Tbh neither Mum nor Dad can really use a washing machine anymore. A case of whatever we buy will outlast them both anyway. It'll be the carers using it. The problem is compounded by Mum's mixed dementia. She will turn off, adjust mid cycle etc the existing machine then would until recently hang still soiled partially washed clothes out to dry. When she takes off clothes and immediately folds them and puts them in the airing cupboard/wardrobe is something else she's prone to. Wouldn't perhaps be so bad except for the double incontinence!
She still has the thing about buttons. A neon is like a moth to a flame for her. Lost count of the times she's switched off Dad's phone linked call button box (he wears the call button around his neck). I then get the call of a probable power failure but it's just Mum switching it off. Tbh he hasn't pressed the button the last two times he's fallen and been hospitalized.
They're living, kept alive by medical science but they're not living well.
One thing I would say is that I think MVHR would be a boon to assisting the elderly in remaining in their own homes a bit longer. Mum has a habit of shutting and locking all doors and windows, drawing the curtains then barricading with whatever she can find. The smell can be nauseating. That foul air can't be good for them anyway, leads to mould on the walls and ceilings and I imagine could contribute to some breathing, infection, possibly even dementia related illness. MVHR might even mean people visit them more.
Shoot me if I get to that stage please.
