Best models you can buy from Aliexpress
what do you expect from a cheap robot vacuum cleaner under 180$, the answer from V7s is remarkable. It has all the practical function that a robot vacuum cleaner needs. Except from basic cleaning function, it has 2 different mopping function: dry mopping and wet mopping which are very useful for families. Other useful functions such as drop prevention, remote control, Scheduling can cover 90% functions of daily use. It has a 500ml dust bin and 450 ml water tank for mopping, while large tanks make the machine too wide for tight area cleaning. V7s produces 60 decibels while cleaning which is quite acceptable. V7s takes 300 minute for recharging and provides 140 minute run time. It’s a pity that V7s doesn’t support phone control and its navigational algorithm isn’t as sophisticated as more expensive robot cleaners, however, it is not fair to compare V7s with robot cleaners twice of its price. The navigation system is the largest shortage of V7s, it is not as efficient and wise as expensive robot vacuum cleaner, it will just run until the battery runs out, however it can still clean your home, just costs more battery power. After all it is still a good budget option for homes with low pile carpet and bare floor. You can buy the V7s in Amazon, however you have to pay $260 plus shipping. While in the ilife official store on Aliexpress you can get the same model within 180$, what’s more, there are large discount during promotion season. You can have a change to buy V7s within 160$! So if you are looking for a budget robot vacuum cleaner under 200$, try V7s.
V8s is the upgraded version of V7s, it has 2-side brushes while V7s only has one. It upgrades its power and battery capacity which makes this machine impressive in endurance, so it is quite suitable for large house. IT has a screen on the top of the cleaner for information display. You can check cleaning time and cleaning mode on the screen and manual control the machine with 3 buttons below the screen. Those three buttons are home, Time clean and circular motion mode. Just like V7s, the V8s has no room mapping function, however compared with the V7s, the V8s has better navigational algorithm. It still cannot defeat robot vacuum cleaners with mapping function, but it has a large advantage in navigational algorithm compared with the V7s. the V8s has 4 available cleaning modes: Auto, Path Programmed, Edge and Spot. The difference between Auto and Path Programmed cleaning modes is that the robot moves randomly in the first, and uses its gyro sensors to move in a more “regulated” manner in the second, a technology hilariously titled i-Move by the producer. Just like the V7s, the V8s produces 66 decibels when operating in its max mode. It has a 750ml dust bin and 300 ml water tank, makes its diameter 1 inch smaller than v7s, which allow the V8s to clean in narrower space. On Aliexpress, you can buy the V8s within 220$, still a fine budget robot vacuum cleaner, as an ungraded version, the V8s has a lot of advantage which deserves its higher price, if you like the V7s, we recommend you to spend 40$ more for the V8s. Still the V8s has no accompanying mobile app or wireless connectivity, if you are looking for budget machines with more smart functions , try Xiaom robot vacuum cleaner.

Roborock is one of Xiaomi’s hardware partners, and the Roborock robot vacuum cleaner can be considered as the second generation of Xiaomi Mi robot vacuum cleaner. In fact, the Xiaomi Mi robot vacuum cleaner is also manufactured by Roborock, as Xiaomi changed its strategy to give more prominence to his partners, the second generation of Mi robot vacuum cleaner is named as Roborock robot vacuum cleaner. There are few changes in design aesthetic compared with its first-gen model, an obvious change is the water tank at the back bottom of main body, which add mopping function to the second-gen model, while the first-gen model only support dry cleaning. In hardware, the Roborock robot vacuum cleaner, also known as Mi robot 2, has better routing algorithm and more powerful motor. The first-gen model has a 1800 Pa motor, while the Mi 2 has a 2000Pa motor, which provides more cleaning power. Also it upgrades more useful algorithms for different surroundings, and more cleaning mode for different scene. You don’t necessarily need to use the Mi Home app to monitor the Mi Robot 2. You can start the cleaning by hitting the power button, and the robot does the rest by itself. But if you want to take a look at the vacuum’s cleaning route in real-time or get a detailed view of the cleaning statistics and remaining charge level, then Mi Home comes in handy. Overall the Roborock robot vacuum cleaner is a good upgrade over Xiaomi robot vacuum cleaner, it has a good upgrade in hardware and algorithm, but the significant upgrade is its mopping function, the price of Roborock robot vacuum cleaner is about 380$ on Aliexpress, while it saves 100$, if you buy its first-gen model, in our opinion, the upgrade of Roborock is good, but not good enough to bring significant enhancement in cleaning performance, so if you don’t care about mopping function, we recommend Xiaomi Mi robot vacuum cleaner as it is much cheaper and enough for home daily cleaning.
If you are looking for a cheaper robot vacuum cleaner with all the functions that Roborock has, the C30B may be a option. It support mapping, mopping, app control and virtual wall functions just like the Roborock robot vacuum cleaner. It even support voice prompt although it is not as practical as we imagined. The C30B is the newest model launched in 2019, which only costs about 230$, compared with the Roborock robot vacuum cleaner, it has almost all the smart functions of the MI 2, so if you want to experience all the smart functions with less money, the C30B is the best choice. However, the hardware of the C30B is not as good as the Xiaomi Mi 2, the battery of the C30B is just 2500mAh, only half of the battery capacity of the Roborock robot vacuum cleaner. And the pathing algorithm of the C30B is not as smart as Xiaomi Mi 2 due to our tests, although the C30B has mapping system, the pathing performance in irregular space and narrow room is not as good as Xiaomi MI 2, and it has higher possibility of malfunction. In a word, it is not as efficient as Xiaomi robot, but its pathing system is still Ok. Another advantage of the C30B is its powerful 3000Pa motor, offering powerful sanction and cleaning performance. However, as it only has 2500mAh battery, the C30B is easier to run out of power, so if you have a large house, you should consider this shortage carefully. In conclusion, costing within 230$, the C30B has an integrated performance in cleaning, smart function and pathing algorithm, if you want a robot vacuum cleaner within 250$ and experiencing more smart functions, you can give the C30B a try.
40$ cheaper than the C30B, the Neastsvor X500 also support app control and mopping function. It is suitable for house less than 150 ㎡, although it supports less smart functions, the functions of its app such as scheduling, mapping, remote control is enough for 90% daily requirement. The mopping function of the X500 is not efficient as we required, and its pathing algorithm is just so-so, luckily its basic cleaning function is pretty good, so for a 190$ budget robot vacuum cleaner with app control, it’s overall performance is remarkable among robot vacuum under 200$ on Aliexpress. If you are looking for robot vacuum cleaner under 200$ on Aliexpress, the X500 is a competitive candidate.
