Scrub Master Electric Spin Scrubber vs HOTO Electric Spin Scrubber

The Scrub Master is the better pick for raw scrubbing power and runtime, with a 450 RPM motor, about 120 minutes of battery and eight brush heads. The HOTO wins on design: an IPX7 waterproof head, an extendable handle that reaches about 51 inches so you don't bend, and a lighter main unit. Reviewers of both like the cordless convenience; owners of long-handled scrubbers consistently say the extension rod saves their back on tubs and floors, while high-RPM units like the Scrub Master cut through grout faster.

• Choose the Scrub Master if you want the most scrubbing force and the longest runtime, and you mostly clean tubs, sinks and grout at close range.
• Choose the HOTO if you want to clean floors and shower walls without bending, and you value a fully waterproof head and a lighter tool.
