Are Robot Lawn Mowers Worth It? The Real Cost, Time & Savings Explained

18 June 2026

Robot lawn mowers have exploded in popularity across the UK over the last few years.

Once considered a luxury product, modern robotic mowers are now maintaining everything from small suburban gardens to large country estates.

But one question still comes up more than any other:

Are robot lawn mowers actually worth the money?

With quality robotic mowers ranging from around £800 to over £5,000, it’s understandable that homeowners want to know whether the investment makes sense.

At Taylormade Garden Machinery, we install and support robot mowers from leading brands including Kress, STIHL iMOW and STIGA. In this guide, we’ll look at the real costs, benefits and long-term value of robotic mowing.

The Average UK Homeowner Spends More Time Mowing Than They Think

Most people underestimate how much time they spend cutting grass.

Let’s look at a typical example.

• Average mowing session: 45 minutes
• Mowing season: March to October
• Average cuts per year: 30

That works out at:

22.5 hours every year spent mowing.

Over 10 years that’s:

225 hours.

That’s almost six full working weeks spent behind a lawn mower.

A robot mower gives that time back.

While you’re at work, with family or enjoying your weekend, the mower quietly maintains the lawn automatically.

Better Lawn Quality Without Extra Effort

One of the biggest surprises for robot mower owners is the improvement in lawn quality.

Traditional mowing removes large amounts of grass at once.

Robot mowers cut tiny amounts regularly.

This creates:

• Thicker grass
• Better colour
• Improved moisture retention
• Natural fertilisation through mulching
• Reduced weed growth

The result is often a lawn that looks healthier than one maintained using traditional weekly mowing.

What Does It Actually Cost to Run a Robot Mower?

One of the biggest misconceptions is that robot mowers are expensive to run.

In reality, most robotic mowers use very little electricity.

Typical annual costs include:

• Electricity: £10–£30
• Replacement blades: £20–£60
• Optional annual service

Compared with petrol mower fuel, servicing and maintenance costs, robotic mowing can often be cheaper long-term.

When a Robot Mower Makes Financial Sense

A robot mower makes the most sense if:

• You regularly mow your lawn
• You have a medium or large garden
• You value your free time
• You want a consistently healthy lawn
• You dislike mowing

For many homeowners, the convenience alone justifies the investment.
