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.

Shark IQ vs AI Robot what’s the difference?

Both the Shark IQ and Shark AI robot vacuum series have a few models, you can read the comparison of some of the Shark IQ robots, and AI robots comparison to learn more on each series.

The main difference between the Shark IQ and AI robot is:

images from Shark official site infomercials

  • AI Laser Vision
    The Shark AI robot is a newer series, it features Shark’s most advanced vision module – AI Laser Vision which makes Shark’s IQ Navigation smarter, it helps the robot detect and avoid objects. The better thing is that it supports virtual no-go zones. It can respond to the no-go zones you set up in the app. Meanwhile, the AI robots can still recognize the physical BotBoundary strip.
    To keep the IQ robots from certain spots, you need to use the physical boundary strip, they does not support virtual boundary.
    The AI Laser Vision also enables the AI robot to run properly in low light conditions because the AI Laser Vision is not dependent on ambient lighting.
    Whereas the IQ robots will not navigate correctly in the dark, it cleans but it will not move in a row by row pattern. Because it needs light to know where it’s going. For better cleaning performance and coverage, it is recommended to turn on the lights when running the IQ robots at night or in low light conditions.
    P. S.
    The AI robot will only avoid objects taller than 2.8 inches. Anything lower than this height will not be recognized.
  • #ad: Check AI Robot Price at Amazon
  • Sonic Mopping
    The AI robot includes a vacmop version, including Vacmop RV2000WD and Vacmop Pro RV2001WD, which features sonic mopping that scrubs 100 times per minute. With the mopping module, the robot can vacuum and mop hard floors at the same time. The mopping kit includes a fluid reservoir and a mopping pad. The Vacmop packages also come with a trial size bottle of solution.
    Whereas all the IQ robots are not compatible with the mopping kits.
  • Self Empty
    Though the AI robot is the newer series, it does not support the Self Empty Base which the IQ Self Empty series features. The IQ Self Empty robots come with a self empty base that holds dirt and debris up to 30 days of cleaning. The robot equipped with an Empty & Resume feature that allows the robot to return to its base after 30 minutes of cleaning to empty its dust bin, then resume its cleaning session. This feature can be disabled in the app. Shark recommends to turn this on for high traffic areas and homes with pets.
