Picture this: you’ve just come back home after a long and tiring day at work. What do you see when you close the door behind you? A messy home with food, dust, and other items all littered on the carpet and the floor. There’s nothing wrong with living messy but there’s a threshold that makes it unbearable to live in an unkempt and dirty home. The real surprise is finding out that millions of people have also come home to this scenario regularly.
Look, we all live busy lives and no one has the time to clean up around the house when they are working two jobs, trying to study, and taking care of grown-up responsibilities. The pressures of adulthood are very real and if you thought living alone would be life-changing, well, you best account for the cleaning up you’ll need to do as well.
Shark ION ROBOT 700 vs 720 vs 750
Contents
The solution for most people lies in robot vacuum cleaners, and these disc-shaped robots have proven to be game changers. They handle important cleanup tasks like vacuuming and sweeping tiled floors, hardwood floors, and carpets by themselves.

That’s right, don’t have time to clean up around the home? Get a robot vacuum cleaner to do that job for you without any supervision required. They’ve become surprisingly commonplace and you’ll easily find plenty of options in the market. We’re not going to cover all of them, as our focus is going to be on SharkNinja’s 3 most prominent robot vacuum cleaner models.
We’re going to be highlighting all the best features and do a comparative analysis for these three models:
There are subtle differences between the models, but when it comes to cleaning around the home, even the smallest upgrade can be a gamechanger. That’s especially important when it comes to remote controllability, and convenience, so let’s check out how these SharkNinja robots compare.
HEPA Filtration
HEPA filters are the industry standard when it comes to proper filtration. These cutting-edge filters help sieve our particles as tiny as 0.3 microns. So, if you’re living with pets, you’ll thank these HEPA filters as they prevent any microscopic organisms and particles, and pet dander from exiting the bagless dust compartments from these robot vacuum cleaners.
Remote Control
The greatest convenience that a robot vacuum cleaner offers you is the capability of controlling it from a fair distance away. The 700 and 720 robot vacuums come with infrared remote controls that help users set cleaning patterns, schedules, and even have them head back to their charging stations to recharge their batteries when they run low.
When it comes to the 750, there’s a completely different method of controlling the vacuum cleaner. It doesn’t involve using a remote control that is equipped with the robot. When you choose the 720, you can use it with a tablet or smartphone to give it orders for cleaning.
The robot will connect with the Wi-Fi network of your home, and you can give it orders through Amazon Alexa, Google Assistant, and a downloadable smartphone app.
If you’re paranoid about robots conquering mankind and taking over the world, you may want to keep an eye on your robot as it cleans around the home. The 700 and 720 allow you to control them with their remotes when they’re in your sight. But for someone who doesn’t have the time to supervise their robot vacuum, the 750 is the best choice; it gives you a solid connection with the Wi-Fi network in your home so that you can control it from anywhere in the world.

Runtime
There’s not much difference between the runtimes for these robot vacuum cleaners with the 700 being rated as providing a 60-minute runtime. The 720 and 750 both offer a 70-minute runtime before requiring a charge but the 10-minute difference between the models is unlikely to be a gamechanger, considering that none of these robot vacuums have a recharge and resume feature.
Smart Sensor for Surface Adjustment
One of the most important features you must consider in a robot vacuum cleaner is their ability to switch from carpets to smooth surfaces. This means you must look at its ability to adjust suction power, look at the wheels, and the height of the units. All three Shark ION Robot vacuum models come with a smart sensor that will increase suction power automatically when it passes over carpets.

This means if you’ve got a carpeted home, you can rest easy with the knowledge that these robot vacuum cleaners won’t have any problems sucking up dust, debris, crumbs, hair, and other invisible particles from the carpet.
Hair Detangling Technology
If you’re living with pets or are going through a hair fall problem yourself, your robot vacuum cleaner will have a tough task trying to suck in and clean up piles of hair and pet dander. There are going to be two choices for the robot vacuum:
- Fight for its life and detangle the hair
- Give up and clean up something else
The Shark ION ROBOT 700 opts for the first option but if it keeps up picking up hair strands, it’ll affect the roller which won’t manage to pick up dust properly.

If you’re talking about The Shark ION ROBOT 720 and 750 robotic vacuum cleaners, you don’t need to worry about getting your hands dirty in trying to detangle hair. These robot cleaners have their automatic hair detangling technology, which rotates the rollers continuously till the hair is detangled.
You don’t want to be checking on your robot regularly to look for hair tangles. That’s why you would be better off with The Shark ION ROBOT 720 or you could go with the 750.
Bot Boundary Strips
The sensors installed in The Shark ION ROBOT 700, 720, and 750 won’t manage to scan a room and vacuum on a route as it doesn’t have any virtual wall feature. This means if you don’t want your robot vacuum going into other rooms, you’ll need to set up BotBoundary strips that come with the robot kit. However, these strips are a nuisance for most people, especially if they don’t match with your floors.
Final Word
After comparing the three SharkNinja robot vacuum cleaners, the 700, the 720, and the 750 we managed to find more similarities than differences between them. The major difference is that you can connect the 750 with the Wi-Fi network of your home and control the robot through a smartphone app even when you’re not at home. It can also accept orders from Amazon Alexa, and Google Assistant.
The Shark ION ROBOT 700 and 720 are controlled with an infrared remote control but you’ll need to be in the same room as the robot to give it instructions. Another major difference is the hair tangling technology, which is non-existent in the 700. However, when you consider the customer reviews, it’s not been a major problem for many users.
At the end of the day, if you’re looking for greater cleaning convenience around the home with the ease of controlling your robot vacuum from anywhere, the 750 is the best choice.
