What is the The Husqvarna Automower 315. The Husqvarna Automower 315 is a robot mower designed for medium to large lawns of up to 5,000m² in size. It can handles slopes up to 45%, has built in GPS and mobile phone connectivity.

The Husqvarna 450X Automower really is in a league of its own.

With a max lawn size of 5000m², the 450X doesn’t have much in the way of competition, apart from a couple of other models.

The Honda Miimo 510 and the Ambrogio L300 comes closest in terms of lawn coverage so I think they make the best comparison.

To get an inside to the 450Xs features, functions and capabilities, and how it fairs against these competitors stay around because that’s exactly what I’ll be doing in the review.

Main Features:

  • Rating: 9/10
  • Can covers areas reaching 5,000m² in size
  • Spot Cutting function
  • Built-in GPS system
  • Mobile phone connection

To get you started and familiar with what the Husqvarna 450X has to offer, watch the video below. We will go into these features in more detail later on.


The 450X  is the most premium model that Husqvarna have on offer.

It covers areas reaching 5,000 m² in size, so is only suitable to those with extremely large gardens.

It can produce an incredible mowing time of 260 minutes with only a 75 minute charge, a truly astounding feat that no one else on the market can compete with.

Power System

As mentioned before, the 450X can cover gardens reaching 5000 m² in size. For those with lawns this size, it would normally take you about 2 – 3 hours to mow the lawn yourself and you would probably only do this once a week.

I have no doubts that your garden will look great immediately afterwards but would about after 3 – 4 days?

It probably begins to look a rugged and maybe the grass starts to grow a little uneven. You may even begin to see patches of dead grass appear.

Well that’s why the 450X is so helpful.

It will cover this area with no problems and can do it as many times as you want – even every day is you so pleased (which is actually recommended!).

Taking a huge weight off your shoulders and gives you a whole load of time to do whatever you want. All is required of you is to check up on the mowers work after each cut and make adjustments accordingly.

Now I don’t mean big, drastic changes but ones such as shortening the cutting height as the weeks go on – which you can do with the touch of a button!

Cutting Blades

The 450X is equipped with 3 razor sharp, carbon steel, cutting blades attached to a rotating disk in the centre of its base.

As they are not fixed in one place, the 450X’s blades just fly out due to centrifugal force. Because of this they are only powerful enough to cut through the grass and nothing else.

So when a small object (like stones, toys or twigs) crawls under the bot, the will not be damaged, and neither will the blades.

This solves a big problem that affects most models in the market and makes the point clear that you don’t need a large blade to be an effective mower. A very simple system is all that is needed.

This means you won’t have to clear the lawn before every mow like you would with most mowers.

But when the 450X does come into contact with any object, its sensors will automatically switch of its rotating disk and stop it in motion, preventing any damage caused to the blades.


The 450X cuts the grass into tiny pieces so the clippings can drop all the way down to the soil. As they decompose, they pass on nutrients to the soil to promote much healthier grass growth.

This makes for a much healthier, thicker and better looking lawn.

Mowing Features

The 450X is capable of mowing on areas where the slope reaches 24° (higher than the 315 by 2°) which is a little higher than most competitors can reach (only by 2°).

But I must say, the Husqvarna models handle these so much better than other models.

Most (not all) would either get stuck and turn off or begin to trundle down the hill again. Whereas as the Husqvarna models will glide up them with ease.

So to those with a slopped garden, no mower will be able to deal with your lawn better than these models.

Husqvarna 450XSpot Cutting

This feature is to ensure proper mowing over longer areas of grass.

Just place the mower in an area of long grass and select the “Spot Cutting” mode. It will then cover the chosen area in tight spirals and once finished will resume mowing just as normal.

This is particularly useful for areas under garden furniture – once the furniture is removed of course.

Narrow Passages

So that it can calculate the best way through the narrowest of gaps, the 450X has special built-in sensors which detect narrow passages.

Once the data is recorded the 450X will vary its route through those passages to avoid unpleasant tracks. This reduces the possibility of the mower getting into any sticky situations.

The unit has an easy to use settings panel which enables you to personalise its settings to your garden. For example, you can use it to choose which days and times you want the 450X to operate.

So that it adapts to the time of year, you can change its cutting height.  This adjustment can be made from anywhere between 20mm and 60mm.  Simply decide which length you want and then turn one large knob on top of the unit.

But make sure you don’t set this to the shortest length straight away.

By doing this you won’t make use of the ‘mulching function‘.

This is when the clippings are cut so small that they can seep in-between the grass and own to the soil. Once here they pass on nutrients onto the soils to produce a much natural and healthy lawn.

By gradually bringing down the cutting height each week, you will be able to take full advantage of this function.

Husqvarna App

So this feature is not so special but it definitely help remove you from the whole lawn mowing experience – which is main point of a robot mower!

First you’ll need to get the Husqvarna App sim card can plug it into your automower and then download the Husqvarna App to your phone. You can either do this through the app store for iPhones or through the Google Play store for android users.

Once you have downloaded it you will have to create a new account and just follow the steps. From here you can give the mower a name and then connect it to your phone.

For a visual on what to do, watch the video below:

Once you have the app up and running, you can begin making changes to 450X mowing system.

You can do stuff like alter its mowing schedule, cutting height and send it out or bring it back from a mow.

It also shows & notifies you of any problems caused to the mower at any point and shows you a map of the garden. From this you can see the progress it has made throughout the day using a heat map or a line trail.

Now I’m not going to say this is any better than the others, because I think it’s on par with the likes of Bosch and Robomow, but take nothing away from it.

This is a great feature and will prove very useful during winter when the last thing you want to do is go out and fiddle around with a freezing cold mower.

Weather Timer

A unique feature of the 450X is its lawn height sensors.

These enable this model to adapt its schedule according to the lawn’s changing growth throughout the year.  So in times of strong grass growth the 450X will maximise mowing for a more effective cut.

In periods of sunny or dry weather the 450X will spend less time mowing.

Preserving your grass and reducing wear on your mower.


As the 450X has an electric motor it doesn’t produce harmful emissions.

It also operates at a very quiet 58 dB, so no noise pollution either. So you can program it to work during the night, it won’t wake you up and will certainly keep the neighbours happy.

Due to efficient energy management and unique cutting system, the 450X Consumes low quantities of energy therefore operating at a fraction of the cost of conventional lawnmowers.

Weather Proof Design

The 450X is designed to work your lawn constantly throughout the year, functioning fully and unattended regardless of weather conditions.

This is because it has been designed to withstand the harsh Nordic climate – so it’s pretty tough!

And if you have a particularly tough lawn for the mower to travel over, you can order special coarse-treaded wheels. These promotes much better grip and allow the mower to work in slippery, wet conditions.

Rain Sensor

Now even though it can mow in the rain, doesn’t mean it has to. In most cases this will cause damages.

So the 450X has been fitted with a rain sensor to detect when the rainfall gets that little bit too heavy. It will then lead itself to its docking station to charge and then, when the rain stops, it’ll lead itself back out to continue mowing.

Limiting any damage to your lawn.

The only real problem that the mower can’t deal with is frost. When it gets really cold, the bottom of the mower may freeze over, stopping it in its tracks.

Safety Features

To ensure complete safety to you, your children and pets the 450X has several built-in safety features.

Quick Stop Blade Function

If at any point during mowing you attempt to pick up the 450X, or if for any reason it tips over, the cutting disk will automatically stop rotating preventing any injuries to the hand.

Not only that but as an extra precaution, the 450X has adequate space between its border and blades.

Leaving just enough room for your fingers.

Remote Object Detection

As said earlier, 450X has ‘remote object detection’ as well as bump sensors.

So when the unit comes into near contact with an obstacle during its route, it will stop, redirect itself and continue mowing in a different direction.

It will also avoid this area for future mowing.

PIN & Alarm System

A PIN and alarm security system has been built-in to prevent operation by anyone unfamiliar with the controls.

This should scare off the odd burglar who tries to chance his luck and will stop the kids trying to use it without your supervision. A very common but equally important and useful feature.

You will also get notification of unusual activity on your phone provided you have your phone.

Object Sensors

It has built-in object sensors which make use of Ultrasonic technology. This helps the mower detect obstacles more accurately, lower its speed quicker and avoid hard collisions.

If the unit does come into near contact with an obstacle during its route it will stop, redirect itself and continue mowing in a different direction.


There is just one downside to this mower, and it affects all the robomowers in the market. As of yet no one has been able to fix it and Husqvarna are just the same.

  1. Like all mowers, this model can’t reach any grass outside of its loop wire so you will have to do some trimming every few days.

And that’s it. Only one flaw in an otherwise perfect mower.

So you can see why I rate these models so highly.

Husqvarna 450XConclusion

With so many great features and only the single downside, I definitely think that the 450X has outshone the Miimo 510 and the Ambrogio L300.

Its mowing system is second to none, it makes use of some of the finest technology in the market, it’s super efficient and has all the bells and whistles you could ever need.

Considering how easy this system is to use, the results it produces and how much energy you would save, I honestly believe that this model is the best in the market for its lawn size.
