Husqvarna Automower 450X Robotic Lawn Mower Review

The robotic revolution is here and has evolved from the indoors of home vacuum cleaners to a new line of durable, and thoughtfully designed robotic mowers like the Husqvarna 450X Automower. As a well-established name in the lawn care industry, Husqvarna has a reputation for quality engineering and ease of use throughout their product line.

The 450X Automower represents the peak of the Husqvarna X-Line Series. It has an 18 Volt rechargeable lithium-ion battery. At a full charge it’s capable of up to 270 minutes of run time, or up to 1.25 acres and has an average charge time of around 60-minutes.

The X-Line series also gives the Husqvarna 450X Automower access to their Smart Technology Automower interface. It’s an intuitive app that can be linked to your smartphone. It’s also compatibles with both Amazon Alexa as well as Google Home. It also gives it GPS navigation as well as theft tracking features.

The cutting deck can be set anywhere between .8-inches up to 2.4-inches depending on the weather and the current conditions of your turf. Underneath you will find three small blades, which produce a neatly trimmed 9.45-inch cutting path. Husqvarna even includes 9 replacement blades in the package purchase.

The body has a rubber front bumper, with painted wheel caps, and LED headlights, which let you see it better in low-light conditions. It can handle up to a 24-degree maximum incline for modestly hilly yards.

Key Features

  • 18 Volt Rechargeable Lithium-Ion Battery
  • Up To 270-Minutes Of Runtime
  • 60-Minute Average Recharge Time
  • Cutting Height From .8-Inches To 2.4-Inches
  • X-Line Intuitive Interface
  • Compatible With Amazon Alexa And Google Home
  • GPS Navigation And Theft Tracking Feature
  • 3 Blades With 9.45-Inch Cutting Path


The X-line interface with GPS navigation lets you determine the ideal cutting parameters for your lawn. The 18 Volt rechargeable lithium-ion battery has a runtime of up to 270-minutes on a single charge. It can also recharge in as little as 60-minutes. This gives it the impressive capability to mow up to 1.25 acres of lawn.

The Husqvarna 450X Automower’s motor and wheels are capable of climbing an incline of up to 25-degrees, which is enough to handle most modest hills.

It’s also worth noting that this mower only produces 59 dBa of noise. This is the equivalent of a running air conditioner 100 feet away or an average conversation in an office.

Ease of Use

The X-Line was designed to be easy to use, with an intuitive interface and a smartphone app. The fact that you can pair it with Amazon’s Alexa or Google Home lets you easily add it to your existing suite of smart home appliances.

The fact that it was designed to be weather-proof also spares you the fear of a surprise summer downpour damaging it if it happens to be on the far side of your lawn.

Cut Quality & Options

The Husqvarna 450X Automower can cut up to 1.25 acres or 270-minute runtime on a single charge. This is a pretty significant volume. As part of the X-Line the intuitive interface, smartphone app, and GPS navigation make it easier than ever to dial in the parameters that are best for your lawn.

The cutting height can be adjusted from .8-inches for times when the sun and rain make for vigorous growing conditions, to as high as 2.4 inches. When the grass is left this tall it helps shade your turf during prolonged dry periods. The 9.45-inch cutting path is a little narrow compared to larger walk-behind electric mowers, but it’s relatively efficient for a robotic lawnmower like this.

One minor, possible complaint with the Husqvarna 450X Automower is that it doesn’t have a rain detection feature built into the unit itself. This isn’t necessarily a safety issue, as this robotic lawnmower was designed and built with superior weather resistance. However, excessively wet grass doesn’t always cut the best.

A rogue summer rainstorm that sweeps in and out in a few minutes isn’t a big deal. Still, if you know that there’s heavy rain in the forecast you might want to use the smart technology app to suspend operation until things dry out a little more.

It doesn’t have a dedicated mulching feature, which is common with robotic lawnmowers. Ideally, you want to set it up to mow frequently. This will create small grass clippings that easily decompose to feed nitrogen and other nutrients back into the turf.


The Husqvarna 450X Automower is nearly effortless to maintain. The 18 Volt lithium-ion battery recharges in around 60-minutes.

The blades will need to be replaced one to two times per year. Husqvarna includes 9 replacement blades when you purchase the 450X Automower. They were designed to be easy for the average person to replace on their own without having to seek out professional assistance.

Safety Features

The Husqvarna 450X Automower has special sensors built-in that let it detect obstacles as well as a rubber front bumper. There are pegs, loop wire boundaries and guide wires to help define its limitations. The X-Line app also lets you employ GPS navigation for larger yards.

Special Features

The Smart Technology interface and smartphone app with Alexa and Google Home compatibility let you dial in the Husqvarna 450X Automower to the particular characteristics of your yard. The GPS navigation and theft tracking are also nice features.

The weather resistance engineering protects it from damage from summer rains.

Cost Effectiveness

Electric robotic lawnmowers like the Husqvarna 450X Automower are incredibly cost-effective. They use a minor amount of electricity from your home utilities to cut an enormous amount of grass, all with little-to-no effort from you.

The Smart Technology features built into this robotic mower let you adjust its performance to make sure it is mowing your lawn in the best possible pattern. The weather resistance and the two-year warranty that comes with the purchase also gives you the peace of mind of knowing that your investment has the durability to pay for itself.
