Robotic Vacuums

The Ultimate Shark Ion Robot 750 Review You’ll Love

(Last Updated On: November 8, 2017)

Shark comes from a small company that first offered home care products such as cleaning solutions and small appliances.  Aside from robot vacuums, the company also offers garment care products, steam mops, and upright vacuums.

The Shark Ion Robot 750 is the company’s answer to Wi-Fi connected robot vacuums that do not break the bank.  How does it fare?

Design

The Shark Robot 750 measures 12.6 inches in diameter and is only 2.6 inches high.  It is both smaller and shorter than a typical Roomba model, which means that it could get into narrower spaces and could clean under more furniture.

Smart and connected

The Shark Ion Robot 750 connects to your Wi-Fi network so that you could control it using the Shark Ion Robot mobile app.

The mobile app allows you to create cleaning schedules for the robot vacuum, and enables the robot vacuum to start cleaning remotely even when you are not home.  And if you have a Google Home Assistant or an Amazon Alexa speaker, you can also use voice commands to tell the robot vacuum to start cleaning.

While the robot vacuum itself has lights that go on when it encounters an error, it can be a bit too confusing to remember what each light means.

For instance, when the DOCK and the SPOT lights are flashing alternately, it means that one of the side brushes is stuck, but if these two lights are flashing together, it means that there is a problem with the brushroll.

Thankfully, you do not have to remember error codes and what each light or a combination of flashing lights means.  You can just consult the mobile app, which will tell you what’s wrong.  On top of alerting you of possible errors, it can also show you how to correct what’s wrong.

Cleaning technology

The Shark Ion Robot 750 uses a main brushroll, which can efficiently agitate and capture hair, dander, dust, dirt, and other unwanted particles.  The brushroll does a good job of keeping your floors – and itself – clean.

Yes, it is self-cleaning, allowing you to spend less time maintaining your robot vacuum because the brushroll can untangle hair, strings, and just about anything that can get tangled in it.

The Ion Robot 750 also has two side brushes that help clean the floor edges more thoroughly.  The Shark Ion Robot 750 has two main cleaning modes.  There’s the default mode, which it uses when it starts cleaning, whether manually, via the mobile app, or according to schedule.

Then you have the spot cleaning mode, which you can use if you want the robot vacuum to concentrate on a smaller area in a spiral pattern.  Spot mode is very useful in cleaning areas that are dirtier.

Navigation technology

The Shark Ion Robot 750 relies on sensors to find its way around the room and to avoid bumping into furniture and walls.  These sensors also prevent it from falling down stairs and elevations.

The battery

The Shark Ion Robot 750 uses a lithium ion battery that delivers at least an hour of cleaning.  When the battery runs low, the robot vacuum will stop cleaning and head back to the charging dock.  Recharging the battery can take up to three hours.

What you would love about the Shark Ion Robot 750

The side brushes on the Shark Ion Robot 750 need to be replaced in time.  The good news is that the manufacturer has included two extra side brushes so you do not have to worry about the first replacement.

Shark also made it a point to price its accessories low.  A full replenishment kit is only $35 (check here) and that already includes a HEPA filter, a cleaning tool, four side brushes, and one brushroll.

You can easily keep the robot vacuum inside one room, or keep it from entering a specific area.  Just use the BotBoundary strips to block off the “restricted” area and it will keep the robot vacuum from crossing there.  The robot vacuum also uses audio alerts so that you can find it if it gets stuck somewhere.

What could be better

The Shark Ion Robot 750 is not meant to replace your upright vacuum.  Instead, it aims to keep the floors clean without having to use your upright vacuum too much.  Even with its smart navigation technology, Shark does not really guarantee that its robot vacuum will be able to clean the entire area thoroughly.

It does, however, follow a slightly different cleaning pattern the next time it cleans.  In short, it may not be able to clean your entire floor today, but with daily use, it should be able to keep your floors spotless.

The Shark Ion Robot 750 comes with 9 feet of BotBoundary strips, and that is quite a lot.  But it does seem like you are going to need it.

The sensors it uses to find its way around your room may not be smart enough to prevent the robot from getting into furniture with low clearances, so you would really need the BotBoundary strips to keep it from getting stuck again and again.

The Shark Ion Robot 750 might also have a difficult time cleaning your high-pile carpets.  You can use the BotBoundary strip to block off the carpets.

The Shark Ion Robot 750 can take a lot of prepping.  In addition to making sure that you have blocked off any low clearance furniture with the BotBoundary Strip and that it does not go over high pile carpeting, you also need to make sure that power cords are safely hidden away.

Lastly, it also needs a considerable amount of time for maintenance.  For instance, you need to empty the dust bin after each use, and you need to check and clean the main brushroll, side brushes, dust bin filter, and front caster wheel every week.

You also need to replace the dust bin filter every two months, the front caster wheel every year, the main brush roll at least every six months, and the side brushes when they are visibly worn.

What’s in the box?

Each package of the Shark Ion Robot 750 includes:

  • The Shark Ion 750 robot vacuum
  • 2 side brushes
  • HEPA filter
  • Lithium-ion battery
  • Charging dock
  • 9 feet BotBoundary Strip
  • 2 BotBoundary connectors
  • Cleaning tool

An Alternative to the Shark Ion Robot 750

Looking at the specs of the Shark Ion Robot 750, you cannot help but draw comparisons with the Roomba 690.

This is especially true if you look at the features both offer, such as the auto recharging, manual docking, Wi-Fi connectivity, compatibility with Amazon Alexa and Google Home, and the lithium ion battery that delivers an hour of running time.

Furthermore, both robot vacuums have roughly similar prices:  the Shark Ion Robot 750 sells for $350 (check here for the latest price), while the Roomba 690 sells for $375 (check here for the latest price).

With only a $25 difference, the Shark Ion Robot 750 and the Roomba 690 both make use of a three-stage cleaning system: side brushes, a main brush, and a powerful suction.  The Shark Ion Robot 750, however, makes use of two side brushes compared to the Roomba’s singular side brush.

The Shark Ion Robot 750 also wins with its HEPA filter, which blocks smaller particles compared to the Roomba 690’s Aerovac Filter.  This means that the Shark Ion Robot 750 is able to trap more dust inside its dustbin than the Roomba 690.

Another area where the Shark Robot wins is the self-cleaning main brushroll, which will ensure that the robot vacuum stays efficient in cleaning without you having to clean the brush that often.

When it comes to looks, both robot vacuums have a circular form, but aside from the smaller footprint of the Shark Ion Robot 750, it also has a more futuristic design than the Roomba 690.

However, the Roomba 690 has been proven to efficiently clean hardwood floors, tiled floors, and carpeted floors.  The Shark Ion Robot 750 was not made for carpeted floors, especially those high pile carpets.

Controlling where the Shark Ion Robot 750 goes also involves the BotBoundary strips, which can look awful on your floors.  The Roomba 690, on the other hand, uses dual mode virtual wall barriers, which use IR beams to do the same function.

These dual mode virtual wall barriers are much easier to set up and you do not have unsightly strips littering your floor.

Lastly, it would seem that the Shark Ion Robot 750 is more random than the Roomba 690.  Shark has been pretty upfront about its robot vacuum’s limitation in that it would not be able to cover bigger floor areas in one go, and that its cleaning pattern changes from one run to another.

Meanwhile, Roomba’s cleaning path is well-tested and it covers as much as your floors as it can.

Final say

The Shark Ion Robot 750 is a capable robot vacuum that is perfect for hardwood and tiled floors.  It is designed to keep your floors clean in between sessions with the upright vacuum.  However, it is not meant to replace your upright vacuum.

Already, the company behind the robot vacuum has shown that it spent a lot of time coming up with its mobile app.  The Shark app not only allows you to schedule cleaning times and operates your robot vacuum even remotely, but it also allows you to troubleshoot errors easily.

The compatibility with Amazon Alexa and Google Home is also a definite plus.

If you do not have carpeted floors and you do not mind spending time to maintain your robot vacuum, you should really consider getting a Shark Ion Robot 750.
