iRobot Roomba 621 cleans all floor types, this feature comes in handy, since different rooms within a home may have different types of flooring i.e. carpets. If a robot vacuum is stated as being able to clean all floor types, it implies that the robot vacuum is capable to effectively clean flooring materials without much limitations.
A robot vacuum's ability to generate a map of its cleaning area is one of the commonly asked-for features. This map allows the robot to "understand" the layout of the space. This can be used for different situations, e.g.
the iRobot Roomba 621 having the mapping feature can provide efficient cleaning in the mapped-out areas without accessing those that are not. The iRobot Roomba i3 Evo 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 ignoring those that aren't.
iRobot Roomba 621 has an obstacle sensor, such a sensor 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 i3 Evo has an obstacle sensor, obstacle sensors work together to provide the robot vacuum with a better understanding of its environment, enabling it to navigate around furniture, walls, and other objects when cleaning a room and avoiding damage to both the robot and its obstacles. iRobot Roomba 621 has 3 cleaning modes, the number of cleaning modes offered by robot vacuum cleaners can vary widely depending on the design of the robot vacuum.

has the same dustbin capacity as the iRobot Roomba 621
The dustbin capacity can vary widely among robot vacuum models, and the capcity you choose should depend on your cleaning needs and the size of the area you want to clean. Different floor types require a robot vacuum to be at a given ground clearance so as to optimize performance. The iRobot Roomba 621 adjusts its height to match this requirement, for example, it may raise itself slightly when transitioning to a carpet to allow for effective suction, and then lower itself on hard floors to make sure the brushes make good contact.
The iRobot Roomba 621 weighs 4.3kg, robot vacuums are generally designed to be lightweight and compact to easily get around and carrying around. iRobot Roomba i3 Evo, at 6.8kg
weighs more than the iRobot Roomba 621 with a difference of 2.5kg. It's important to consider the weight of the robot vacuum when choosing a model, and that's if you plan to carry it up and down stairs
iRobot Roomba 621 has a width of 340mm, aslo known as its cleaning path width, is the width of the area that the robot vacuum can effectively clean in a single pass.
The width of a robot vacuum is key as it can affect its efficiency and the duration it takes to clean a room
iRobot Roomba i3 Evo, at 133mm
measures less in width than the iRobot Roomba 621 by 207mm. A wider cleaning path can cover more ground in a single pass, shortening the time it takes to clean a room. iRobot Roomba 621's height measures 92mm, here you are considering the measurement from the bottom to its highest point.
Height is a key consideration, especially if you have obstacles with low clearance in your home. The iRobot Roomba i3 Evo, at 36mm
measures less in height than the iRobot Roomba 621 with a difference of 56mm. When selecting a robot vacuum, make sure that the robot vacuum can go 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 a crucial factor that determines how long the vacuum can operate on a single charge. Battery capacity is typically measured in milliampere-hours (mAh), iRobot Roomba 621's battery power is 4,500mAh
iRobot Roomba i3 Evo, at mAh1,800
has less battery power than the iRobot Roomba 621 with a difference of only
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 621 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 621's operating time is 1.5h
iRobot Roomba i3 Evo, at 1.5h
has the same operating time as the iRobot Roomba 621
Always plan cleaning cycles around the vacuum's operating time to maximize efficiency and prevent "incomplete work" between charge intervals. iRobot Roomba 621 has a charge time of 3h, 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. iRobot Roomba i3 Evo, at 2h
spends lesser time charging than the iRobot Roomba 621 with a difference of only 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. The operating power consumption of a robot vacuum cleaner refers to the amount of electrical power the vacuum uses while it's actively cleaning your home. iRobot Roomba 621 has a power consumption of 33W, power is often measured in watts (W) and can vary among different robot vacuum models based on several consuption factors.
An overheating indicator in a robot vacuum serves several important purposes, making it a valuable safety feature. It helps protect the iRobot Roomba 621 from damage by sensing when critical components, such as the motor or battery, are operating at temperatures that could cause harm. This feature is designed to automatically turn off the vacuum after it has completed a cleaning cycle or when certain conditions occur.
