iRobot Roomba 621 cleans all floor types, this comes in handy, since different rooms inside a home may have different types of flooring i.e. carpets. When a robot vacuum is advertised as being able to clean all floor types, this implies that the robot vacuum is capable to effectively clean most flooring materials without any significant issues.
Roborock S7 Max Ultra aslo cleans all floor types, this means that it too is designed to be versatile, giving best cleaning performance on either carpets or hard floors commonly found in homes. The 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 keep a record of the layout of the desired space.
This can be used for several purposes, for example the iRobot Roomba 621 having the mapping feature can provide efficient cleaning in the mapped-out areas keeping out of those that are not. Roborock S7 Max Ultra 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 621 has an obstacle sensor, this serves the purpose of detecting and identifying objects in the robot's path, allowing it to navigate around them thus avoiding collisions. Also, the Roborock S7 Max Ultra has this sensor, obstacle sensors work together to provide the robot vacuum with a better understanding of its surroundings, making it possible to navigate around furniture, walls, and other objects when cleaning a room and preventing damage to both the robot and its obstacles. The iRobot Roomba 621 has 3 cleaning modes, the cleaning modes supported by robot vacuum cleaners can vary widely depending on the design of the robot vacuum.
The Roborock S7 Max Ultra, having only 4
has more modes than the iRobot Roomba 621 with a difference of 1
Robot vacuum manufacturers may offer different cleaning modes to provide users with flexibility and adaptability to different cleaning surfaces. The iRobot Roomba 621 has a period of 1 year, warranty periods for robot vacuums typically range from 1 year to 2 years, however some higher-end models may give longer warranty periods.

The iRobot Roomba 621's dustbin capacity is at 0.5L, dustbin capacity indicates how much dust, dirt, and pet hair the robot vacuum can hold before it can be emptied. Roborock S7 Max Ultra, at 0.4L
carries less dirt than the iRobot Roomba 621 by only 0.1L
The dustbin capacity can vary widely among different robot vacuum models, and the size 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.
iRobot Roomba 621 adjusts its height to match this demand, for example, it may raise itself slightly when moving to a carpet to allow for effective suction, and then lower itself on hard floors to ensure 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 Max Ultra with sophiscated 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 generally designed to be lightweight and compact for easy maneuverability and carrying around. The Roborock S7 Max Ultra, at 4.8kg
weighs more than the iRobot Roomba 621 by 0.5kg. It's advisable to take in consideration the weight of the vacuum when choosing 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, refers to the width of the area that it 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
The Roborock S7 Max 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, reducing 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 to its highest point.
Height is a key consideration, especially if you have furniture with low clearance in your home. Roborock S7 Max Ultra, at 96.5mm
measures more in height than the iRobot Roomba 621 by 4.5mm. When selecting a robot vacuum, ensure 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 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 Max Ultra, at mAh5,200
has more battery power than the iRobot Roomba 621 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 with less interruptions to recharge. The operating time of a robot vacuum cleaner refers to the 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
The Roborock S7 Max 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 Max 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 Max Ultra, at 74W
consumes more power than the iRobot Roomba 621 by 41W. Lower power consumption can be more energy-efficient and cost-effective over time, but it may also affect cleaning performance, especially on carpets. An overheating indicator in a robot vacuum serves many key purposes, making it a valuable safety feature.
It helps protect the iRobot Roomba 621 from damage by detecting when key components, such as the motor or battery, are operating at temperatures that are dangerous. Roborock S7 Max Ultra also has an overheating indicator, such an indicator helps mitigate this risk by preventing the robot vacuum from operating under unsafe conditions.
