Compact but powerful, the Flymo Mighti-Mo delivers big performance and offers excellent manoeuvrability thanks to its 2Ah lithium-ion battery and cordless design. You’ll be able to cut up to 250m² on a single charge – approximately the area of a full-size tennis court – and thanks to the single-handle cutting height adjustment you’ll find it quick and easy to change between the five cutting heights, from 25mm to 65mm.

The large 30 litre grass box means less time spent emptying, and it’s also easy to access whenever you need to. Weighing just 9.9kg you’ll find it a breeze to move around and thanks to the carry handle it’s also simple to stow away, with the handles folding down for compact, space-efficient storage.

The battery takes just two hours to fully recharge, and for added safety and peace of mind this cordless lawnmower also comes with a removable safety key which disables it when not in use.

    Great product, best price.

    I've been using a small push mower for years and while I like the simplicity of a push mower (and the eco credentials) I have to admit this does a much better job. In the past, I've bought electric mowers but never bothered to use them as I hated having to faff with the cable when putting them away and they are too big and bulky. This little cordless one is a very good compromise as it's neat and light, but powerful enough to do 5 cuts of my city lawn on 1 charge. Robert Dyas had it for a great price too. I've only had it a month but it seems good quality and well built so far.

    small but powerful

    this mower is a joy to use, easy to manoevre yet powerful enough to get the job done. it needs to be emptied more often than our old mower, but that's not a problem for us. it was also very easy to assemble.

    Great little mower

    A light, speedy little lawn mower. It does our small lawns nicely and had no trouble chopping up the tomato and courgette plants before they were composted too. the box is very small, so frequent emptying is required. Battery life is around 45-60 minutes, but it does recharge fast and you don't need to fully charge before using the mower again. Recommend

    Ideal Cordless Mower

    I ordered this in store and it was delivered the next day. It works beautifully yet is light and compact. Really pleased with this purchase. Can't comment on the battery life as we have had a heatwave ever since I bought it!

    Flymo Mighty Mo - good mower, expensive batteries.

    This mower is light and portable and provides a good cut. No issues with that - though you do need to build quite a bit of it when it turns up. It is not plug and play. My criticism is the cost of additional batteries - which you will require to anything more than an average size lawn. They cost almost half the original price of the mower itself - seems more than a little greedy on the part of the manufacturer - especially if they are looking for repeat purchases or purchase of other products from their cordless range.

    Good so far

    Very difficult to choose what cordless lawnmower as reviews are always so mixed. Took a leap of faith on Flymo version as seemed what I wanted on paper. I've used it twice so far and has been very good and copes with my twisty uneven grass well. Height lever is a boon and lowest level cut is just low enough. Grass box fiddly to put together but rest is straightforward. Good idea to read instructions carefully for opening battery compartment etc. Pleased so far.
