WHOS THAT SOMTHING...(non-relation to pokemon)

First topic message reminder :

SO, I think my little pokemon game would have been more fun if it wasnt about pokemon, because some of us have no knowledge of pokemon what so ever. How about we have the same game, but with objects....
FOR EXAMPLE

Me: THIS OBJECT COOKS STUFF
Kevin: a microwave
Me: No
Jando: An oven
Me: No. it makes something crispy
Helen: A TOASTER
Me: YARS

You all know the rules by now.... ILL START

This object cleans stuff.

Larz u fail..... y ur giving up the answer? ¬¬

I couldnt think of another clue without making it obvious :X
Errrrrrr SOMEONE ELSE GO.

The pairs part of it threw everyone off.

Ill go i guess, This thing is only one color, but can be several sizes. This object is always on the bottom, but can easily fly. This object can be seen in the sun but not in the rain.

WHAT AM I?

(PS. THE SMELL OF BALSANIC VINEGAR IS DISGUSTING)

I thought about this one for a good 5 minutes but cant get anything.

DUST! O:<

Or any form of dirt/soil? Soil turns to mud in rain so technically you dont see its dry form
