Bosch Rotak 32 LI Cordless Lawn Mower UK Review 

 April 25, 2019

By  Enda

Thanks for taking the time to read our UK review of the Bosch Rotak 32 LI Ergoflex Cordless Lawn Mower. If you are considering making the switch to a cordless lawnmower, then this model could indeed be a good choice for you.

As yet in the British market, cordless lawnmowers are still an expensive purchase, but there is no doubt they will get cheaper in years to come. The average good quality cordless mower will cost anything between £180-600 depending on the brand and size of the mower.

The people who buy these cordless mowers are essentially looking to find a compromise. They are fed up with having to get an extension lead out, because the leads on most ordinary mowers are just too short.

They also want the portability of being able to take the mower with them and perhaps to cut grass at a neighbour's home, a relative's home or to a graveyard to tidy up a plot.

Now you can do all of that with a petrol mower that has a small engine. However those are noisy and they are not that good for the environment. Many of them are also hard to start, and they do need regular maintenance.

The cordless mower fits nicely into that gap in the UK market, and is becoming a more popular choice, despite the initial expense involved.

Now let's have a detailed look at this Bosch model, which we believe to be a very good choice for small to medium sized lawns. (Up to 150 square metres)

In most cases this Bosch Rotal 32 LI can get a lawn cut with a single battery charge, which will then last around 25-40 minutes.

The Rotak 32 LI cordless lawnmower is a compact mower that offers cable free unrestricted mowing. It has a lightweight design that makes maneuvering around obstacles a breeze.

This cordless mower provides a clean cut and has grass combs for cutting edge precision.

The Bosch Brand (Gardening)

Bosch are of course a very well known tool brand. Aside from their high quality tools, they also make a wide range of gardening tools. These range from lawnmowers, lawn rakers, verticutters, trimmers, hedge cutters, chainsaws, leaf blowers shredders and multi-tool systems.

Top 5 Features

Just below we explain what we believe to be the top 5 features about this Bosch cordless mower

Feature 1 - Cordless Freedom

This is the main reason that many home owners in the UK buy a cordless mower in the first place. With a mower like this you no are no longer restricted by where your power supply is located, or how far the head can run.

There is no need to run extension leads through the home, or indeed worry about cutting through electrical leads. As long as you have the battery charged you are good for about 25 minutes minimum, and up to 40 minutes in shorter grass.

Feature 2 - Using the Mower

Some mowers are heavy but this 32 LI weighs only 10.2 Kg. That is very light for a mower, and when combined with integrated folding handles makes storing this mower very easy.

Bosch have also included electronics within this mower (A Syneon chip) that controls the energy from the battery to the blade, and that means more efficient use of your battery.

This mower is very quiet when compared to other types of mowers. 

You can adjust the grass cutting height from 30-60 mm by using a small lever.

The blade is sharp and works well and it has a 320 mm cutting width.

Feature 3 - Small to Medium Sized Gardens

Bosch designed this mower to be suitable  for small to medium sized gardens and is suitable for all grass types. (Up to 150 square metres)

This mower can cut grass on slopes, as well as around trees, shrubs and flowerbeds.

Its integrated grass combs allow the Rotak 32 LI to effortlessly mow along fences and driveways. This mower is easy to push on all types of terrain.

Feature 4 - Battery Charging

The battery life on this one is very good. During the charging process the 3 green LED lights light up one after the other. The battery is fully charged when all 3 lights light up continuously.

You also get a 2 second signal beep at the end of the charge.

The battery has a charge control indicator which indicates its charge condition.

It takes 70 minutes for a full charge. 

Feature 5 - Warranty & After Service

All Bosch lawnmowers and gardening tools come with a 2-year warranty. This can be extended to 3 years if you register your mower with them online.

With anything Bosch branded, there is a good after service. The most likely part that will need replaced on this Ergoflex model will be the blade, and you can be sure that they will have that blade available for many years.

Likewise if the batteries ever do need replaced, then they will stock those as well.

Our Verdict on the Bosch Rotak 32 LI Ergoflex Cordless Lawn Mower

If you are in the market for a good quality cordless mower that has been tried and tested, then this Bosch model is a good choice.

The buyer rating on this model is high, and there are plenty of online buyers. If you have a small or medium sized garden then this is an ideal choice.

Don't buy this one though if you have a larger garden. For that you will need a mower such as the Bosch 370, which you can read about here.

This 32 LI mower sells really well in the UK, and overall buyers seem to really like it. It is a good choice for a small to medium sized garden.

Buyers do like the Bosch brand and they do always have parts available, a solid warranty and good customer service.


I am someone who enjoys a little gardening. Now I am not someone who spend hours in the garden, but I do like both my front and back gardens to look really nice. Well kept lawns, neatly trimmed hedges, and borders filled with plants, make a huge difference, to how your property looks.
