Surface cleaner with my pressure washer
I have a 2750 psi Excell power washer. I am looking for a surface cleaner that will help to speed the cleaning of my concrete drive and walks. I have seen a Briggs model at Lowes for $69 and another model from Whirl-A-way on several websites. This model runs about $100-$110. Has anyone used either of these? Any reason to spend the extra for the Whirl-A-Way? Any opinion are appreciated.
