Do I Really Need A Vacuum Robot?

If you like vacuuming your home several times a week, then you don’t need a vacuum robot! For the rest of people, go get one! You’ll save time for work, or relaxing alone or with family and friends. Your place will remain clean with almost no effort. All you have to do is empty the dirt bin from time to time.

Having a vacuum robot is especially recommended if:

  • you have pets
  • you have young children
  • you or your family suffer from allergy
  • you are a caregiver to an elderly or a disabled person

For people suffering from allergies, you need to pick a vacuum robot with high performance filter. Those are the ones with filters that capture smaller particles, including pollen.

But wait! Even the best robots can leave some dust, especially at the corners. So, don’t throw away your old manual vacuum. You’ll still have to use it, much less often though. Checkout the video blow.

Are Roombas Good for Hardwood Floors?

The short answer is yes. Roombas are very suited to vacuum hard floor. That’s true for all vacuum robots.

Roomba side brush cleans wall edges

Roomba Counter-Rotating Brushes Break Debris

On Roombas, the cleaning system ensures maximum efficiency through a combination of brushes and suction. Actually, Roombas rely on two brushes: a main brush and a secondary one. The latter spins on the edge. It captures dust along the side of the robot. Hence, even if the Roomba is round, it still cleans wall edges.

The main brush is located on the bottom of the robot. It collects debris and hair and channels them into the suction path of the vacuum motor. On Roomba 800 series and the high-end 900 series, the main brush is more efficient that ones found in most other robotic vacuums. It is indeed made of two counter-rotating dirt extractors. They break down dirt into smaller parts easier to suck, resulting into improved cleaning. Besides, the counter-rotation avoids hair getting entangled. This means less maintenance for you. No need to clean the main brush, as with other vacuum robots.

Last, Roomba has a dirt sensor that improves the cleaning. It detects areas with high concentrations of dirt, dust, and pet hair. Those are typically around the dining table or high-traffic zones of your home. The Roomba is capable of detecting
these spots and spend more time cleaning them.

Roomba: Which Roomba to Choose?

There is no doubt that the iRobot Roomba is among the best and most durable vacuum robots. Yet, it’s not easy to pick one because there are actually many Roombas on the market. They have different features and accessories. Their prices also vary in a wide range: from $200 up to $900.

Our guide provides with a detailed comparison of different Roombas. They are spread over 3 categories, each meeting a specific need. We list below the best Roombas for each of these categories.
