Cordless high-pressure washer 80BAR DHW080ZK

Cordless Mobile Cleaning Power

Imagine a situation where you need to wash a car in the garden, clean a terrace after winter, or rinse mud off construction tools, but access to an electrical outlet is impossible or inconvenient. This is exactly where the Makita DHW080ZK cordless high-pressure washer changes the game. The device requires no connection to the mains or search for extension cords – its heart is a dual 18V LXT battery system (kit includes body only, without batteries and charger), providing full mobility. A maximum pressure of up to 80 bar allows effective removal of stubborn dirt, such as dried mud, algae on sidewalks, or dust from facades. For installers or gardeners, this means saving time on laying cables and greater freedom of movement around the object.

Two Operating Modes and Application Flexibility

A key advantage of this model is the ability to adjust power to the specific task by selecting the appropriate operating mode. The device offers two working pressure settings: 30 bar in low mode and 55 bar in high mode. Why is this important? The lower pressure mode (approx. 30 bar) is ideal for gently rinsing sand off tires, washing sensitive surfaces, or cleaning garden plants where too strong a jet could cause damage. Meanwhile, the high mode (55 bar) is effective for removing tough stains from concrete or wood. Water flow ranges from 240 l/h to 330 l/h (depending on the mode), ensuring sufficient impact force while maintaining reasonable water consumption.

The device's operating time depends directly on the selected power and the capacity of the batteries used. When using two 5.0 Ah batteries (e.g., BL1850B), in low-pressure mode (30 bar), the device operates for approximately 28 minutes, allowing longer cleaning of large surfaces without needing to replace power sources. However, if maximum impact force is required (55 bar mode), this time reduces to about 12.5 minutes. It is worth noting that using higher-capacity batteries (e.g., 6.0 Ah) can extend this time to approximately 34 and 15 minutes respectively, giving the user flexibility in planning cleaning tasks.

Construction and Ready-to-Mount "Out of the Box" Design

The washer is designed to be ready for operation immediately after removal from the transport case. The kit includes a plastic spray lance (lightweight and corrosion-resistant), a large variable nozzle allowing adjustment of the water jet width from a narrow stream to a wide spray, and a complete set of hoses. The high-pressure hose length is 5 meters, providing sufficient reach for working around a car or small terrace without constantly moving the unit. Importantly for professionals working in the field, the device features a self-priming system – it can draw water directly from a tank (e.g., a barrel) located up to 1 meter below the washer level, eliminating the need to connect it to a pressurized tap.

The device tolerates inlet water temperatures up to 40°C, allowing the use of warm water from solar tanks or sun-heated garden containers – warm water dissolves fats and oils much better than cold water. The total weight is approximately 6.4 kg (body only), with external dimensions of 438 x 218 x 269 mm, making it easy to carry even with one hand and fit into a passenger car trunk. The noise level during operation is approximately 71-83 dB(A), which is acceptable for this type of equipment and does not require specialized hearing protection for short-term outdoor use.
