Let me start by saying this scrubber is a BEAST. After testing it on my grimy shower tiles and kitchen grease, I'm convinced it's worth every penny. The 550 RPM power mode obliterated years of soap scum that my old elbow grease couldn't touch.

The 9 brush heads are genius - I used the cone-shaped one for grout (life-changing!) and the flat scrubber for my bathtub. Pro tip: The 90° angled head makes cleaning shower corners stupid easy. No more awkward wrist angles!

Battery life shocked me - cleaned my entire bathroom (tub, tiles, sink) on one charge. The USB-C charging is convenient, though the indicator light is frustratingly dim like other reviewers mentioned.

The auxiliary handle? Absolute MVP. Without it, the scrubber does tend to "hop" on vertical surfaces. With it? Total control. My 5'2" mom could use it comfortably for her backsplash.

Watch out for two things: 1) Don't press too hard - it will auto-stop (safety feature, not a defect) 2) The hanging solution is weak - I ended up screwing the plate into studs like another reviewer suggested.

Compared to my old corded scrubber? Night and day difference. No tripping over wires, no weak motor bogging down. At $54 with all these attachments, it outperforms models twice the price. Just wish replacement brushes were easier to find!
