Acts like a hovercraft so wheels aren't necessary. Did a great job on my omni stone driveway. Used this on my stamped and stained concrete patio.
This one cleans even better. We have a gas powered 2800psi pressure sprayer and was amazed at how well it did. All metal with extra nozzles & extension wands. Amazing cleaner, quieter than pressure washer with nozzle tips.
This product was advertised as 16 inches. While the plastic housing with the brush is 16 inches the spray rod is less than 13 inches wide. There is some internal blockage that prevents the unit from working.
The nozzles are bent and misshapen so they won't spray the ground. The quick connect tip was rusted and wouldn't attach any longer. Cheap nylon washer.
