SLENJADFIN Cordless Portable Washer Compatible with Makita 18V Battery — Brushless 380W, 6‑in‑1 Nozzle, Tool Only

The SLENJADFIN cordless portable washer is a lightweight, Makita 18V-compatible handheld cleaning tool with a brushless motor and 6-in-1 nozzle for versatile on‑the‑go cleaning.

Designed for homeowners, car enthusiasts and outdoor workers who already own Makita 18V batteries, this compact washer delivers steady power from a 380W pure-copper motor while eliminating cords and fixed power sources. It pulls water from buckets or garden supplies, offers multiple spray patterns and includes a foam tank and long intake hose for flexible, effective cleaning around the house, yard, or campsite.

How powerful is the washer and what does it clean effectively?

The SLENJADFIN uses a 380W pure copper motor that supplies consistent rotational force for daily tasks without the noise and bulk of larger pressure washers. It’s optimized for light- to medium-duty cleaning rather than industrial blasting.

• 380W pure copper motor for dependable output
• Brushless design for longer life and efficient energy use
• Best for cars, patios, fences, walls, floors and outdoor furniture
• Not intended for heavy-duty industrial oil or concrete removal

Will my Makita battery work with this tool and how long will it run?

The unit is compatible with common Makita 18V battery models (BL1860, BL1850, BL1840, BL1830, BL1815). Runtime depends on battery capacity and cleaning intensity; higher-capacity batteries provide longer operation for larger jobs.

• Supports Makita BL1860/BL1850/BL1840/BL1830/BL1815 batteries
• Use your existing charger and cells to avoid extra cost
• Runtime varies with battery mAh and nozzle selection
• Brushless motor helps maximize battery efficiency

What spray options and accessories come with the washer?

The washer includes a rotating 6-in-1 nozzle offering 0°, 15°, 25°, 40°, fan spray and shower modes, plus a matched foam tank for detergent application. The nozzle choices suit concentrated scrubbing to gentle rinsing for delicate surfaces.

• 0° and 15° for focused, high-impact cleaning
• 25° and 40° for general rinsing and surface washing
• Fan spray and shower modes for wide, gentle coverage
• Foam tank attachment for suds and improved cleaning power

How does the water intake work and where can I use it?

The washer includes a long 197-inch intake hose with a filter to block debris, letting you draw water from buckets, rain barrels, rivers or connect to a standard garden faucet with the 3/4-inch threaded connector. This flexibility makes it useful for both remote outdoor jobs and backyard tasks.

• 197-inch hose for remote water sources
• Inline filter reduces clogging and protects the pump
• 3/4-inch connector for standard garden hose and faucet use
• Portable design supports jobs away from power outlets

Who is this for? The SLENJADFIN cordless portable washer is aimed at owners of Makita 18V battery systems who need a light, mobile cleaning solution: car owners, apartment dwellers, gardeners, RV and boat owners, and anyone who wants cordless convenience for patios, fences, decks and light-to-moderate outdoor cleaning. It’s not a replacement for commercial high-pressure washers but a practical, space-saving option for everyday maintenance and mobile tasks.
