Review (2/5): Just No.
The charging cable immediately got lost. Using this manually is a pain with the large handle. The “nubbins” don’t really do much for cleaning. Soap doesn’t have any sudsing action unless you put on so much that it defeats the purpose of cleaning. My dog was not afraid of this device, but she’s a pretty laid-back golden. Other dogs might be more skittish. A damp rag does a better job.
