Features

Automatic Recharge Function

Feature Description

A function that automatically returns to the charging base when the battery is low. The robot vacuum will recharge itself and be ready for the next cleaning session. Useful for hands-free operation and ensures the vacuum is always ready to go.

About This Product

The Roomba i3+ automatically returns to its charging base when the battery is low, ensuring it's always ready for the next cleaning session. This feature provides a seamless, hands-free experience, as the robot will recharge itself and resume cleaning where it left off, making it ideal for consistent upkeep.

Scheduled Cleaning Function

Feature Description

A function that allows you to set specific times and days for the robot vacuum to clean. You can schedule cleaning while you're away from home or asleep. This ensures your floors are cleaned regularly without any effort.

About This Product

The scheduled cleaning function allows you to set specific times and days for the Roomba i3+ to clean, even when you're not home. This ensures your floors are consistently clean without any manual effort, providing a convenient way to maintain a tidy home environment on your own schedule.

Virtual Wall Function

Feature Description

A function that uses either a physical barrier or a virtual boundary (often via app) to prevent the robot vacuum from entering certain areas. Keep the vacuum out of delicate areas, pet feeding zones, or rooms you don't want cleaned. Offers greater control over the cleaning area.

About This Product

The Roomba i3+ supports virtual wall barriers, allowing you to create boundaries to prevent the robot from entering certain areas. This is useful for keeping the vacuum out of delicate zones, pet feeding areas, or rooms you don't want cleaned, providing greater control over the cleaning area and preventing accidental access.

Carpet Boost Function

Feature Description

A function that automatically increases suction power when the robot vacuum detects carpet. This allows for deeper cleaning of carpets and rugs. Ensures effective dirt and debris removal from different floor types.

About This Product

The Roomba i3+ does not have a carpet boost function. Therefore, it does not automatically increase suction power when it detects carpet. While it can transition from hard floors to carpets, it may not provide the same level of deep cleaning on carpets as models with this feature. This could affect its performance on thicker carpets.

Object Detection Function

Feature Description

A function that allows the robot vacuum to detect and avoid obstacles like furniture, shoes, and pet waste. The robot vacuum can navigate around objects more efficiently, reducing the risk of bumping into things and getting stuck. Minimizes pre-cleaning preparation.

About This Product

The Roomba i3+ uses its Dirt Detect Technology and smart navigation to detect and avoid obstacles like furniture. This helps it navigate around objects more efficiently, reducing the risk of bumping into things and getting stuck. This minimizes the need for pre-cleaning preparation, making the cleaning process smoother.

Multi-Floor Mapping Function

Feature Description

A function that allows the robot vacuum to store maps of multiple floors in your home. The robot vacuum will remember the layout of each floor and clean accordingly. Eliminates the need to remap each floor every time you move the vacuum.

About This Product

The Roomba i3+ does not support multi-floor mapping. It can only store one map at a time, meaning it's not ideal for multi-story homes where you want the robot to automatically clean different floors without remapping each time. You would need to manually move the robot and allow it to remap the new floor.

SHOPSTAFF Rating Score

#28

Ranked #28 out of 100 products in Category

3.8

Overall Rating

The Roomba Combo i3+ offers a convenient 2-in-1 vacuuming and mopping solution with self-emptying capabilities. It's a mid-range option with smart mapping, suitable for regular maintenance cleaning. However, it may lack the advanced features and powerful suction of higher-end models, potentially impacting its performance on heavily soiled areas. Expected durability is good, given iRobot's reputation.

Suction Power

3.5

Rating Criteria Explanation

The suction power of a robot vacuum, usually measured in Pascals (Pa), determines how effectively it can pick up dirt, dust, and debris from various floor types. Higher suction power is generally better for carpets and rugs, where dirt can be deeply embedded. However, excessive suction can sometimes be a problem on hard floors, scattering lighter debris instead of collecting it. Look for models with adjustable suction settings to optimize cleaning performance on different surfaces. Insufficient suction will leave dirt behind, while too much can drain the battery quickly and potentially damage delicate flooring.

Rating Comments

While the Roomba i3+ offers a 4-Stage Cleaning System, the actual suction power is not specified. It effectively picks up everyday dirt and debris, but may struggle with deeply embedded dirt or heavier messes on carpets. Consider this limitation if you have thick carpets or high-traffic areas.

Navigation Technology

4.0

Rating Criteria Explanation

Robot vacuums use different navigation technologies to map and clean your home. Older models often use random or bounce navigation, which can be inefficient and result in missed spots. More advanced models utilize systematic navigation, such as LiDAR (Light Detection and Ranging) or visual SLAM (Simultaneous Localization and Mapping). LiDAR uses lasers to create a detailed map of your home, allowing the robot to clean in straight lines and avoid obstacles effectively. Visual SLAM uses cameras to achieve a similar result. Good navigation ensures comprehensive cleaning coverage, avoids repeated cleaning of the same areas, and minimizes bumping into furniture and walls. Smart navigation also enables features like virtual boundaries and zone cleaning.

Rating Comments

The Roomba i3+ utilizes smart mapping to learn your home's layout and clean efficiently in straight lines. It navigates around furniture and obstacles, and allows you to direct it to clean specific rooms. However, it may not be as precise or advanced as LiDAR-based navigation systems.

Battery Life and Coverage Area

3.0

Rating Criteria Explanation

Battery life dictates how long the robot vacuum can operate on a single charge, which directly impacts the area it can clean. Consider the size of your home when choosing a robot vacuum. If you have a large house, opt for a model with a longer runtime. Some models also have a recharge and resume feature, where the robot returns to its charging dock when the battery is low and then resumes cleaning where it left off once charged. Insufficient battery life will mean the robot can't clean your entire home in one go, requiring multiple charging cycles.

Rating Comments

With a battery life of 75 minutes, the Roomba i3+ is suitable for smaller homes or targeted cleaning. It features a recharge and resume function, allowing it to return to the base when low on battery and continue cleaning where it left off, ensuring a complete clean.

Self-Emptying Capability

4.5

Rating Criteria Explanation

Robot vacuums with self-emptying stations automatically empty their dustbins into a larger bin in the base. This significantly reduces the frequency with which you need to manually empty the dustbin, making the robot more convenient to use, especially for allergy sufferers or those with pets. The capacity of the self-emptying bin is also important, as a larger capacity means even less frequent emptying. Without a self-emptying feature, you'll need to empty the dustbin after almost every cleaning cycle, which can be a hassle.

Rating Comments

The self-emptying feature of the Roomba i3+ is a major convenience, allowing it to automatically empty its bin into a Clean Base for up to 60 days. This reduces the frequency of manual emptying and is especially beneficial for allergy sufferers and pet owners.

Mopping Functionality

3.0

Rating Criteria Explanation

Some robot vacuums offer mopping functionality in addition to vacuuming. These models typically have a water tank and a mopping pad that damp-wipes hard floors. The effectiveness of the mopping function varies significantly between models. Some simply drag a damp cloth, while others have more advanced features like adjustable water flow, oscillating mopping pads, or even the ability to lift the mopping pad when encountering carpets. If you have a lot of hard floors, a robot vacuum with good mopping capabilities can save you time and effort. Consider whether the mopping function truly cleans or just spreads water around.

Rating Comments

The Roomba i3+ offers a combo vacuum and mop function, allowing for simultaneous cleaning of hard floors. However, the mopping is a light damp wipe and not a substitute for a dedicated mopping system. It's best suited for light maintenance and removing surface dirt.

Smart Features and App Control

4.0

Rating Criteria Explanation

Many modern robot vacuums come with smart features that can be controlled via a smartphone app. These features can include scheduling cleaning sessions, setting virtual boundaries, creating no-go zones, viewing cleaning maps, adjusting suction power, and receiving notifications. Some models also integrate with voice assistants like Amazon Alexa or Google Assistant, allowing you to control the robot with voice commands. Smart features add convenience and customization to the cleaning process. Without app control, you may be limited to basic on/off functionality and pre-set cleaning modes.

Rating Comments

The iRobot Home App provides control over the Roomba i3+, allowing you to schedule cleaning sessions, customize routines, and integrate with smart home devices like Amazon Echo and Google Home. The app enhances the convenience and customization of the cleaning process.

Manufacturer Reliability and Warranty

4.5

Rating Criteria Explanation

The reliability of the manufacturer and the warranty offered are crucial factors. A reputable manufacturer is more likely to produce a reliable product and provide good customer support. A comprehensive warranty can protect you from unexpected repair costs in case of defects. Before purchasing, research the manufacturer's reputation, read customer reviews, and carefully review the warranty terms. A short warranty period or a manufacturer with a history of poor customer service can be a red flag.

Rating Comments

iRobot is a well-established brand with a reputation for producing reliable robot vacuums. They offer responsive customer service and a standard warranty, providing peace of mind with your purchase. However, some customer reviews mention issues with customer support.

Cost Performance

4.0

Rating Criteria Explanation

Ultimately, the cost-performance ratio is a critical factor. Consider all the features and performance capabilities of the robot vacuum in relation to its price. A more expensive model may offer superior cleaning performance, advanced features, and greater convenience, but it may not be the best value if you don't need all those features. Conversely, a cheaper model may seem like a bargain, but it may lack essential features or have poor cleaning performance, ultimately costing you more in the long run due to the need for manual cleaning or premature replacement. Weigh the pros and cons of each model and choose the one that offers the best balance of features, performance, and price for your specific needs and budget.

Rating Comments

At $280, the Roomba Combo i3+ offers a good balance of features and performance for its price range. The self-emptying capability, smart mapping, and 2-in-1 functionality make it a worthwhile investment for those seeking automated floor cleaning without breaking the bank.
