For all of those wanting to have a robot floor cleaner
such as the Mint but not being able to afford such a luxury, there is always the choice of doing it yourself...with LEGO
! Pulito, was built following precisely this spirit.
The video below shows the robot navigating and cleaning around the house. It uses Swiffer pads to clean.
Pulito is even able to dock like a commercial cleaning robot as shown below.
