"This thing is rock solid and a joy to use. For several years I'd borrow a commercial pressure washer and cleaning pad like this one from work for use on my driveway and pool deck. No longer working there, I decided to purchase my own as the cost to buy one was the same as me paying someone to do my house once. This thing is rock solid and will outlive everyone I know. It maneuvers well, and makes cleaning large swaths of ground a breeze. I can't fathom any improvement you'd see from spending more on one of these. This is the sweet spot for this kind of device."
