When choosing a robot vacuum, ensure 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 a crucial factor that determines how long the vacuum can run on a single charge. It is measured in milliampere-hours (mAh), iRobot Roomba 675's battery power is 1,800mAh
The iRobot Roomba 621, at mAh4,500
has more battery power than the iRobot Roomba 675 by
A bigger capacity implies longer battery life which can be of advantage 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 675 refers to the time the vacuum can clean continuously on a single charge before it needs to return to its charging dock for recharging. iRobot Roomba 675's operating time is 1.5h
The iRobot Roomba 621, at 1.5h
has the same operating time as the iRobot Roomba 675
Always plan cleaning cycles around the vacuum's operating time to maximize efficiency and prevent "incomplete work" between charge intervals. iRobot Roomba 675 has a charge time of 2h, 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 621, at 3h
charges for longer than the iRobot Roomba 675 by 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 begins its next cleaning cycle. This is the amount of electrical power the vacuum uses while it's actively cleaning your home.
iRobot Roomba 675 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. iRobot Roomba 621, at 33W
has the same power consumption as that of iRobot Roomba 675. Lower power consumption can be more energy-efficient and cost-effective over time, but it may also affect cleaning performance, especially on carpets.
This feature is designed to automatically turn off the vacuum after it has completed a cleaning cycle or when specific conditions occur. iRobot Roomba 675 has an auto-off feature, which is useful for energy efficiency and battery preservation. Also, iRobot Roomba 621 supports this feature, overall, the auto-off feature in a robot vacuum is a key addition that in a way promotes energy efficiency, prolongs the vacuum's lifespan, enhances safety, and adds convenience to the cleaning process.
iRobot Roomba 675 has a dirt sensor, dirt sensors are designed to detect the availability of dirt, dust, or debris in the area being cleaned and based on their readings adjust the vacuum's cleaning behavior during operation.
