Good product following the descriptions. Delivery on schedule, on my vacation spot. Reasonable noise compared to a traditional aspi. Save time to do other things while the aspi work but think of storing son at the other objects that could géner. It lacks in my opinion a programming time during the passage of the aspi in small rooms if one is absent, as it runs for two hours until the new refill. I recommend this product, it is time to let the robots to work for us. But do not neglect the thought of cleaning it you will make much more lontemps.
