You need the details—the real-life differences that actually affect how clean your home gets.

This article offers an in-depth, side-by-side look at the Shark Ion Robot R75 and the iRobot Roomba E6. We’ll break down 75 key features, specs, and user experience factors, so you can understand which one is right for you. Whether you’re worried about pet hair, battery life, Wi-Fi setup, or just want to know which one will last longer, you’ll find the answers here.

Let’s dive in and see which robot vacuum truly wins in each area.

1. Design And Build Quality

The Shark Ion Robot R75 has a modern, low-profile round body with a mix of glossy and matte plastics. It looks simple but sturdy. The Roomba E6 is also round but uses more matte materials, making fingerprints less visible. The Roomba’s bumper is slightly thicker, giving it a bit more protection during bumps.

2. Dimensions

The Shark R75 measures about 12. 6 inches in diameter and 2. 6 inches tall. The Roomba E6 is 13. 3 inches in diameter and 3. 6 inches tall. This means the Shark can fit under lower furniture that the Roomba cannot.

3. Weight

The Shark weighs 5. 5 pounds, while the Roomba E6 weighs 7. 2 pounds. The lighter Shark is a bit easier to pick up and move if needed.

4. Cleaning System

The Shark uses a two-brush system—a central brush roll and a side brush. The Roomba E6 features the dual multi-surface rubber brushes, which resist tangling and maintain contact with the floor better, especially on carpets.

5. Suction Power

The Roomba E6 provides slightly stronger suction, averaging around 1700 Pa, compared to the Shark’s 1400 Pa. This means the Roomba can pick up heavier debris more effectively.

6. Dustbin Capacity

The Shark holds 0. 45 liters of debris in its dustbin. The Roomba E6 has a 0. 5-liter dustbin, so it can go a little longer between emptying.

7. Filter Type

The Shark uses a HEPA-style filter that can trap dust and allergens. The Roomba E6 uses a high-efficiency filter that captures 99% of pollen, mold, dust mites, and dog and cat allergens.

8. Battery Type

Both robots use lithium-ion batteries, but the Roomba’s battery is slightly larger and built for longer life cycles.

9. Battery Life

The Roomba E6 runs up to 90 minutes per charge, while the Shark Ion R75 averages around 60 minutes per charge.

10. Charging Time

The Shark takes about 3 hours to fully charge. The Roomba E6 needs about 3-4 hours.

11. Charging Dock

Both models come with a compact charging dock. The Roomba’s dock is heavier and less likely to shift around if bumped.

12. Return To Dock

Both robots can automatically return to their dock when the battery is low. However, the Roomba is a bit more consistent at finding its dock, especially in larger spaces.

13. Resume Cleaning

The Roomba E6 does not automatically resume cleaning after charging. The Shark R75 also lacks this feature, so both will need to be restarted manually if their battery runs out mid-cycle.

14. Navigation Technology

The Shark uses random bump navigation with infrared sensors. The Roomba E6 uses iAdapt navigation, which also relies on sensors but tends to create a more efficient cleaning path.

15. Mapping

Neither vacuum creates a real-time map or remembers your home’s layout, but the Roomba’s navigation is a bit smarter at avoiding missed spots.

16. Obstacle Detection

Both models use infrared and mechanical bump sensors to avoid obstacles. The Roomba E6’s sensors are slightly more sensitive, so it’s less likely to get stuck.

17. Cliff Sensors

Both devices have sensors to prevent falls down stairs or off ledges.

18. Cleaning Modes

The Shark Ion R75 offers auto, spot, and edge cleaning. The Roomba E6 has similar modes but also allows you to schedule cleaning by room if you use the app.

24. Scheduling

Both allow you to schedule cleaning times, but the Roomba’s app offers more detailed scheduling options.

25. Carpet Cleaning

The Roomba E6’s dual rubber brushes make it more effective on carpets, pulling up more dirt and hair than the Shark’s bristle brush.

26. Hard Floor Cleaning

Both robots clean hard floors well, but the Shark’s side brush does a slightly better job at pulling debris from edges.

27. Pet Hair Performance

The Roomba E6 excels at picking up pet hair, especially from carpets, thanks to its tangle-free brush design. The Shark is good but can get hair wrapped around its brush roll.

28. Edge Cleaning

The Shark’s side brush sweeps debris from edges into the cleaning path. The Roomba E6’s edge cleaning is less precise.

29. Under Furniture Cleaning

The Shark’s lower height lets it clean under beds, sofas, and cabinets more easily than the taller Roomba E6.

30. Multi-room Cleaning

Both can move from room to room, but without smart mapping, they may miss areas or repeat spots.

31. Spot Cleaning

Both offer a spot cleaning mode for concentrated messes. The Roomba E6’s spot mode covers a slightly larger area.

32. Recharging

Both vacuums can find their dock and recharge automatically when their battery is low.
