## 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/)

## Frequently asked questions about the iRobot Roomba Plus 405 Combo

**Does the iRobot Roomba Plus 405 Combo empty its own dust bin?**

Yes. The station empties the robot’s dust bin after every run. The 2.5 l dust bag in the station lasts up to 75 days, the maker says.

**Does the iRobot Roomba Plus 405 Combo wash and dry its own mop?**

Yes. The station washes the mop itself. It then dries the mop.

**Does the iRobot Roomba Plus 405 Combo work with Alexa, Google Home or Siri?**

It works with Alexa, Google Assistant and Siri. It does not support Matter. Home Assistant has an official integration for this model.

**How high a threshold can the iRobot Roomba Plus 405 Combo climb?**

Thresholds up to 20 mm, the maker says. It has no climbing system for higher thresholds. Measure your own thresholds: the ones to a bathroom or balcony are often higher.

**Does the iRobot Roomba Plus 405 Combo fit under low furniture?**

The robot is 10.6 cm tall, so it fits under furniture with at least 11 cm of clearance.

**Is the iRobot Roomba Plus 405 Combo suitable for pet hair?**

The maker does not say so, and it lacks a brush that hair does not wind round or a station that empties the bin.
