RYOBI ONE+ HP 18V cordless dethatcher/aerator, Digi Mart USA News: A lawn that looks dull and weak may be suffering from compacted soil or a thick layer of thatch, both of which can limit the air, water and nutrients reaching the grass. According to a House Digest article, a single machine can address both problems, and the RYOBI ONE+ HP 18V dethatcher/aerator sold at Home Depot is one example.
The cordless, walk-behind tool includes two interchangeable reels. A scarifying reel with 16 stainless steel blades loosens and removes thatch and moss, while an aerator reel creates shallow openings in the soil.
The tool has a 14-inch working width, a brushless motor and four height settings to control how deeply the reels work. It also folds down for storage.
According to the report, Home Depot sells the tool-only version for around $399 without batteries or a charger. A kit with two 4.0 Ah batteries and a charger is priced at around $479.
Buyer feedback described in the article is mixed. Some shoppers say the tool aerates the lawn well and is easier than a manual dethatching rake, while many negative reviews cite poor battery life.
Some buyers reported needing multiple battery changes during a single job.
The article advises users to choose the correct reel for the task, since the reels cannot be used interchangeably, and to follow the manufacturer’s guidelines when changing them. It recommends that the mower have no power, with the start key and batteries removed.
It also suggests starting at the highest height setting and lowering it only if needed, because excessively deep settings remove more grass and draw more power from the battery.
The House Digest piece also notes limits: the tool only perforates the soil, which is less effective than core or plug aerators that remove soil plugs. For severely compacted soil, the article suggests a core or plug aerator or hiring professionals instead.
