The Ultimate Robot Lawn Mower Review

I’ve been planning on buying a robotic lawn mower this spring and I’ve been researching various mowers furiously.  Besides the coolness factor of these things, who wouldn’t want to buy something that mows the lawn while you do something else?

Because I’ve put so much time into this, I thought I’d make the ultimate robotic lawn mower review so that anybody else looking at these things wouldn’t have to repeat all the research I did.

So, here we go…

How Do Robot Lawn Mowers Work?

Robot lawn mowers don’t mow the lawn in the same way that you or I would.  If you didn’t know any better you would almost think they were mowing randomly.

However, there is a method to their madness.

When you first get a robotic lawn mower, you need to set up the perimeter of your lawn.  This means pegging a perimeter wire around the outside of your lawn and around any major obstacles in your lawn mower’s way.  Many robotic lawn mowers also allow you to set up different “zones” in your yard, which basically breaks your yard up in to different chunks.

Once the perimeter is set up, the mower takes care of everything itself.  It goes out by itself and mows until it needs to recharge.  It uses the wire around the perimeter to determine its location.

What Features Should I Look for?

There are a number of different features that different robot lawn mowers have.  In order to pick the best mower for you, it’s important to know what these features are.

  • Power – All robot lawn mowers are powered by batteries.  Some are charged up at a charging station that is connected to your home’s power outlet.  Others can be solar powered.  The type of battery can vary depending on the motor
  • Lawn Size – every mower is made for a maximum lawn size.  Popular lawn sizes are half acre, 3/4 acres and 1 acre.
  • Type of cut – most robotic lawnmowers are mulching, which means the grass is cut so that the clippings are very short and can be left on the lawn.  The main difference here will be the type of blade used.
  • Direction of travel – some mowers move around the lawn clockwise, others move around counter-clockwise
  • Pattern – some mowers mow randomly while others mow in a pattern
  • Zones – mowers have different number of zones that can be programmed into the robot.
  • Safety – most robot lawn mowers have sensors to tell it if it bumps into things.  Most of them also have tilt sensors that turn the mower off if it flips over.  I recommend not buying a mower if it doesn’t have safety features like this

Who Makes Robotic Lawn Mowers?

There are a number of companies that make robotic lawn mowers.  Some of the major brands are Lawnbott, Robomow, LV Robot, and Wolf Garten.

Lawnbott LB1500 SpyderEVO Review

lawnbott-LB1500The Lawnbott LB1500 SpyderEVO is a great mower to use for smaller yards.  It uses wire and pegs around the perimeter of your lawn.  It comes with 300 ft of wire and 200 pegs.  This is generally sufficient for yards that are 10,000 sq. ft or less.  It weighs about 25 lbs.The LB1500 is very easy to use.  Once the perimeter wire is installed, all you have to do is press start and it will start mowing automatically.

There is no display on the LB1500.  Instead, the mower uses beeps to communicate what mode it is in.   Safety features on the mower include touch sensors on the handles that automatically stoop the blade or the wheels.

The LB1500 is very quiet, especially compared to traditional internal combustion engine lawn mowers.  The manufacturer claims the mower can run at night without disturbing neighbors.

The LB1500 uses a lithium ion battery, which makes it very light compared to a lead acid battery.

One downside to the Lawnbott LB1500 is that it only has one mowing zone.  This means that if you have more than one section of lawn you will probably have to manually move the mower from section to section.  More advanced mowers can do this automatically.



Lawnbott LB3510 Review

lawnbott lb3510The Lawnbott LB3510 is the perfect mower if you’ve got a larger yard.  This mower is made for yards with a maximum size of 1.5 acres.  It comes with 660 ft of wire and 200 pegs to allow you to stack out the entire outside of your yard.  Like the other robotic mowers in this post, the LB3510 is meant to keep the grass looking like it was just mowed.

This mower is powerful enough to work on slopes that have an incline of up to 25 degrees.   The manufacturer recommends not mowing grass that is any longer than 4 inches long, but I’ve heard of people have had no issues mowing much longer grass.

It uses a back lit, 2-line LCD screen to display information and to allow you to easily program the mower.  The LB3510 can handle up to 4 zones or areas of the yard.  The mower will follow the perimeter wire until it reaches the zone it needs to mow and then mow that area.  If it finishes before the batteries are low, it will move on to the next zone.

One of the great things about robot lawn mowers like the LB3510 is that because your lawn is mowed from all different directions, the quality of the cut is very good.

The safety features of the LB3510 are similar to the safety features found on the LB1500.  There is a sensor on the handle that sense when it is touched and automatically shuts off the mower blade.  There is also a “tilt” sensor that will shut off the blade if the mower flips over.



I plan to keep adding mowers as I research them.  I have plans to review lawn mowers for LV-Robot,  Robomow and Wolf Garten.  If you are interested in any of these, click the links below and they will take you to the Amazon page for each of those companies.
