Will this work with Deik mt820? Please before I buy a whole new robot and wife kills me.

I am not sure - but the pictures that I can find look like they world work. Th brushes and filters all seem pretty universal unless it is a really off brand.

How often should I replace the parts?

Depends on how much you run your vacuum... how dirty your house is. Filters can be cleaned with warm water a few times but your paper filter will get dirty. The cleaner everything is the more efficiently the vacuum can clean.

Is this package compatible with DeenKee D40?

Do not know, it worked for mine which is a Goovi
