We got Its not good enough with cleaning and suction for big houses. May be enough for small house. It's light but pattern of cleaning is not in line or straight. Not good for tiles but good enough on carpet areas .On tile areas it clearly leaves visible dust. It's only if your very busy and cannot afford expensive ones

When operating properly it is great to have around. It generally finds its way around quite well. It can be almost entertaining at times and was named Jeffrey by my grandson. It does a good job on tiled floors and is OK on carpet. It has been repaired 4 times and is currently being repaired again. The most common problem is the right wheel becoming immovable. The area being cleaned is about 70 square metres. We anxiously await his release from hospital.

We got 2 dogs and polished floor and tiles - some Persian carpets etc... It's amazing how much dust a house generates every day. We love our Roboking - it makes a real difference in dust level in the house. It works well on all surfaces . Battery live is well equoiped to do our 150m2 house. If you leave cords or headphones on the floor - yes it does not like them and will ask you to remove foreign material - but that' only common sense. My wife no has recommended the machines to girlfriend and her boss. What better recommendation than that.

I turn it on and leave the room, it gets stuck on its own cord, between the wall and toilet, at the couch, at the TV unit and on the fireplace hearth! It gets stuck everywhere. By the time you help it five or six times it's flat and can't finish the cleaning.... It's as useful as a heater full of snow!
