. After using Nido vacuums for years and always having connection issues with the last two, I decided to try another brand. I tried two other $200 robot vacuums and sent them back. If forward and bought a shark, and that's what I think of us so far. As for the vacuum cleaner, I would give it five stars. The only problem I have is that the rest charges when you leave and the brushes sometimes prevent charging. because it gets between the vacuum cleaner and the charging station. As for the mop, I would only give it two or three stars. The main problem is that the liquid tank for the floor cleaning solution is too small. You can maybe only do a third of our floors that we have below. Although I like to use it in our bedrooms and on the second floor landing.
