Cleaning Structure of Robot Cleaner

1. Cleaning Structure - 2 types 

    <  Rotating Brush type > : iRobot, Samsung, LG etc.

      < Vacuum Inhalation type > MamiRobot
  

2. Strong and Weak point in each type.

It's hard to say which type is better than the other. It depends on the environment.
So preliminary purchaser had better take into consideration where the robot cleaner will be used.

 1) Rotating Brush type
     It has the rotating brush on the bottom, sweeping foreign substances in, and has the suction function as a supplementary means. That's because the space for rotating brush makes a gap and can not form enough vacuum between the bottom of the robot and the floor, reducing the inhalation power.
This styructure of cleaner is effective for cleaning the foreign material between the carpet furs and pick up a little rubbish like wastepaper or cigarette-butt with the brush rotated. Not for non-carpet floors.

 To sum up
 < Strong points >
- Effective for carpet cleaning
- Pick up watsepaper and visible debris

 < Weak points >
- Hairs and foreign materials are apt to be stuck around the brush.
- Not good for cleaning for minute dust and hairs
- Something dirty on the bottom of the device(especially around the brush)


 2) Vacuum Inhalation type
    This type was developed to overcome the weaknss of Rotating Brush type, appling the existing technology of the ordinary wired vacuum cleaner to the cleaning robot. It's designed the dust intake always sticks fast to the surface to form a strong vacuum. So this type is more suitable for cleaning home and office floor surfaces such as wood, marble, tile, linoleum, and most low pile carpets.

To sum up

< Strong points >
- Excellent in cleaning dust and pets' hairs
- Easy to clean and maintain the device
- No brush ; Stir up no dust while cleaning

< Weak points >
 - Hard to pick up big rubbish like crumpled piece of wastepaper, beans and the like
 - Not good for high pile carpet


3.  Conclusion
 You should do ask yourself about floor surface(whether carpet ot not) to be cleaned and which tpye of robot will be needed, before buy a new one.
