It doesn't really compare, but another man-eating, demonically possessed household appliance film is The Refrigerator (1991) https://www.imdb.com/title/tt0102767/reference . It's bad enough, but not truly, awesomely bad. Though Juan the Plumber must be the second best heroic plumber on film (after Brazil's Harry Tuttle, naturally).

It's fun enough, but The Refrigerator lacks the balls out weirdness of Death Bed: The Bed That Eats. Hausu https://www.imdb.com/title/tt0076162/reference may be a better comparison on that front, but I haven't managed to see that yet.
