When choosing a robot vacuum, most people want a machine that saves time, works well on different floors, and is easy to use. The Shark Ion Robot R75 and the iRobot Roomba 670 are two models that come up often for people searching for reliable, affordable robot vacuums. Both offer smart features, but they have different strengths and weaknesses. It can be hard to know which one will actually make life easier in your home, especially if you’re new to robot vacuums or English isn’t your first language.

This article will compare the Shark Ion Robot R75 and iRobot Roomba 670 across 75 key factors. You’ll see how they perform, what features really matter, and common mistakes people make when choosing. By the end, you’ll know which model fits your needs best.

1. Design And Build Quality

The Shark Ion Robot R75 has a round, low-profile design, making it easy to slide under furniture. Its body is mostly black with silver highlights. It feels sturdy, but the plastic shell can show scratches over time.

The Roomba 670 is also circular, with a simple black and gray look. Roomba’s plastic shell feels solid, though the bumper can collect marks with heavy use. Both vacuums are similar in size, but the Roomba 670 is a bit heavier.

2. Dimensions

The Shark R75 measures about 12. 6 inches in diameter and 2. 6 inches tall. It’s low enough to fit under most couches and beds.

The Roomba 670 is 13 inches in diameter and 3. 7 inches high. It’s taller, so it may not fit under very low furniture.

3. Weight

The Shark R75 weighs 5. 51 pounds, making it easy to carry between rooms or up stairs.

The Roomba 670 is heavier at 6. 7 pounds. It’s still portable, but less convenient if you need to move it often.

4. Main Brush System

Shark uses a self-cleaning brushroll. This design helps prevent hair from wrapping around the brush, which is helpful if you have pets.

Roomba 670 uses a bristle brush and a rubber beater bar. Hair can wrap around these, so you’ll need to clean it more often.

5. Side Brushes

Both robots have dual side brushes. These help sweep dust and debris from corners and edges into the cleaning path. The side brushes on the Roomba 670 spin faster, which sometimes scatters lighter debris.

6. Suction Power

The Shark R75 offers about 1000 Pa of suction. It can handle dirt and small debris on hard floors and low-pile carpets.

The Roomba 670’s suction is less powerful, around 600 Pa. It works well on hard floors but may miss fine dust or heavier dirt in carpets.

7. Dustbin Capacity

The Shark R75 has a 0. 45-liter dustbin. It’s easy to remove and empty, but fills up quickly in homes with pets or a lot of dust.

The Roomba 670 has a smaller 0. 3-liter bin. You’ll need to empty it more often, especially in larger homes.

8. Filtration System

Shark uses a HEPA-style filter. It catches fine particles, pollen, and some allergens, making it good for allergy sufferers.

Roomba 670 uses a standard filter. It traps common dust, but may let tiny allergens pass through.

9. Cleaning Modes

The Shark R75 offers three cleaning modes: Auto, Spot, and Edge. Auto cleans the whole area, Spot focuses on one dirty spot, and Edge cleans along walls.

Roomba 670 has similar modes, but switching modes can be less intuitive since it relies on physical buttons instead of the app.

10. Smart Navigation

Shark uses random navigation with sensors to avoid obstacles and drops. It bounces around the room, eventually covering the whole floor.

Roomba 670 also uses random navigation. It sometimes cleans the same spot more than once, but will eventually cover the whole area.

11. Obstacle Detection

Both vacuums have infrared sensors to slow down before hitting obstacles. The Shark R75 is slightly more gentle around furniture, while the Roomba 670 can bump a bit harder.

12. Cliff Sensors

Each robot has cliff sensors to avoid stairs or drops. Both are reliable, but dust can cover the sensors over time, so check them regularly.

13. Carpet Performance

On low-pile carpets, the Shark R75 does a better job thanks to higher suction and a self-cleaning brush. The Roomba 670 is good for surface debris but struggles with deep dirt or pet hair.

14. Hard Floor Performance

Both models do well on hard floors. The Shark R75 picks up more fine dust, while the Roomba 670 sometimes leaves small bits near walls.

15. Pet Hair Pickup

Shark’s self-cleaning brush is a big advantage for pet owners. It collects hair without getting tangled. Roomba 670 can pick up pet hair, but you’ll need to cut away hair from the brushes every few days.

16. Noise Level

The Shark R75 runs at about 62 decibels—similar to a quiet conversation. The Roomba 670 is slightly louder at 65 decibels.

17. Battery Life

Shark R75 offers up to 90 minutes on a full charge. Battery life depends on floor type and cleaning mode.

Roomba 670 runs for about 90 minutes as well, but battery life can drop if it cleans carpets for long periods.

18. Charging Time

The Shark R75 takes about 3 hours to fully recharge. The Roomba 670 needs about 2-3 hours for a full charge.

19. Automatic Docking

Both robots return to their charging dock automatically when the battery is low. Sometimes, the Shark R75 has trouble finding the dock in crowded rooms.

20. App Control

The Shark R75 connects to the Shark Clean app. You can start, stop, schedule, and monitor cleaning from your phone.

The Roomba 670 uses the iRobot Home app. It lets you start or schedule cleaning remotely. Both apps require Wi-Fi.

21. Voice Control

Shark R75 supports Amazon Alexa and Google Assistant. You can start or stop cleaning with voice commands.

Roomba 670 also works with Alexa and Google Assistant, but sometimes needs the app to confirm commands.

22. Scheduling

Both robots let you schedule cleanings for different days and times. Shark’s app makes it a bit easier to set custom schedules.

23. Manual Controls

The Shark R75 has buttons on the top for power and spot cleaning. Roomba 670 has a larger button for clean and smaller ones for docking and spot cleaning.

24. Remote Control

The Shark R75 comes with a physical remote control, which is handy if you don’t use the app. The Roomba 670 does not include a remote; you must use the app or onboard buttons.

25. Mapping Features

Neither robot creates a smart map of your home. They both rely on random navigation, so you can’t set “no-go” zones or see a floor plan.

26. Multi-room Cleaning

Both models can move from room to room if doors are open. Without mapping, they may miss spots or clean the same area twice.

27. Edge Cleaning

Shark’s edge mode traces walls and corners, picking up debris. Roomba 670’s side brushes help, but it can leave small bits behind.

28. Spot Cleaning

Both robots have a spot clean mode. Place the robot over a dirty area, and it will clean in a spiral pattern.

29. Dirt Detect Technology

The Roomba 670 features Dirt Detect sensors. It spends more time on areas with extra dirt. The Shark R75 does not have this feature.

30. Bin Full Indicator

Neither the Shark R75 nor the Roomba 670 alerts you when the dustbin is full. You need to check and empty it regularly.

31. Maintenance Alerts

Neither model offers reminders for filter changes or brush cleaning in the app, so set your own schedule to avoid clogs.

32. Battery Replacement

Both robots have replaceable batteries. The process is simple: unscrew the cover and swap the battery. Replacement batteries are available online.

33. Filter Replacement

Shark filters should be changed every 1-2 months, depending on use. Roomba 670 filters also need replacing every 1-2 months.

34. Brush Maintenance

Shark’s self-cleaning brush reduces tangle, but you’ll still need to check it weekly. Roomba 670’s brush requires more frequent cleaning, especially with pets.

35. Wheel Design

Both robots have spring-loaded wheels that climb over small thresholds (up to 0.6 inches). They move smoothly on tile, wood, and low carpet.

36. Handling Cables And Small Objects

Neither vacuum reliably avoids cords or small socks. Remove these before cleaning to prevent jams.

37. Cleaning Under Furniture

The Shark R75’s lower height helps it clean under beds and couches better than the taller Roomba 670.

38. Handling Dark Floors

Roomba 670’s cliff sensors can mistake dark or black rugs for cliffs and avoid them. Shark R75 has fewer issues, but still may avoid very dark surfaces.

39. Climbing Thresholds

Both can climb thresholds up to 0. 6 inches, but may get stuck on taller transitions between rooms.

40. Handling Area Rugs

Light rugs can get pushed or bunched up by both robots. Heavier rugs stay in place, but fringe edges can get caught in brushes.

41. Cleaning Pattern

Both models use a random cleaning pattern. They may overlap areas, which means extra cleaning but less efficiency.

42. Re-start After Pause

If you pause either robot, you must press the button again to resume cleaning. Neither remembers where it left off.

43. Returning To Dock

The Shark R75 sometimes circles the room before finding its dock, especially in complex layouts. Roomba 670 usually finds the dock faster.

44. Dock Size And Placement

Both docks are compact and need to be placed against a wall with space around them. They plug into standard outlets.

45. App Setup Process

Shark’s app setup is straightforward, with step-by-step instructions. Roomba’s app can be confusing for non-English speakers, especially with Wi-Fi setup.

46. Wi-fi Requirements

Both require a 2.4 GHz Wi-Fi network. Neither supports 5 GHz Wi-Fi, which can be a problem if your router only uses newer bands.

47. App Languages

Roomba’s app supports more languages, which is helpful for global users. Shark’s app may have limited language options depending on your region.

48. Physical Durability

Both are sturdy but can show scratches and scuffs from regular use. Roomba’s bumper is more robust for heavy-duty cleaning.

49. Warranty

Shark offers a 1-year limited warranty. Roomba 670 has a 1-year warranty as well. Both cover defects but not accidental damage.

Shark and iRobot have good customer support, though wait times can be long during busy seasons. IRobot’s online resources are more detailed.

51. Accessory Availability

Roomba 670 parts (brushes, batteries, filters) are widely available online. Shark R75 parts are available, but sometimes cost more.

52. Virtual Barriers

Roomba 670 supports Virtual Wall Barriers (sold separately). These keep the robot out of certain rooms or areas. Shark R75 does not support any type of virtual barrier.

53. Firmware Updates

Both can receive firmware updates through the app, adding new features or fixing bugs.

54. Multi-user App Access

You can connect both robots to multiple phones, so more than one person can control them. The process is a bit easier with Roomba.

55. Cleaning Summary Reports

Roomba’s app gives a basic cleaning report (run time, job completed). Shark’s app shows less detail.

56. Integration With Smart Home Systems

Both connect to Alexa and Google Home. They don’t support Apple HomeKit.

57. Support For Multiple Floors

Neither robot remembers maps for different floors. If you move them upstairs or to another apartment, they clean randomly.

58. Upgradability

You cannot add advanced mapping or mopping features to either robot. What you buy is what you get.
