OMG! Where has this been all my life? What a great hunt! Here's my opinion:
Pros:
- Lightweight and compact. Easy to transport and store.
- A considerably extensive warranty.
- Saves you time and work.
- By making use of the technological resource you will no longer have to perform this annoying task.
Cons:
- The battery only lasts 20 minutes. Not ideal if you want to clean several windows or glass doors, for example.
Thanks for review :) I appreciate~
