iRobot S9+ has a smart self-cleaning charging dock, Ecovacs T9 AIVI or Roborock S7 both have a vibration cleaning system and an AI camera to identify objects.iRobot S9+ (30 million VND)
iRobot S9+. S9+ is the most advanced robot vacuum cleaner from the American brand of robot vacuum cleaners – iRobot. The product comes with a dock that automatically collects garbage in the body. Users therefore only need to empty trash and dust from the dock instead of having to clean the drawer on the robot as often as with conventional products. The product uses the AllergenLock technology trash bag designed specifically for the S9+ to filter allergens such as pollen and mold. Half square and half circle machine, dual omnidirectional brush set, technology that is exclusive to iRobot, recently appeared on Ecovacs T9 AIVI series. Most of the latest technology on robot vacuums is available on the S9+, such as redrawing diagrams with a laser sensor using the vSLAM algorithm; identify obstacles, objects that cause obstacles, entanglement in the course of running; control via smartphone and map selection. Ecovacs Deebot T9 AIVI (13.5 million VND) 
T9 AIVI is Ecovac’s first robot line to integrate the Aeroforce dual-action rubber brush system shared from iRobot. As a result, the product has a higher suction efficiency, even with large garbage objects or stains sticking to the floor surface. This is also the top model with high suction power today, 3,000 PA, 300 ml garbage box capacity, 240 ml water box for cleaning, 5,200 mAh battery capacity. Compared with high-end robot lines, T9 AIVI has the most significant advantage of a vibrating cleaning system and an electric water regulating valve. The software on the machine also allows storing many different maps, suitable for multi-storey houses. Roborock S7 (12 million VND) 
Roborock S7. S6 Max proved “short of breath” compared to products from Ecovacs, Roborock has launched S7 with many technologies no less than the competition. The most significant upgrade is the Sonic Mopping water damper vibration mopping system that can vibrate 3,000 times per minute. The new wiping mechanism is significantly more effective than the old S6 Max series. However, the suction power of the machine is only kept at 2,500 PA and there is no dual rubber brush system like iRobot or Ecovacs. The S7 has a camera system that detects objects such as wires, socks, and baby items so that the device does not get entangled or entangled when operating. This camera can also be viewed directly from the phone. Neato Bootvac D7 (19 million VND) 
Neato Bootvac D7. Bootvac D7 from Neato has many similarities with iRobot S9+ in terms of half square, half round design. The company explains that this design helps to limit the omission of dirt in the corner. This is also a recognizable difference with most of the remaining robot models on the capital market, which are circular in shape. The machine also has a navigation system, laser map redraw, save multiple maps and select a cleaning area. Largest trash can capacity in the segment – 700 ml. However, the suction power of the machine is poor compared to competitors at 1,600 PA. Without the dual rubber brooms like Ecovacs or iRobot, the D7 has a broom that’s almost twice as long. The machine can also be controlled remotely via the application, schedule cleaning, create virtual walls …
