Works great!

I bought this surface cleaner at the same time as a gas powered Simpson pressure washer. It doesnt work Not on the Simpson or my small 2400 psi electric power washer.  The nozzles will not spin under pressure. Turn the pressure off, they spin freely by hand. Pressure on, they dont move at all. It is obvious the water pressure is pushing on the hub/bushing and they keeps the nozzles from spinning. I've lubricated it. No joy.

Conceptually this product saves a lot of time. The bad thing is that time saved is a one time affair. These are single use surface cleaners that are unserviceable and sadly in two cases have failed their second attempt at use.  One was RMAd.  The same unit was used once and subsequently failed to spin on second use a year later.  The price point seems to be aimed at the homeowner market so these are a once a year thing, at least for me.  I'd stay away from this model and look elsewhere.

Will not last!!!!  I have average 2 car garage driveway and small amount of sidewalk and small back patio. Cleaned it all exactly once. Came back this year and the bushings are work to the point it wwont spin fast enough to clean. Checked/cleaned tips to no avail. Avoid this piece of equipment.

It stopped spinning after 3 uses. It's not clogged, but it's leaking through the "T" connection. Has 2 plastic washers/bushings that are not available from Simpson's!! Now have a piece of junk! Called Simpson's customer service and they just don't care to provide any service.

Real handy add on for your washer

Works terrific! Exactly what you need if you've got a lot of concrete to clean.

It worked in a marvelous way! Easy to use and it did the job well! Everyone was soooo impressed with the job completed.

Cleaned our concrete patio and wood deck floor with this attachment. Very easy to use and it did an amazing job. Everything looks new again!

Used on travertine patio. Works incredibly well to get into crevices. Very well made and easy to use with my Simpson power washer. Excellent value.
