In the field of robot vacuum cleaners, the "2in1" model, which performs suction cleaning and water wiping at the same time, has been highly evaluated in recent years. However, the navigation technology is excellent, and the high-end model with an automatic garbage collector costs more than 100,000 yen. If the robot vacuum cleaner you buy for the first time is "over 100,000 yen", you will still hesitate to buy it.

So, this time, the author, who has tried high-end models of robot vacuum cleaners from various manufacturers, decided to try the "2in1" robot vacuum cleaner "Roborock E5" which can be bought at a relatively reasonable price of 50,000 yen. ..

Roborock E5

57,200 yen (tax included, same below)

SPEC ● Maximum driving time / driving area: 200 minutes / 200m2 ● Charging time: less than 6 hours ● Suction power: 2500Pa ● Maximum operating area for wiping with water: 150m2 ● Steps that can be overcome: 2cm ● Dust container capacity: 640ml ● Water tank capacity : 180ml ● No entry area setting: Barrier tape (sold separately) can be installed ● Water wiping water amount setting: 2 stages ● Smart speaker compatible ● Size / mass: Diameter 350 × H90.5mm / approx. 3.0kg

Even at the 50,000 yen level, the suction power is the same as the top model

The Roborock S7 +, the top model of Roborock, is packed with high-performance features such as the mop vibrating when wiping with water to remove dirt, and the laser sensor to map the room quickly and accurately. However, the price is also quite high at 169,400 yen. Compared to that, the E5 has a simple function, but the price is quite reasonable at 57,200 yen.

While narrowing down the function, the suction power is 2500Pa, which is the same as S7 + / S7, and it strongly removes fine house dust to pet toilet sand. While cleaning with sensors such as W gyroscope and motion tracking, it maps the room and accurately grasps where it has been cleaned and where it has not been cleaned yet. In addition to the smartphone app, you can also operate using the attached remote control.

The procedure for linking with the Mi Home app that can operate Roborock E5 is easy. I just had to follow the instructions of the app and it was pretty easy to understand.

Set the water tank with the mop cloth attached to the main body, and tap the cleaning button on your smartphone to start cleaning. By the way, you can adjust the amount of water to two stages, large and small, for wiping with water, but at first I cleaned with a small amount of water.

Cleaning is done in a U-shape, and finally the outer circumference of the room is cleaned and finished.

Cleaning will proceed in a "U" shape from the beginning. What was characteristic was that when it hits the legs of the table, it did not go around the legs, but after cleaning about 1/4 to half a lap, it returned to area cleaning. I thought that there might be some leftovers, but after cleaning the room, I thoroughly cleaned the outer circumference of the room, and on the way, I cleaned the legs of the table all around. By the way, the E5 has a side brush only on the right side of the main body, so when cleaning the wall, be sure to drive the outer circumference counterclockwise so that the brush always cleans the wall. Despite being an entry model, I was impressed with this perfect setting.

The running speed is unexpectedly fast, and the cleaning finishes faster than I expected because it moves sharply in the room. Still, there is almost no leftover garbage. Also, the rate of splashing the cat litter was fairly low, and there was no litter left on the floor after the vacuum cleaner passed. There is no leftover for dust and house dust. Looking at the mop cloth after cleaning, there is no dust lump, so it is proof that the suction itself is strong enough.

However, the E5 is an entry model only, and the obstacle avoidance performance is at the basic level. It seems difficult to recognize that the legs of the furniture are dark colors such as black and dark brown, and I sometimes bumped into them without slowing down.

Also, if the cords are caught in the suction port, they will not be able to run, so it is necessary to keep them off the floor.

As for wiping with water, if the amount of water is small, the dirt can be removed, but the impression is that it does not have a smooth feel after wiping with a rag. A large amount of water does not make the floor too wet, it dries fairly quickly and makes the floor feel smoother. In addition, since the water tank does not have such a large capacity, it seems better to clean one or two rooms with a large amount of water, and to clean a wider area with a small amount of water.

The suction power is automatically increased on the carpet!The driving noise is not so noisy

This machine is equipped with a function that recognizes the carpet and automatically increases the suction power. At this time, if the mop is attached, the carpet will get wet, so you will only have to remove the water tray and mop cloth and perform suction cleaning. Overcoming steps is up to 2 cm, the same as the upper model.

The driving noise is a little worrisome even if you clean it while turning on the TV. When I used a sound level meter to clean the living room, which is usually about 30 dB, in normal mode (balance mode) and measured the volume, it was around 60 dB from the latter half of the 50 dB range.

When "Silent mode" is turned on in "Suction settings" of the Mi Home app, a new "gentle" mode appears on the suction power selection screen. Cleaning with this will reduce the driving noise by one level. Even the measured value dropped by about 5 dB on average. When cleaning at night, it seems better to use the "friendly" mode.

In addition to adjusting the suction power on the app, you can also reserve a cleaning schedule and check the cleaning history. If you select "remote control", you can manually operate the E5 by using your smartphone instead of the remote control. "Spot cleaning", which cleans only places with a lot of dirt, can also be performed on this operation screen.

Unlike the upper model, it is not possible to automatically identify the room or display the driving route on the map, but it was convenient to be able to select the suction power on the app and easily schedule the cleaning. It is a sufficient function for those who want to use the robot vacuum cleaner simply.

Dust box can be washed with water

Remove the dust box filter and dispose of the dust that has accumulated after cleaning. Dust boxes and filters can be washed with water. Fine particle dust in the dust box, which is difficult to remove with a brush, can be cleaned instantly by rinsing it with water.

On the other hand, since the main brush uses brush hair, it is easy for hair and pet hair to get entangled. However, since the main brush can be removed from the main body with one touch, it was convenient when removing hair with scissors.

The mop cloth for wiping with water can be washed and used repeatedly, and can be easily attached to and detached from the water tray. However, it was a little disappointing that the dark stains remained even after the stains were washed away. If a material that removes dirt entwined with the mop with water is used, it will be easier to clean.

Recommended as the first "2in1" without complaint!

I felt that the Roborock E5 is good enough for people who want to quickly clean the floor in the room with "suction + wiping" cleaning.

As the author, it is highly evaluated that it does the basic suction + wiping with water firmly. With the new Corona, the number of people who care about the cleanliness of the floor has increased due to the increased time spent at home, and if you can keep the floor cleanliness so firmly at an affordable price, it can be said to be a "bargain". prize. I think that it is a model that can be fully recommended for those who want a "2in1" type for the first robot vacuum cleaner, and those who have used suction-only robot vacuum cleaners and want to switch to "2in1" without spending money.
