Our take
The RYOBI P1109BTL is a documented 16-inch push mower for shoppers who want a narrower cordless deck and already have, or are willing to purchase separately, compatible 18V ONE+ batteries. The manufacturer specifies bagging and mulching, seven cut-height positions from 1.5 to 4 inches, and folding handles. Its stated runtime is up to 40 minutes with two 4.0 Ah batteries, but those batteries and a charger are not included with this tool-only configuration. This review compares maker-documented features; it does not report a mowing test.
A buyer who values a narrower push mower, already owns RYOBI 18V ONE+ batteries or plans to buy them separately, and can use bagging or mulching without requiring documented side discharge..
Look elsewhere if you require self-propelled drive, a battery and charger in the same package, a confirmed side-discharge mode, or a wider 21-inch deck. The runtime and area guidance should not be treated as guarantees for a particular lawn.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- The 16-inch deck is narrower than the 19- and 21-inch decks in this catalog, giving route width a concrete comparison point.
- RYOBI documents bagging and mulching, a grass catcher, and a mulch plug for the P1109 mower.
- Seven height positions and folding handles provide documented cut adjustment and vertical-storage options.
What to weigh up
- The product page says batteries and charger are not included, so a new ONE+ user must account for those separate items.
- The mower is push-only; it does not provide powered forward movement on slopes or longer passes.
- RYOBI documents bagging and mulching but does not confirm side discharge or a numeric catcher capacity for this model.

Full review: how the features affect your choice
What the features mean for you
A middle-width push deck
RYOBI lists a 16-inch cutting deck for the P1109BTL. That sits between the very narrow 12- and 14-inch models in this catalog and the common 19- to 21-inch decks. A narrower deck can be easier to route through a confined gate or around closely spaced obstacles, while it covers less width on each pass than a larger deck. Width alone does not establish how long a particular lawn will take, so treat the measurement as a fit constraint rather than a performance promise.
Tool-only battery shopping
The exact P1109BTL page identifies the RYOBI 18V ONE+ HP brushless platform and explicitly says batteries and charger are not included. The mower's up-to-40-minute statement is based on using two 18V ONE+ 4.0 Ah batteries, not on a battery set supplied with this offer. Owners who already use the platform may find that configuration useful; first-time buyers should include a compatible battery pair and charging equipment in their comparison. The offer title also says tool only, but a current seller listing still needs its own package check.
Bagging and mulching with seven heights
The manufacturer describes two clipping arrangements: bagging and mulching. It lists a grass catcher and mulch plug, and the single-point adjustment provides seven positions from 1.5 to 4 inches. Those details let a shopper compare the mower with models that document a side-discharge chute or a different height range. RYOBI does not give a numeric bag volume in the product information reviewed here, so buyers who need a specific collection capacity should check the manual and current package rather than infer it from the deck size.
Runtime and area are conditional claims
RYOBI says the P1109 can run for up to 40 minutes using two 4.0 Ah ONE+ batteries and describes it as suited to up to one-third acre. These are manufacturer guidance statements, not measured outcomes for a specific lawn. Grass height, terrain, battery condition, selected cutting height, and operating conditions can change the work completed on a charge. The payload preserves the maker's original wording in the fact note instead of converting the acreage claim into a precise square-foot threshold or treating the runtime as a hard minimum.
Storage and listing checks
RYOBI documents folding handles for vertical storage, a useful feature when floor area is limited. The source does not specify a deck material in the product facts reviewed for this article, and it does not document side discharge; those remain unknown rather than assumed absent. RYOBI's model page supports the P1109BTL identity and its tool-only configuration, but it does not prove the present condition or contents of every Amazon offer. Before ordering, compare the model code, included catcher and mulch plug, battery and charger exclusions, seller condition, and return terms.

Before you buy
Are a battery and charger included?
No. RYOBI's P1109BTL page says batteries and charger are not included. Its up-to-40-minute figure uses two 18V ONE+ 4.0 Ah batteries, so buyers need to supply a compatible pair and charger separately.
Can this mower bag and mulch?
The manufacturer lists bagging and mulching and identifies a grass catcher and mulch plug. It does not document a side-discharge mode for this product page.
Is the P1109BTL self-propelled?
No. RYOBI identifies the P1109BTL as a push mower. The operator supplies the forward movement; the 18V battery system powers the blade.
