## Verdict

A well rounded all in one robot that Vacuum Wars ranked #1 at review time, with top five carpet pickup, perfect pet hair results, strong obstacle avoidance and record threshold climbing. Battery coverage is below average, and a long term tester saw weekly dock clogs with a heavy shedding dog. The 3 year warranty is a real plus at this price.

### How long is the warranty?

The Dreame US product page lists 3 years, which is longer than most rivals at this price.
