By  Enda

Thanks for taking your time to read our review on the popular Bosch AHS 55-20 Li cordless hedge cutter with the model number of 0600849G70.
The blade length is 55 cm (20 mm tooth opening) and this trimmer also has the Bosch anti-blocking system that ensures you get good reach, and no risk of hedge getting lodged between the blades. That is very good for really neat and precise cutting.

This model is sold as a complete package, so you get a cordless hedge trimmer complete with an 18V battery and charger. It is an excellent deal and of course you can't really go too far wrong with a Bosch model tool of any kind. Bosch are extremely well known for their power garden tools.

Hedge Trimmer Main Review

We have completed a full review just below, and we have concentrated on the key features that you should consider before buying this model.

EAsy to use
value for money
battery life

Value for Money

This is sold with battery and charger, so as we mentioned earlier, so this is excellent value for money. With a lot of the other trimmers you have to buy a battery and charger seperately, so this is quite an advantage.

This complete trimmer package is on average £130. Also, going forward, if you like to own and use high quality tools like Bosch, then a whole range of cordless tools can be used with the same battery and charger.

At this price then, you have to think this is very reasonable.

Battery Life

You can use the Bosch 5Ah batteries and it has excellent life. It will last for around an 2.5 hours without needing a charge.

This of course will depend on the thickness of the hedge, but as a general guideline, you will get at least 2 hours of trimming with this battery. It will then take an hour to get it back to fully charged

Ease of Use

This hedge cutter is extremely light and provides cordless mobility with maximum power. The 550 mm blade length, 20 mm tooth opening and the electronic “Anti-Blocking System” ensures you’ve got the right garden tool to get the job done

We found that this hedge trimmer will easily cut until you get up to branches around 2cm in diameter. After that you will need to use a saw or lopper. The Spear and Jackson Telescopic Lopper is particularly good for that type of heavier branch work.

Important Basic Features

Most people just want a trimmer that will take care of their hedges. The beauty of a cordless hedge trimmer is that you can use it anywhere, and you never have to worry about accidentally cutting through another electric lead again. (If you have ever done that, you know what we mean!)

The Blade

The blade length on this is 55cm (just under 22") so quite a good width and big enough for most hedges. The blade is sharp and coated to stop it from sticking, and the blades are very easy to replace should you ever need to.

The Cutting Stroke Speed

At 1,500 strokes per minute, this is fast and will quickly trim hedges. This trimmer cuts on both sides which you will find extremely handy.

The Battery Life

We have already explained this above, but Bosch hedge trimmers have one of the longest battery life of any of the branded hedge trimmers.

What Features Make this a Better Choice?

There are lots of these cordless hedge trimmers on the UK market. So what makes this one different from the rest?

Great Build and Construction

When you think of top quality tools then Bosch will definitely be one of the makers that comes to mind. This hedge trimmer is superb quality in every way and all at a bargain price. The blade is a good length and it does have the Bosch anti-blocking system.

Compatible with other Bosch Power Tools

If you have a range of Bosch tools then you will know all about their batteries. This battery fits 100+ other Bosch  machines , from hedge trimmers and chainsaws to combi drills and jig saws, in fact any other 18V tool that Bosch make.

Our Verdict on the Bosch Hedge Trimmer

94% online buyer satisfaction based on 500+ online buyer reviews

It's very hard to look past this Bosch cordless hedge trimmer for value alone. Most buyers got this to replace an old petrol model and they were amazed at how well it worked. The battery is brilliant, it is a two handed operation that cuts on both sides and will go through branches up to 2cm.

I'm not sure what else you would be looking for in a hedge cutter. This is a great model and it's a very reasable price. It's extra good that you don't need to buy a battery and charger.

I can't recommend this model highly enough and if you are looking for a model that's very light and easy to use then this would be top of your list.

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.

They are a German brand and their garden products are very popular with many UK gardeners. They have 40 locations spread across the UK with over 5,000 employees. In the UK they generate annual revenues of around £3.5 Billion, with the UK being their second largest market.


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.
