4. McCulloch R600 Cordless Robotic Lawnmower

Best robot lawn mower for irregular shaped lawns: handles tricky spaces so you don't have to

Specifications
Best for: Irregular shaped lawns
Battery life: 65 mins
Charging time: 50 mins
Lawn size: 600sqm
Cutting width: 17cm
Reasons to buy
+Can handle up to 25% slope+Collision sensors and boundary wires+Feeds the lawn
Reasons to avoid
-Sizable investment for an app-free model

Wiring
The McCulloch R600 is one mighty machine – just what you need to cope with gardens that have a challenging layout. Amazingly, this lawn mower lays down boundary wires as it works its way around the perimeter of your lawn; these disappear into the ground after a few weeks and won't be noticeable.

Collision sensors
You'll never have an issue with this mower bumping into trees or edges thanks to its sensitive collision sensors. The McCulloch also can tackle sloping gardens, coping effortlessly with inclines of up to 25 per cent.

Easy setup
The set up and operation is pretty fuss free with this model which has an integrated LCD display and controls for operation. This is one place it falls short of other models – it is easy to control, but with no app functionality you don't get to program cutting schedules like you do with some of the more affordable models in our list. However, if you like simple push button autonomy, this is for you.

5. LANDXCAPE LX799 300m2 Robotic Mower

The best budget robot lawn mower

Specifications
Best for: Affordability
Battery life: 60 mins
Charging time: 240 mins
Lawn size: 300sqm
Cutting width: 16cm
Reasons to buy
+Affordable price+Easy to start
Reasons to avoid
-Not Wi-Fi enabled-Long charge time

Even a small lawn can take time to mow, so if you want to remove the faff of getting the mower out, but don't have much budget, the LANDXCAPE LX799 is a great option.

Mowing tech
With a 16cm cutting width and a cutting height of 20 to 50mm, this LANDXCAPE mower can tackle gardens with a 15˚ incline. The patented mowing technology built inside this lawnmower enhances its efficiency by 30 percent, while it uses both forward and reverses rotations in order to reduce the wear of the blade by half. There's a three-blade cutting/mulching system meaning that similar to other robot lawnmowers, it cuts the grass and disperses it back into your lawn to be used as a fertilizer.

Ease of use
This robot lawnmower is better for smaller gardens – up to 300m2 – and it will take itself home when power is low. It also doesn't need to be programmed and will start mowing at the press of one button. It has bump sensors so as not to hit your furniture (or the kids' climbing frame), while the robot will navigate away from narrow or tricky paths, too. Though not Wi-Fi enabled, it's very easy to use as it features a keypad on the top of the device.

Safety
The LANDXCAPE mower requires a PIN code to work – this will protect the lawnmower from unauthorized activation. If the mower is picked up, its blades will stop moving immediately.

6. Ambrogio L60 Deluxe Automatic Robotic Self-Propelled Lawn Mower

The best robot lawn mower for sloped gardens: steep lawns are no problem for this clever buy

Specifications
Best for: Sloped gardens
Battery life: 120 mins

Lawn size: 200sqm
Cutting width: 25cm
Reasons to buy
+No wires needed – grass sensors keep the mower on the lawn+Long battery life+Lightweight+Will handle slopes of up to 50 per cent
Reasons to avoid
-Very expensive considering it is better suited to smaller lawns

Have slopes and complex lawns that you don't want to set up wires round? The Ambrogio L60 Deluxe is the most convenient of robot mowers when it comes to getting started.

Great for sloped gardens
A deluxe lawn mower indeed, the Ambrogio L60 will safely and reliable tackle pretty much any garden, including a steeply sloping one – it will confidently climb up an incline of up to 40 per cent with a maximum permissible slop of 50 per cent.

Grass sensors
Intelligent grass sensors ensure that this mower always stays on the grass, never ending up on a path or drive – without the need for wiring. It's lightweight, too, which makes picking it up when it's done no problem at all. 

Expensive
All this clever design comes at a steep price, though, so it only worth it if you do have a sloped garden. However, if you have the cash and want a mower that won't require hands on set up, then it is worth the money. It is also great for fiddly layouts with lots of slopes.

Batteries may need replacing soon
The batteries are perhaps not the best, though, so be prepared that you might need to replace them after a while. 

What is the best robot lawn mower?

We love the Flymo Easilife 200 robot lawn mower as it is easy to use and very affordable considering its range of features. However, this is probably best suited to small urban lawns so if you need to cover a bit more ground we think the Worx Landroid M500 is the best balance of price and function.

How to buy the best robot lawn mower

Connectivity
When buying a robot lawn mower, it's good to check out what connectivity features it has. Can be linked up to an app on your phone, and if so, how many features does it have apart from on and off? Some of the best robot lawn mowers will have connectivity features like remembering the layout of your lawn and when it needs cutting. However, as we know this isn't for everyone, we have a couple of models that are set up and go, meaning you put the boundary wire in place, connect to the docking station and press a button on the mower to start it. They are intelligent enough to work out their course and this might suit people who find app control actually more complicated.

Battery life vs. charge time
As with any other type of cordless lawn mower, a robot mower will only run for so long continuously before it'll need recharging. Think about the size of your lawn: smaller lawns can be covered in about half an hour, but a larger lawn will need 45 minutes and longer. Also look out for smart robot mowers that will return to their docking station without you needing to remember to recharge them. This can get round the issues of a shorter battery life as they will automatically recharge, but does mean the job can take longer on a larger lawn, putting your grass out of use as it works – not the best news on a sunny day when you want to be outside.

Sensors 
Quite simply, the quality of the sensors will determine whether your robot mower will be able to dodge tricky corners and lawn edging, and whether it will eventually end up lost on your drive.

Wiring or not?
Some robot mowers require the perimeter of your lawn to be wired: this is useful for gardens with unusual layouts, but not so much for smaller, simpler gardens.

Slopes and lawn size
Before buying, measure the area of your lawn and any slopes. Robot lawn mowers are often accused of not being able to handle slopes, but ours can all cope with at least 15 per cent gradient – one can handle up to 50 per cent which is pretty steep. 

The lawn size is often indicated in the model number. Some models on our list come in bigger lawn sizes, but have similar functionality – albeit for a higher price. The lawn size is generally limited by the boundary set up, the distance the mower can travel to and from the dock and the battery life.

Do robot lawn mowers collect grass?

The answer to this is almost always, no. That is the case for those on our list. Instead of wasting weight and unit space on a grass box, these mowers disperse the clippings as they go. This is actually a handy feature of many mowers and allows the lawn to benefit from the fertilisation of its own clippings.

Do robot mowers get stolen?

As with anything in your garden, should an intruder get in, the mower is at risk of being stolen. However, there are a few safety enhancements on some of our mowers to prevent theft. Many have a pin meaning thieves would not be able to use the stolen mower, others register you as the user so nobody else can app control them, and some will tell you where they are should they get taken away. 

Also, a robot mower with a boundary wire is not much use by itself so it would take a desperate thief to take the wire and dock too. We recommend making sure your mower is included in your home and garden contents insurance to be covered.
