The iRobot Roomba i3 Evo, at mAh1,800
has less battery power than the iRobot Roomba 621 by only
A bigger capacity usually means longer battery life which can be of advantage if you have a large home or if you would like the robot vacuum to complete cleaning cycles without frequent 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 charge before it needs to return to its charging dock for recharging. iRobot Roomba 621's operating time is 1.5h
iRobot Roomba i3 Evo, at 1.5h
has the same operating time as the iRobot Roomba 621
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 iRobot Roomba i3 Evo, at 2h
spends lesser time charging than the iRobot Roomba 621 with a difference of only 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 can vary among different robot vacuum models based on several consuption factors.
