to properly set up the boundary wire for a robotic mower.


All the robotic lawnmowers we included in this review really impressed us. However, the Husqvarna AUTOMOWER 315X stood out as the best robot lawn mower for hills due its fair pricing and variety of features that it packs.

We particularly like the hands-free operation that is supported by voice activation and control. The other mowers in this review lack this feature but most of them support smartphone integration, which is equally useful. The Husqvarna AUTOMOWER 315X supports mowing on lawns with inclination of up to 22 degrees, which was not the steepest but capable of covering the lawns in majority of homes. Customers with steeper lawns can opt for the 435X AWD, which mows steeper lawns but costs a little more.
