I put one in Mom's Lux Legacy.
I'm sorry, but I can't really comment on its effectiveness. I only got over there once a week, and that was before social distancing. Now, I haven't been in the house in a couple of months, at least.
When I was visiting regularly, I rarely used the vacuum. Mom can't use it at all any more, and I don't think the folks that live there to assist her use it much either.
There's a little cordless Dyson that I think they use occasionally, and one of them will sweep the hard floors more often than not.
Sorry I can't bring more to the table. If and when I get to visit there again, I'll try to give it an evaluation.
