Dyson PencilWash: Slim Cordless Cleaner Adds Mopping for $349

Mar 20th 2026

Dyson's new PencilWash keeps the pencil thin cordless form factor and adds a built in mop head with fresh water cleaning for $349, offering a lightweight wet cleaning option with about 30 minutes of runtime.

  • PencilWash keeps the PencilVac's ultrathin design while adding mopping with Dyson's Submarine cleaner head that houses a mop roller, clean and dirty water tanks, and cleaning solution.
  • The unit weighs 4.9 pounds and uses a 1.5 inch handle that contains the motor and battery, allowing the head to lie flat under low furniture.
  • Battery life is about 30 minutes per charge.
  • Cleaning relies on a powered high density microfiber roller with 64,000 filaments per square centimeter and always uses fresh water, not suction.
  • No filter is required, which avoids performance loss from clogging or trapped odors.
  • In a store demo the PencilWash removed a marker mark from wood flooring without leaving a trace.
  • At $349 it is cheaper than the $600 PencilVac and the $770 WashG1 and is positioned as a more capable alternative to a Swiffer
