The ZYMY Cordless Pressure Washer Gun is priced at £29.99, while the Cordless Pressure Washer 21V is slightly cheaper at £28.99. Both products offer cordless functionality, making them ideal for outdoor cleaning tasks without the hassle of power cords. The ZYMY model boasts a higher pressure rating of 26 bar, compared to the 21V model’s 62 bar, indicating it might deliver a more powerful clean for stubborn dirt and grime.
Performance Comparison
In terms of performance, the ZYMY Cordless Pressure Washer Gun offers a high-pressure output of 26 bar, with a flow rate of 3.5 litres per minute. This allows it to effectively tackle mud and grime, especially on vehicles. Conversely, the Cordless Pressure Washer 21V delivers an impressive 62 bar, equating to 899 PSI, which is designed for high-efficiency cleaning across a wider range of surfaces. The extended spray distance of up to 10 metres on the 21V model enhances its versatility for outdoor use, making it a strong contender for larger cleaning jobs.
Battery Life and Charging
Both products come equipped with two rechargeable batteries, ensuring extended runtime during cleaning sessions. The ZYMY model features dual 2.4Ah batteries, providing twice the runtime compared to standard battery pressure washers. This is particularly advantageous for users looking to clean multiple vehicles or larger areas without interruptions. The Cordless Pressure Washer 21V’s batteries allow for up to 30 minutes of continuous use, with a fast charging capability of 2-3 hours. While both models excel in battery efficiency, the ZYMY's longer operational duration may appeal more to those needing extended performance.
Cleaning Flexibility
The ZYMY Cordless Pressure Washer Gun is designed with a complete car washing kit that includes a jet wash gun and two nozzles, allowing for diverse cleaning applications. It can transform into a foam cannon for pre-soaking, which is ideal for deep cleaning vehicles. On the other hand, the Cordless Pressure Washer 21V features a 6-in-1 nozzle with multiple spray settings, including shower mode and various angles for different cleaning tasks. This adaptability makes it suitable for a range of outdoor surfaces, from cars to garden furniture.
Portability and Design
Both models prioritise portability, with a cordless design that liberates users from being tethered to a power source. The ZYMY is lightweight and designed for ease of use, making it simple to transport around driveways and gardens. The Cordless Pressure Washer 21V also emphasises a lightweight design, making it easy to manage during cleaning routines. Each model's ability to draw water from various sources, such as buckets or ponds, adds to their versatility for outdoor cleaning.

The ZYMY Cordless Pressure Washer Gun comes with a range of accessories that enhance its functionality, including a 5-metre hose and extension rod. This setup allows for greater reach and versatility during cleaning tasks. The Cordless Pressure Washer 21V, meanwhile, includes a foam bottle that aids in removing stubborn dirt, making it particularly effective for car washing and other cleaning tasks.
