This is about giving you your time back, freeing you to focus on things that truly matter.

Self-Emptying with Clean Base Automatic Dirt Disposal - The Pinnacle of Convenience

The i4+ EVO’s self-emptying feature is a game-changer. The Clean Base Automatic Dirt Disposal unit isn’t just a charging dock; it’s an integral part of the cleaning system. When the robot’s dustbin is full, it automatically navigates back to the base. A powerful vacuum within the base then suctions the debris from the robot into an enclosed AllergenLock bag, capable of holding up to 60 days’ worth of dirt.

This system is a marvel of engineering, employing principles of fluid dynamics to create a powerful yet efficient suction mechanism. The sealed nature of the AllergenLock bag ensures that dust and allergens are contained, preventing them from being released back into the air - a crucial consideration for those with allergies or respiratory sensitivities.

The real-world impact of this feature is profound. As Jenni R. enthusiastically shared in her review, “my previously white car-hair covered apartment is NO MORE… the dust comes from outside when i frequently have my windows open for fresh air…so this Roomba- i love it.” This highlights the transformative effect of a truly autonomous cleaning system. It’s not just about clean floors; it’s about a healthier living environment achieved with minimal effort.

Imprint Smart Mapping - The Cartography of Clean

The i4+ EVO’s ability to map your home is a testament to the power of intelligent robotics. Imprint Smart Mapping technology allows the robot to learn the layout of your home, creating a detailed internal map. This isn’t just a static map; it’s a dynamic representation that the robot updates and refines with each cleaning session.

This process involves a sophisticated interplay of sensors, including optical encoders, gyroscopes, and visual localization cameras. These sensors work together to provide the robot with a precise understanding of its position and orientation within your home. The mapping data is then processed by advanced algorithms that enable the robot to plan efficient cleaning paths, navigate around obstacles, and remember specific areas that require more attention.

The benefit of this technology is clear: targeted, efficient cleaning. You can direct the i4+ EVO to clean specific rooms or areas, either on-demand or on a schedule. As C. McGowan’s experience illustrates, the robot’s mapping capabilities improve over time: “The third time I used it…The roomba seemed to spend a lot of time wandering around the house, returned once to empty the bin, and once to recharge. But, it completed every room and did a bang up job of it.” This demonstrates the adaptive nature of the mapping technology, which learns and optimizes its performance with each use.

Powerful 3-Stage Cleaning System - Mastering the Debris

At the core of the i4+ EVO’s cleaning prowess is its robust 3-Stage Cleaning System. This isn’t just about suction; it’s a carefully orchestrated process designed to tackle everything from fine dust particles to larger debris like pet hair and crumbs.

• Stage 1: Edge-Sweeping Brush: A specially designed brush, rotating at an optimal speed, sweeps debris from edges and corners into the path of the main brushes.
• Stage 2: Dual Multi-Surface Rubber Brushes: These brushes are a unique feature of the i4+ EVO. Unlike traditional bristle brushes, they are made of durable rubber that flexes to maintain contact with different floor surfaces, from hardwood to carpets. They work in tandem, one agitating the dirt and the other lifting it into the suction channel. The flexible rubber design, coupled with the counter-rotating motion of the brushes, helps to prevent tangles, particularly with pet hair. This is a significant advantage, as evidenced by user feedback praising the Roomba’s ability to handle pet hair without constant maintenance.
• Stage 3: Power-Lifting Suction: With 10 times the suction power of the Roomba 600 series, this system ensures that loosened debris is effectively pulled into the dustbin. The i4+ EVO employs a high-efficiency motor that generates a powerful airflow, creating a low-pressure zone that draws in dirt and debris.

This multi-stage approach ensures a thorough clean on all floor types. As Luke’s Mom initially observed, “After running the first vacuuming job, I noticed that the Roomba swept up the cat fur, but didn’t suck it up. It rolled the fur into little bundles…I changed the setting to have the Roomba do two passes instead of just one. This helped, but I still needed to use my other vacuum to finish the job.” However, she later updated her review, stating, “Now that it is running on a schedule and has thoroughly cleaned our carpets, it’s able to keep up with the long cat hair; no need to pick up little bundles of fur. I’m very happy with this purchase!” This illustrates how the i4+ EVO adapts to different cleaning challenges, ultimately delivering on its promise of powerful performance.

Precision Cleaning in Neat Rows - The Art of Efficient Navigation

The i4+ EVO doesn’t just wander aimlessly; it cleans with purpose and precision. Utilizing advanced floor tracking sensors, the robot navigates your home in neat, parallel rows, ensuring comprehensive coverage of every area. This systematic approach is not only visually satisfying but also highly efficient.

The robot’s ability to move in straight lines and make precise turns is facilitated by a combination of gyroscope-based navigation and visual localization. The gyroscope helps the robot maintain its orientation, while the visual localization system uses a camera to identify landmarks in the environment, allowing the robot to accurately determine its position within the map.

Moreover, the i4+ EVO intelligently handles recharging. If the battery runs low during a cleaning cycle, the robot automatically returns to its base to recharge. Once sufficiently charged, it resumes cleaning from exactly where it left off, ensuring that no area is missed. The device has a rating of 3.4/5 for battery life, according to the customer reviews.

iRobot OS and App Control - The Brains Behind the Brawn

The i4+ EVO is more than just a collection of hardware; it’s a sophisticated software ecosystem powered by iRobot OS. This operating system is the brain behind the robot’s intelligent features, enabling everything from smart mapping to personalized cleaning schedules.

The accompanying iRobot Home app provides a user-friendly interface for controlling and monitoring the robot. Through the app, you can start or stop cleaning cycles, set schedules, select specific rooms to clean, and even monitor the robot’s progress in real-time.

iRobot OS also incorporates machine learning algorithms that allow the robot to learn from your cleaning habits and preferences. Over time, it can suggest customized cleaning schedules based on your usage patterns, ensuring that your home is cleaned when and how you prefer. It can even suggest extra cleanings during peak allergy or pet shedding seasons. While generally well-received, some users, like denmarkhl, initially encountered connectivity issues: “I had some trouble getting the app to set up since I have 5G internet. It is not compatible but I realized I have 2 WIFI settings-one that is not 5G so was able to set up.” This highlights the importance of ensuring network compatibility for optimal performance. However, after receiving a replacement, they noted, “This one worked correctly right away…It has stayed connected to Wi-Fi and no strange errors.” This underscores the effectiveness of the software when functioning as intended.

Voice Control Integration - Cleaning at the Sound of Your Voice

In an age of smart homes, the i4+ EVO seamlessly integrates with popular voice assistants like Amazon Alexa and Google Assistant. This allows for a truly hands-free cleaning experience. With simple voice commands, you can start, stop, pause, or schedule cleaning sessions without lifting a finger.

This integration is made possible through the use of cloud-based APIs (Application Programming Interfaces) that allow the iRobot platform to communicate with voice assistant platforms. When you issue a voice command, it’s processed by the voice assistant, translated into a command that the iRobot platform understands, and then relayed to the robot.

High-Efficiency Filter - A Breath of Fresh Air

The i4+ EVO doesn’t just clean your floors; it also helps to improve the air quality in your home. The High-Efficiency Filter is designed to trap 99% of cat and dog dander allergens, preventing them from being recirculated into the air during the cleaning process.

This filter utilizes advanced materials and a pleated design to maximize surface area and capture microscopic particles. The principles behind its operation are similar to those used in high-end air purifiers, making the i4+ EVO a valuable tool for allergy sufferers.
