Shark 750 vs iRobot 690

HEPA Filtration

Because of being equipping with the filtration of AeroVac, the Roomba 690 can’t win the Shark ION 750, which uses HEPA filter in capturing very small dirt and dust.


BotBoundary Strips is the typical features that we can find in The Shark ION 750.

The 9′ Strips and double connectors makes the models having ability to be assembled in many ways.

In contrast, we can see that the virtual barrier is used in the Roomba 690, which produces the light being visible to only the Roomba.

This boundary has capability of blocking an area up to 10 ft in length and switching on/off with no need to have the move the barrier.

You can also turn the Halo mode on if you want to block of a 4 ft in diameter part of your house or around an object and electric tools.

Even though there is similarity in these products’ price, you need to be concerned about the maintenance expense.

In this term, the Roomba is likely to be more economic in spite of the same price. You can check the exact maintenance fee in the chart below.

Because of participating of the third parties, the cost will be reduced.
