We bought an LG Roboking a few months ago for about $750. DH was reluctant but he's been converted. There are pros and cons.

cons include:

  • Illogical system (to me). It goes over the floor a few times before it gets fully clean. At first I watched it and was getting frustrated at it for not being efficient. Then I realised I wasn't vacuuming, so got over myself
  • holds 1.4L of dust, as opposed to our Dyson which holds heaps more.
  • can miss bits and can't clean corners
  • freaks out the dog, though he knows to just move away. It sometimes looks like the bot is targeting him though
  • can struggle to get up on our large rug. It works out how to do it. It may just take a few times. The more expensive LG model can climb 20mm, ours can only climb 10mm
  • gets tangled in the tassels of the Turkish rug
  • is not as deep a clean as a normal vac with the Dyson


Pros:

  • I don't have to run a vacuum around every few days. I have SPD and vacuuming one room just kills me
  • even though it doesn't clean as well as a normal vac, it goes back to the dock, recharges and comes back out again to finish the clean
  • we can put it on in the living/dining at night. We close the door, it cleans that area. Recharges and does it again. Wake up to a clean room
  • we can put it on when we go out and come back to clean floors.
  • It announces when it's stuck/lost/needs recharging.
  • it can fit under the beds, so less dust under there
  • we only need to vacuum properly once every week or two.
  • I don't need to vac as much!
