Bosch AdvancedRotak 650 Review- Electric Rotary Lawnmower.
The Bosch AdvancedRotak 650 has a powerful 1700W motor and has a 41cm width of cut using a hardened steel blade designed for medium to large sized lawns. The smooth sound profile of the Bosch ProSilence prevents your lawnmower from disturbing your neighbours by reducing its noise level by up to 75% to 89 dB.
The Bosch AdvancedRotak 650 is the smaller brother to the Bosch AdvancedRotak 750, what’s the difference between them? well not much really apart from the slightly larger deck size on the 750. The AdvancedRotak 750 has a 45cm deck and the AdvancedRotak 650 has a 41cm deck size. Apart from that the two mowers have exactly the same features, even the grass box is the same with a 50 litre capacity.
The Bosch brand is also very well known and they too have an excellent reputation for reliable affordable products. The Bosch AdvancedRotak 650 is a powerful machine that can handle larger lawns while still remaining agile and easy to move. The strong 1700 watt motor will tackle any lawn with ease and the 45 cm blade will make quick work of your lawn.
One of the main features of this Bosch AdvancedRotak 650 mower is what Bosch call ProSilence. The point is that they are very quiet mowers. You have a wide range of 7 cutting height options from 20 to 80 mm. Changing the height is quick and easy. The large 50-litre grass box means fewer trips to empty the grass making your work even faster and more efficient. It is collapsible for convenience and easy storage.
Another feature is the ErgoSlide System. This feature makes the lawn mower easier and more comfortable to move around. The ergonomic handles will also add to the ease of use.
The Bosch AdvancedRotak 650 model also has a grass combs for great edges and corners as well as LeafCollect to gather leaves as you work on the lawn.

Difference between the Bosch AdvancedRotak 650 and Bosch AdvancedRotak 750
I have been asked, what’s the difference between the AdvancedRotak 650 and the 750? Well it is very simple, nothing is different apart form the size of the deck/blade. The 650 has a 41 cm deck and the 750 has a deck size of 45 cm, that’s it! The motor is the same power at 1700w and even the grass box has the same capacity at 50 litres.
Which one is best for you depends on the size of your lawn, with the 650 designed for lawns a maximum size of 650 m² and the 750 a maximum of 750 m².
The Bosch AdvancedRotak 650 features a 1700 watt powerful motor designed to cut larger and more demanding lawns whilst still providing a professional cut. This is assisted by the large amount of cutting heights that I will come onto later in this review.
This is a decent sized motor and able to cut lawns that tend to be left longer between cuts that have grown thicker and longer. The AdvancedRotak 650 made light work of my lawn when it was tested on my lawn for the first cut in April this year.
The other great feature of this mower is the ProSilence that reduces the noise level of this motor by up to 75%. I was sceptical at first but was pleasantly surprised at the noise level of what is a very powerful motor.
The video below from Bosch shows the Prosilence in action. It shows the AdvancedRotak with Prosilence at different distances and compares it to a mower (Rotak 43) without Prosilence.
The lawnmower comes with a 10-meter power cable. If more range is required an extension cord will be needed. This length of power cable is relatively standard but could be longer for a mower designed for larger lawns.
The Bosch AdvancedRotak 650 has strong 41cm hardened and ground steel blade. While these will need to be sharpened occasionally, they will give a clean, neat cut and they are extremely durable. If you ever do need to need to replace them, parts are easily available and reasonably priced.
The 41cm size is ideal for the medium to large lawns as it gives a good combination of speed and efficiency while still being easy to maneuver.
The Bosch AdvancedRotak 650 is equipped with one blade that gives them two very effective benefits…
- Metal blades generally wear less quickly than plastic blades which results in you needing to replace the lawnmower blades more often than a lawnmower that uses a metal blade.
- Metal blades are generally sharper and provide a cleaner cut to the grass blade, resulting in a neater, tidier and superior finish to your lawn and garden. And as stated above, the metal blades can be sharpened when needed unlike plastic blades.
Both the 650 and 750 come with a LeafCollect Blade that not only cuts the grass perfectly but also collects leaves for easy disposal. This feature is really very impressive and does indeed “vacuum” the leaves as well as cutting the grass perfectly leaving no chopped up leaves to clean up after, well done Bosch for a feature that will actually make mowing your lawn that bit easier and quicker.
To see the LeafCollect Blade in action take a look at my video review above.
As well as being able to sharpen the blades, it is also possible to purchase a replacement blade for the Bosch AdvancedRotak 650 for around £30 for a genuine replacement. Replacing the blade is relatively easy for anyone with basic DIY skills and tools.
It is essential that your lawn mower is highly adjustable to accommodate different lawn types as well as to accommodate for the different seasons. The Bosch AdvancedRotak 650 gives you a choice of 7 settings ranging from 20mm to 80mm on the front and rear wheels. Wow! 7 height adjustments! this really is impressive as some mowers I have tested only have 3, so no matter what type of lawn you have or what your seasonal requirements are, this mower will be perfectly adjustable for your needs.
If you have left your lawn to grow for a while, don’t rush in and cut it on a very low setting. Rather start on a higher setting and progressively cut it lower. This will avoid leaving an untidy patchy appearance or even scalping parts of your lawn.
Is 7 separate cutting lengths better than the competition, well yes. Some mowers at this price point only have 3 height adjustments, however, most will have 5 so it’s really does beat the competition hands down.
What really struck me about this mower when I was preparing to mow my lawn is the integrated height adjustment. Some mowers I have reviewed are so difficult to adjust the height, this is normally when the height adjustment lever is located towards the front of the mower or where you have to turn the mower over and manually adjust the front wheels and rear wheels separately.
With the Bosch AdvancedRotak 650 you get an integrated height adjustment feature that is so good and makes adjusting the height a breeze. The handle is located centrally and there is a perfectly placed button that is pressed to either raise or lower the mower. Again see my video above to see just how good this feature is.
The 41 cm cutting diameter of theBosch AdvancedRotak 650 is ideal for medium to large gardens. The Ergonomic design and and smooth running wheels will allow you to zip around the garden in no time but still give the precision and ease of movement for curves and edges.
Remember, 41cm is one of the larger deck sizes and is designed for lawns up to 650m², bare in mind a tennis court is around 260m².
If you like the features that Bosch have packed into this mower but want a slightly larger deck size then you may want to consider the identical AdvancedRotak 750 with a larger deck of 45cm.
Grass box capacity
Having a large grass box is a bit of a double-edged sword. On the one hand, it means that all the trimmings are collected and you need to make a few trips to empty it out. A smaller grass box or no grass box will make the lawnmower much lighter and easier to navigate.
Bosch have opted for a large 50 litre grass box on both the AdvancedRotak 750 and the AdvancedRotak 650 and makes sense as this mower is designed for larger lawns. The mower does a fantastic job of compacting the cuttings into this very large grass box meaning less trips to the compost for emptying. The 650 does naturally become heaver as the grass box fills but I never had any issues manoeuvring the mower around the lawn. Having said that I don’t really have any steep inclines in my garden, but I guess you could always empty the grass box before it is completely full or starting to become heavy.
The Grass box does come with a handy gauge indicating when the grass box is getting full, again a nice touch as not all mowers have this.
The grass box on both the 750 and 650 have a solid top and bottom and a woven material side. This allows the grass collection box to be folded nicely flat to reduce storage space. There are a couple of small negatives with this type of grass collection box:-
- The material is more prone to damage from tearing when in use, however, the material is good quality and if looked after should not be an issue.
- Because the grass collection box folds flat there are two fold-able arms near the box opening, when emptying the cuttings these slightly obstructs and restricts the flow of the cuttings when emptying. Also, because the Bosch 650 does such a good job of compacting the cuttings a good shake of the collection box is needed to eject all the cuttings.
These are very minor issues, I just thought you should be aware of them anyway.
Another thing Bosch products are known for is a great safety record. Obviously, if not used correctly, any lawnmower can be dangerous but Bosch has done everything they can to make the AdvancedRotak 650 as safe as possible without reducing its effectiveness.
The lawnmower comes with a detailed and clear safety guide and provided you follow these instructions you will not have any problems.
With the ProSilence Bosch have also kept vibrations and noise at extremely good levels for a mower of this power.
It conforms to all the main local and international quality and safety standards.
Another safety feature they have built in is double insulation to prevent any risk of electrical shock under normal conditions and use. It also has a protector to prevent the motor from overheating. When it reaches a certain temperature, the motor will shut off. Only once it has cooled down to acceptable levels can it be used again.
As with all corded lawnmowers, there is a safety button that needs to be held in in order for the starter grip to be activated. There is no additional removable safety key with the AdvancedRotak 650.
Good news! the Bosch AdvancedRotak 650 does have a rear roller for a stripey lawn.
The Bosch AdvancedRotak 650 does not have the ability to mulch the lawn out of the box, but an optional mulching attachment (Multimulch) can be purchased separately to enable it to do so.

Ten metres for a mower designed for larger lawns is not long enough. I know this is not such a big deal and can be easily rectified by an extension cable, but it’s worth mentioning anyway.
The Bosch AdvancedRotak 650 is a great all round mower that is designed for the maintenance of medium-to-large sized lawns.
The build quality is what you would expect from Bosch, a quality and solid feel to all parts of this mower, even the wheels have rubber tyres. This is a large mower with a powerful 1700w motor designed to tackle larger lawns and lawns that are more challenging, such as longer thicker grass.
What I like about this mower is the seven different cutting heights and the easy way you adjust the height from the central handle. This really does make a difference as many competitors have a single lever mounted at the front of the mower which you have to fight with to adjust the height. The other nice touch is the huge 50 Litre grass box that folds flat and has a “grass box full” display, well done Bosch.
Yes, it’s not the cheapest mower, but you do get what you pay for. Remember you get the Ergonomic and ErgoSlide handles that really do help to make the whole mowing experience that much easier as you can adjust the mower to suite the most comfortable posture while mowing your lawn. There are four power buttons, two on the upper grips and two on the lower making it easy to turn corners single handed whilst keeping the power going. This mower is so quiet for a mower of this size and power as the ProSilence reduces sounds by up to 75% to a very reasonable 75 dB.
And don’t forget the LeafCollect blades and the small footprint when this mower is folded away for storage.
All in all this Bosch AdvancedRotak 7650 is a fantastic mower full of features that can be used to help make mowing your lawn that bit easier and enjoyable.
