Performance testing and metrics

Mopping feature

I test each robot vacuum for at least a month, sometimes sharing initial impressions earlier. Long-term testing helps identify issues that may not be apparent initially, like mapping errors or brush roll problems.

Factors to consider when choosing a robot vacuum

Choosing the right robot vacuum involves considering your home's floor types, the importance of mapping and obstacle avoidance, battery life, and suction power. For example, homes with mostly carpet might not need a high-end mopping feature, while those with pets could benefit from strong suction and effective pet hair handling.

Frequently Asked Questions

How do robot vacuums work?

Robot vacuums use a suction system and a brush roller to pick up debris, which is then stored in a dustbin. They navigate using sensors and a mapping system to clean autonomously, avoid obstacles, and return to their charging dock.

How long does the battery last on a robot vacuum?

Battery life varies by model, typically ranging from 60 to 160 minutes. Higher-end models tend to have longer battery life, and most can recharge and resume cleaning mid-session.

How do robot vacuums handle pet hair?

Many robot vacuums are designed to handle pet hair efficiently, featuring strong suction and specialized brushes. Some even have built-in detangling systems to keep the brush clear during cleaning.

Do robot vacuums require maintenance?

Yes, regular maintenance is necessary, including cleaning and replacing filters, emptying the dustbin, and checking brushes for tangles. Self-emptying models require less frequent intervention, but all need some level of care to perform at their best.
