I am selling the Lydsto W2 Edge robot vacuum and mop. It is a great automated way of vacuuming and mopping your hardwood or tile floors. I am moving and have no need for this anymore. I have two robots for sale (used one for the first floor and one for the second floor), that are about 6 months old. Like new.
Here is the spec of the robot: https://lydsto.com/products/lydsto-w2-edge-8000pa-robot-vacuum-mop
It is a great and versatile machine that automatically collects dust into a vaccum bag and also cleans the mop and collects dirty water in a tank (it also has a clean water tank). It learns the map of your home and can clean on a schedule. You can also use it without the mopping function on carpeted areas.
With this robot, you only need to empty the dirty water and fill up clean water once every couple of weeks. The dust collection vaccuum bag needs to changed only every other month.
