Very useful in day to day, particularly kitchen and daily usage area to be cleaned. Very handy to just pick up vacuum and clean the area in a couple of minute. No need to cord it and wrap it up.
The battery is really great it last as it stated for 40 min on lower setting. We generally use medium setting it last for 25-30 min for us.
All those attachment are very well defined in the product based on very versatile use.
