We've had Numatics since the early 80's. When they were steel and didn't have names like Henry and George.
Parents do about a house build/renovation every two years. Apparently no project is complete until you've sacrificed a Henry.
There's only so much sawdust and plaster dust one fat little guy can ingest apparently.

Mrs Hell has a posh little Miele thing, but when I changed my rent-out house to renting by a family I reclaimed my five year old Henry, who was just fine. Local holiday camp bought three Dysons one year. By the end of the season the only vacuum cleaner left working was the three year old Henry.
