A slim, low cost entry to iRobot's wash and dry docks, with spinning pads that scrub spills well and a 3.29 in body that fits under low furniture. It has no camera, so testers saw it tangle in cables and push toys around. Buy it for mostly clear hard floors; skip it if you have cords or pet toys on the floor.

A near hands free Shark: it empties, refills, washes the pad in hot water and attaches or removes the pad on its own. Tom's Guide liked its carpet cleaning and mopping, but it sometimes got lost and its dock cord is only 0.4 ft long. At full price it costs as much as camera equipped rivals, so wait for a sale.

What reviewers found

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
Just A Dad Approved (6.2/10): Three months of home use: hassle free 7/10, mop 6/10, carpet 6/10, hair tangle 5/10, clutter 7/10. Pads occasionally detached and it missed cords and small objects. Source

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
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
