It makes me a great service by cleaning (vacuuming) for me. No need to be a contortionist to get under furniture, more cord behind. At my age (74 years), this is a perfect servant who comes and goes, and returns where there is still a speck of dust. It is not talkative, he did his job and ranks when he finished by warning me. I waited too long before equip me and I recommend it to everyone and especially to those pressed for that, vacuuming becomes painful. However, I watch it so that everything goes well.
