Pros & Cons of iRobot Roomba 640

Doesn't Have Mapping / Path Planning Feature

No Smartphone App / Wi-Fi Support

The cleaner does not support Wi-Fi and doesn't have a smartphone app.

Amazon Alexa Not Supported

The model is not compatible with any voice assistant such as Amazon Alexa or Google Home and cannot be controlled by voice.

Doesn't have a HEPA filter

Doesn't have HEPA filtration, but is equipped with another type of filter.

Doesn't have Wet Mopping Feature

This robot vacuum doesn't have a mopping feature and can sweep only.

Noise Level

The device is noisier (compared to other robot vacuums) when operating, even though it is still not as loud as an upright vacuum.

Powerful Battery

It is equipped with a powerful 3000 mAh battery that lasts longer than most robot vacuum cleaners.

No Scheduling

The robot cannot be scheduled to automatically start work at a specific time.

Has a virtual wall function
