Shark Steam Mop S4501D
$79.99as of Jul 8

The Shark Steam Mop S4501D delivers effective cleaning using only steam and water, making it safe for homes with kids and pets. Reviewers praised its rotating scrubbing heads that eliminate the need for manual scrubbing, and its quick heat-up time of about 30 seconds. The mop is easy to assemble and use, with a large water tank that lasts through multiple cleaning sessions. However, some reviewers noted it lacks adjustable steam settings and produces steam only when the handle is actively pumped, which can be tiring for larger areas. It's best suited for users seeking a straightforward, chemical-free floor cleaning solution rather than those needing versatile or continuous steam options.

Strengths
  • Uses only water and steam for chemical-free cleaning
  • Rotating scrubbing heads do the hard work without user scrubbing
  • Heats up quickly, with a 30-second warm-up time
Watch-outs
  • Only has one steam setting instead of adjustable levels
  • Steam only produced when handle is pumped, not continuous

How they stack up

Shark Steam Mop S4501D

The S4501D provides rotating scrubbing heads that eliminate manual scrubbing, a feature not found in the Shark S4003D, which requires pump activation. However, the S4003D is lighter and easier to set up, while the S4501D only offers one steam setting instead of adjustable levels like the Bissell Deluxe 1800A.
