DO NOT BUY THIS!!

16 days ago
Failed after 4 uses, was less than a week outside of the 90 day warranty and Simpson will not stand behind it. I'll be filing reports with the NY Attorney General and FTC. This is a known issue and they keep selling it, and not properly supporting customers.

Terrible bearing swivel.

2 years ago
Doesn’t last bearings are basically unserviceable. Can pull out cartridge and grease bearings and works fine for a while. From the factory bearings have hardly any grease. No easy way to do basic maintenance without spending hours of down town.

No, I do not recommend this product.

Great time saver.

Excellent Surface cleaner. Amazed at how much time this saved me when cleaning my driveway. It is so much faster than using just the wand.
