Shark ION Robotic Vacuum AV751 evaluate: Nice suction, no sense of route | ZDNet

Should you’re looking for expertise that makes life simpler, robotic vacuums and robotic mops must be on the tip of your record. And there are extra inexpensive choices than you assume.

For the previous a number of weeks, I’ve been testing out the Shark ION Robotic Vacuum AV751. It’s a good robotic vacuum, and retains up with my two canines and cat. The Shark ION Robotic Vacuum AV751 is an older mannequin, making it a budget-friendly possibility with name-brand recognition. That stated, whereas it will get the job carried out by way of suction energy and cleansing capacity, there are some notable drawbacks that you could be or might not be deal breakers for you. Right here’s the news.


  • Nice suction energy
  • 120 minute run time
  • Tri-brush system

Don’t Like

  • No mapping capacity
  • Doesn’t at all times discover its method again to the docking station
  • Doesn’t alert when it’s full


Product dimensions

12.4 x 12.6 x 3.54 inches

Merchandise weight

8.23 kilos


1 Lithium ion battery required (included)

Included elements

(1) Shark ION Robotic, (1) charging dock, (2) facet brushes, (1) filter

Every part that you must get the Shark up and working comes bundled within the field, together with the charging dock, filters, and further brushes. The robotic was constructed with your private home in thoughts; it’s sufficiently small to suit underneath most furnishings, however nonetheless giant sufficient to wash adequately with its three brushes.


I’d like to start out by stating the apparent: the Shark ION Robotic Vacuum AV751 doesn’t include any kind of mapping functionality, which means it doesn’t monitor what and the place it has cleaned earlier than. Even when giving it full vary of my open-concept lounge, kitchen, and eating room, there can be instances when the Shark would primarily clear in a single space and name it a day. Realizing this, I ran the robotic each single day to get the utmost cleansing. You probably have an open-concept residence and don’t plan on working the robotic day by day, then the Shark in all probability isn’t for you. 

Alternatively, for any rooms which have doorways, I might simply stick the vacuum in there, shut the door, go away it for 10 minutes, and are available again to fully cleaned flooring. 

The vacuum comes with three buttons for a simplified consumer expertise.

Suction energy

The place this robotic lacks in mapping expertise, it makes up for with its suction energy on tiles, laminate, and rugs. Not solely did I run the vacuum day by day in a home with two canines and a cat, however I additionally examined its suction energy on items of pet food, blades of grass, kitty litter, and a few crushed-up potato chips. It didn’t miss a beat when cleansing; it sucked up all the pieces in its path. 

On high of these particular exams, my flooring appeared spectacular after working the vacuum. It was so environment friendly at cleansing the flooring that I used to be in a position to mop instantly after with out having to fret about any mud or particles left behind.

On my carpet, the Shark ION AV751 cleaned the highest floor properly, however wasn’t as efficient with the bits beneath. Consequently, I ended up resorting to my common vacuum in my bedrooms because it did a greater job at cleansing the strands of canine and cat hair buried within the carpet ground.

To be honest, the Shark isn’t marketed as a pet-friendly vacuum. As an alternative, pet house owners who desire a robotic vacuum for his or her furry animals ought to go for the AV993 IQ mannequin.


The Shark ION AV751 didn’t have any points going between completely different floorings. It transitions properly throughout tiles, carpets, and laminate. Not solely was it sturdy and decided sufficient to drive proper up onto my carpet, however it might typically by chance finds itself climbing up onto the platform of my cat tower. (Once more, the shortage of mapping is in charge right here.) The tower isn’t one thing that I essentially need swept, however I used to be nonetheless impressed by the Shark’s mobility. Naturally, the vacuum barely get caught navigating by way of a house.

And I say barely as a result of there may be one place that the robotic routinely will get caught in, which is on the ground vent of the nook of my eating room. The vacuum is often in a position to get itself out of powerful conditions, however this nook vent particularly is a robotic dying lure. This must be a non-issue if your private home doesn’t have ground vents.

Extra: Finest robotic vacuums cash should purchase

The Shark ION Robotic Vacuum AV751 is concerning the common measurement of robotic vacuums I’ve examined, and does a pleasant job of maneuvering round my home. It matches properly underneath my beds, couches, finish tables, and eating room desk, cleansing a whole lot of the filth and dirt spots that I normally miss.


Shark’s tri-brush system ensures that any filth and particles in its path will likely be picked up.

Stairs and ledges

One characteristic that actually stunned me with this vacuum was the cliff sensors it makes use of to sense and keep away from stairs and ledges. The primary time the robotic approached my stairs, I used to be nervous and stood intently to snag the vacuum simply in case it determined to take a tumble. A lot to my shock, it by no means did. Each time it approached the steps, it might clear proper to the ledge after which flip round. The expertise right here works brilliantly.


Like different Shark robotic vacuums, the AV751 works with the SharkClean app, Alexa, and Google Assistant. The app is consumer pleasant and straightforward to navigate. You can begin and cease your robotic along with scheduling cleansing cycles all inside it.

When scheduling, the app and robotic work seamlessly collectively; the vacuum at all times began promptly on the right time. Simply be sure you have it plugged in and charged earlier than doing so. Alexa and Google Assistant had been additionally straightforward to arrange and use, though I didn’t discover them as handy because the SharkClean app. Oftentimes, I’d have already got the vacuum scheduled to run, so I didn’t want to inform it to start a cleansing job. 

One other factor the Shark ION AV751 struggles with is discovering its method again to the docking station after finishing a cleansing cycle. Every time it completed its job and was too removed from the dock, it might aimlessly drive round in search of the docking station (and wasn’t very profitable). Extra instances than not, I needed to go discover the vacuum, cease it, and station it myself.

This isn’t terribly inconvenient. Should you had been to schedule the vacuum to run whilst you’re at work, nevertheless, there’s a very good likelihood that it might run out of battery looking for the docking station. You’d return to a misplaced, lifeless robotic vacuum. 

Backside line

For $229, I just like the Shark ION AV751 for its suction energy and the way simply it navigates round my home. It isn’t too loud, matches properly beneath my furnishings, and lasts as much as two hours on a single cost. There are some notable drawbacks like the shortage of mapping capabilities and incapability to return to its docking station. However for the value, the compromises could also be value it.
