The width of a robot vacuum is key as it can affect its efficiency and the duration it takes to clean a space
The iRobot Roomba 621, at 340mm
measures more in width than the iRobot Roomba j7 Plus with a difference of 10mm. A wider cleaning path can cover more ground in a single pass, reducing the time it takes to clean a room. iRobot Roomba j7 Plus'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 iRobot Roomba 621, at 92mm
has the same height as that of iRobot Roomba j7 Plus. 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 run on a single charge. Battery capacity is measured in milliampere-hours (mAh), iRobot Roomba j7 Plus's battery power is 2,210mAh
iRobot Roomba 621, at mAh4,500
has more battery power than the iRobot Roomba j7 Plus by
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 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 battery charge before it needs to be recharged.
iRobot Roomba j7 Plus's operating time is 1.25h
iRobot Roomba 621, at 1.5h
lasts more than the iRobot Roomba j7 Plus by 0.25h
Always plan cleaning cycles around the vacuum's operating time to maximize efficiency and prevent "incomplete work" between charge intervals. iRobot Roomba j7 Plus has a charge time of 5h, 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 iRobot Roomba 621, at 3h
spends lesser time charging than the iRobot Roomba j7 Plus with a difference of only 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 feature is designed to automatically turn off the vacuum after it has completed a cleaning cycle or when specific conditions occur. iRobot Roomba j7 Plus has an auto-off feature, which is useful for energy efficiency and battery preservation.
Also, iRobot Roomba 621 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.
