It really is called the Quickie. This scrubber appliance from Amazon (Prime eligible) is transformative in my desire to unfuck my habitat. I really, really love this thing because my bathtub looks nice with very little effort on my part. Scrubbing the bathtub has always been abhorrent to me, even worse than mowing the lawn. For whatever reason, I hate it, to the point that I rarely do it. The thing was awful; I was afraid someone might open my shower curtain and go "aghhhhh!"
The Quickie has solved my bathtub issues. It is just a rotating brush on an extendable stick that you can charge up. Brilliant and well worth $40. Quickies FTW!
