Roomba 800 series that was high performance in the first place

Speaking of the Rumba 800 series, it is a series that has reigned as a "high end" until the current top model "Rumba 980" (price: about 130,000 yen) is released. I also used it many times in the performance test of the robot vacuum cleaner a few years ago, and it won the number one every time. However, the price was about 80,000 yen for "Rumba 880", which was a courageous price to decide to purchase.

However, the Rumba e5 released this time is 53,870 yen, which is nearly 30,000 yen cheaper. That does not mean that the performance of the 800 series has been reduced, but rather that the cleaning performance and ease of use have improved.

In addition to supporting the first dust box washing with water in Roomba, smartphone cooperation via Wi-Fi is also possible. It is said that iRobot aims to popularize "one unit per family" by lowering the price and making it easier to purchase.

As a basic performance inherited from the Roomba 800 series, it is equipped with a high-speed response process "iAdapt". Dozens of sensors accurately grasp the situation in the room, judge the situation more than 60 times per second, and select and execute the optimum action from more than 40 action patterns. In short, they aren't just running around blindly, they are changing their movements according to the situation, such as the shape and size of the room and how dirty it is.

In addition, "AeroForce 3-stage cleaning system" is also inherited. With dual action brush and power lift suction, even fine dust and carpet hair are removed without missing. By the way, in Roomba e5, the blades of the dual action brush have been improved. By lengthening the blades, it became possible to get closer to the floor material during cleaning, and the suction power was improved.

It also comes with a dual virtual wall to keep Roomba out of places you don't want it to be cleaned.
