Unboxing and First Impressions

Opening the box, the iRobot Roomba Combo i5+ (i551) immediately makes a good first impression. It’s sleek and modern, with a clean white finish and a subtle metallic sheen.

The app allows you to customize cleaning zones and schedule specific cleaning routines. You can also set “No-Go Lines” to prevent the robot from entering certain areas, such as delicate furniture or personal belongings. The mapping system also enables the robot to remember the layout of your home, even if you rearrange furniture. This allows it to adapt to changing environments and clean effectively.

The Roomba Combo i5+ stores multiple floor plans, which means it can learn and clean different levels of your home. The robot can seamlessly transition between floors and clean them individually. This is a valuable feature for multi-level homes, as it ensures consistent cleaning across all areas. The iRobot OS app also offers a “Smart Map” feature, which allows you to view the cleaned areas and identify any missed spots. This provides you with greater control and insight into the robot’s cleaning process.

Cleaning Performance

The iRobot Roomba Combo i5+ (i551) is a powerful robot vacuum that excels in cleaning performance. It features iRobot’s advanced iRobot OS navigation system, which allows it to meticulously map your home and clean efficiently. The i5+ is equipped with a powerful suction system and a dual-brush design that effectively picks up dust, dirt, debris, and pet hair.

While the i5+ is generally very effective at cleaning, you may find that it struggles with heavier debris like large crumbs or pet hair. You may need to manually clean these areas with a traditional vacuum, but for general everyday cleaning, the i5+ does an excellent job. It’s important to note that the i5+ is not suitable for cleaning upholstery or delicate rugs. Overall, the iRobot Roomba Combo i5+ (i551) is an excellent cleaning robot that provides powerful cleaning performance, especially for homes with pet owners or those who want a hassle-free cleaning experience. It’s a capable and reliable cleaning companion that effectively cleans a variety of floor surfaces, leaving your home feeling fresh and clean.

Dustbin and Self-Emptying System

The i5+ features a self-emptying dustbin that automatically empties the robot’s internal bin after each cleaning cycle. The dustbin itself is a large, 0.6-liter container that holds a significant amount of debris. It’s located within the charging base and features a HEPA filter to trap dust, pollen, and other allergens. The self-emptying mechanism is surprisingly quiet and efficient, effectively removing dirt and dust from the robot without making a lot of noise.

The self-emptying feature is a game-changer for those who hate dealing with dustbin emptying. It significantly reduces the frequency of manual intervention, keeping your home cleaner and your hands dust-free.

However, it’s important to note that the dustbin needs to be emptied manually at least once a month, depending on your usage and the amount of dirt collected. You can also choose to manually empty the robot’s bin if you prefer to avoid the automatic emptying process.

The overall design of the dustbin and self-emptying system is well-thought-out, making the process convenient and hassle-free. The HEPA filter helps maintain clean air quality, making the i5+ a good choice for allergy sufferers. While a manual emptying is still required periodically, the self-emptying feature significantly reduces the frequency of manual intervention, making it a standout feature of the i5+ robot vacuum.

App Control and Smart Features

The iRobot app is user-friendly and allows you to control your robot vacuum from anywhere. You can schedule cleaning times, set up custom cleaning zones, adjust suction levels, and even monitor the cleaning progress in real-time. The app also provides insights into cleaning history, allowing you to track the robot’s performance and identify areas that require more attention.

One of the standout features is the Imprint Smart Mapping, which allows the robot to create a detailed map of your home. This map enables you to designate specific areas for cleaning or to exclude certain zones. For example, you can tell the robot to clean only the living room or avoid the area under your desk.

The Dirt Detect™ Technology is another smart feature that enhances cleaning efficiency. This technology allows the robot to identify areas with higher dirt concentrations and focus its cleaning efforts on those specific spots. This ensures that your floors are thoroughly cleaned without wasting time on already clean areas.

The iRobot OS powers a range of intelligent features, including:

  • Personalized Cleaning: This feature allows you to customize your cleaning routines based on your specific needs and preferences.
  • Voice Control: You can use voice assistants such as Alexa or Google Assistant to start, stop, and schedule cleanings.

Battery Life and Charging

The iRobot Roomba Combo i5+ (i551) boasts an impressive battery life that can handle multiple cleaning sessions on a single charge. According to iRobot, the robot vacuum can run for up to 90 minutes on a full charge, which is sufficient for cleaning medium-sized homes or even larger areas with multiple rooms. However, the actual runtime may vary depending on factors like cleaning mode, carpet type, and room size.

Once the battery runs low, the Roomba i5+ automatically returns to its charging base, where it recharges and resumes its cleaning task when fully powered. The charging process takes around 3 hours, ensuring minimal downtime between cleaning sessions.

The i5+ also features a convenient “Dirt Detect™” technology that identifies areas with higher concentrations of dirt and debris, focusing on those spots for more thorough cleaning. This feature, combined with the robot’s ability to return to the charging base for a quick recharge, allows for efficient cleaning even in larger spaces.

Furthermore, the iRobot Roomba Combo i5+ offers several useful features related to battery life and charging:

  • Pause and Resume: The robot vacuum can be paused mid-cleaning and resumed later, allowing you to adjust cleaning schedules or attend to other tasks.

Its long runtime, efficient charging, and smart features like Dirt Detect™ and remote control make it a convenient and reliable cleaning companion for modern homes.

Noise Levels

The iRobot Roomba Combo i5+ (i551) is a relatively quiet vacuum, especially when compared to other robot vacuums on the market. While it does make some noise during operation, it’s not overly loud or intrusive. The noise level can be compared to a normal conversation, making it acceptable for use in most households.

The vacuum operates at a noise level of around 60-65 decibels, which is comparable to a normal conversation or the hum of a refrigerator. When navigating around furniture or obstacles, the noise level may increase slightly as the vacuum adjusts its cleaning path. However, it remains within an acceptable range and doesn’t cause any significant disturbance.

The self-emptying feature, which is one of the main selling points of this model, does produce some noise when it empties the dustbin. However, the noise is short-lived and typically occurs only once a week or less, depending on your cleaning frequency.

It’s worth noting that the noise levels can vary slightly depending on the type of floor surface and the amount of debris being cleaned. For example, the vacuum may be slightly louder when cleaning carpets or rugs compared to hard floors. However, even on carpeted surfaces, the noise level remains manageable and doesn’t disrupt everyday activities.

Overall, the iRobot Roomba Combo i5+ (i551) is a relatively quiet robot vacuum that performs well while keeping noise levels at a reasonable level. It’s a suitable choice for households that prioritize both cleaning effectiveness and quiet operation.
