Yeedi K650: An affordable robot vacuum cleaner from AliExpress with wet cleaning.

In the fall of 2020, a rather interesting robot vacuum cleaner appeared on AliExpress, priced between $110 and $130 (up to $175). The model is called the Yeedi K650, but is also known as the Yeedi K651G, though there's no difference between the two. The manufacturer claims the robot has excellent spatial orientation thanks to its gyroscope, is suitable for both dry and wet cleaning, and is equipped with a powerful motor (suction power up to 2000 Pa). Let's explore the Yeedi K650's other features and functions, and most importantly, how it performs at its core function, given its low price. Let's get started!

Equipment

The robot itself is packaged in a branded cardboard box. Let's take a look at what's included in the manufacturer's package.

There's a charging base, but it doesn't have a cord storage compartment. A power adapter is included for connecting the base to a power outlet. The user manual is translated into several languages, including Russian. This is a big plus, considering the robot vacuum is made in China. The kit also includes a wet cleaning nozzle with a pre-installed microfiber cloth, a set of 5 disposable cloths, a replacement center brush, and a spare filter.

Overall, this is a good package for the budget segment. It's missing spare side brushes, but that's not a major issue.

Appearance

Now let's take a look at the robot vacuum cleaner itself. It's white, with a tempered glass top. The box itself had a QR code on the top of the robot for downloading and installing the mobile app; I later removed it to preserve the appearance.

In the center is a single, illuminated Start/Pause button, and next to it is a robot status indicator.

A soft-touch mechanical bumper is installed at the front. It's worth noting that the robot navigates using an internal gyroscope, allowing it to move in a serpentine motion, which is a plus. The bumper has two rubberized strips that further protect furniture from damage.

On the side we see a button for turning on and off the power, as well as a button for resetting the Wi-Fi connection.

The combined water and dirt tank is removable from the rear. The dust bin holds up to 400 ml of dirt, and the water tank holds 300 ml. They are detachable for easy maintenance.

At the top, you'll see a brush attached for cleaning the central brush and dust container. The container is equipped with a shutter to prevent debris from falling out when removed. It features a triple filtration system consisting of a mesh, foam, and pleated filter. The manufacturer specifies the filter as a HEPA filter.

The water tank has a pump for electronically controlling the water flow, a big plus for a budget-friendly device. On the bottom, I see four holes for feeding water to the cleaning cloth. The cleaning cloth, by the way, attaches to the nozzle in an interesting way. Not only is it secured with Velcro, but it also has elastic bands on both sides to ensure it doesn't slip off while the robot is moving.

Let's take a look at the robot's underside. It has two side brushes, three-beam, and quick-release. The mounting points are color-coded. There are four fall protection sensors. The central brush is equipped with a hair-tangle protection system. The robot comes standard with a silicone turbo brush, which reduces the likelihood of pet hair and fur getting tangled. The brush can be removed from both sides, which is a plus.

It's replaced by a bristle-petal brush. The cap only comes off on one side, but the silicone and bristle inserts can be pulled out.

Overall, the robot is assembled quite well; there are no special comments regarding the design, although the plastic is clearly not the most budget-friendly.

Technical specifications

Let's take a look at the Yeedi K650's specifications. Key highlights include:

Type of cleaning	Dry and wet
Power supply	Li-Ion battery 2600 mAh
Suction power	Up to 2000 Pa
Opening hours	Up to 120 minutes
Cleaning area	60-80 m2
Height of obstacles	Up to 20 mm
Dust collector capacity	400 ml
Water tank capacity	300 ml
Overall dimensions	3350x79 mm

There are no complaints about the characteristics, the suction power is quite high, we will definitely test it further.

Functional capabilities

Now let's look at what the Yeedi K650 can do. All functionality is available in the proprietary mobile app, which you can download using the QR code attached to the robot. Installation shouldn't be difficult; just follow the prompts; everything is clear and simple.

On the first screen, you can immediately review information about past cleanings and launch automatic cleaning mode. Let's move on to the main control panel. The button on the bottom left is the on/off switch for magnetic strip support. If needed, you can purchase a magnetic strip to restrict movement; this is a very useful option, but unfortunately, it's not included.

This robot has three cleaning modes: perimeter, automatic, and spot cleaning. The lower right button forces the robot to return to the charging base. In the main settings, you can adjust the suction power (three levels in total), choose one of two cleaning levels, enable do not disturb mode at a specified time, set a cleaning schedule by time and day of the week, view the cleaning log, consumable status, and adjust the volume and language of voice notifications. Incidentally, this robot speaks Russian.

Additionally, you can change the robot's name, read the frequently asked questions section, and enable the robot's search mode by sound signal if it gets lost and stuck under furniture.

These are all the features of the Yeedi K650. It's definitely missing the ability to create a real-time map, but for this segment, the lack of mapping isn't critical. Many $100 robots move erratically and there's no way to adjust the power or wetness of the cleaning cloth, so these complaints aren't entirely objective. The lack of manual control, however, is a bit disappointing.

Testing

You can learn more about all the tests in our video review of the Yeedi K650:

Navigation

First, let's test this robot's navigation in a room with obstacles. The Yeedi K650 does indeed move in a serpentine pattern, and it didn't get stuck on the dryer. However, due to the obstacles, it got tangled up in the room and began driving along the walls several times, as well as in areas it had already cleaned. It didn't specifically sweep around the box or chair legs. As a result, it began moving erratically, which lasted for about half an hour, after which it was decided to return it to its base. However, it still couldn't find its base, despite passing near it several times. The navigation test in challenging conditions was a failure.

As for cleaning the entire house (34 square meters), the robot completed the task and was able to return to its base. It took over an hour (71 minutes) to complete the entire cleaning, but it covered the entire area, leaving at least no large, uncleared areas.

Navigating a prepared room is on par with budget gyroscope-equipped alternatives. The Yeedi K650 isn't suitable for large areas, but it's perfectly capable of cleaning multiple rooms.

Suction power

The suction power is decent for a robot vacuum with a turbo brush. It successfully removed debris from a 2 mm deep crevice.

This is the standard depth of the gaps between tiles, and for home use this power is quite sufficient, especially if there are no carpets or they have a low pile.

Dry cleaning of laminate flooring

The stand was scattered with debris in the form of hair, wool, ground coffee in the corners to simulate dust and various grains.

The Yeedi K650 cleaned almost all the debris, leaving some in the corners, like most other round robots. Hair got caught in the center and side brushes, but the bulk of the debris was collected in the dust bin. The test was passed successfully.

Cleaning the carpet

We scattered the same debris on the carpet. And as you can see, the Yeedi K650 cleaned the carpet perfectly, leaving no debris behind. The cleaning performance on carpets is excellent.

Wet cleaning

Now let's test how well this robot vacuum removes dried-on dirt from the floor. We first filled the tank with water and dampened the cloth. The removal performance is clearly above average. There were some minor streaks along the baseboard and minimal ones in the center of the stand, but we don't take these into account, as there was so much dirt that the cloth simply got clogged. The removal performance itself is high, and in real-life household conditions, such difficult situations almost never occur. I pass the test.

When it comes to wet cleaning on tiles, the Yeedi K650 wets the floor well, and after finishing the cleaning cycle, the robot was able to return to its base on its own. The floor was practically clean.

It's worth noting that the Yeedi K650 can vacuum and mop at the same time, which is a plus.

Obstacle clearance

Let's check the height of the thresholds the robot can overcome. It can even cross a 2-centimeter threshold without much effort. The cross-country ability is good.

Dark spots

However, the robot is wary of dark surfaces, recognizing them by their height differences. This is important to keep in mind.

Noise level

And finally, the final test was measuring the noise level in different modes. In Normal mode, the noise level reached 62.5 dB. In Maximum mode, it reached 67 dB. In Maximum+ mode, the peak was 67.4 dB. The robot is noisy, but it's also powerful, and that's important to understand.

Let's sum it up

The Yeedi K650 has been thoroughly tested. We're once again changing our robot rating system, and as the first robot tested in 2021, this one will be evaluated using the new format.

In the overall standings, the robot scored 39 out of 100 Possible points. Please note that the score may change slightly, as we are constantly adjusting the scoring algorithm to ensure a more objective score.

It would be interesting to hear your opinion about the new rating system in the comments.

But given the low price, I can say the following: the results are better than I initially expected. For a budget price, the Yeedi K650's build quality, package contents, suction power, and cleaning performance are quite impressive. And not every robot can boast the ability to electronically adjust the water flow, even for $150. So, this model is definitely worth considering, especially if the price drops to $100 on sale. My only gripe is with navigation, but this issue doesn't always arise. More precisely, it only occurs when there are a lot of obstacles in the robot's path. If the room is prepared before use, there shouldn't be any issues. So, this issue can be ignored.

On that note, I'd like to end this review. If you have any questions, please leave them in the comments. Happy shopping, everyone!
