Robotic Vacuums

Shark Ion Robot 750 vs Roomba 890: Which Cleans Best?

(Last Updated On: November 17, 2017)

Whenever a new robot vacuum from another company comes out, it almost always gets compared with iRobot’s Roomba.  Roombas have set the standards when it comes to robot vacuums and they will somehow be the yardstick that other robot vacuums must measure up to. 

The Shark Ion Robot 750 is a recent entry in the robot vacuum cleaner space while the Roomba 890 is one of the Wi-Fi connected Roombas launched in recent months.  How do these two compare with each other? 

Bottom Line Up Front: Here’s my high level take if you want a quick decision…

Price and design  

The Roomba 890 is available from the iRobot online store for $500 .  Like most Roombas, it has a circular puck look measuring 13.9 inches in diameter and 3.6 inches in height.  This allows the Roomba 890 to cover more of your floors in a single pass, while also fitting under most furniture and cleaning underneath it.

The Shark Ion Robot 750 also has a circular form, but it is shorter and smaller than the Roomba 890, measuring 12.6 inches in diameter and only 2.6 inches in height.  It would take more passes for the Shark Robot 750 to cover the same floor area as the Roomba 890, but it can get under more furniture.

That being said, the designs of both robot vacuums are also quite similar.  The Roomba 890 uses a black and brown color combination, with the singular CLEAN button at the middle.  Meanwhile, the Shark Ion Robot 750 has a silver gray color, with black trims and center and metallic accents.

It has three physical buttons at the top and has a smoother look with silhouettes being used in the design, as opposed to the Roomba 890’s clean and solid look.

Smart and connected 

 Both the Roomba 890 and the Shark Ion Robot 750 connect to your Wi-Fi network and may be accessed using a mobile app.  You can start or pause a cleaning session using their mobile apps, and even create schedules for both robot vacuums.

The mobile apps also give you tips and tricks on how to troubleshoot any problems, along with tips on how to get the most out of your robot vacuum.  Both mobile apps also send notifications from your robot vacuum and allow you to remotely control the robots even when you are away from home. 

Navigation technology 

 The Roomba 890 has optical and acoustic sensors that allow it to find dirtier areas so that it could concentrate on cleaning that part.  These sensors also help the Roomba 890 avoid any obstacles, avoid falling down stairs, and make sure that it does not bump into walls.

The iAdapt navigation helps the Roomba 890 move around the room and ensures full coverage.  The sensors will also detect if the robot vacuum is on a carpet, on a tiled floor, or a hardwood floor, and then automatically adjust its cleaning.

This means that you can be sure that your floors get an efficient clean, no matter what the floor type is. 

The Shark Ion Robot 750 also has similar sensors that guide it to where it should go and help it avoid obstacles.  Relying on its smart sensor technology, the Shark Ion Robot 750 also stays away from stairs while also pinpointing the dirtier parts of your floor.   

Vacuuming and cleaning technology 

 Both robot vacuums follow a three-stage cleaning process.  The Roomba 890’s Aeroforce technology uses the debris extractor and a side brush to agitate, loosen, and sweep dirt, dust, and hair so that the powerful suction could pick them up and send them to the dust bin.

Aeroforce suction is rated to be five times stronger than the suction found in earlier Roombas.  The 890 also uses Aeroforce high-efficiency filter that can trap dust particles 10 microns or bigger, effectively trapping 99% of these airborne particles and keeping them circulating back into the air. 

The Shark Ion Robot 750, meanwhile, has a main brushroll that takes up almost the entire length of its diameter.  The main brushroll measures 11 inches wide and picks up all the hair, dust, and debris that it comes in contact with.  The self-cleaning brush is also less of a hassle to maintain.

In addition to the main brushroll, the robot vacuum also has a pair of side brushes that can take care of the wall edges and corners, effectively making up for the robot vacuum’s round shape.

The Shark Ion Robot 750 uses HEPA filters, which can trap smaller particles that are 0.3 microns in size.  That means that the filter you see inside the Shark Robot is able to trap 99.7% of all airborne dirt and dust. 

One caveat about the Shark Ion Robot 750, however, is that it cannot handle high pile carpets. 

Lithium ion battery 

 Both the Shark Ion Robot 750 and the Roomba 890 have lithium ion batteries that give you a one-hour running time on a single full charge.  Lithium ion batteries are also more durable and longer-lasting.

However, it takes longer to fully charge the Shark Ion Robot 750, needing three hours for a full charge.  The Roomba 890 only needs two hours.   

Speaking of charging, both the Roomba 890 and the Shark Ion Robot 750 are able to find their way back to their charging docks in order to recharge when their battery juice runs low.

Once their batteries are fully charged, you would need to manually resume the cleaning because both robot vacuums do not automatically resume an interrupted cleaning session. 

Spot clean 

 Both robot vacuums offer a spot cleaning mode, wherein they go in a spiral to concentrate on cleaning a small area. 

Voice command 

 Both the Shark Ion Robot 750 and the Roomba 890 support voice command.  If you have an Amazon Alexa speaker or Google Assistant, you can just your robot vacuum to start cleaning or to go back to its charging dock. 

Full bin indicator 

 When the dustbin becomes full, the Roomba 890 will let you know.  This will preclude you from having to guess if you need to empty the dust bin or not.  This feature is not found on the Shark Ion Robot 750, wherein you are expected to empty the dustbin after each cleaning run.

It is very easy to take out the dust bin on the Shark Robot; just detach the bin from the side and throw away the dirt and dust.   

Boundaries 

 Both the Shark Robot 750 and the Roomba 890 have different ways of staying within a particular room or staying out of specific areas.  

The Roomba 890 comes with a dual mode virtual wall barrier that can block off an entire doorway.  You simply turn it on and the IR beams will prevent the Roomba from crossing.

You can also use this device as a virtual wall halo that will protect an area within the room itself.  For instance, if you have a priceless vase or if you have dog food bowls inside the room, you can use the virtual wall halo so that the Roomba 890 does not even get near these objects.

If you have low-clearance furniture where the Roomba 890 always get stuck under, you can also use the dual mode virtual wall barrier to ensure that the robot vacuum no longer cleans underneath it. 

The Shark Ion Robot 750, on the other hand, has the Botboundary strip, which does the same things as the Roomba’s virtual wall device, but looks less elegant and requires more work.

Instead of a device that emits invisible beams, you will rely on a tape-like strip that you would need to cut and stick on the floor in order to keep your robot vacuum from crossing over.

 What should you buy?  The Shark Ion Robot 750 or the Roomba 890? 

 It is interesting to compare these two robot vacuums.  The Roomba 890 comes from the leader in the robot vacuum space, while the Shark Ion Robot 750 comes from the company that is known in the upright vacuum space.  Now for the difficult part, which one should you buy? 

If you are looking to save money and still get a very capable robot vacuum, then get a Shark Ion Robot 750.  Cheaper by $100, this robot vacuum uses a better filter and two side brushes, while offering roughly the same features as the more expensive Roomba 890.

In fact, if you do not have high-pile carpets at home, then you should probably get the Shark Ion Robot 750 here. 

If you are looking for the better-performing robot vacuum, then there is no question about it, go for the Roomba 890.  The Roomba 890 can keep your floors really clean and it has a more reliable cleaning pattern than the Shark Ion Robot 750.
