## Pros

- Swept up surface debris of every size on hard floors and carpet (Vacuum Wars, https://vacuumwars.com/roomba-plus-405-combo-review-great-hopes-ok-results/)
- New single brush roll resisted long hair tangles far better than older Roombas (Vacuum Wars, https://vacuumwars.com/roomba-plus-405-combo-review-great-hopes-ok-results/)
- Dock reliably empties the bin, washes and dries the mops and refills water (Vacuum Wars, https://vacuumwars.com/roomba-plus-405-combo-review-great-hopes-ok-results/)

## Cons

- Weak at lifting embedded dirt and flattened pet hair out of carpet (Vacuum Wars, https://vacuumwars.com/roomba-plus-405-combo-review-great-hopes-ok-results/)
- Only one water setting, and it leaves floors far too wet (Vacuum Wars, https://vacuumwars.com/roomba-plus-405-combo-review-great-hopes-ok-results/)
- The app was repeatedly buggy throughout testing (Vacuum Wars, https://vacuumwars.com/roomba-plus-405-combo-review-great-hopes-ok-results/)
