iRobot Roomba 621 can clean all floor types, this comes in handy, since different rooms within a home may have various types of flooring i.e. carpets. If a robot vacuum is stated able to clean all types of floors, this means that the robot vacuum is capable to clean a wide range of flooring materials without any significant issues.
Roborock S7 MaxV Ultra can also clean all floor types, which implies that it too is built to be adaptable, giving effective cleaning results on either carpets or hard floors commonly found in homes. The 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 "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 dedicate efficient cleaning in the mapped-out areas keeping out of 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 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 route, 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 better understanding of its surroundings, making it possible to navigate around furniture, walls, and other objects when cleaning a room thus preventing 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 depending on the make and model of the robot vacuum. Roborock S7 MaxV 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, this typically range from 1 year to 2 years, but some higher-end brands may give longer warranties.
The Roborock S7 MaxV Ultra, at 1 year
has the same warranty period as that of iRobot Roomba 621. When considering a robot vacuum cleaner, it's essential to read and understand the warranty terms and conditions, as well as any limitations or exclusions that may apply. iRobot Roomba 621 has washable filters, these are designed to capture dust, dirt, and fine particles during the cleaning process and can be easily removed and cleaned to maintain the vacuum's performance.
Roborock S7 MaxV Ultra comes with washable filters, the advantage of washable filters is that they can be cleaned and reused multiple times, reducing costs of replacing disposable filters, plus it's also good environmentally. The iRobot Roomba 621's dustbin capacity is at 0.5L, dustbin capacity determines how much dust, dirt, and pet hair the vacuum holds before it can be emptied. 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 varies 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. Automatic height adjustment is commonly found in mid-range to high-end robot vacuum models such as the Roborock S7 MaxV Ultra with advanced sensor technology and adaptability.
This feature is essential for maintaining cleaning performance across various floor types, including carpets, rugs, hardwood floors, and tiles. The iRobot Roomba 621 weighs 4.3kg, robot vacuums are commonly designed to be lightweight and compact to easily get around and portability. 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 vacuum when selecting 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, refers to the width of the area that it can properly clean in one go. The width of a robot vacuum is key as it can affect its efficiency and the time it takes to clean a space
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, reducing the time it takes to clean a room.
iRobot Roomba 621'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 low clearance in your home. Roborock S7 MaxV Ultra, at 97mm
measures more in height than the iRobot Roomba 621 with a difference of 5mm.
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
The Roborock S7 MaxV 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 home 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 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 621's operating time is 1.5h
The Roborock S7 MaxV Ultra, at 3h
lasts more than the iRobot Roomba 621 with a difference of 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.
The Roborock S7 MaxV Ultra, at 4h
charges for longer than the iRobot Roomba 621 by 1h. Charge time is an important factor to consider when choosing a robot vacuum, since 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 measured in watts (W) and changes among different robot vacuum models based on several consuption factors. Roborock S7 MaxV Ultra, at 74W
consumes more power than the iRobot Roomba 621 by 41W. Lower power consumption is 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 very important safety feature. It helps protect the iRobot Roomba 621 from damage by detecting when critical components, such as the motor or battery, are operating at temperatures that are dangerous.
