Rank #7 in Best Cordless Lawn Mower 2026: Ten Ranked on Real Kits
RYOBI 18V ONE+ 33cm Lawn Mower (Battery & Charger Excluded)
Price and rating as shown on Amazon when we collected them. Both change.
The RYOBI OLM1833B is our number 7 best cordless lawn mower pick and the mower for the millions of owners already inside the ONE+ 18V system. The title says the important part up front: battery and charger are excluded. The mower itself brings a 33 cm cutting path, five heights from 25 to 65 mm, a 35 litre bag with a mulching plug and a cut to edge grass comb, at a claimed 7.7 kg without the battery, though the sheet lists 10.3 kg.
RYOBI rates it for up to 250 m2 with a 5.0 Ah battery, and the sheet quotes a 45 minute average life, with owners advising two batteries for longer work. With 2,472 ratings at 4.3, the evidence is strong. Everything on this page comes from the Amazon listing rather than our own testing.
