What to Look for in a Cheap Robot Vacuum

Keep these features in mind when choosing the best cheap robot vacuum cleaner.

accordion_icon

Navigation & Control

First, consider the navigation and control of your robot vacuum.

Cheap robot vacuum cleaners use infrared sensors to prevent them from colliding with obstacles or chair legs. And they’ll have a stair detection feature that senses when it reaches a ledge or step. So they won’t accidentally tumble down your stairs or fall off a ledge.

But, most affordable robot vacuums don’t come with smartphone app integration. Instead, you control them using a remote or buttons on the unit itself.

Cheaper robot vacuums are also likely to only clean your house in a random pattern. Whereas better models will vacuum in organized rows and straight lines.

Finally, they won’t have some of the most advanced options. For example, dirt sensors, mapping features, cleaning histories, or zone lines.

For instance, this iRobot Braava Jet 240 is one of the cheapest robot vacuum models on the market. It vacuums with single-pass cleaning in a systematic pattern.

However, this Shark AV911S robot vacuum is reasonably affordable. And it works with voice control such as Amazon Alexa and Google Assistant.

Cleaning Modes

Next, check if the affordable robot vacuum you’re looking for comes with several cleaning modes.

The best cheap robot vacuums can sweep up dust, dirt, and debris from your hard floors thanks to their standard spinning fan brushes. However, they can’t dig into the carpet to lift embedded dirt and dust from the fibers.

For this, you’ll need a vacuum with a brush roller or variable suction control:

  • As explained, a roller brush is helpful on carpeted areas. Especially for pet owners to clean up dog hair from the carpet fibers. For example, this Coredy R300 has an automatic lift feature for carpet cleaning, still at a reasonable price.
  • But regarding variable suction power, only expensive models will have this feature to adapt to multiple floors and surfaces. They’ll also have specialized modes such as spot-cleaning mode or double-pass cleaning. So if you want these features, you’ll certainly have to add a few dollars.

Suction Power

You should also consider the suction power on your robot vacuum.

Robot vacuums tend to have less suction than traditional vacuums because they have smaller motors. However, quality robot vacuums have the suction power to lift and capture debris or pet hair from any hard surface.

The power on a robot vacuum is usually measured in Pa (Pascal Pressure) units by the manufacturers. And this can range from 1000 to 4000 Pa.

For example, this affordable Eureka Groove NER300 has 2000 Pa of suction power. But it’s important to note that Pa is a unit of pressure and doesn’t reflect the suction power of the vacuum.

Instead, you should check CFM (cubic feet per minute). This refers to the amount of airflow that is used to suction up the dirt.

accordion_icon

Battery

The battery life on your robot vacuum is an important feature to consider. Especially if you have large areas to clean.

Make sure you find a robot vacuum that has a long run-time. This way it can clean your whole floor area before it returns to its charging dock.

For example, this Neato D3 Connected runs for up to 60 minutes before returning to the charging base.

accordion_icon

Height

Next, consider the height of your robot vacuum. This will determine how well it can clean tight or narrow spaces.

In general, most entry level models have a height of 3.5 to 4-inches. So they’ll be small enough to clean areas you can’t reach with a traditional vacuum. Such as under furniture or cabinets and other tight spaces.

But if your robot vacuum is too tall, it won’t be able to fit into these spaces to clean them. Or your vacuum may get stuck.

So make sure you measure the height of these spaces and compare it against the size of your vacuum. This way, you can know that it will be able to clean under your furniture or cabinets without any hassle.

Noise Level

Finally, you want to consider a budget-friendly robot vacuum with a suitable noise level. Most robot vacuums are quieter than traditional vacuum cleaners.

But, some do produce a high-pitched whistle or a mechanical grinding sound while they’re cleaning. Especially the cheapest ones.

And this is something to consider if you plan to be home when your robot vacuum is cleaning. In this case, consider a budget friendly robot vacuum with a noise level of 55dB or below. This is the same noise level as most normal conversations.

For example, this Bobsweep Bobi Pet has a noise level of below 60 dB.

Otherwise, consider a model with variable power settings. This way, you can set it on a lower cleaning mode for a quieter clean when you need it.
