A vacuum's ability to generate a map of its cleaning area is one of the commonly asked-for features. The map it creates allows the robot to keep a record of the layout of the space. This can be used for different situations, e.g.
the iRobot Roomba i7 having the mapping feature can dedicate efficient cleaning in the mapped-out areas keeping out of those that are not. iRobot Roomba 621 also has the mapping and navigation feature, navigation defines how the robot vacuum moves around the cleaning area. Mapping and navigation often go hand in hand to help the vacuum navigate to the mapped-out spaces to be cleaned ignoring those that aren't.
iRobot Roomba i7 has an obstacle sensor, this serves the purpose of detecting and identifying obstacles in the robot's way, this allwos it to navigate around them thus avoiding collisions. Also, the iRobot Roomba 621 has this sensor, obstacle sensors work together to provide the robot vacuum with a comprehensive understanding of its environment, enabling it to navigate around furniture, walls, and other objects when cleaning a room thus preventing damage to both the robot and its obstacles. No-go zones is a feature found on many advanced robot vacuum cleaners and the iRobot Roomba i7 is one of them.
These zones are essentially digital boundaries or restricted spaces that you can set up to prevent the robot from accessing specific areas or rooms during its cleaning cycle. Most modern robot vacuum cleaners such as the iRobot Roomba i7 are designed to work with Amazon Alexa, which means that they can be integrated with the Amazon Echo ecosystem and programmed using voice commands. iRobot Roomba i7 is compatible with Google Assistant, allowing you to control it using voice commands through Google Home devices or the Google Assistant app found on smartphones and tablets.

weighs more than the iRobot Roomba i7 with a difference of 1.3kg. It's important to take in consideration the weight of the robot vacuum when getting a model, especially if you plan to carry it up and down stairs
iRobot Roomba i7 has a width of 338mm, aslo known as its cleaning path width, is the width of the area that it can properly clean in one go.
The width of a robot vacuum is important as it can affect its efficiency and the duration it takes to clean a space
iRobot Roomba 621, at 340mm
measures more in width than the iRobot Roomba i7 with a difference of 2mm. A wider cleaning path can cover more ground in a single pass, shortening the time it takes to clean a room. iRobot Roomba i7's height measures 92mm, here you are considering the measure from the bottom of the robot vacuum to its highest point.
Height is a key consideration, especially if you have furniture with limited clearance in your home. iRobot Roomba 621, at 92mm
has the same height as that of iRobot Roomba i7. When choosing a robot vacuum, make sure that the robot vacuum can fit under the furniture and navigate effectively in your living space without getting stuck or causing damage.
The battery power of a robot vacuum cleaner is important as it determines how long the vacuum can operate on a single charge. It is typically measured in milliampere-hours (mAh), iRobot Roomba i7's battery power is 1,800mAh
The iRobot Roomba 621, at mAh4,500
has more battery power than the iRobot Roomba i7 by
A bigger capacity implies longer battery life which can be of advantage if you have a large space or if you prefer the robot vacuum to complete cleaning cycles without frequent interruptions to recharge. The operating time of the iRobot Roomba i7 refers to the time the vacuum can clean continuously on a single battery charge before it needs to return to its charging dock for recharging.
iRobot Roomba i7's operating time is 1.25h
iRobot Roomba 621, at 1.5h
lasts more than the iRobot Roomba i7 by 0.25h
Always plan cleaning cycles around the vacuum's operating time to maximize efficiency and prevent "incomplete work" between charge intervals. iRobot Roomba i7 has a charge time of 2h, the charge time of a robot vacuum cleaner refers to the amount of time it takes for the vacuum's battery to recharge fully after it has been depleted during a cleaning cycle. The iRobot Roomba 621, at 3h
charges for longer than the iRobot Roomba i7 by 1h.
Charge time is an important factor to consider when choosing a robot vacuum, as it determines how long you'll need to wait before the vacuum is ready for its next cleaning cycle. This feature is designed to automatically turn off the vacuum after it has completed an operation or when certain conditions occur. iRobot Roomba i7 has an auto-off feature, which is useful for energy efficiency and battery preservation.
Also, iRobot Roomba 621 has this feature, overall, the auto-off feature in a robot vacuum is a key addition that in a way promotes energy efficiency, prolongs the vacuum's lifespan, enhances safety, and adds convenience to the cleaning operations. iRobot Roomba i7 has a dirt sensor, these are designed to detect the availability of dirt, dust, or debris in the area being cleaned and can be used to adjust the vacuum's cleaning behavior during operation. You may want to consider buying either the iRobot Roomba 621 or iRobot Roomba i7 If you value the ability to automatically adjust the cleaning modes of the robot vacuum based on the level of dirt and debris in your home.
Problem area cleaning enables you to instruct a robot vacuum to focus on cleaning a particular spot in your home, the iRobot Roomba i7 supports this, which can be particularly useful for addressing localized messes or busy areas. The iRobot Roomba 621 also supports this feature, the problem area cleaning feature is a convenient way to address specific area messes or high-traffic areas without running a full cleaning cycle for your entire home. iRobot Roomba i7 supports a smartphone app, through which you can control and monitor the vacuum remotely through your smartphone or tablet.
This feature in robot vacuum cleaners is designed to reduce the likelihood of the robot vacuum becoming stuck while cleaning.
