Shark WV200UK vs WV251UK what’s the difference?

The difference between the Shark WV200UK(Single Battery) and WV251UK(Twin Battery) Cordless Handheld Vacuum Cleaners are the Charging Dock design and Battery design.

  • The charging dock designs are different.
    The Shark WV200UK charging dock has two slots for the included Duster Crevice Tool and Multi-Surface Pet Tool.
    Whereas the WV251UK charging base has only one slot for one of the tools, because the second battery also stores on the charging dock, and this takes up the space that is used on the WV200UK to hold the second accessory.
    So, there is no place to store both tools on the charging dock of WV251UK.
    (Both of them come with two accessories.)
  • Battery designs are also different.
    The WV251UK battery has release tabs on the battery
    cap for easy swapping.
    Whereas the WV200UK battery does not have the release tabs, you will need to use coins as suggested in the battery removal and installation instructions to help remove the battery.
    So, the battery design on the WV200UK (single battery version) is not something that you can buy a second battery and use it like the WV251UK (twin battery version).
    But if you still want to do that, yes, it can be done, just requires a bit more work.

Otherwise, they function the same.

These Shark Wandvac lightweight cordless vacuums function similarly to traditional stick & handheld 2-in-1 vacuums, but with a slimmer design.
They are designed for everyday small cleaning jobs.
You can use the hand unit which weighs 2.1 lbs only for quick pickup, or use the hand unit with the wand for longer reach, or connect the floor nozzle to the wand for cleaning hard floors and carpets.

  • Have On/Off button which does not require you to keep holding down. But if you need extra power, you have to hold down the boost button.
  • There is a normal power mode and a Boost button for pressing to get extra suction for tougher messes.
  • They have Shark’s PowerFins brushroll which use silicone fins to replace traditional bristles to deliver continuous contact to floors and deep clean dirt, debris, pet hair & more.
  • They also have self cleaning brushroll design which reduce hair wrapping issues.
    If there is any blockage, you can remove the brushroll cover to access to the roller to clean the brushroll and floor nozzle.
  • Brushroll cannot be turned off when vacuuming.
  • No manual carpet pile adjustment control.
  • They feature Shark’s HyperVelocity accelerated suction power for providing a good cleaning performance.
  • They all come with one lithium ion battery which is detachable. If you want to extend the run time, you can buy an extra battery.
  • One battery runs approximately 8 to 17 minutes. In regular mode, it runs approximately 17 minutes; with the boost button pressed, it runs approximately 8 minutes.
  • Full charge takes approximately 3.5 hours.
  • There’s battery indicator to tell you the battery power level when charging and in use.
  • They use brushless motor like many other stick vacuums on the market.
  • They are bagless, dust cup is small, holds 0.13 quarts, pretty small.
  • The bin has one touch empty design.
  • No HEPA filter. For those who are looking for one with HEPA filtration, this one is not your choice.
  • No LED headlights. If you need one with headlights to help clean low light areas like under bed, please note that these vacuums do not have headlights.
  • Though the floor nozzle is relatively big, the hand unit has the motor inside, so they are top heavy and do not self stand. When you need to take a break or stop to answer the phone or move something, you have to lean the vacuum against something or lay it flat.
  • Wand is straight, length is not adjustable.
  • Come with a Duster Crevice Tool to clean corners, along baseboard edges and other hard to reach tight spots;
    and a Pet Multi-Tool which has stiff bristle brush to clean stuck-on debris, or you can remove the bristle brush to remove stubborn pet hair and large piles of debris from upholstery.
  • Come with a charging base for charging and storage.
    For this somewhat big footprint base, it is strange that it only holds one of the included attachments.
  • You can charge the unit in an upright position or in the side by side position with the charging dock, or charge the hand vacuum without the charging dock.
  • Carry 5-year limited warranty on unit and 2-year limited warranty on battery.
