Which Cheap Roomba is Best for Large Homes?

As show in the score sheet below (Table 1), all cheap Roomba cope rather well with smaller homes. You can even get excellent results with Roomba 650, Roomba 652, and Roomba 690. Among the three, Roomba 690 is our favorite. Essentially, you get much more for a similar price.

Conversely, no cheap Roomba would live up to large home owners expectations. Better go for other Roomba that better deal with large areas.

Which Cheap Roomba is Best for Carpets & for Hardwood Floors?​

To clean hard floors, any cheap Roomba would make a decent job. But, Roomba 652, and Roomba 690 achieve the best results as shown in Table 2 below. Thanks to their advanced dirt sensors, they are better at detecting dirtiest spots, and spending more time cleaning them.

The dirt sensor does impacts carpet cleaning results. But, the most important factor is suction power, especially with thick carpets. Inevitably, the only way to deeply clean a carpet and capture small debris is through high suction. Unfortunately, the Roomba 600 series have a rather low suction power. So, even Roomba 652, and Roomba 690 only achieve average results on carpets.

Which Cheap Roomba is Best for Pet Hair?​

Collecting pet hair is a task that all Roomba handle successfully thanks to the combination of a side brush and a main brush system. However, as shown by Table 3, this is not enough to meet all pet owners expectations. Indeed, there are other facets that you should also consider before choosing your Roomba.

The first important factor is time you will spend on maintenance. You should also be able to make your Roomba clean a specific area, or avoid some spot, such as the location of your pets bowl.

Let’s face it, cheap Roomba are simply bad regarding maintenance. They do have  rather small dustbins 400 ml (~13.5 oz) or less. So, you’ll have to empty it frequently. Besides none of them has a tangle-free brush. Last, although they all have a spot cleaning mode, only Roomba 630, Roomba 650, Roomba 652 and Roomba 690 are shipped with iRobot Virtual Wall boundary marker.

Which Cheap Roomba is Best to Fight Allergy?​

When you want to fight allergy, you need a vacuum robot that thoroughly cleans your home. It should suck all the dirt and capture even tiny allergen particles such as pollen or mites.

No one of cheap Roomba vacuum robots has a HEPA filter, so the smallest particles will be eventually expelled and remain in the air. Their suction power being low, they won’t deeply clean carpets. They will however collect dust at the edges, and spend more time cleaning dirtiest areas.

The best with this regard are Roomba 652 and Roomba 690 as shown by Table 4. By cleaning your home daily, they will still manage to reduce the amount of dust and allergens. Though, they are less efficient than Roomba that include HEPA high-performance filter.

Which Cheap Roomba is Best for Home Automation?​

The true added value of vacuum robots is automating your home cleaning. There are however different levels of automation. With the most basic automation level, the vacuum robot does the cleaning on its own. All vacuum robots do so. Moreover, all cheap Roomba are capable of self-charging. Nevertheless, you can expect more.

The next level of automation is scheduling. Only 4 robots in our selection do support scheduling. Those are the ones with highest scores on Table 5. Indeed, only Roomba 650, Roomba 652, Roomba 675, and Roomba 690, can start cleaning on their own. So, all you have to do is take care of maintenance from time to time. In other words, with these cheap Roomba, your home cleaning is almost on autopilot, though not 100%. Unlike best Roomba, cheap ones requires you to empty the dustbin and remove hair stuck around the brushes.
