Hello, Tl67 - We're sorry to see that you had some difficulty with your scrubber and ended up returning it! And we would have been happy to speak with you about this issue, so we could have tried to turn this experience around. This scrubber has a lock-on feature so that you do not have to keep holding the power button continuously while using the tool. To start the motor, simply fully depress the on/off button once and let go. This will make the brush start spinning. Make sure to press the button very firmly. To stop the motor, fully depress the on/off button again, and the brush will stop spinning. We are glad that you had no trouble with the return and appreciate you leaving us this review. And feel free to email us anytime at Reviews@RYOBItools.com, if you'd like to continue this conversation.
