What are you buying?

The Bosch Rotak Electric Rotary Lawnmower is among the most powerful and convenient machines you will ever find. Thanks to an integrated 1700 W power drive motor, this powerhouse guarantees all the torque you need to deal with even the wildest lawns.

The Rotak promises outstanding cutting performance with credit to Bosch hardened steel blades. Combine that with exceptionally high torque and you have a mower with the ability to make short work of 30 cm long grass.

The manufacturer understands that mowing lawns is not just about butchering several thousand blades of glass. It requires extreme skill and precision to get that perfect cut on your lawn.

Fortunately for the less gifted workers, the Electric Bosch Rotak Ergoflex Rotary Lawnmower incorporates inset heels at the front and extended grass combs with the ability to cut grass growing extremely close to the edge of your lawn.

This way, no grass is left untouched, even when mowing close to flower beds, paths, and even walls. As a bonus, the integrated roller finishes off your lawn with a nice striped effect for great aesthetics.

However, the greatest feature in the Bosch Rotak Electric Ergoflex Lawnmower just might be the Ergoflex handles that make mowing lawns as big as 500 square metres a breeze.

Thanks to this ingenious design, not only do users get effortless control, but they also work with an improved posture, and significantly less muscle strain as opposed to traditional mowers.

Think you have a wild and messy lawn? Not to worry; the larger 50l grass collection box is more than adequate to give you more time on the lawn and less time emptying.

Key features summary

  • Power: 1,700 wats
  • Blade length: 40 cm
  • Cutting heights: 2 – 7 cm
  • Grassbox capacity: 50l
  • Product weight: 16kg
  • Style: Stand alone

How easy is it to use?

As you would expect, the Bosch 40 Rotak Electric Rotary Lawnmower offers superior features that are incredibly easy to use. Cleaning the cut grass is actually the most arduous part of the job and gives people unnecessary headaches.

Thanks to some creative Bosch engineering, this particular model incorporates a Leaf collection function that sweeps up 99 percent of the waste and debris. It is this innovative airflow tech that keeps your lawn looking spic and span.

Another strong point in the Bosch Electric Lawnmower that makes operation almost effortless is the handy, Ergoflex handles. Unlike traditional lawn mowers that require all your strength to mow along, all you have to do with this particular unit is apply a little bit of pressure, and the machine will do the rest.

Even with an overly large space to cover, the 50-litre grass box means fewer trips to the empty bin. The carrying handle is also convenient and makes it super easy to transport, especially since the Bosch Rotak Rotary Lawnmower is quite light.


What accessories are included?

Upon making the purchase, you should find the following items in the box:

  • 1 Bosch 40 Rotak Ergoflex Lawnmower
  • Instruction manual

Like most customers, it’s always wise to include additional items when buying the lawnmower. I ordered for the Bosch Rotak Multi-Mulch lawnmowers to complement my purchase.


  • Fast and easy single button setup.
  • Ergoflex handles for seamless control and improved posture.
  • Powerful 1700 W electric motor.


  • Some customers claim the grass box is a bit hard to assemble since it comes in three separate features.

Anything else you should know?

While the purchase is incredibly exciting and feature-packed, it may come as a shocker to many that the blades are not included. You will definitely have to buy your own set of blades and then install them later on. But once you get those puppies on, it’s precise, non-stop mowing.


From rudimentary slashers to the ultimate form of lawn maintenance tool, mowers have really come from far. If you prefer extremely high accuracy, speed, and comfort while going about your yard work, then the Bosch 40 Rotak Electric Rotary Lawnmower is precisely what you need.

With an extensive array of features and optimum levels of user-friendliness, every homeowner should find this model more than suitable for the job. If you want to know how it compares against other products, check my Best Lawn Mower Buying Guide.
