Bottom Line
The iRobot Roomba 671 is a great robot vacuum with plenty of features to help make your life easier. It has great cleaning power and the self-emptying feature is definitely a plus. The mapping feature is also helpful in seeing where it has cleaned and where it still needs to clean. The only downside is the small dustbin capacity, but overall this vacuum is a great choice.

Planning to buy a robot vacuum?
When considering purchasing a robot vacuum, there are many factors to take into account such as price, features, and your specific cleaning needs. However, some of the most important aspects to look for are suction power, battery life, and self-cleaning abilities.
Suction power is important because it directly correlates to the vacuum’s cleaning performance. A higher suction power means that the vacuum will be able to pick up more dirt, dust, and debris. Battery life is also crucial because you want a vacuum that can clean for an extended period of time without needing to be recharged. Lastly, self-cleaning abilities are key for a robot vacuum because you want a unit that can clean itself after each use. This helps to ensure that your vacuum is always functioning at its best.
