5 Best Robotic Lawn Mowers 2021

Technology just keeps getting more advanced. Cars are driving themselves and so can lawn mowers. Read below about the latest trends and let us help you find the best robotic lawn mower that exists today.

These phenomenal devices are not cheap, but just imagine the time savings that they give. As I investigated the history of these automated mowing machines, I was amazed to learn that they were first patented in 1969.

All the robot lawn mowers we reviewed had some basic features in common. They change the way you care for your lawn. Rather than mowing when the grass gets too high, the robots are designed for continual lawn care.

The will run several times a week during the growing season. This makes their job easier so they do not have to worry about cutting long grass. This also makes them more reliable. They drop short pieces of cut grass into your yard for nourishment.

They will NOT mow your yard in an organized pattern. Rather, just like the indoor vacuums, they will wander randomly around your yard. With the frequent mowing, they will be able to visit all areas of your lawn and keep it look sharp.

If you are someone who likes to see nice mowing patterns at the end of a mowing session, then these will not work well for you. The combination of frequent mowing sessions and random pattern will keep you lawn looking uniform throughout the year.

Reliability of Robotic Mowers

They all have a base station to which they return after each cutting session. They will charge and be ready to work again. The base station will be along the laid out perimeter, in the shade, and will power available.

You lawn will really determine how successful your robotic mower will be. A flat yard few obstructions will certainly be best. Also, it seem that the boundary wire will need to be installed at a nearly flat area.

These mowers run very slowly, like 1 mph. Since they are all designed to run unaccompanied this will work out fine. Just do not expect really quick work of you yard.

Before you can use your robotic mower, you will set up a wire boundary that will define the area that the mower will stay within. This is much like a dog fence. The wire and attachment stakes are included. I’d suggest using a manual edger to set the wire into the ground where you will not need to worry about it again.

Lots of advanced features are included

These are pretty high tech devices and pretty costly as well.


Most of these mowers directly communicate with an app so you can keep track of their progress. They may have WiFi, Bluetooth, or Cellular connections. Or, in the case of one unit, no communication at all.

Some are also GPS enabled so you can know if they have gone missing.

These mowers have logic to try to get themselves out of tight situations. They will back up and spin as they try to get free. Occasionally though, they will get stuck. At that point, they will shut down and notify you of their problems.

Mowing Pattern

Most of the mowers to designed to run fairly frequently to keep your yard always nicely manicured. They run a random pattern that over time statistically covers your whole yard.

It may not seem like a random patter will work, but it does.

Mower Specifications

Runtime: These are battery-driven mowers and will have the clean running benefits of all battery mowers. The size of the battery will determine the runtime and size of the yard that they can adequately handle.

Maximum Incline: The mower designs allow for different levels of hilly yard handling. The less expensive models will do better on a flat yard and the more expensive ones are listed to handle up to 24 degrees of incline. 24 degrees is a steep slope!

Safety: The mowers are designed to stop the blade if picked up or the wheels otherwise are not in contact with the ground. You should not have to worry too much about safety. I assume that cats will stay away and dogs will learn to ignore the mowers.

Other considerations

If you do have dogs, you probably have fences. These are going to be a bit problematic for your mower. If you just want to mow the enclosed area, you will be fine. But, if you have an enclosed rear yard and open front yard, you will have to arrange to get the mower into the front yard because it will not be able to open the fence gate.

Also, dog poop can be a bit of a messy problem. The mower is not going to avoid the “doggy dirt” and it is going to get all over things. It is highly recommend that you pick up before turning the robot loose.
