Performance Summary

The Roomba i3+ EVO is the robot vacuum that actually gets used — its auto-empty base means owners go weeks without thinking about it. After 28,000 owner reports over 12+ months, the pattern is clear: set it up once and it reliably handles daily maintenance without intervention.

Pros

Auto-empty Clean Base holds 60 days of dirt — eliminates daily emptying
iAdapt 3.0 navigation learns your home layout over time
Compatible with Alexa and Google Home for voice scheduling

Cons

Struggles with very dark carpets (sensor confusion on black surfaces)
Clean Base bags are proprietary — ongoing $10–15/bag cost

What Sets It Apart

Ultraviolet Cleanse Tech ➔ Exposes water to UV light ➔ Kills 99.9% of bacteria in the water tank before misting.

Air Multiplier Projection ➔ Distributes hygienic mist evenly ➔ Prevents wet spots or condensation on carpets.

Intelligent Climate Control ➔ Measures temperature and humidity ➔ Prevents over-humidification automatically.
