I bought this product because a friend's house I saw a vacuum cleaner robot dune competing brand. He is very happy despite lancienneté the product. Jai a heavy back problem and the chore of vacuuming not narrange things. I thought it would be a help, i opted for the SR8990 as it sounds empty tank, cleans his brush, there are no great things to do for Lentretien. The surprise is huge! It is quune help, to test sounds effectiveness Navais I not spent vacuuming for a few days after its passage cétait superb. So it turns every day, my floor is tiled with a carpet entrance and also the good brush. The 2 terminals for virtual walls are views from Samsung.
