    Waste of money.
    Extremely unhappy with this product. I have given it a long chance but this product is useless. It takes 2 hours to vacuum a tiny house and I’m not even doing all the rooms. It only holds charge for a short period of time before it spends 10 minutes searching for the home base. It was also extremely disappointing how LG was completely unable to help with the setup process, telling me I may be charged when taking it to a repair centre. It was by fluke I asked my internet company and they supported me through it all.

    Great little addition
    Generally does a great job on all of the floors, mopping function is a bonus - has dropped out of wifi a couple of times, which makes it stop - mildly annoying when we're not home, but it is mostly a good machine that does its job well

    Love my new vacuum. Just don’t know how long the brushes and filters will last but I am sure to find out.
