The robot vacuum's ability to generate a digital map of its cleaning area is one of the commonly asked-for features. The map it creates allows the robot to "understand" the layout of the desired space. This can be used for several purposes, e.g.
the iRobot Roomba i7 having the mapping feature can provide 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 move to the mapped-out areas to be cleaned leaving out those that aren't.
iRobot Roomba i7 has an obstacle sensor, such a sensor serves the purpose of detecting and identifying objects in the robot's way, allowing it to navigate around them and avoid collisions. Also, the iRobot Roomba 621 has an obstacle sensor, obstacle sensors work together to provide the robot vacuum with a better understanding of its environment, making it possible to navigate around furniture, walls, and other objects when cleaning a room and avoiding damage to both the robot and its obstacles. No-go zones is a feature found on many advanced robot vacuum cleaners and iRobot Roomba i7 supports this feature.
These zones are essentially digital boundaries or restricted areas that you can set up preventing the robot from entering specific areas or rooms during its cleaning cycle. Most modern robot vacuum cleaners such as the iRobot Roomba i7 are built to work with Amazon Alexa, which implies that they can be added to the Amazon Echo ecosystem and controlled using voice commands. iRobot Roomba i7 is compatible with Google Assistant, enabling you to control it using voice commands through Google Home devices or the Google Assistant app found on smartphones and tablets.

iRobot Roomba i7 has a width of 338mm, often referred to as its cleaning path width, is the width of the area that the robot vacuum can properly clean in one go.
The width of a robot vacuum is key as it can affect its efficiency and the duration it takes to clean a space
The 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 looking at the measure from the bottom to its highest point.
Height is an important 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. Battery capacity 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 usually means longer battery life which can be beneficial if you have a large home or if you would like the robot vacuum to complete operations without frequent interruptions to recharge. The operating time of the iRobot Roomba i7 refers to the amount of 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 with a difference of 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 begins its next cleaning cycle. Auto-off is a feature designed to automatically turn off the vacuum after it has completed a cleaning cycle 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 valuable 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, dirt sensors are designed to detect the concentration of dirt, dust, or debris in the area being cleaned and based on their readings adjust the vacuum's cleaning behavior during cleaning cycle. You may want to consider buying either the iRobot Roomba 621 or iRobot Roomba i7 If you prefer the ability to automatically adjust the cleaning modes of the robot vacuum based on the level of dirt and debris in your space.
