IT168 evaluation in life, you may often encounter such a problem: you spend a lot of time and effort to clean the dust at home, but you finally find it is not clean.
Neato Botvac 75 is an intelligent sweeping robot focusing on deep cleaning. It has a higher positioning and value than Neato XV series, because it has a unique D-shaped appearance patent, unparalleled intelligent path planning technology, equipped with the latest research and development of the fifth-generation ARM high-performance processor, a brand-new 14-version RPS laser navigation technology, and added a unilateral brush to increase the cleaning rate of dead corners.

Botvac 75 is packed in orange and dark green cartons. Even with handles, it is quite heavy to carry by hand.
accessories include a Neato Botvac 75 sweeper, a charging base, a power cord, a manual, a dust box baffle and a virtual wall magnetic strip.
Botvac 75 has a circumference of 321×335×1mm and a net weight of 7.6KG It belongs to the big part of the sweeper. It adopts Neato's patented "D" shape design, and the right-angle treatment on the fuselage perfectly fits the wall corner, which solves the problem that the circular sweeping robot has a low cleaning rate for this kind of dead corner. The shell is made of polymer polycarbonate, which looks ordinary, but after dozens of processes such as cutting, washing and polishing, the mirror-like shell can be kept strong and durable.
inside the green dome is the 214 RPS laser ranging radar. Compared with the Neato XV series laser radar, the photosensitive area is increased by 12%, and the positioning and obstacle avoidance are more accurate.
the device is also equipped with "uMemory coordinate memory algorithm". For example, Botvac 75 unexpectedly stops cleaning at a certain position because of insufficient power, so it will return to the previous position after automatic charging and continue to complete the remaining cleaning work. Therefore, the largest cleaning area of Botvac 75 is also one of the most proud places of Neato, 5 square meters!
the sweeper has a built-in TI PBGA298 ARM processor, a brand-new ARM V7-A architecture, a main frequency of up to 5MHZ, a 65nm process design, double-layer cache technology and dynamic branch prediction technology. For a home sweeper, this is a high-end processor, which brings the ultimate computing performance and makes the sweeper have great positioning, cleaning and scanning capabilities. Compared with XV series, the processing speed is four times stronger, while the power consumption is reduced by 1%.
next to the radar is a 2.4-inch color display screen, which corresponds to four touch keys. The prompts of returning, confirming and selecting up and down are straightforward. Although there is no feedback, the response is quite rapid. The screen will light up automatically after the machine is turned on, and the remaining power and time (which need to be adjusted) will be displayed at the top of the welcome screen. Click the select key to enter the main menu, and mainly set the scheduled cleaning, current time and language.
The only two physical buttons on the fuselage are the fixed-point cleaning button and the wake-up button respectively. The green sign and the orange lights around the buttons are as fresh and energetic as the main color scheme of the sweeper.
The dust box is a triangular transparent box, which optimizes the air intake structure, reduces noise, and can hold up to 7ml of dust. Medical grade HEPA filter paper is installed at the back to prevent leakage and pollution.
the suction port of p>Botvac 75 is also a traditional inverted trapezoid, so it is absolutely no problem to vacuum and other small particles. Next to it is a master switch, which must be turned to "ON" before charging.
let's take a look at the bottom of Botvac 75.
The driving wheel with independent suspension arm has regular tooth pattern on the surface, which has excellent grip, can cross obstacles with a height of 2CM, and can quickly break away from the rope.
Botvac 75*** has three distance sensors, one in front of the roller brush and the other above the side brush, to prevent the sweeper from falling and colliding once the hanging terrain and walls are detected.
dust collection system of this product has a nice name: "αCyclone" cyclone dust collection system, which is equipped with a 45W brushless motor, which can generate a strong suction of 11 Pa and a flapping speed of 72 times per minute, leaving dust nowhere to escape wherever it goes.
Botvac 75 adopts a 27.6CM long rubber-wool brush, which has a double scraping effect on different garbage on the ground, and it can be seen that there is a gap between the film and the bristles and the metal fence, further reducing the possibility of hair entanglement.
There is a row of cooling holes at the bottom, from which noise is emitted. The upper and lower metal contact strips are used to connect the base for charging.
The trunking design on the back of the charging base is particularly considerate, and this 2m-long power cord can be easily coiled into 2-3 turns, saving space.
Cleaning test:
Before the cleaning ability test, Xiaobian mixed a certain amount of corn flour, red beans and oats as the cleaning objects of Botvac 75, and sprinkled them evenly on the smooth tile floor of about 1 square meters. Here, a video was used to test the cleaning ability of Botvac 75.
Neato sweeper has only two cleaning actions: edge cleaning and bow cleaning, and Botvac 75, as a high-end model, is no exception. Nevertheless, the coverage rate is not lower than that of those products equipped with 6-7 kinds of cleaning actions, and it also refuses to leave the garbage behind because of mindless random walking. Botvac 75 does not rigidly follow the fixed route, but automatically plans the best route in the obtained map according to the scanning, judgment and drawing of the terrain. The cleaning route is clear and can be followed, and it can be superimposed on the edge of the last cleaned area every time it turns and walks in a straight line, with the help of unilateral brush and right-angled head to take care of the corner, and the omission rate is close to zero.
the suction of p>Botvac is as high as 11 pa. It relies on a high-speed roller brush with a width of 26.7CM. It dares not neglect a large number of scattered objects, and drives away at full speed, leaving only a clean floor and a few traces of missed sweeping, and the cleaning rate is over 9%. After the final cleaning, thanks to the uMemory coordinate memory algorithm, Botvac 75 began to slow down and shut down the dust collection system, and drove back to the starting point accurately. And if the starting point is the charging base, there is no doubt that Botvac 75 will automatically recharge after cleaning, which is very intelligent.
more than 95% of the ground garbage is completely absorbed by Botvac 75, and temporarily placed in a 7ml dust box. If this garbage is only the average amount cleaned by a 1-square-meter family in one day, Botvac 75 still has enough capacity to complete it in the face of the maximum cleaning area of 5 square meters.
Walking performance test:
Botvac 75 will give priority to walking close to the wall, but it still can't completely avoid the collision for the legs of tables, chairs and low obstacles. Fortunately, it is only a careless touch, which is not a disadvantage compared with focusing on careful coverage and deep cleaning. Every time I drive to the bottom of the sofa, the cover of the ranging radar is stuck because of the lack of height, so Botvac 75 can't move forward. At this time, I have to spend some time navigating the path again, and hesitate for a few seconds before quitting, which is a bit slow.
subsequently, the noise of Botvac 75 was measured to be about 65dB, which was a little higher than the official standard of 6dB. Compared with the Neato XV-21 last evaluated by Xiaobian, the noise of Botvac 75 sounds similar, but the volume is really not as harsh as the former.
Anti-falling test:
Botvac 75 can quickly identify the suspended area, stop in time and move to a safe place to continue, and the anti-falling ability is in place.
automatic recharging test:
Botvac 75 is the same as all Neato sweepers. When we click the button, the sweeper will work automatically, so many times when the machine is running out of power, it will find its own base and charge it. After charging, it will return to the interrupted position to continue, without user intervention, completely freeing its hands. Or choose automatic recharge after being manually suspended by the user in the middle of cleaning.
Botvac 75 uses a single 36mAH Ni-MH battery, and the battery capacity is nearly half less than that of the 64mAH of XV series. However, due to the new ARM V7-A architecture processor, the battery life is improved by 8%. The continuous cleaning time can also exceed 1 minutes, and it takes 9-12 minutes to fill it at a time.
