A great tool in the cleaning arsenal
Pufchase process was smooth, follow-up outstanding, and a solid well-functioning produict. I used the brush attachment on the Synoshi to clean the tile and grout on the floor of a shower stall that had been neglected by previous owners of the house. The Synoshi did an admirable job to make the surface bright, clean, and like new. Battery life is outstanding, allowing cleaning for up to 45 minutes or more.
