My husband wasn't on board when I bought the robot vacuum because he said it wasn't as clean as we were. After using it for about a week it switched sides lol. We have a 2 year old and a dog. No matter how much we clean, there is always food/crumbs/hair on the floor. After a week of use we have noticed that there are no more hairs on the floor and we no longer step on crumbs or rice (my dog eats chicken and rice for dinner), it's really amazing. The robot needs some time. find my way back, but it always happens and it's fun to watch my daughter. This robot vacuum cleaner saves us a lot of time and is very affordable compared to the big brands. Big brands might be more appealing, but for us, getting the job done and affordability are key, which is why PureClean is selling this robot vacuum.
