Bosch Rotak LI Series

who called the bosh mower a heap of crap who called this heap of crap a mower ????? – 0 stars I am so p*ssed off with bosch and their U beaut battery mower. (1) Bought at ole mate Bunnings (not noted for Customer service and helpfulness) (2)Hardly had this U Beaut home when it would not start. (3) Back to ole mate Bunnings who don't want to know; oh we don't sell these mowers any more WOUNDER WHY?????? (4) Pulled the mower apart… Read more

and found the safety link faulty; bridged this out and mower ran alight for a while. (5) The height adjustment for the wheels is a joke; crap plastic parts that break; height adjustment handle broke off; crap plastic bits again. (6) Any dust causes dry joints in the connectors; don't know how many times I have had to pull this toy apart to it keep it going and had to split the electric motor to clean the contacts to get the thing to run!! (7) Any negative review of the Bosch battery mower brings out the waffle artists at Bosch."we are so sorry to hear of your problems with our U BEAUT mower; reach out to us at xxxxx" from the Bosch nonsense artists. (8) These Bosch nonsense artists claim thy are so sorry - sorry enough to give the punter a full refund for his hard earned ???? - obviously not on this sorry heap of crap Bosch claim is a mower. (9) Bosch has a hide foisting this heap of crap on its long suffering ex Customers at the prices they are charging.

This is far from perfect - I can live without it – Wife bought this mower at our old mate Bunnings. The mower used to not start so off to old mates store. WE don't sell these any more!! Thanks for nothing. The safety key was the problem and failed numerous times, Cut out the safety key and mower performed better for a while. These mowers are an over priced toy!! I have had to pull this mower apart… Read more

more times than i have had hot dinners to keep it running. The height adjustment for the wheels is a joke; crap plastic parts that break; height adjustment handle broke off; crap plastic bits again. Any dust causes dry joints in the connectors; don't know haw many times I have had to pull this toy apart to it keep it going. This mower is more trouble than its worth!! I will not be buying another Bosch U beaut, that is for sure!! Save yourself the grief; this product does not CUT IT. (pun intended) OH yes, and over priced to the crap house!!

Light to manoeuvre battery good but $$$ – after 10yrs service from a Vista 2stk corrosion and repairs to the body/throttle setup/handle it was time to look for a replacement. $700 when it was newly released and perfect for my folks due to relatively small lawn area but it's an expensive mower. Bought extended warranty through Bunnings and needed it once when the charger failed.… Read more

Acceptable turn around on repairs and found the charger to be at fault. No issue with Bunnings in my area, it was pain free. No doubt probably because it was the charger a fault and it seems common for such an early model.

However it's now needing bearings as it's loud and creates resistance on the motor, and the safety lever mechanism (plastic) has broken. Just got word back from the repairer it's gonna cost over $400 in total to repair inc. the bearings. We're now on the look out for another mower.

I don't believe we've got our monies worth out of no petrol use but it has served well with being highly manoeuvrable due to it's light weight. Folks just hired a petrol job to make do and they couldn't believe how heavy it was after not using one.

Served well on buffalo. It's a bit harsh to pit value against ease of use but would buy again.

Long live the Rotak 37LI. Roughly 5yrs of use in the Tropics FNQ.

After 5 Years, Still A Charm – I have two of these, one a 37li the other a 43li. The 43li was imported as soon as released from the UK, might even be 6 years old. I bought two batteries to start and they are both working. The batteries are looked after, as in stored at about half charge, not sitting on the charger all the time in the heat, etc. We now live on acreage… Read more

(last 2 years) and use this mower for about 150m2 that can't be accessed with the ride on mower.

I've read that they don't like long wet grass. This is true and includes my $6000 mower, it doesn't like wet tall grass either.

So, keep it regularly mowed and mow late in the day when the grass is dry and the sun doesn't burn your grass after its cut.

The upsides.

- No messing around with fuel and reliable.

- Simple and quiet.

- Lasted better than expected.

- Works very well with a nice cut.

Downsides.

- The charger just stopped one day, in about the 4th year and new ones are expensive. (maybe $120?)

- I bought a secondhand mower and battery from a guy for less and they have both still work great.

I can't ask for more really. Really worth having 2 batteries. The Bosch whipper snipper (36v) uses the same battery and comes with a charger. Much better value than buying a new charger if you ever need one. Very good whipper snipper too.

Expensive but good – Prior to purchasing this mower I was undecided between this and the larger Rotak 43. My existing mower is a 40 cut. My rear lawn is approximately 10 x 10 and my front 10 x 5 metres. That is a total of 150m2 and the mower is good for 300 according to Bosch. That is short grass in dry conditions with the cut set to medium. Additional batteries are… Read more

available but they cost around £90.00.

The battery took 30 minutes to be fully charged whilst I assembled the mower. Assembly of the mower was quite easy to do. Most difficult part was tightening the two screws that secured the handle into the mower. No problems with the grass box. Instructions were quite small to read though.

I found the default grass height setting of 3 hopeless and had to set the mower to 1. A plastic insert requires removal for you to achieve this. Possibly you are discouraged from using the lower cut to save battery power. In use I found the mower very easy to manoeuvre and obviously so much easier without a cord. The lawn looked very good after cutting.

The battery had faired well and the indicator showed one of the three green LEDs lit indicating a 1/3 of the power remaining. The grass was dry and about 25mm in height. It seem like there should be sufficient spare battery capacity to deal with longer or wetter grass. The grass box was emptied three times. With it being the smaller of the two mowers there was no problem in emptying the grass into the green waste bags.

In summary for my garden size the Bosch Rotak 37 has been a good choice. It's light and easy to manoeuvre and store. Cutting the lawn was almost a pleasure

8 years and still going strong – I have had this lawnmower for the last 8 years and the battery power is still good. The blade has gone blunt and that reduced its efficiency. Overall great product and now thinking to upgrade it to a newer model. Show details

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. Show details ·  2

Motor spins a few times then stops,give it a month maybe two and it starts again sales and services – Motor keeps stopping then spins a couple of times then stops again.give it a month or two then it works fine again.dont know if Bosch are aware or not but the grass keeps growing!sales and service pathetic no wonder they lost the war with machines like this,tanks would only fire on certain days.  Show details

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… Read more

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

Very happy – Very happy. Use it to do around the pool and path edges. But inlove it so much i use it for the entire yard over winter as it is so ligt and easy to use. Struggles a bit in long thick sir walter but still cuts fine. Highly recommend. Great  Show details

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.  Show details

Still working great after a year use – Great electric lawn mover. Pros: - 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 Cons: - Wheel axle started rusting - Pricey option compared to others  Show details

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.  Show details

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… Read more

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… Read more

(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… Read more

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 ;)

Great mower! – This is a great mower. I upgraded to this from a electric cord one on a different brand. The frame is sturdy and solid. I love the fact it's battery operated so no need to drag cords around or remember to have petrol on hand to start the motor. It's easy to operate, and cuts well. Just don't cut it when the grass is wet otherwise the mower… Read more

cuts out and you need to give it a few secs to restart.

Only gripe would be the battery doesn't last long enough. I use it to mow my 700m2 block, but if the grass goes longer than 3 weeks without mowing it's too long for the mower to cut it all and battery runs out about 3/4 of the way through. sometimes 1/2 way through mowing if it's the grass goes crazier than usual after 3 weeks. Otherwise, I'd happy recommend this to anyone with a block of less than 700m2 unless you purchase a second battery to continue your mowing.

Grass jams the edge of blade – I really like Bosch cordless power tools but unfortunately this time, I am a bit disappointed. It's not a problem with Bosch, rather the overall electric mower is still rather under powered. I had high hopes for the mower but it regularly jams due to grass being stuck against the blade and the corner where it egresses into the collector. This mean… Read more

constantly turning it over, to clear it by hand - or cutting in 2 passes, gradually. The blade is also extremely light weight and easily dents.

The concept is great however, very light and easy to maneauvor around but I think it just isn't mature enough to handle grass we have here. A more powerful motor and battery combination, might resolve the problem but I think this is suitable for most suburban flat light lawns however stuff we have around the sub-tropics and farms, needs a lot more grunt.

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.  Show details

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,… Read more

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.

Good Mower but Battery Questionable – I bought our mower 9 months ago. I did my homework and read the customer reviews which appeared 50/50 in their opinions (like/dislike), the main complaint seemed to be the battery/charger. My dad always used Bosch power tools as they were a good, quality brand so I went ahead and bought one. The mower worked great - cut the grass as good as any… Read more

petrol mower, was quiet and lightweight.Then I noticed the battery would go flat faster and faster until it didn't charge at all. I've since had it repaired under warranty (Bosch replaced the battery and charger). It's charging better than ever before so I suspect the battery or charger was faulty from day one. Overall a good product if your charger works.

Perfect within its design parameters – Bought this today on special for a bargain $400 from bunnies. I have two small lawns totalling around 70m2. They are terraced and Kikuyu making them a tough and hardy challenge. Having struggled with a 2 stroke Victa for entirely too long I decided to invest in a 36v mower. Initially I borrowed a mates Ryobi to make sure they could get the… Read more

job done.

I was genuinely surprised at how light and quiet these cordless mowers are. Due to the price difference I was set to replicate my mates purchase with a 36v Ryobi and can heartily recommend them as a generally cheaper alternative.

The Bosch though is imho an even better unit. It is considerably lighter than the Ryobi (which is itself way lighter than my Victa), at 13kg even the Mrs can lift it up and down the terraces and mow the lawn.

It is also quiet enough that we were able to hold a conversation whilst I mow. (may be a pro or a con depending on your own circumstances)

Also, I prefer the plastic clipping catcher to the shade cloth that hangs out the back of the competition.

The only drawback i can see is that it will probably struggle on really large areas and is prone to cutting out if the lawn is epically overgrown, more so if the clipping catcher is full...

As it's so easy to use I can never see the lawn getting overgrown again so it really won't be a problem for me!

We love it! – We bought our Bosch Rotak 37 Li cordless about 3 years ago from Bunnings for $600 I think and we love it. It is just so convenient, quiet, and gets the job done. We don't have a large lawn but it takes us about 25 minutes to cut and we get it done on one charge. The charger gave up about 4 months ago but found one from some Sydney tool Company… Read more

for about $180.

Update 30/4/16

Our latest charger, number three, has now died and we are trying to negotiate with Bosch to see if they will supply another one. We reckon 3 chargers (recommended retail $249) in 4 years is a bit much. Otherwise we still love the mower which does a fantastic job. Easy to use, light, quiet, no petrol, oil, plugs to worry about a bit expensive but worth every cent

Disposable Mower – I loved this mower, worked well for almost three years. Then the battery didn't charge. Wasn't sure if it was the charger or the battery so I thought I would look at both. Bunnings no longer stocked this mower, so it took a while to get the prices. For both the charger and the battery... $520. So light and easy to use. Apparently it is disposable.

Acquired 2010, still going, just – I bort my Rotak 37 in 2010 and its still going. Of late its been hesitant to start so Im worried its on its last legs. Symptom - motor whirs for 1 second then stops. Try it a bit later and it starts. Battery seems fine, showing 3 bars. Hopefully it will last this spring and summer. Im on a 540sqm block with a decent lawn at rear and modest… Read more ·  2

front.

In terms of the last 3 yrs usage - no complaints. Its perfectly fine for modest lawns and modest tasks in suburbia. No petrol hassles! Light. Seems well-built. In its 4th year of operation it occasionally doesnt start, but still hasnt died. Fingers crossed!

Bosch Lawnmower – In my opinion, a cordless lawnmower does not seem to be a great product. Mainly because the battery has lifespan, nobody can assure after 2 years usage a fully charged battery is still a long lasting battery. I personally prefer a corded lawnmower, although the cable might short, but it can always buy an extension cable. Convenience, light, great design Battery lifespan

Great idea, but unreliable rubbish – I started off loving this lawnmower. No petrol, quiet, lightweight and with 2 batteries I could easily mow my entire lawn (about 450m2). Then after only 3 months - it stopped working. Completely stuffed. After a $300 repair (I had bought overseas so Australian consumer protection didn't apply) it was up and running again...but not for long. It's… Read more

now died for a second time. Same problem. Disappointing. I'm not going to waste money trying to fix it again. Going back to petrol until the technology improves! No petrol, quiet, lightweight Has broken down twice in 18months. DO NOT WASTE YOUR MONEY

Great mower but it didn't go the distance – I had a BR 34LI for just about 15mths. I like that its light and fast to move. It wasn't so great when I let the grass get long, or if it was wet. At the 11 month mark, it started to cut out. I took it back to Bunnings and waited 2 weeks to be told nothing was wrong. It was fine for another 1 month and then again started to cut out, and… Read more

refuse to restart for long periods. I thought it was overheating but discovered that it would restart only when I applied downwards pressure on the battery. Eventually, even that stopped working. Light and easy to use. Service department wasn't very thorough in my opinion
