Brushless describes how a tool’s motor is built, not its voltage. In RYOBI’s explanation, brushed motors transfer current through carbon brushes and a commutator; brushless motors use magnets and electronic switching. That design distinction can matter for wear and demanding work, but RYOBI’s published side-by-side example compares 18V ONE+ impact drivers—not matched 40V tools. For a 40V purchase, compare the particular tools, their features, battery kits, and price rather than assuming the brushless label proves one is the better choice.
What changes inside a brushed and brushless motor?
The names refer to the motor’s method of transferring and controlling electrical current. RYOBI describes the two designs this way:
| Motor type | How RYOBI describes it | Practical distinction |
|---|---|---|
| Brushed | Carbon brushes make contact with a spinning commutator to transfer current. | The contact creates friction, and RYOBI says the brushes wear over time. The explanation does not establish a fixed service life or failure schedule. |
| Brushless | Magnets and solid-state electronics replace the brush-and-commutator arrangement; a circuit board adjusts power output to the material. | It uses electronic control rather than brushes rubbing against a commutator. RYOBI characterizes brushless motors as more efficient and better suited to demanding use, but that is manufacturer guidance, not a quantified 40V comparison. |
Neither term tells you the tool’s voltage, battery capacity, cutting or driving ability, or included accessories. Those are separate product specifications.
What does RYOBI’s 40V evidence show?
RYOBI’s brushed-versus-brushless explainer includes a side-by-side comparison of 18V ONE+ impact drivers. It is not a matched test of 40V tools, so its example cannot establish a percentage performance advantage for a 40V brushless tool.
#1 Best Overall
- CARBON FIBER COATED
- Works with all RYOBI 40-Volt lithium-ion tools and batteries
- Attachment capable: works with RYOBI expand-it attachments
- Variable speed with 2-speed trigger for more control
- Brushless motor for maximum power and durability
RYOBI does list brushless tools in its 40V range. For example, the company’s 40V HP Brushless 17-inch String Trimmer, model RY402011BTL, is listed with a claim of up to 67 minutes of runtime using a 40V 6Ah battery. That is RYOBI’s stated maximum under its product-page conditions, not an independently verified runtime guarantee for every yard, battery condition, or trimming workload.
RYOBI also describes 40V HP technology as combining a brushless motor, advanced electronics, and lithium battery technology. Its 40V HP Edger page says the 40V system has over 85 products. That catalog count is the company’s statement, and product availability and counts can change.

- Ryobi 40Volt HP Brushless Leaf Blower; 180 MPH; 800 CFM; Cordless; Handheld
These examples establish that brushless models are part of the 40V lineup; they do not provide a same-tool, same-battery comparison against a brushed 40V counterpart. A general motor-design explanation should not be mistaken for a controlled comparison of two particular tools.
How to choose between actual 40V tools
Start with the work you need to do. A trimmer, edger, auger, and other tool categories have different jobs, and a motor label alone cannot tell you which product suits yours.

Rank #3
- Stens replacement parts have become a favorite among lawn and landscape professionals thanks to exceptional performance.
- Match the tool to the task. Check the tool category, working width or other task-specific specifications, and features that affect the job.
- Compare performance claims on equal terms. Look for the stated workload, battery, and test conditions behind power or runtime figures. Do not treat claims made under different conditions as a direct head-to-head result.
- Check the battery and charger kit. RYOBI lists the RY402011BTL as a tool-only option and also shows an option with a 6Ah battery and charger. Confirm the exact listing and included items before buying; a tool-only price does not include the cost of a battery and charger you may need.
- Weigh handling and task features. Consider the controls, adjustment options, ergonomics, and other features relevant to how and where you will use the tool.
- Compare the complete purchase cost. Compare current prices only after accounting for the battery and charger you need, not just the motor type or bare-tool price.
When is brushless worth considering?
Brushless is a sensible feature to weigh when you expect demanding or frequent use, or when reducing brush wear is important to you. RYOBI presents the design as more efficient and suited to demanding work, but the available 40V examples do not establish how much longer a particular brushless tool will run, how much more work it will do, or whether it is worth a particular price premium over a comparable brushed model.
If the tools you are considering differ in category, features, or battery kit, those differences may matter more to your decision than the motor label. Compare the exact models and their included equipment before paying extra for brushless.
