DeWalt Snow Foam Lance Review
The DeWalt Snow Foam Lance (model DCPR320) promises professional-grade foam for pressure washers. This review examines its build, foam output, and value against key rivals.
Quick answer
The DeWalt Snow Foam Lance is a solid, well-built attachment for thick, clingy foam. Its adjustable dial and brass fittings offer durability, but it's best suited for gas pressure washers above 1,800 PSI. For electric washers, the Karcher Foam Nozzle is a better match.

Who is the DeWalt Snow Foam Lance for?
This lance is for users with a gas or high-PSI electric pressure washer (1,800 PSI and above) who want to apply a thick, professional-grade snow foam. It's a good upgrade from basic included nozzles, offering better control over foam thickness.
Performance and Foam Quality
The DeWalt lance produces a thick, clingy foam that adheres well to vertical surfaces, allowing for effective dwell time. Owner reviews consistently praise its ability to create a "snow-like" blanket. The adjustable dial lets you fine-tune the mix from a light pre-wash to a heavy foam.
Build Quality and Durability
The lance features a brass quick-connect and nozzle, which are resistant to corrosion. The body is a sturdy plastic, though the bottle neck is a known weak point if over-tightened. Overall, it feels more robust than many budget lances.
Alternatives to Consider
For electric pressure washers under 1,800 PSI, the Karcher Foam Nozzle is more effective. For professional use, the MTM Hydro PF22.2 offers a higher-grade aluminum build. The Ryobi Foam Cannon is a good budget alternative for Ryobi owners.
FAQs
Will the DeWalt Snow Foam Lance fit my pressure washer?
It fits most pressure washers with a standard 1/4-inch quick-connect fitting. Check your washer's connection type before buying.
What PSI is best for this foam lance?
It works best with pressure washers rated between 1,800 and 3,000 PSI. Lower PSI may result in thinner foam.
Can I use any car shampoo in the lance?
Yes, but thicker, dedicated snow foam shampoos produce the best results. Dilute according to the shampoo instructions.
How do I adjust the foam thickness?
Turn the dial on top of the lance. A higher number adds more soap, a lower number adds more water.
Is the bottle plastic or glass?
The included bottle is plastic. It is durable but can crack if over-tightened.
Does it come with a warranty?
Yes, DeWalt offers a 1-year limited warranty against manufacturing defects.
Is this better than the Karcher foam nozzle?
For high-PSI gas washers, yes. For low-PSI electric washers, the Karcher is often better.
Can I use it with hot water?
DeWalt does not recommend using it with hot water above 140 degrees Fahrenheit, as it may damage the plastic.
How do I clean the lance after use?
Rinse the lance and bottle with clean water. Run clean water through the nozzle to prevent clogging.
Does it come with a spare bottle?
No, it comes with one 32-ounce bottle. Spare parts are available from DeWalt.
Our verdict
The DeWalt Snow Foam Lance is the best overall for users with high-PSI washers who want thick foam. For budget-conscious buyers or those with electric washers, the Karcher Foam Nozzle is a better fit. The DeWalt's build and adjustability justify its price.
