アイロボッ ルンバ i7 対 アイロボッ ルンバ i4

Roomba i4 vs i7: 900 vs 1800 Suction Power

Assuredly, looking at the Roomba i4 vs i7 vacuum cleaning robots, we see that the i7 has superior suction power compared to the i4. Both robots are functional and offer advanced navigation and mapping technologies. The i7 robot has a large dustbin that can hold more debris than the i4 robot with a smaller dustbin. The i7 model, however, has more sophisticated functions than the i4 variant. The latter, however, is a more cost-effective vacuum cleaner with longer battery life.

Suction and dustbin capacity

A review of i4 and i7 robot cleaners reveals they have different suction powers, although the first model is a high-performance vacuum robot with a suction power of 900 Pa. The second model, in comparison, has a robust cleaning mechanism with an 1800 Pa suction power. The Roomba i4 is designed for cleaning small or medium-sized rooms and has a 0.4-liter dustbin capacity. The difference between i4 and i7 Roomba models differ in that the Roomba i7 has a 0.5-liter dustbin and a clean base automated dirt disposal unit while the Roomba i4 does not. The clean base unit has an extra 1.3-liter bin capacity for a cleaner robot that is more automatic.

Using area

Comparing the area covered by the iRobot Roomba i7 vs i4, I observed that the i4 robot has a cleaning area of 2100 square feet while the i7 robot has a cleaning area of 2000 square feet. The Roomba i4 has more cleaning area in a single cleaning cycle thanks to its long battery life of 100 minutes compared to the i7, which has a battery life of 74 minutes. It features dirt detection technology to avoid obstacles and navigate your home effectively. Conversely, the i7 robot sports the iRobot's iAdapt 3.0 navigation technology and an advanced imprint smart mapping that creates a personalized map of areas and rooms in your home and allows you to clean them whenever you want. The Roomba i7 vs i4 offers Wi-Fi connectivity that enables you to clean your home remotely using the iRobot Home app, schedule cleaning sessions, and read cleaning reports from the iRobot cleaners. Both robots also offer voice control using Alexa or Google Assistant.

Noise level

Admittedly, the iRobot i4 vs i7 vacuum cleaners are efficient robots with noise levels of 65.3 and 63.9 decibels, respectively, while its competitor has a noise level of 63.9 decibels. The low noise level of both robots makes them suitable for homes where students and working-class individuals live, as they won't cause distractions nor disrupt conversations. Yet, the noise levels of the i4 versus the i7 Roomba robots may vary depending on their operation mode and the surface they clean due to increased suction power. Also, if you have sensitive hearing, you might find these robots' noise levels too loud.

Carpet cleaning

Comparing the i4 vs i7 Roomba robots' carpet cleaning abilities reveals that both robots can clean hard surfaces and carpets, but the Roomba i7 is more suited to doing so because of its potent suction and sophisticated functions. Both robot vacuums have two multi-surface rubber brushes with dual changeable bristles that can be adjusted to clean various carpet and floor types as well as debris, dirt, and hair. However, the high-efficiency filters on the i4 and i7 robotic cleaners collect 99% of pollen, dust, and tiny pollutants as small as 10 microns. While cleaning your home, the Roomba i4 employs audio and visual sensors to identify walls, furniture, and other items in its route. Moreover, the Roomba i7 sports a camera system that allows the robot to navigate and create a detailed map and floor plans of your home for systematic and efficient cleaning. So, while the i4 tends to clean an area twice, the i7 remembers where it has already been cleaned.
