Makita DUB185Z 18V Blower Cordless vs Makita 18V Brushless Blower DUB184Z Skin Only

Power and Performance

The Makita DUB185Z 18V Blower Cordless delivers a maximum air speed of 98 m/s, making it the more powerful option in terms of pure velocity. The Makita 18V Brushless Blower DUB184Z, by contrast, reaches a maximum air velocity of 52.1 m/s, which is considerably slower. However, the DUB184Z prioritises air volume over velocity, delivering 13.0 m³/min for more sustained blowing capacity. The DUB185Z achieves its higher speed through an increased air outlet diameter, which drastically boosts air volume for higher blowing efficiency. For jobs requiring maximum force and faster cleanup, the DUB185Z's superior air speed gives it the edge in raw performance metrics.

Control and Ease of Use

The DUB184Z offers variable speed control triggered by a squeeze lever, with an additional cruise control lock-on feature for extended operation without constant finger pressure. This makes it ideal for longer sessions and gives operators flexibility in power application. The DUB185Z, by contrast, is designed as a compact and lightweight tool for single-handed operation, prioritising manoeuvrability and ease of handling over ergonomic features. The DUB184Z includes a shoulder belt for distribution of weight during use, whereas the DUB185Z's lightweight profile is its key advantage. For users who value control and convenience during extended work, the DUB184Z's variable speed and support features are superior, though the DUB185Z suits those seeking simplicity and portability.

Motor and Speed Control Technology

The DUB184Z features brushless motor technology, which Makita's engineers have optimised to deliver constant speed control—the motor applies additional power to maintain performance even under load. This technology delivers up to 18,000 rpm and uses an in-line fan design to enhance overall tool balance. The DUB185Z uses a traditional brushed motor design, as is typical of its class. The brushless design in the DUB184Z represents a technological upgrade that extends motor life, reduces maintenance, and provides more stable performance across varying conditions. The constant speed control feature is a notable advantage for professional users dealing with changing debris types and coverage areas. If durability and advanced motor technology matter to your use case, the DUB184Z holds the advantage.

Battery Runtime and Compatibility

The DUB184Z delivers approximately 12 minutes of runtime when paired with an 18V 6.0 Ah battery (not included), making it adequate for light to medium clearing tasks. Both tools are sold as skin-only units, meaning battery and charger are not included, so comparison here focuses on stated capability. The DUB184Z is specifically incompatible with Makita's G Series batteries, limiting your accessory options, though it does work with the broader 18V LXT slide-type battery range. The DUB185Z's runtime specifications are not detailed in available product information, which may indicate a shorter typical use window or suggest it functions within different operational parameters. Battery compatibility and stated runtime favour the DUB184Z for users planning extended work sessions or multiple jobs.

Price and Value Proposition

At A$135.90, the DUB185Z is less than half the price of the DUB184Z at A$279.00—a significant cost difference. The DUB185Z ranks as #3 on the best-seller list in its category, whilst the DUB184Z sits at #50, suggesting broader market appeal and value perception for the lower-priced model. For budget-conscious buyers seeking a cordless blower for occasional use, the DUB185Z represents exceptional value. However, the DUB184Z's higher price reflects its brushless motor, constant speed control, and additional convenience features. The DUB185Z's popularity may reflect its role as an accessible entry point into cordless blowing, whilst the DUB184Z appeals to more demanding users willing to invest in technology and control.

Environmental and Maintenance Considerations

The DUB185Z emphasises zero emissions and reduced maintenance as key benefits, eliminating the need for petrol, oil, and associated fuel handling. As a battery-powered cordless tool, it produces no combustion emissions during operation, making it environmentally friendly for residential or sensitive environments. The DUB184Z, also battery-powered and cordless, shares the zero-emissions benefit of its counterpart. Both units eliminate the maintenance burden of fuel mixing, spark plug replacement, and oil changes associated with petrol alternatives. The brushless motor in the DUB184Z actually reduces internal wear compared to brushed designs, making it lighter on maintenance over time. Neither tool requires the environmental precautions of petrol equipment, though the DUB184Z's brushless design may offer slightly longer intervals between maintenance checks.

User Build and Handling

The DUB185Z prioritises portability with a compact, lightweight design engineered for single-handed operation, making it the clear choice for users who value manoeuvrability and reduced fatigue during yard work. Its larger outlet diameter enhances efficiency despite its modest size. The DUB184Z is a more substantial tool, equipped with a shoulder belt to support its weight during extended use—a recognition that professional or heavy-duty applications benefit from proper weight distribution. The in-line fan design in the DUB184Z enhances balance despite its more complex design. For light, quick cleanup tasks where you'll move between multiple garden zones, the DUB185Z's compact profile is advantageous. For sustained clearing work covering larger areas, the DUB184Z's ergonomic support and balance engineering make extended use less physically demanding.

Which should you buy?

Choose the Makita DUB185Z 18V Blower Cordless if you need a budget-friendly, lightweight blower for occasional yard cleanup, quick debris removal, and single-handed operation. Its 98 m/s air speed delivers impressive clearing power in a portable package, and at A$135.90 it offers outstanding value. Choose the Makita 18V Brushless Blower DUB184Z if you tackle regular, sustained clearing tasks and value variable speed control, constant motor performance, and ergonomic support features. The DUB184Z's brushless motor technology, cruise control, and shoulder belt make it ideal for professional or demanding residential use where battery power and motor control matter. The DUB185Z's higher bestseller ranking reflects its broad appeal as an affordable entry point, whilst the DUB184Z serves users investing in technology and convenience for more demanding applications.
