Flymo Mighti-Mo Cordless Lawn Mower Review

This one’s definitely been on the cards for some time now, but it’s finally happened: Flymo have developed their very on cordless lawn mower to compete with Bosch’s ‘Li’ range, as well as battery powered mowers from manufacturers such as Black & Decker and Evopower.

Introducing the Flymo Mighty-Mo

At first glance this machine definitely looks the part, it’s very much Flymo ‘on steroids’ in it’s visual style, doing away with some of the trademark curvaceous and bulbous forms you’d typically associate with a Flymo lawn mower, and instead adopting a more hard edged, angular style. This has been done with good reason, to demonstrate just how much of a departure this machine is compared to the usual ‘small garden specials’ Flymo have traditionally produced.

But just what does this ‘departure’ consist of?

Well, with a 30cm cutting width this machine is still very much designed with small gardens in mind, but the obvious difference of course is that it suffers none of the ills associated with corded electric mowers. Instead you’ll be free to go in any direction you wish, without having to worry about running out of cord, or worse, cutting through it.

As a safe bet you can expect the 35 minute run time to allow you to cut a garden of 150 square metres on a single charge, allowing for several passes to make sure you’ve got an even cut. However, it’s fair to say that it will only be effective when the grass is already short (below an inch), if the grass is any longer than this then the Mighty-Mo ceases to be quite so mighty, and instead resorts to performing more like its air cushioned hover mowing cousins, ie. pretty ineffectively. The issue is one of stalling and clogging due to lack of power, and having to repeatedly reaching for the battery ‘safety key’ to cut the power to enable you to de-clog the underside of the deck could become very tedious very quickly. Not to mention that the battery cover is flimsy and is prone to breaking with continuous handling.

That isn’t to say the Mighty-Mo isn’t effective, but it’s certainly only for you if you’re prepared to mow you lawn regularly throughout the spring and summer, so that your lawn never grows beyond an inch at a time.


  • At 10kg this is nice and light for a cordless lawn mower, just about anyone will be comfortable pushing this around
  • Small and compact – easy to store and operate
  • Easy to operate cutting height adjustment lever
  • Up to date design and styling


  • No good for cutting overgrown grass
  • Battery cover is a little and the flimsy side
  • Spare battery is very expensive to buy!


This isn’t a bad attempt by Flymo to delve into the cordless lawn mower market, but it’s fair to say they probably have some way to go before they hit the nail on the head. The lack of power and ability to cut long grass are major flaws with the Mighty-mo, and given the sort of cash you need to part with in order to use it you really want these sorts of details sorted out first. It’s good, but it’s not great, we’d still recommend a Bosch cordless lawn mower over this, for the time being at least.
