Cordless Washer vs Surface Cleaner
Power source
The DEWALT 20V MAX Cordless Power Cleaner operates independently using a 20V battery system, as indicated by its cordless design. This allows you to clean without being tethered to an electrical outlet or generator. In contrast, the DEWALT 18-Inch Cold Water Surface Cleaner is an accessory that requires connection to a separate pressure washer. It does not have its own power source. You must already own a compatible machine to use this surface cleaner. The cordless unit offers complete mobility, while the surface cleaner is dependent on another device for operation.
Pressure rating
The DEWALT 20V MAX Cordless Power Cleaner delivers a maximum pressure of 550 PSI. This level is suitable for light-duty tasks like patio furniture or car washing. The DEWALT 18-Inch Cold Water Surface Cleaner is rated for pressure washers up to 3700 PSI. This accessory is built to handle high-pressure streams, significantly exceeding the output of the standalone cordless unit. If you need intense cleaning power for tough grime, the surface cleaner supports much higher pressure levels when paired with a powerful washer. The cordless cleaner is limited to its internal 550 PSI limit.
Flow rate
The DEWALT 20V MAX Cordless Power Cleaner provides a flow rate of 1 GPM. This water volume works with the 550 PSI to create a gentle cleaning stream. The DEWALT 18-Inch Cold Water Surface Cleaner does not list a specific flow rate in its specifications. Its performance depends entirely on the flow rate of the pressure washer it connects to. Typically, surface cleaners require higher GPM to rotate their nozzles effectively. Without a stated GPM for the surface cleaner, the cordless unit has a defined water output, while the surface cleaner's water usage remains variable based on your existing equipment.
Intended use
The DEWALT 20V MAX Cordless Power Cleaner is a standalone tool designed for general cleaning tasks. It can draw water from any fresh water source, making it versatile for on-the-go use. The DEWALT 18-Inch Cold Water Surface Cleaner is specialized for flat surfaces like driveways, sidewalks, and decks. It is an attachment, not a complete machine. You use the surface cleaner to get uniform results on large, hard surfaces. The cordless cleaner is for varied items, while the surface cleaner is for specific, broad-area flat cleaning.
Water temperature
The DEWALT 18-Inch Cold Water Surface Cleaner is explicitly designed for cold water pressure washers only. Using it with hot water could damage the unit. The DEWALT 20V MAX Cordless Power Cleaner does not specify a water temperature restriction in its features. It draws from fresh water sources, implying standard ambient temperature water is suitable. If you plan to use hot water for degreasing, the surface cleaner is not compatible. The cordless unit appears more flexible regarding water temperature, as it is not limited to cold water specifications.
