Walmart offers the Shark Steam Pocket Mop, model no. S3501WMZ, for $39. Opt for free Site-to-Store pickup to avoid the 97 cent shipping fee. That's tied with last week's mention and the lowest price we could find for any Shark steam mop by $11. Sales tax is added where applicable. This electric steam mop features two washable microfiber cleaning pads, a 12.5" cleaning path, 180-degree swivel steering, and more.
