### iRobot Roomba Plus 415 Combo + AutoWash Dock

- Ideal Home: UK test: cleared a BBQ sauce spill in one pass and reached skirting boards, but tangled in charging cables, pushed toys and wrapped hair on the roller. Notes 45°C pad drying versus 75°C washes on some rivals. [Source](https://www.idealhome.co.uk/house-manual/floorcare/irobot-roomba-plus-415-combo-review)

### Shark PowerDetect ThermaCharged 2 in 1

- Tom's Guide: Hands on review: carpets looked clean after a full run and mopping lifted muddy paw and shoe prints. First map took about 10 min, but the robot got lost once looking for the dock and air blasts sometimes pushed debris the wrong way. No lab measurements published. [Source](https://www.tomsguide.com/home/home-appliances/shark-powerdetect-2-in-1-thermacharged-nevertouch-review)
- Woman and Home: UK month long test: cleared test debris in 1 to 3 passes, hair did not tangle the rollers, and it reached 80% charge in about 30 min. Mapping an open plan room took about 90 min with two bin empties. [Source](https://www.womanandhome.com/homes/cleaning--decluttering/shark-thermacharged-powerdetect-wet-and-dry-robot-vacuum)
