The Costco Electric Spin Scrubber—often branded under the “Kohree” or “Tilswall” names depending on the specific seasonal inventory—is a cordless, motorized cleaning tool designed to automate the scrubbing motion.

This allows users to reach high ceiling corners or low floor tiles without bending over.

Conversely, some reviewers note that while the scrubber is great for surface stains, it isn’t a “magic wand.” If the grout is deeply stained with mold, the scrubber may only clean the surface layer. Additionally, the weight of the unit when fully extended can be a bit awkward for some users, leading to arm fatigue if used for more than 20 minutes at a time.
Overall, cleaning results depend heavily on the type of detergent used and the frequency of cleaning; it works best as a maintenance tool rather than a one-time solution for years of neglected buildup.
