A very uesful and informative review.

Perfect, best thing I bought ever


I owned every type of lawnmowers before, but this Bosch battery powered is the best I ever had. Light, cuts beautifully, doesn’t make dust, picks up everything, and looks awesome cute . With a spare battery I’m always finish my average size lawn.

Good product for small size lawn!!


This Lawn mower is very handy for small size lawn. I bought it for my old man who lives in two bedroom apartment and has no grass at the front but small lawn at the back. He absolutely loves it.

Although he is in love with this but when i tried this on my average size backyard it was struggling to mow. So would only recommend this product to people who have small yards.

A full charge batter can last for about 15 to 20 mins.

Purchased in September 2015 at Bunnings Warehouse for $599.00.

Great little mower for small yard


I purchased this little mower for my front small yard. It does a great job, I mow regularly so am able to leave the catcher off. My only criticism is that the 2 mainonoff switch needs to be held in for the duration , which requires both hands to do so. This makes life difficult since one has to continually stop the mowing process in order to move the electric lead out of the way. A bit of a nuisance to say the least. You could get the job done in half the time with a more thoughtful design hre

This is perfect! Cannot live with it !


I'm very happy with this movers' cutting results. It is very easy to maneuver the mower. This brand mower is easy to operate and maintain. It is also not heavy to women so that I can operate with ease. It is also flexible to collect and clean. Overall, i'm satisfied with it.

Still working great after a year use


Great electric lawn mover.

- Battery still running good after an year use. I can use it for my whole big backyard, decent size front yard and nature strip.
- Powerful enough to cut through the grass
- Great customer support
- Light weight and easy to clean

- Wheel axle started rusting
- Pricey option compared to others

Excellent Quiet Light Mower!


This mower is very powerful and easy to use though it's only a battery operated one. I had to change from petrol to the battery operated one because it's easier to use for my dad. It's very light to maneuver. To start you just need to press a button. Very easy to clean and maintain too.

Good powered Electric mower


I bought this from bunnings along with trimmer that came in the box.
This is powered by wire, which trains most people off- but I don't like petrol mowers due heir maintenance requirements.
For this, you just plug in and go.
It is just about very simple learning curve of how not to mow over wire.
This unit is pretty powerful and does the job. I have about 300m2 lawn and face no problem even with knee length grass. Price was $200 combined mower plus trimmer.

Great Lawnmower but not AL 3640 CV Charger


I had exactly the same problem as the previous reviewer (Roger on Nov 23 2016) - the AL 3640 CV charger suddenly stop working after 4 years while the lawnmower is going just fine (the lawnmower is not that often used over the 4 years). Followed Roger's comments and located the original article (http://galooph.com/blog/2015/11/13/repairing-a-bosch-al-3640-cv-charger/), I have managed to replace the 1W 180k resistor and got the charger working again! $0.25 instead of $190 for new charger is something unbeatable. Agreeing with Roger that Bosch should have better solutions/warnings on this problem for their customers. Thank you Roger and gallooph for sharing your tips/solutions!!!

Great mower - shame about the charger


I've had this mower for quite a few years now and it works brilliantly all the time. I don't have much lawn to mow (and even less now that I built a new house) but the one thing I'm hearing a lot of is the under-engineered battery charger dying...and considering the faulty part bringing your mowing to a halt is a 25 cent 180k resistor I'm not impressed with Bosch's engineers on that count. However there is a well written article by a guy called galooph who explains really well how to fix it (though I think his wattages were wrong and I replaced the resistor with a 1W 180k-ohm resistor and all is good again. Maybe I should start a service for repairing chargers in Melbourne ;)

Served me well


I was happy for 4 years then all of a sudden battery would only last 5 minutes after charging so bought a new battery, not cheap nevertheless cheaper than a new mower, new battery appeared to change but zilch power, was told the charger had died rather than the battery.

Bosch Rotak LI Series



  • The latest push mower in the Bosch Rotak LI Series is the Rotak 32-12, a battery-powered mower with a 1200W Powerdrive motor and 13Nm of torque that’s suited for small to medium-sized lawns.
  • The height of cut for this mower is between 20 to 60mm, so you can mow to a length that suits you and your yard.
  • It has ErgoFlex handles to help reduce stress placed on your back and arms, so you can easily mow with a good posture. It’s also adjustable so you can customise the mower for it to be comfortable and suited to your body.
  • The mower can cut your lawn right up to the edge, so you don’t need to go in later with a different garden tool to clean up the sides.
  • Weighing only 6.8kg makes this mower easy to move and push around the lawn.

Points of praise:

  • Most reviewers found that the Bosch Rotak 32-12 was lightweight yet surprisingly robust and powerful.
  • They also found that the mower was easy to operate and push around their lawn.
  • According to reviewers, cleaning and maintaining the machine was simple (partly thanks to its battery operation).

A point of pain:

  • For some reviewers, the charger for the mower wasn’t as durable as expected, and needed repair or replacement after just a few years of use.
