It's icy outside, too icy to walk the dogs, too icy to take them in the garden (the access over the patio faces north-east and is still treacherous). Grandson has taken them out there for a play, meanwhile, after doing a bit of work from home, I've resorted to cleaning behind the dogs' crates. Guess whose hair blocked up the little Dyson!
It turned out that the filter was broken, but still!
