There are key factors that need to be considered before you decide to purchase a vacuum robot. If you have never done this before, here are some:

  • Maintenance

Be reasonable with your expectations. Even though this is a robot, it needs some maintenance time. It needs to be cleaned, bin emptied, battery recharged and replaced over certain time.

The newer the robot you buy, the less maintenance you will need to do. A lot of the new versions has brought us the set of improvements such as filtration and extracting.

However, that does not mean it will do everything itself.

Remember that you will need to buy replacement parts. Robot vacuums often fail after a period of time, and all of the biggest manufacturers have a secondary market where you can purchase a part that is broken. You do not need to send your robot back to its original manufacturer.

With a countless number of Internet tutorials, replacing a part is a piece of cake.

  • Auto-scheduling

Some of the newer robot vacuums have the power of auto-scheduling. This feature is vital for those who spend a lot of time out of the house.

Once you schedule your robot to clean daily, weekly or monthly and give it a particular time of the day to start, it will go automatic until you change its options.

  • Charging the battery

Robot vacuums run on batteries. They need to be often re-charged, and that is why a battery life plays a big role when purchasing a robot vacuum.

When buying a robot vacuum, keep in mind that it must have a minimum run-time of 60 minutes. Anything less than that is unacceptable, and it will waste more time than necessary.

From 60-80 run-time is average and something that most versions offer. Anything above 80 minutes can be considered high-end, and we highly recommend purchasing one that has 80+ minutes of run-time.

Some of the most recent versions have the option of an automatic return to the base where they charge.

When they finish recharging, they return to work and resume at the same spot where they left off.

They either can run until the battery dies and have to be manually be recharged or they can detect low battery, automatically return to base and resume where they left off, without needing any assistance from your side.

  • Performance

Obviously, the most important feature of every robot vacuum cleaner. In short, you need to figure out how well it cleans to know which one to buy.

Higher priced- Vacuums that belong to the higher priced category are Roomba 980, Botvac Connected, Roomba 880 and Samsung Powerbot. These vacuums have the near or matching cleaning power of traditional ones that are manually handled by human hand.

Lower priced- In this category you have cleaners that have a purpose of light maintenance. Lower priced options are for those who would love some free time from everyday cleaning but still have enough time to do a traditional vacuum cleaning from time to time. So if you decide, for example, to buy the Bissell SmartClean or the Neato XV-21, you will need a traditional vacuum cleaner on the side.

Mid-priced- These are the type of cleaners that offer capabilities of higher priced robot vacuums but lack in certain features. They often struggle with corners or different surfaces thus they are slightly cheaper than the cleaners in a higher price range.

A great example of a mid-priced robot vacuum cleaner is Roomba 770.

  • Size does matter

But not the size of the cleaner itself. The size of your apartment or your house plays one of the key roles you need to be aware of when purchasing a robot vacuum.

As mentioned above, robots with longer battery live belong to a higher priced group. Battery life is tightly connected with the size of your apartment. You do not want to purchase a vacuum with a low battery life and find it dead between rooms when you come home.

Botvac and Roomba have a range of different features and accessories that help navigate their products throughout the house. Botvac has a marking tape specially made for him and Roomba has a virtual wall lighthouse method applied.


Price plays an important role when purchasing any kind of product. A lower- priced robots cost between $300 and $400. Higher-priced cost between $800 and $900.

You can even find a cheaper robot for less than $300 but they are not designed for excessive maintenance, they do not offer a long battery life and they certainly are not for those looking to automate the entire process of cleaning.

Special deals on the last year’s models are something you should be looking for. These models are not modern enough and do not have all of the features but they are still doing a great job. A Roomba 870 is one of such.
