Frequently Asked Robot Lawn Mower Questions

Frequently Asked Robot Lawn Mower Questions

Reading Time: 7 minutes.

This article is my attempt at documenting my experiences with Worx Landroid L2000. It’s a phenomenal little helper in your garden, but it will run into issues – and it’ll make you work a bit in order to get it to run efficiently!

This article contains all of the gotchas I’ve run into so far, wrapped in a handy FAQ-format for your convenience (and mine, to be fair – I’ll be back to consult my notes later)!

Most of the points should apply to a lot of other robot lawn mower models.

While my experiences come from 2 Worx Landroids, I suspect most of these apply to any low to mid-high -range autonomous mowers out there. The cream of the crop will probably behave differently, so if you’re buying one of the more expensive Husqvarnas, you’ll probably need to learn to live with your decisions without my help.

How thick a stick will the robot cut?

This probably depends on a lot of things, but the thickest my Landroid L 2000 has been able to cut, was about a centimeter in diameter.

That’s roughly 100 mickeys, 4.5 potrzebies or 2/5 of an inch, for those of you preferring imperial units.

It’s.. A lot. Far more than I expected.

But generally speaking, you shouldn’t expect a robot to do more than what a weed whacker can do. Cutting thick wooden things will have a detrimental effect on your robot’s blades really quickly!

Are steep hills a problem?

I’ve mentioned this before, but at least my Landroid manages hills and slopes well. However, there’s a couple of things you need to do to avoid issues.

If your grass is already tall, your robot might get stuck when trying to go uphill. In case the hill is close to the border of your lawn, the robot might (quite comically) just slide off the lot and freeze. These, and all other problems, are made worse when it’s wet outside!

And obviously, different devices will have different maximum grades they can navigate. Some AWD models claim they can do over 40 degrees!

How many times can I extend my boundary cable?

There shouldn’t exactly be a limit – but at some point, the base will run out of juice providing the electric current for the wire, especially with many connectors.

If you buy high-quality connectors, you should be good.

How can I join 2 parts of my boundary cable?

Theoretically, any adapter that’ll let you join 2 cables should do. For whatever reason, most autonomous lawn mowers seem to come with Scotchlock 314 -typed splices adapter… Which shouldn’t be required. But since it’s what the manufactures seem to prefer, I used them.

Well, I used a generic version – the original ones cost 2-3 € each, so I ordered a bunch of genuine Chinese copies, and they work just as fine and were in fact easier to install. So that’s good.

If I define “zones” for my Robot Lawn Mower, will it stay in the zone for the whole runtime?

The most expensive robots should. For the mid-high range (such as my robots, Worx Landroid L 2000), you typically get to only define a starting point, and the rest is up to the form of your lawn.

You might, for example, have multiple sectors or parts of your lawn connected by a “corridor” – a narrow strip of lawn, where the boundary wire doesn’t quite connect, but rather lets the robot through. That way you might want to define first part of your lawn as Zone 1, and after your robot has followed the boundary wire to the second part, you could define that as Zone 2.

Unfortunately, most mid-high -range robots also come with some smart algorithms for traversing corridors. My Landroid is exceptionally good at escaping one sector of my lawn, since I have a corridor that’s about 50 cm wide (that’s about 1/9 of the height of a double-decker bus for you imperialists out there!) – and it’s easily able to slip through.

Mowing lawn even when it rains

I don’t like cutting grass in general, but I especially dislike it when it rains! But a robot doesn’t really care. A lot of the robot lawn mowers on the market now are perfectly able to cut damp grass and don’t really mind getting wet, as far as they don’t get stuck in the mud!

But there are some caveats – depending on the model, the robot’s likelihood of getting stuck or obstructed will either increase or skyrocket when the conditions get worse!

Can I have multiple robot lawn mowers mowing my lawn?

On separate sectors, yes, but if they share a border, you’ll run into weirdnesses.

At least with Landroids, the boundary cable only has electricity running through it when the robot is out and about. This means, that whenever it’s at home, the boundary cable is invisible to other robots out there.

This is primarily a good thing.

If you have your Landroids running at the same, you might experience one of 2 sorts of interference whenever they reach the boundary with 2 adjacent cables for different bases:

1) Your Landroid might sense both cables but realize they’re close enough to be crossed. Now you have 2 Landroids mowing an area where you should only have one, and when either one of them gets tired and goes home, the other one will wander off and possibly never be found again.

2) Your Landroid might sense both cables but be unsure why their frequencies don’t quite match. Poor little robot will stay confused until it runs out of battery, or the other robot goes home and the other boundary wire turns off.

Your robot might also just act normal – this is the case, if the wires are far enough (20-something-plus cm) from one another.

How should I clean my robot for the winter?

Use pressurized air, and if need be, a brush or towel.

Don’t use a garden hose, and don’t even think about using a pressure washer.

Will my robot kill a puppy if it gets a chance?

Unfortunately, I’d keep puppies as far from the robots as I can. While they’re relatively good at recognizing objects and either bumping into them softly or avoiding them altogether, you should not trust this.

Have your robots mow your lawn overnight and teach your puppies to stay away from it, just in case.

And don’t attach lasers to an autonomous robot with artificial intelligence. It’s not smart.

How do I send the Landroid home if it’s complaining about low battery?

The message about low battery looks something like this:

! LOW BATTERY !
CANNOT START

But it’s actually misleading. You can send the Landroid home by pressing the Home/Charge -button, and then “OK” once or twice.

And added bonus is that your Landroid will actually have the blades running, when sent home this way.

How do I force Worx Landroid to do an edge trim?

Worx Landroids have a great feature called border trim, edge cut, edge trim, border cut or boundary cut (or whatever it’s called – it has multiple names in the documentation and the app!) Like the name implies, the robot will simply follow the wire to cut the edges of the lawn.

This not only makes the lawn look good, but is also imperative to ensure the little robots gets home after it’s shift!

However, you can only schedule a run like this to happen once a day, and neither the app, the API or the device itself has a way to command an edge trim.

There’s a workaround, though:
Send your Landroid to work, then STOP it, direct it towards the boundary, and hit Home/Charge button once, and “OK” once (or occasionally twice).

Your Landroid will head to the boundary, then follow it home with blades running.

My Landroid is struggling to stay on WiFi. What do?

First of all, make sure you’re exposing 2.4GHz WiFi frequency for your robots, as that’s what they’re using! But additionally, it seems like whatever network card these devices are using, it’s pretty aggressive in entering powersaving mode and it drops off the network.

If the robots are on the fringe of your network, opening the app and trying to update the status of your robot might not work – Landroid Cloud pinging your robot simply doesn’t get through. However, it seems like having a device constantly maintaining the connection to the robots will counter this issue.

For me, that device would be Home Assistant, but you’d probably be fine just having the Landroid app in a smartphone without battery-saving features enabled.

Does a robot lawn mower take care of raking in the fall?

No. Most likely, it’ll shred some of the leaves just fine, but largely just spread them around a bit.

This list is unfinished for sure. But it’s all I had for now! Whenever I find something new, I’ll be sure to update it.
