It's advisable to consider the weight of the robot 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, is the width of the area that the robot vacuum can properly 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 space
iRobot Roomba i3, at 337mm
measures less in width than the iRobot Roomba 621 by 3mm. 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 considering 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. iRobot Roomba i3, at 92mm
has the same height as that of iRobot Roomba 621.
When selecting 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 run on a single charge. Battery capacity is measured in milliampere-hours (mAh), iRobot Roomba 621's battery power is 4,500mAh
iRobot Roomba i3, at mAh1,800
has less battery power than the iRobot Roomba 621 by only
A bigger capacity implies longer battery life which can be beneficial if you have a large room 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, at 1.25h
spends less time than the iRobot Roomba 621 by only 0.25h
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, at 5h
charges for longer than the iRobot Roomba 621 with a difference of 2h. 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. 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 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 very important safety feature. It helps protect the iRobot Roomba 621 from damage by sensing when key components, such as the motor or battery, are operating at temperatures that could cause harm.
Auto-off is a feature designed to automatically turn off the vacuum after it has completed an operation or when certain conditions occur. iRobot Roomba 621 has an auto-off feature, which is useful for energy efficiency and battery preservation. Also, iRobot Roomba i3 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.
