Togruta echolocation allows them to ignore cover and concealment, which essentially removes any associated penalties to the Togruta's perception check. It doesn't say that that it foils stealth checks entirely.
As far as force cloak goes, doesn't force cloak just affect electronic surveillance? I can find it under the Jensaari force talents, but I haven't found it elsewhere. Do you mean the Cloak power? That says it applies to visibility, a form of concealment - which Togrutan echolocation ignores. So, in a sense it does see through it, but doesn't make detection automatic.
As far as the Miraluka force sight goes, it's very similar unless the character being perceived has some way to hide from the Force itself. The Miraluka character can make the perception check despite the stealthy character's attempt to be hard to see or hear, but nothing here guarantees the perception check will succeed, just that penalties that will hamper a normal sighted character will be negated.
Both races are pretty good at detecting things, but neither is completely foolproof if the stealthy character is really good and achieves a better result than the Togruta character or Miraluka character's perception check.
