While I review a wide variety of robotic vacuums, there are two brands that I cover extensively. One of them is Yeedi.
Yeedi's mandate is to manufacture sturdy and dependable robotic vacuums at a price anyone can afford. While Yeedi is seldom the first company to feature an innovation, its products tend to include improved and more mature versions of these features.
Today I am taking a close look at the Yeedi Vac 2 Pro. This new robot vacuum features a 3D obstacle avoidance system and the company's newly developed vibrating mop. Although the Vac 2 Pro comes with a standard dock, I have decided to pair it with the optional Self-Empty Docking Station.
The Yeedi Vac 2 Pro is 13.4 inches in diameter and rises three inches from the floor. An auto mode pushbutton and a navigational camera are mounted to its deck. A white plastic cover conceals the robot's dustbin, power switch, reset button, and wi-fi indicator.
Either a blank module or the mop assembly can be fitted to the edge of this robot. Flanking this component is an assortment of anti-collision sensors, including an advanced 3D Obstacle Avoidance system.
The Vac 2 Pro is equipped with a 5200mAh lithium battery capable of powering the Yeedi Vac 2 Pro for over three hours.
Two large rubber-coated drive wheels, an omnidirectional wheel, one side brush, six drop sensors, a carpet detector, a floor tracking sensor, and the main brush are located beneath the robot. A pair of metal contacts used to charge the battery are positioned near the front. Two outlets allow debris to be sucked from the vacuum when connected to the optional auto-empty dock.
No-go zones may be configured using the Yeedi application. Accessories consist of the charging dock, user's guide, and brush cleaning device.

Visual SLAM (simultaneous localization and mapping) systems determine the orientation and position of a robot by creating a map of its environment while simultaneously tracking the device's location.

The algorithm's points of interest are tracked through successive camera frames to triangulate a 3D position. This data is used to create a 3D map and identify the robot's location. The robotic vacuum derives this information from photographing the ceilings of the rooms being cleaned.
After mapping is complete, the robot can now determine both its location and that of surrounding objects. This information allows the vacuum to navigate a room while efficiently bypassing chairs and other obstacles.
3D Obstacle Avoidance
This system utilizes structured light technology. The time it takes for emitted light to be reflected back to the robot's sensor indicates the presence and distance of an object.
The robot successfully tracked and avoided a coffee cup, my cat's food bowl, and the bathroom scale during my tests. While this represents a significant step forward in avoidance technology, it failed to note a small semi-transparent bottle and a monitor cable. There is room for improvement
The Yeedi Application
The robot's companion application allows the user to schedule cleaning, set up a virtual boundary, and choose a specific room to vacuum. In June, an update is planned that will allow the user to merge and split rooms. Later in the year, another update will add the ability to store multiple floor maps.

The Mopping System
Most mopping robotic vacuums include a flat mop pad fastened to a mount that hangs loosely beneath the vacuum. When the robot crosses the slightly raised thresholds that divide rooms, the mount will pivot upward, allowing the mop to slide over the obstacle. However, because this system fails to provide downward pressure, the most it can do is remove a thin layer of dust.
The Yeedi Vac 2 Pro's mop pad is fastened directly to the bottom of the mop assembly, allowing the mop to apply enough pressure to clean a floor properly. This affects the robot's ground clearance, but the robot can cross all but the highest thresholds due to good balance and plenty of power.
The mop pad vibrates back and forth at a rate of 480 times per minute. While this rapid repetitive movement increases the noise level of the robotic vacuum when mopping, it also significantly improves its ability to clean.
A carpet sensor located at the bottom of the robot ensures the vacuum will not attempt to mop a carpet, rug, or mat. During my tests, it first cleaned around my Turkish rug. Then it slowly circled the carpet again, climbing onto it enough to mop the floor area immediately alongside without dampening the carpet.
The Yeedi vacuum easily navigated my area rug and the well-secured Turkish carpet.
A black colored metal grating guards the air intake located within my front foyer. While this obstacle sometimes traps the wheels of unwary robots, the Yeedi vacuum carefully edged around it.
While vacuuming, this robot can cross thresholds—the strip of wood at the bottom of doorways where rooms connect—of up to two centimeters (0.8 inches). Because my dining room's floor is 1.25 inches lower than neighboring floors, I have installed narrow ramps between them. The Yeedi vacuum efficiently handled these hybrid thresholds while vacuuming. However, when mopping, it could not mount the three-inch ramp that moderates the difference between the level of my dining and living room floors. Either the rise in level was too significant, or the robot mistakenly believed the ramp was a carpet. Unless your floor plan includes sunken floors with ramps, you should not experience this difficulty.
The Yeedi Vac 2 Pro is shipped with a standard dock that can be used to recharge the unit. I, however, opted for the CH1918 Self-Empty Station. This device saves time and effort by sucking the dust and debris from the robot's dustbin and storing it in a 2.5L dust bag. The dust bag should be replaced every month.
This robotic vacuum is fitted with a 5200mAh lithium battery capable of providing power for up to three hours. My medium-sized house can be cleaned within 55 minutes in standard mode, bringing the battery level down to 74%.
The Yeedi robotic vacuum cleans one room at a time using a pattern determined by information derived from its internally developed map. Specific rooms may be targeted for individual cleaning using the Yeedi application.
Suction can be turned off or set to 600, 1500, or 3000PA. I use the lowest level because it cleans my house well in conjunction with the side brush and an exceptionally effective main brush. When this mode is selected, I can barely hear the robot unless I am occupying the room it is cleaning.
The drip rate, which determines how fast water is delivered to the mop, can also be adjusted.
The Yeedi Vac 2 Pro boasts good maneuverability and is fitted with a VSLAM navigational system that allows mapping. Battery life is excellent, and the new 3D Obstacle Avoidance system increases the robot's ability to evade entrapment. I found the optional self-empty station to be a helpful upgrade.
This robot is equipped with a capable mopping system designed to save its owner time and effort. If you are searching for an effective robotic vacuum that can also mop, the Yeedi Vac 2 Pro is worth a close look.
