Xiaomi has listed the Mijia Robot Vacuum 4 on JD.com ahead of its 2026-04-07 launch, pricing it at 1,443 yuan or about $210 (€193). With regional government subsidies applied in some areas, buyers can pay even less, making this one of the cheapest robot vacuums in its class. Despite the budget positioning, the spec sheet offers features that typically command a significant premium from competitors like Roborock and Dreame.

The headliner is 10,000 Pa of suction, a figure rarely seen at this price point. Navigation relies on LDS laser rather than the cheaper camera-based systems that often populate budget offerings. The closest US equivalent is the Roborock Q7 M5+ with matching 10,000 Pa suction, currently selling for about $250. The Mijia Robot Vacuum 4 includes four cleaning modes, dual anti-tangle side brushes designed to handle long hair, a 520 ml dustbin, and a 270 ml water tank capable of covering up to 300 square meters (3,229 square feet). The 5,200 mAh battery runs for 180 minutes in standard sweep-and-mop mode.

Obstacle clearance reaches 20 mm (0.8 inches), enough to handle most door thresholds without getting stranded between rooms, though it falls short of Xiaomi's higher-end models with their more advanced climbing capabilities. The design follows Xiaomi's familiar all-white aesthetic, and the inclusion of LDS laser navigation at this price remains relatively unusual outside China, where most Western brands charge a $100-plus premium to move from optical bumping to proper laser room mapping.

The Mijia Robot Vacuum 4 goes on sale 2026-04-07, and even without regional subsidies, the $210 price converts to a figure that undercuts most comparably equipped alternatives from Roborock or Dreame. The combination of 10,000 Pa suction, laser navigation, and dual anti-tangle brushes at this price point positions Xiaomi as a formidable competitor in the budget robot vacuum segment.
