Maybe hoovers furniture top to bottom (4)
I believe the answer is:
eats
'bottom' is the definition.
Although both the answer and definition are singular nouns, I cannot see how one could define the other.
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for eats that I've seen before include "what is on the Christmas menu" , "Gets tucked into the cake" , "meal" , "snacks" , "worries" .)
