Roomba i3 vs i5 – Check Which One Is Best & Why?

Why Do I Recommend The Roomba i5?

• The Roomba i5 features Smart Mapping with customizable room cleaning to select and prioritize specific rooms during cleaning, while the Roomba i3 uses standard navigation without the ability to save or label rooms.
• Roomba i5 includes Keep-Out Zones to prevent the robot from entering restricted areas for better control and safety, whereas the Roomba i3 lacks zone-based cleaning options.
• It comes with Carpet Boost technology to automatically increase suction on high-pile carpets for deeper cleaning, while the Roomba i3 maintains a single suction mode across all surfaces.
• The Roomba i5 supports Siri, Alexa, and Google Assistant for wider voice compatibility and smart home integration, whereas the Roomba i3 supports only Alexa and Google Assistant.
• Roomba i5 features iRobot OS 3.0 to deliver improved learning-based cleaning recommendations and smarter scheduling, while the Roomba i3 uses an earlier version with fewer adaptive features.
• It has enhanced edge-cleaning algorithms to better detect and clean corners and wall edges, while the Roomba i3 relies on a simpler single-sweep edge brush system.
• The Roomba i5 includes multi-map storage to remember layouts for multiple floors or rooms, whereas the Roomba i3 lacks internal memory for map saving.
• Roomba i5 supports customizable cleaning preferences per room for adjusting suction power and passes, while the Roomba i3 performs uniform cleaning without user-defined settings.

Maybe the Roomba i3 can make you comfortable because it’s a little bit cheaper than the Roomba i5. But you have to compromise all the above-mentioned features. Now the Decision is Yours. I hope it was helpful to choose the right one.

What Common Both Can Do?

• Dual Multi-Surface Rubber Brushes: Both Roomba i5 and i3 use dual multi-surface rubber brushes that stay in constant contact with different floor types. This ensures efficient pickup of debris and pet hair across carpets and hard floors.
• Dirt Detect Technology: Each model includes Dirt Detect sensors that recognize dirtier areas and automatically perform extra passes. This feature improves cleaning performance on high-traffic zones.
• Automatic Recharge & Resume: Both models automatically return to the dock when their battery runs low and resume cleaning once charged. This allows uninterrupted cleaning cycles for larger areas.
• Wi-Fi Connectivity: Both robots connect to Wi-Fi, allowing users to control them remotely via smartphone or voice assistants. This ensures convenience and full access to smart features.
• Voice Control (Alexa/Google): Both the Roomba i5 and i3 work with Amazon Alexa and Google Assistant for hands-free operation. Users can start, stop, or dock their robot using simple voice commands.
• Compatible with Clean Base: Both Roomba i5 and i3 are compatible with the Clean Base Auto-Empty Station. This adds convenience by automatically emptying the bin after each cleaning.
• 3-Stage Cleaning System: Both share iRobot’s signature 3-stage cleaning process — agitation, brushing, and suction. This design efficiently removes dust, dirt, and debris from all surfaces.
• Edge-Sweeping Brush: Each includes a side edge-sweeping brush designed to capture debris along walls and corners. This ensures no dirt is left at room edges.
• High-Efficiency Filter: Both come with high-efficiency filters that capture up to 99% of dust and allergens. This makes them suitable for homes with pets or allergy concerns.
• Rechargeable Lithium-Ion Battery: Both models use lithium-ion batteries that provide long runtime and maintain consistent suction throughout each cleaning cycle.
• Works on Multiple Floor Types: Each unit automatically transitions between carpets, rugs, and hard floors. This versatility allows cleaning throughout different home environments.
• Cleaning Recommendations: Both robots use iRobot OS to suggest personalized cleaning schedules based on habits and seasons, such as allergy or shedding seasons.
• Dirt Bin Washable: The dustbin of both Roomba i5 and i3 can be washed under running water. This simplifies maintenance and keeps the vacuum hygienic.
• Software Updates (iRobot OS): Both receive over-the-air software updates through iRobot OS, which adds new features and improves performance over time.
