I think that the view of robot vacuum cleaners in the world has changed drastically due to the influence of the Korona-ka that started in 2020. Until now, robot vacuum cleaners have been sold by automatically moving while you are away and cleaning without permission, but you do not know if you can defeat various things or clean them properly in the first place. So, I think there were many people who couldn't take the plunge.

However, as a result of the increased time spent at home in many homes, the rooms become dirty and the opportunities for cleaning increase. In that case, even if you leave it to the robot, if something happens, you can deal with it because you are by your side. As with the author's house, I think that the idea has changed to the idea that robot vacuum cleaners can be used with peace of mind because they are at home rather than away.

In fact, the robot vacuum market is very thriving, with nearly 100 current models currently available in the country. Manufacturers range from long-established stores to general home appliance manufacturers and venture companies. Among them, "ECOVACS" was founded in 1998 as a domestic robot manufacturer in China, and entered the robot vacuum cleaner in 2006, making it a well-established manufacturer in this genre. In Japan, it seems that the window cleaning robot "Winbot" was known before the floor cleaning robot. Currently, it is also the No. 1 brand in cumulative sales of robot vacuum cleaners in 52 countries and regions around the world.

The latest model of the Ecovacs floor cleaning robot "DEEBOT" series and the Amazon-exclusive model is the "DEEBOT N8 +". The price is 74,800 yen. In Ecovacs, when "+" is added at the end, the charging home becomes a model with an automatic garbage collection stand. While many models with garbage collection stands cost more than 100,000 yen, the 70,000 yen range is quite reasonable.

In addition, along with Black Friday, which Amazon will hold from 9:00 on November 26th (Friday) to 23:59 on December 2nd (Thursday), a 30% off sale will be held for 52,360 yen for a limited time. In addition, special coupons will be offered for consumer electronics Watch readers (details of the sale are given at the end of the article).

The body is a twin side brush with a central suction type, and the main brush is in front of the suction port. The suction power is 2,300 Pa, and it has sufficient performance. Thorough cleaning of every corner will remove dust and pet hair from the floor and carpet.

The color of the main body is all white except for the sensor part on the front and the water supply tank part on the back. This time, the automatic garbage collection stand is also unified in the same color, so even if it is installed in the living room, it does not give a heavy impression.

In addition, this machine has an automatic mapping function, which creates a map of the room at the first cleaning and cleans it more efficiently from the next time. For this mapping function, "D-ToF (Direct-Time of Flight)", which has become a hot topic for surveying instruments and automatic driving of vehicles, is adopted. Ecovacs is the first robot vacuum cleaner to be equipped with "D-ToF".

This is a method of irradiating the surroundings with a laser pulse and measuring the delay time until it is reflected from the wall to calculate the distance. Unlike outdoors, indoors have a short distance to the object, and the unit of nanoseconds to picoseconds is measured. One picosecond is only one trillionth of a second, but we measure the delay with that accuracy and map the shape of the room.

A mop pad for wiping water can also be attached to the rear of the bottom. The flooring can be cleaned by suction and by wiping with water at the same time. In addition, with an automatic garbage collection stand, there is no need to dispose of garbage in the dust box inside the main unit.

For the author, who continues to use the old robot vacuum cleaner that he bought a long time ago, which moves randomly and returns, the installation of functions so far at this price is an amazing cost performance.
