Verdict

The EZVIZ RE4 is a 2-in-1 robot vacuum and mop that features a robust 4,000 Pa suction power, LDS LiDAR navigation, and infrared obstacle avoidance sensors to map out up to 300 m² of flooring. Its core characteristics and pros include a generous 4,930 mAh battery delivering up to 240 minutes of runtime, an automatic carpet booster feature, a 300 ml adjustable water tank, and a slim 95 mm physical profile that easily navigates beneath low furniture. However, notable cons include its relatively small 350 ml integrated dust caddy that requires frequent manual emptying—as this standard variant lacks a self-emptying base station—along with a very basic, passive mopping pad design that lacks advanced scrubbing or weighted mechanisms.

  • Accurate LDS LiDAR navigation and fast, efficient mapping
  • Solid vacuuming performance on hard floors and good daily maintenance on carpets
  • Convenient self-emptying base (Plus model) reduces maintenance, with up to 90 days capacity
  • Effective obstacle avoidance for large objects and good drop sensing
  • User-friendly, functional app with customization options like no-go zones

What customers dislike about EZVIZ RE4?

  • Mediocre mopping functionality; merely wipes a damp cloth without active scrubbing
  • Main brush can be prone to tangling with pet/human hair, requiring regular cleaning
  • Less precise obstacle detection for small/low-profile items (cables, socks)
  • Occasional app mapping issues (shifting/random lines)
  • Slower charging time compared to some competitors
