Best Robot Vacuum Under 500

When making your choice, one thing you will notice is, all the robot vacuums in this list are quite similar in their overall design. But when it comes to performance and features, they differ. It’s crucial that you read the buyer’s guide below to make sure you pick the right robot cleaner for your needs.

House/Apartment/Room Size

Yes, you might be wanting the best robot vacuum under 500, but you should also consider the size of the area where you will need the device to clean. The power of a robot vacuum is limited to its size and its battery power. You need to pick a model that will be able to clean a whole area at a go without the need to recharge. A typical robot can clean up to 2,000sq feet area, if your apartment or room area is more significant than that, then you will need to get two or three robot cleaners.

Programmable Schedule

The goal of buying a robot cleaner is to get a hand-free cleaning which allows you to do other things while the robot cleans the house. The robot vacuum you buy should be programmable, allowing you to schedule the cleaning time. There many ways you can program your robot. Either through WIFI connectivity, remote control, onboard controls, Bluetooth connectivity, or even through Alexa voice control. So, the robot must have one of these technologies for scheduling to be possible.

Flooring type

Different robot vacuum cleaners work on different types of floors and carpets. You need to be sure that the vacuum cleaner you decide to buy can clean your rug. Mostly, the robot will clean the hard floors and low profile carpets. Others can also clean the tile floors.

Brushes, suction, and filters

The ability of the robot vacuum to efficiently clean your floors and carpets lies on the powerfulness of the brushes, suction, and the filters. I recommend you check the type of brushes used, its suctioning power, and the type of vacuum filters. The brushes should be able to reach the edges and the corners while also loosening dirt and debris of any kind from the floor.

On the other hand, the suction power should be powerful enough to pick all type of dirt, big or small for the surfaces being cleaned. Lastly, the filters need to be efficient sufficient to capture dust and allergens before they escape to the air. If you can get a model using washable model, which will be great as they are reusable and have an extended replacement period.

Mapping technology

Robot vacuum must remember the areas it has cleaner and not waste time cleaning them again. That’s why I recommend your robot vacuum choice should have a mapping technology. The cleaning will be much simpler and faster with it.

Avoidance technology

Robot cleaning without your attention means that the device should have some way of sensing obstacles and cliffs. The avoidance technology prevents the robot vacuum from hitting obstacles inside your home and also prevents it from fall off the cliffs and stairs.


Getting a robot vacuum cleaner allows you to have your free time either relaxing, taking a break, or even doing some other essential things in the house. That means the model you pick shouldn’t disturb you with noisy cleaning sound. It should do operate quietly without limiting its cleaning power.


One thing that many robot vacuum buyers forget to check is how tall the device is and if it will fit under their furniture and other restricted areas. You need to make sure that the robot vacuum you want to buy fits under the coffee table and sofas for thorough cleaning.


When making your choice remember to check the wheels on the robot vacuum, you’re about to buy. The model should have wheels which will allow it to move smoothly on the type of floor it can clean. The wheels also need to be soft on the levels and not scratch it as it progresses.


Will my robot vacuum cleaner clean pet hair?

It all depends on if the robot vacuum can suck all the hair. Any robot cleaner for hard floor and carpet can clean the pet hair, but the effectiveness depends on its brushes and suction. It for it to deal with pet hair, it should be designed for it.

Why did my robot cleaning cycle start working less effective as compared to the first time?

The key reason might be because of its battery showing signs of exhaustion. In that case, you have to reset the battery. Different devices have different ways of resetting the battery. Read the user’s manual for more on this.


With all the above information, you should now be able to find the best robot vacuum under 500 without a hassle. If you’re still having problems, pick any of the above models, and you will be good to go. Remember to check what each model offers before you buy. It should meet all your needs.
