Features of Hobot Legee 669:

Cleaning stages:

The Hobot Legee 669 has double features of vacuum and mop so the engineers have made 4 stages of cleaning in this mop robot. The four functions or the stages include vacuuming, wiping, spraying, and mopping step by step.  In each step, a cleaning procedure is formed. Have a look at our demonstration.

  • Stage 1:When the side brush is brushing on the floor through its hair, the suction mouth in the front will vacuum simultaneously. It will suck in all lightweight dirt and hair.
  • Stage 2:There are basically two brush cloth underneath this robotic vacuum and mop. The first brush cloth within the front will do the dry brushing, rubbing off the dust stains.
  • Stage 3:The wet mopping feature in this mop robot will do the water spray on the floor. This will soften the tough stains for further cleaning.
  • Stage 4:In this final stage, the bush cloth at the back end will erase the dirt stains.

Cleaning Modes :

This one has three cleaning modes. In automatic mode, the robot cleaner will clean the entire surface area. The quick cleaning mode will have parallel movements. The third mode is thorough cleaning in the perimeter.

Smart Navigation Technology

The Hobot Legee 669 is effectively functional because of its smart navigation technology. Hobot has an exclusive patent license. The Laser lights, Encoder, Gyroscope, E-compass, and Estimation map are its components. They all work together to navigate the path and protect the device from any collision and going in the wrong direction.  The three laser lights at the front of this robotic vacuum and mop work as eyes. They detect the random things in the way and navigate a path for the mop robot. If anyone of these lights is not working, there is a chance that it won’t be able to navigate properly.


The Hobot Legee 669 is a premium cleaning robot. It has vacuum and mop cleaning features and it is super easy to use on any hard floors. It does effective cleaning, especially if you have large non-carpeted flooring space.
