There is no single best mower in this set
The highest star line is the Flymo Speedi-Mo 360C, 4.6 from 6,673 reviews at about £110, and it is 36 cm. The Einhell GE-CM 43 Li kit is 4.1 from 6,758 reviews at about £239.94, so a huge sample is not a high score or a low price. The AdvancedRotak 40-650 is 4.0 from 99 reviews at about £209.94, the weakest star line here.
The top-pick label sits on the Flymo 38 cm: about £135, 4.4 from 4,468 reviews, a 45 litre box and a stated 10 m lead. The best-value label sits on the Speedi-Mo. If you still need a width before a name, use the buying guide.
A small flat lawn and a socket
For a modest flat lawn and a socket, start with the Speedi-Mo and the Einhell 37 cm. The Speedi-Mo is 36 cm and 1500 W. Reviewers call it light, and better at collecting than a hover. They also say the lowest cut stays too high for some lawns, and the long nose misses grass where fences meet. Box litres and cable length are not stated.
The Einhell GC-EM 1600/37 is about £114.99, 37 cm, a 38 litre box and a stated 10 m lead, with 4.5 from 298 reviews. There is no mulch plug in the bullets. Up to 700 m² is a seller claim. Skip both if you already hate a lead. The Flymo 38 cm is the nearer-to-40 cm corded alternative if you will live with a stated 10 m lead that reviewers call short.
If the listing must say 40 cm, or must stripe
If the title has to say 40 cm, you have two rows. The LawnMaster MEB1840M-01 is about £146.99, with a rear roller, a mulch plug, a 42 litre bag and a stated 10 m cable, at 4.1 from 317 reviews. Reviewers say it can stripe. They also say the cable is short, the handle is high if you are not tall, and the box is awkward. The AdvancedRotak 40-650 is about £209.94. It does not state a roller or a lead length. The item weight prints as 1 kg. Do not tidy that into a real weight.
If the job is stripes rather than the digits 40, the Hyundai HYM3800E joins the LawnMaster. It is 38 cm at about £158.31, with a stated roller and 4.2 from 3,914 reviews. How a roller bends grass is on the rear roller page. Neither mower is stated as self-propelled.
If you will not have a cable
Cordless belongs here when you refuse the lead. The Worx WG737E at about £229 is 37 cm and includes two 20 V 4.0 Ah packs and a charger. Up to 550 m² is a seller claim. The Einhell GE-CM 43 Li at about £239.94 is 43 cm, with two 4.0 Ah packs and two fast chargers. Long grass is where runtime collapses, about 10 minutes in one report. Several reviews report a two-pin charger rather than a UK three-pin.
The Ryobi OLM1833B at about £160.20 excludes the battery and the charger. Skip it if you do not already own 18 V ONE+ packs. The Litheli at about £109.99 states a 5.0 Ah pack and does not name a charger. The swift EB122C at about £134.99 is 22 cm, for a tiny side lawn only.
Common questions
Which listing is the strongest on stars and price?
The Flymo Speedi-Mo 360C, at 4.6 from 6,673 reviews and about £110. That is the strongest star line, and it carries the best-value label. The top-pick label is the Flymo 38 cm, at 4.4 from 4,468 reviews and about £135. The Speedi-Mo is 36 cm. Cable length and box litres are not stated, and reviewers mention a cut that stays too high and a long nose at fences. Strong stars do not rewrite the width.
Which one is actually 40 cm?
The Bosch AdvancedRotak 40-650 and the LawnMaster MEB1840M-01. The Bosch is about £209.94 with 4.0 from 99 reviews, and the listing prints the weight as 1 kg. The LawnMaster is about £146.99 with 4.1 from 317 reviews, a rear roller, a mulch plug, and a stated 10 m cable. Every other width here is something else, from 22 cm to 43 cm.
Which one stripes?
The Hyundai HYM3800E and the LawnMaster state a rear roller, and reviewers on both mention stripes. The Hyundai is 38 cm at about £158.31 with 3,914 reviews. The LawnMaster is the 40 cm row. No other bullet in this set states a roller. A Flymo comment about a replacement roller is not a Flymo specification.
Which cordless kit includes two batteries?
The Worx WG737E, two 20 V 4.0 Ah packs and a charger at about £229, and the Einhell GE-CM 43 Li, two 4.0 Ah packs and two fast chargers at about £239.94. The swift includes one 2.0 Ah pack. The Litheli states one 5.0 Ah pack and does not name a charger. The Ryobi includes neither.
Who should skip the Ryobi?
Skip the OLM1833B if you do not already own ONE+ 18 V batteries and a charger. The price is about £160.20 for the tool. Reviews say one battery lasts about 30 minutes and that long or damp grass is a poor match. It fits a small tidy lawn between raised beds when the packs are already on the shelf.
