Interesting to know about the Dyson! One of the reasons I was going to buy one was the appeal of being able to put all the tubes and plastic components into the sink for a good soak and cleaning in hopes that it wouldn’t stink. Have had our roomba for a year and surprisingly it doesn’t smell at all, limited use case and more supplemental than a real vacuum replacement but still. Curious as to why some stink with animals and others not.
