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.

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.

An amazing cordless mower


This is an amazing cordless mower. Lightweight, functional and easy to handle. The battery lasts. I have roughly 200 sqm of lawn to mow and it eats it all up with power to spare. Would happily recommend the product to anyone wanting a quiet (in comparison), easy to use mower.

Very good quality, but the batteries will inevitably die


I purchased this mower four years ago, with two batteries, and use it bi-weekly 3 seasons a year. My lawn is about 1/3 of a 600m^2 block, and I now go through about 1.5 batteries a session. The mower has never let me down, but battery capacity is markedly lower than when new. Batteries are expensive, but if you are willing to accept this cost, it's a powerful, quiet, and very light lawn mower! It is also surprisingly robust given it is constructed almost entirely of plastic.

Great mower with long battery life


I am a shortish 50 somethingish female with ms, so I was looking for a mower that did not leave me in pain. This is it! We have an average lawn size ( maybe 1/3 of a 870 sq block) and I can mow on one charge. Very impressed with the cut of the grass also. I have the height set on 3 to give the grass the ability to stay alive during Sydney summer. I like mowing..I am outside doing housework for a change..lol. I have only used it twice so far.

Mower fantastic - battery + charger ???


Mower fantastic - but when the battery charger blew its fuse it became too difficult to know what was wrong - the battery, the charger or something caused by the mower. Replacing the charger and battery is very expensive ... and if its a problem caused by the mower it could be a waste of time and money.

Expensive but good

I bought a Bosch Rotak 32L1S this year and I am very pleased with it, but I would like to know why it seems to cut out momentarily every now and again?

Hi Vivienne,

Would you mind sending me the 10-digit part number on the back of your tool or from the box? We don’t sell any Rotak model by that name here in Australia.

If the motor sometimes stops immediately, possible explanations are that the battery is not charged, the isolator key is not inserted correctly/fully, the battery is not inserted correctly, or the battery is too hot/cold. This is all outlined in the manual that came with your tool.

Otherwise, if the tool seems to function intermittently, a possible cause it that the internal wiring of the machine has been damaged, or that the motor protector has activated. If it’s the latter you should allow the motor to cool and increase the height of cut.

It’s hard to know what the exact issue is without being able to assess the tool ourselves. If you purchased your tool in Australia and you’ve tried all the above troubleshooting (as per the manual), you might consider taking it back to the store you purchased it from or to an Authorised Service Dealer for assessment.

To locate an Authorised Service Dealer, please call 1300 307 044 or visit the link below with a list of our Authorised Service Dealers in Australia:

Let me know how you go or if you have any other questions.

Cheers, Hayley

Hello Hayley, Thanks for your response. I bought it in Belgium, so a bit far to travel to fix the problem in Australia!! However I found the number on the machine - TYP 3600H85D04.

Hi Vivienne,

Ah, that explains it. Who knows, maybe you can turn it into a holiday as well ;)

The best thing to do would be to check the manual as its got a whole list of troubleshooting options. Otherwise, you can take it back to the place of purchase (in Belgium!) or contact the local customer service team and they should be able to help you out.

Let me know how you go. If you're really having trouble I can see if our team in AU can get in touch with the team in your country to help resolve this issue.

Cheers, Hayley.
