Based on ratings from across the web.
Reviews last updated: July 2026 · How we calculate this

What customers like about Viomi V3 Max

  • Excellent smart navigation and mapping with 360-degree LDS laser technology.
  • Strong 2,400 Pa suction easily captures fine dust and pet hair.
  • Vacuums and mops simultaneously, with electronic water control and Y-pattern mopping.
  • Long-lasting 5,200 mAh battery offers up to 300 minutes for large homes.
  • Very competitive value for a device with advanced features.
  • Slim design fits beneath most furniture and handles obstacles and carpets well.

What customers don't like about Viomi V3 Max

  • The dustbin can fill quickly with lots of pet hair and require frequent emptying.
  • Limited options for buying official replacement filters and brushes directly from the brand.
  • Customer service can be poor or slow when resolving technical or hardware problems.
  • Some users report radar errors and mapping-sensor problems after prolonged use.

Verdict

The Viomi V3 Max is a versatile 2-in-1 robot vacuum and mop featuring a 2700 Pa suction motor, a 5200 mAh lithium battery that delivers up to 215 minutes of runtime, and advanced LiDAR navigation supporting up to 5 multi-floor maps. Its main advantages include an exclusive manual-mimicking Y-pattern mopping mode, a quiet 57 dB operation, automatic carpet boost technology, and a 2-in-1 dust (400 ml) and water (200 ml) tank controlled via the Mi Home app. However, it can struggle to reliably detect and avoid certain low-profile obstacles like pet water bowls or shoes, and it lacks an automatic self-emptying base station.
