iRobot Roomba 621 cleans all floor types, this feature comes in handy, since different rooms within a home may have various types of flooring i.e. carpets. If a robot vacuum is stated as being able to clean all floor types, this implies that the vacuum is designed and equipped to clean flooring materials without much limitations.
Roborock S7 MaxV Ultra aslo cleans all floor types, which implies that it too is designed to be adaptable, providing effective cleaning performance on either hard floors or carpets found in most homes. The vacuum's ability to create a 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.
Mapping and navigation 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 Roborock S7 MaxV Ultra also has the mapping and navigation feature, navigation states 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 spaces to be cleaned leaving out those that aren't. iRobot Roomba 621 has an obstacle sensor, this serves the purpose of detecting and identifying objects in the robot's way, this allwos it to navigate around them thus avoiding collisions. Also, the Roborock S7 MaxV Ultra has this sensor, obstacle sensors work together to provide the robot vacuum with a comprehensive understanding of its surroundings, enabling it to navigate around furniture, walls, and other objects when cleaning a room and avoiding damage to both the robot and its obstacles.
The iRobot Roomba 621 has 3 cleaning modes, the number of cleaning modes offered by robot vacuums varies depending on the design of the robot vacuum. The Roborock S7 MaxV Ultra, having only 4
has more modes than the iRobot Roomba 621 by 1
Robot vacuum manufacturers offer different cleaning modes to provide users with flexibility and adaptability to various cleaning scenarios. iRobot Roomba 621 has a period of 1 year, warranty periods typically range from 1 - 2 years, however some higher-end brands may give longer warranties.

The iRobot Roomba 621's dustbin capacity is at 0.5L, dustbin capacity indicates how much dust, debris, and pet hair the vacuum can hold before it can be emptied. The Roborock S7 MaxV Ultra, at 0.4L
carries less dirt than the iRobot Roomba 621 with a difference of only 0.1L
The dustbin capacity can vary widely among different 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 can adjust its height to match this demand, for example, it may raise itself slightly when moving to a carpet to enable effective suction, and then lower itself on hard floors to make sure the brushes make good contact. Automatic height adjustment is commonly found in mid-range to high-end robot vacuum models such as the Roborock S7 MaxV Ultra with better sensor technology and adaptability.
This feature is essential for maintaining cleaning performance across various floor types, including carpets, rugs, hardwood floors, and tiles. iRobot Roomba 621 weighs 4.3kg, robot vacuums are commonly designed to be lightweight and compact for easy maneuverability and carrying around. Roborock S7 MaxV Ultra, at 4.8kg
weighs more than the iRobot Roomba 621 with a difference of 0.5kg.
It's important to consider the weight of the robot vacuum when selecting a model, especially if you plan to carry it up and down stairs
iRobot Roomba 621 has a width of 340mm, often referred to as its cleaning path width, is the width of the area that the robot vacuum can properly clean in a single pass. The width of a robot vacuum is important as it can affect its efficiency and the duration it takes to clean a room
Roborock S7 MaxV Ultra, at 350mm
measures more in width than the iRobot Roomba 621 by 10mm. 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 looking at the measurement from the bottom of the robot vacuum to its highest point. Height is a key consideration, especially if you have obstacles with limited clearance in your home. The Roborock S7 MaxV Ultra, at 97mm
measures more in height than the iRobot Roomba 621 by 5mm.
When choosing a robot vacuum, ensure 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 621's battery power is 4,500mAh
Roborock S7 MaxV Ultra, at mAh5,200
has more battery power than the iRobot Roomba 621 with a difference of
A bigger capacity usually means longer battery life which can be of advantage if you have a large home or if you prefer the robot vacuum to complete operations without frequent interruptions to recharge.
The operating time of the iRobot Roomba 621 refers to the amount of time the vacuum can clean continuously on a single charge before it needs to be recharged. iRobot Roomba 621's operating time is 1.5h
Roborock S7 MaxV Ultra, at 3h
lasts more than the iRobot Roomba 621 by 1.5h
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.
Roborock S7 MaxV Ultra, at 4h
charges for longer than the iRobot Roomba 621 with a difference of 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 is 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 typically measured in watts (W) and changes among different robot vacuum models based on several consuption factors. The Roborock S7 MaxV Ultra, at 74W
