---
If you are trying to decide between the Shark Ion Robot 750 and the Roomba 670, you are not alone. Both are popular robot vacuums that promise to clean your floors with less effort from you. But even though they look similar at first, they have many differences in features, cleaning power, smart functions, and more.
Choosing the right one can make your life easier, while the wrong choice might leave you frustrated. In this article, you will find a clear, honest, and detailed comparison between these two machines. You will also see some common mistakes buyers make, and practical advice for picking the best robot for your home.
Key Features: What Do You Really Get?
When you look at robot vacuums online, it is easy to get lost in the long lists of features. Some sound impressive, but not all are important for daily cleaning. Let’s break down the main features of both the Shark Ion Robot 750 and the Roomba 670, focusing on what truly matters.
Navigation And Sensors
The Roomba 670 uses a simple navigation system called "iAdapt." It moves in a random pattern, bouncing off walls and furniture. It has cliff sensors to stop it from falling down stairs. This system is basic, but reliable for smaller spaces or less cluttered rooms. One downside: it sometimes misses spots or cleans the same area more than once.
The Shark Ion Robot 750 also uses bump-and-go navigation, but with a slight improvement. It has proximity sensors on the sides and front, allowing it to slow down before hitting obstacles. The Shark model also uses a "Smart Sensor Navigation" system that helps it avoid getting stuck under furniture.
However, neither model maps your rooms or remembers layouts, so they can both miss some areas in bigger or crowded rooms.
Non-obvious Insight
Many buyers think robot vacuums "learn" your home right away. But at this price point, they do not. If you want true mapping, you will need to spend more on advanced models.
Cleaning Power And Technology
Roomba 670 uses a three-stage cleaning system. It has a main brush and a side brush. The central brush is a mix of bristles and rubber, which works well on both carpets and hard floors. The side brush pulls dust from edges and corners into the path of the main brush.
Shark Ion Robot 750 also has a brushroll and a side brush. Its brushroll uses a combination of bristles and soft blades. This design works well for picking up pet hair without much tangling, which is a plus if you have pets.
Both models use suction to pick up debris, but the Roomba 670 is known for having slightly stronger suction on carpets. The Shark Ion Robot 750 performs better on hard floors and is quieter during operation.
Non-obvious Insight
If your home has mostly carpets, you may notice a bit more pickup from the Roomba. If you have mostly hard floors or a mix, both do well, but Shark is quieter—a big help if you work from home or have a baby.
Battery Life And Charging
The Roomba 670 offers about 90 minutes of cleaning per charge. When the battery runs low, it returns to the charging dock by itself. However, it does not resume cleaning after charging.
The Shark Ion Robot 750 runs for 60-70 minutes on a full charge. It also returns to its dock, but like the Roomba, it does not automatically resume cleaning where it left off.
Practical Example
If you have a small apartment, either robot can finish in one charge. For larger homes, you may need to restart the robot manually if it runs out of battery before finishing.
Dustbin Capacity
The Roomba 670 has a dustbin capacity of 0. 3 liters. The Shark Ion Robot 750 offers a similar size, also around 0. 3 liters.
This means you will need to empty the dustbin every one or two cleanings, depending on how much dust and pet hair you have.
Pro Tip
Some buyers forget to empty the dustbin often. When it’s full, the robot’s cleaning power drops. If you have pets, you may need to empty after each run.
App And Voice Control
Both robots can connect to Wi-Fi, letting you start, stop, or schedule cleanings from your phone. Roomba uses the iRobot HOME app, which is simple and reliable. Shark uses the SharkClean app, which offers similar functions.
Both models also work with voice assistants like Alexa and Google Assistant. You can say, “Start cleaning,” and the robot will begin.
Real-life Example
If you’re at work and want the floors clean before you get home, you can use the app to start a cleaning run from anywhere.
Maintenance Needs
All robot vacuums need basic care. You will need to empty the dustbin, clean the brushes, and check the wheels for hair or debris.
The Roomba 670 has a brushroll that can tangle with long hair or pet fur. Cleaning it takes a few minutes and you may need to use the cleaning tool provided.
The Shark Ion Robot 750’s brushroll is designed to reduce tangles, making it a bit easier to maintain for pet owners.
Mistake To Avoid
Don’t wait until the robot gets stuck or makes strange noises to clean the brushroll. Set a reminder to check it once a week.

Cleaning Performance: Tests And Real-world Experience
To really see the difference between Shark Ion Robot 750 and Roomba 670, it helps to look at how they perform in everyday homes, not just in the lab.
On Hard Floors
Both vacuums pick up dust, crumbs, and pet hair on hard floors like wood, tile, or laminate. The Shark Ion Robot 750 tends to do better with fine dust because of its soft brushroll. It glides smoothly and is less likely to scatter debris.
The Roomba 670 does well with larger bits, like cereal or dry pet food. Its stronger suction gives it a small edge in picking up heavier debris.
Example
If you have a kitchen with tile or wood, both robots will keep it clean. But if you have a lot of sand or fine dust (common in homes near the beach), the Shark may leave fewer small particles behind.
On Carpets And Rugs
Carpet cleaning is where the Roomba 670 stands out. Its main brush digs into carpet fibers to pull out dust and dirt. It can handle low and medium-pile carpets, but may struggle with thick shag rugs.
The Shark Ion Robot 750 also cleans carpets but is best for low-pile or area rugs. Its brushroll is not as deep-cleaning as the Roomba’s.
Practical Tip
If you have mostly wall-to-wall carpets, Roomba’s technology is more effective. For homes with a mix of rugs and hard floors, either model works.
Edge And Corner Cleaning
Both models use a spinning side brush to sweep dirt away from walls and into the path of the vacuum. In real homes, this means they get most of the dust along baseboards.
Neither robot can reach deep into tight corners, but the Shark’s slightly longer side brush sometimes gets a bit closer.
Experience-based Insight
No robot vacuum is perfect at cleaning corners. You may need to use a hand vacuum or broom for tight spots once a week.
Handling Pet Hair
Pet owners know that fur can be a challenge. Both the Shark and Roomba can pick up pet hair, but the Shark’s brushroll design reduces tangling.
If your pets shed a lot, you will still need to clean the brushroll often. The Roomba’s bristles can trap hair more easily, which may need more frequent maintenance.
Common Mistake
People sometimes expect robot vacuums to replace all cleaning. But for homes with heavy shedding, you still need to do a deeper clean with a regular vacuum now and then.

Smart Features And Usability
Smart features sound exciting, but what do they mean for daily use?
Scheduling And Remote Start
Both robots allow you to set a cleaning schedule in their apps. You can pick the days and times you want them to run.
The Roomba app is simple: pick the time, set the schedule, and you’re done. The Shark app offers more flexibility, letting you set different schedules for different days.
Example
If you work from home on Mondays but are out the rest of the week, you can tell the Shark to clean only when you’re away.
Voice Commands
Both the Roomba 670 and Shark Ion Robot 750 work with Alexa and Google Assistant. You can start or stop cleaning with your voice.
Real-life Scenario
If your hands are full cooking dinner, you can say, “Alexa, ask Roomba to start cleaning,” and the robot will begin.
Notifications And Updates
The Roomba app sends simple alerts, like when a cleaning job is finished or if the robot is stuck. The Shark app does the same.
Both apps let you name your robot, so you can say, “Start cleaning with Sharky,” which can be fun for families.
Pro Tip
Make sure your Wi-Fi is stable where the dock is placed. If the signal is weak, the app may not work reliably.
Manual Controls
Both robots have buttons on top, so you can start cleaning without a phone or voice assistant. This is useful for guests or if your phone battery is dead.

Design And Build Quality
Design is more than just looks. It affects how well the robot can clean, fit under furniture, and avoid getting stuck.
Size And Height
The Shark Ion Robot 750 is about 3 inches tall, while the Roomba 670 is slightly taller at 3. 3 inches. Both can fit under most sofas, beds, and cabinets.
Example
If your furniture has very low clearance, measure before buying. A few millimeters can make the difference between cleaning under your bed or getting stuck.
Wheels And Mobility
Both robots have sturdy wheels that help them cross from hard floors to rugs. The Roomba has a bit more ground clearance, so it can handle thicker door mats or bumps better.
Build Quality
Roomba is known for its strong build. Many Roomba 670 owners report years of trouble-free use.
Shark’s build quality is also solid, but some users report that the bumpers can show scratches more quickly. This does not affect cleaning, but it’s worth noting if you care about looks.

Maintenance And Long-term Use
Robot vacuums are not completely hands-off. Keeping them running well takes a little effort.
Emptying The Dustbin
Both models have easy-to-remove dustbins. You press a button, pull out the bin, and dump it in the trash.
If you have pets or a lot of dust, empty the bin after each use.
Cleaning The Brushes
The Roomba 670 comes with a cleaning tool for its brushroll. Removing hair takes a few minutes.
The Shark Ion Robot 750’s brushroll is easier to remove and clean, especially if you have long hair or pets.
Filter Replacement
Both robots use basic filters to trap dust. Roomba’s filter should be replaced every 2 months. Shark’s filter is washable, so you can rinse it out and reuse it. This can save a little money over time.
Mistake To Avoid
Don’t ignore filter changes. A clogged filter means weaker suction and less cleaning power.
Battery Replacement
The Roomba 670’s battery is user-replaceable. You can buy a new battery easily if the old one wears out.
The Shark Ion Robot 750 also allows battery replacement, but the process is a bit more complicated and may require a screwdriver.
Long-term Insight
Plan for a new battery every 2-3 years if you use your robot often.
