Will it work with any pressure washer?
Yes, provided the washer has a stubby gun fitted (of the correct type to worth with the supplied quick release) or a suitable adapter. But if you have a Karcher K-series machine, don't worry, these are probably the most common and hook straight up.
Does foam quality drop if water pressure is low?
Yes, poor flow and poor water pressure can result in weak foam - as can a lower end pressure washer. You want to have a 110 bar machine minimum, and even then a 130 bar machine will be better. Adding more detergent and adjusting the settings of a high quality foam lance like the Snow Commotion can sometimes get you through, but if you have a cheap pressure washer that cost less than a tank of fuel, this is going to always inhibit cleaning in general as well as foaming. Try and spend 150-300 gbp on a good pressure washer; the ones under 100 gbp may not be up to the job or always give you underwhelming results.
How do I clean the lance after use?
Fill the lance bottle with clean water, then run this through as if it were foam mixture. This is essential if using a sealant snow foam. If left unrinsed, your foam lance could fail if using a sealant snow foam.
How do you service the snow foam lance?
If you remove the pins in the plastic nozzle/grip, the whole lance comes apart easily to reveal the filter in the brass barrel section; this filter may be contaminated, full of old detergent or limescale deposits - new filters can be purchased on eBay.
Is there a warranty on the Snow Commotion lance?
We give a three month warranty on our snow foam lances to ensure they are working well without a manufactured defect. However, all lances are prone to failure due to dirt ingress, lack of servicing or incorrect use over time, so we don't give an indefinite warranty on this item.
