Roomba vs. Shark: The Ultimate Robot Vacuum Face-Off
Robot vacuums have gone from luxury gadgets to time-saving household staples. But with so many brands on the market, one question keeps coming up: Which one is better?
Two of the top names in the space are Roomba (by iRobot) and Shark. Both brands offer Wi-Fi connected robot vacuums with smart features, powerful suction, and automatic dirt disposal. But which one is the better fit for your home?
This guide compares Roomba and Shark across performance, navigation, price, pet-hair handling, and more. Let’s get started!

Quick Overview: Roomba vs. Shark
Brand | Flagship Models | Known For |
---|---|---|
Roomba | j7+, s9+, i3+ EVO | Smart navigation, reliability, auto-empty base |
Shark | AI Ultra, IQ Self-Empty XL | Strong suction, affordability, great for pet owners |
Smart Navigation and Mapping
Roomba:
Roombas use advanced PrecisionVision Navigation and vSLAM mapping technology. Models like the j7+ can identify and avoid cords, pet messes, and clutter. You can set no-go zones and schedule room-specific cleanings. The app learns your habits and suggests optimized cleaning times (how cool is that?).
Shark:
Shark vacuums use IQ or AI navigation systems that create home maps after a few cleanings. Some models include LiDAR-style sensors for better performance in low light. You can also set room-specific schedules through the SharkClean app.
Winner: Roomba
Roomba’s mapping is more precise, and the obstacle detection in models like the j7+ is hard to beat.
Cleaning Power and Performance
Roomba:
Roombas offer strong suction and automatically adjust power on carpeted surfaces. Dual rubber brushes reduce tangles and work well for pet hair.
Shark:
Shark vacuums are known for powerful suction. Many users say Shark cleans more aggressively than Roomba. The brush roll is self-cleaning and ideal for long hair.
Winner: Tie
Roomba has better brush tech. Shark has stronger suction. It depends on your floor type and cleaning needs.
Auto-Empty Dock Comparison
Roomba Clean Base:
Can hold up to 60 days of dirt. Uses sealed disposable bags for hygienic dust control. Quiet and effective.
Shark Base:
Bagless design holds up to 30 days of debris. Saves money on bags but can be messier. Slightly louder and larger than Roomba’s base.
Winner: Roomba
More hygienic and user-friendly. Shark’s bagless system may appeal to users who want to avoid recurring costs.
Pet Hair and Allergies
Roomba:
Dual rubber brushes prevent hair tangles. High-efficiency filters help trap dander and allergens. Great for homes with multiple pets (and long haired gals like my daughter and me).
Shark:
Excellent suction lifts pet hair and dander from both carpets and hardwood. HEPA filters available in newer models.
Winner: Tie
Both are pet-friendly. Shark wins on raw suction, while Roomba offers more allergy-conscious features.
App and Voice Control
Both Roomba and Shark offer strong app features, including scheduling, mapping, cleaning history, and compatibility with Alexa and Google Assistant.
Roomba’s app is a bit more refined and intuitive, especially for managing room zones and cleaning preferences.
Winner: Roomba
