What Is a Robot Vacuum?

Like traditional vacuum cleaners, these suck up the dirt from different types of carpet and flooring. However, unlike the more conventional canisters or uprights you’re probably used to, robot vacuums aren’t operated manually.

Instead, they have sensors that guide them. They work autonomously and don’t need to be pushed or pulled.

What happens when a robot vacuum encounters a wall or a piece of furniture? It will turn and begin moving and working in a different direction.

Why Should You Buy a Robot Vacuum?

A self-guiding cleaner certainly sounds cool. But is that enough reason to consider getting one? If you’ve never owned a robot vacuum, you may be wondering what all the fuss is about.

These are some of the benefits you can look forward to, even with a budget model.

Saves You Time

Do you have a busy schedule and no time to clean? With a robot vacuum, you can leave your device to get the work done, without you there to push it along.

It’s an autonomous device that can vacuum on its own. All you have to do is select the cleaning mode and personalize the scheduling settings. Then, whether you’re home or not, the robot will get the cleaning done.

Clean All Flooring Types

A good thing about robots is that they don’t just clean a single type of flooring. Like most vacuum cleaners, they will refresh your carpets, agitating the fibers to remove dust and debris. But they aren’t limited only to rugs.

Most robot vacuum cleaners will also do a great job on hardwood and tile floors. A lot of models can automatically adjust for the surface as they clean. This includes changing the suction power or brush roll.

Also, you’ll find some robot vacuums have climbing wheels to transition smoothly between flooring of varying heights.

Ideal for Those With Mobility Problems

If you suffer from back or joint problems, vacuuming can be excruciatingly painful work. The good news is that robot vacuums do the job for you. Use a remote control to customize your cleaning schedule, and sit back and relax while the work gets done.

Use Less Electricity

When you use an upright or canister vacuum, it has to be plugged in. It’s continuously using electricity as you clean. But, since a robot vacuum uses rechargeable batteries, it may even help to lower your electric bill (1).

Customize to Your Needs

You’ll find that a lot of robot vacuums offer different cleaning modes. This is great for gearing it to your specific needs. For example, if you have ground-in dirt, you can use spot cleaning.

For walls and corners, on the other hand, select edge cleaning. The specific modes will depend on the unit you buy, but most have between two and four different settings.

Clean Hard-to-Reach Spots

The floor or carpet underneath your furniture is a narrow space usually off-limits to larger canister and upright devices. However, these areas are not a problem for robot vacuums. They typically have a slim and compact design to glide into hard-to-reach spots.

With accessories such as sweeping side brushes, robots can get into the nooks and crannies around your home.

This includes edges and corners that traditional vacuum cleaners can’t reach. Without a robot, you are usually stuck cleaning these areas by hand.

Choosing the Best Budget Robot Vacuum

Like most technological gadgets, you can find robot vacuums to suit practically every budget. Of course, some budget models might not be as advanced as the more expensive ones. But this doesn’t mean they’re less effective at cleaning.

Here is a list of features often included even in lower-cost models. Keep these in mind when thinking about which one you want to buy.

Noise Level

Do you have young kids or pets? Your children’s naptime can be the perfect opportunity to get some housework done. But it won’t help if a loud vacuum cleaner wakes them from their nap. Likewise, you don’t want a noisy machine that might scare your dog (2).

The best way to avoid this happening is by choosing a robot vacuum with a low decibel rating. Ideally, look for one with a noise level of under 60 decibels (3).

A device with a lower level should let your children sleep, and your pets remain calm. It may also allow you to relax and watch television without being disturbed.


One of the reasons why you may be purchasing a robot vacuum is so you don’t have to do the work yourself. They can save you a lot of time, especially if you have a big home. In this case, therefore, you want to be sure to get one with staying power.

The feature to look for is a long runtime on a single battery charge. Affordable robot vacuums can last anywhere from 30 minutes to 120 minutes before needing a recharge. A higher runtime, though, means more cleaning will be done.

Smartphone App

A remote control is excellent for controlling your robot vacuum when you’re inside the house. This is a standard feature with many models. What’s even better, is if it has a smartphone app too.

You can only operate the device from within your home with a remote control. However, with a smartphone app, you can start cleaning and check up on your robot vacuum when you’re at work or out shopping.

Some even let you schedule cleaning to take place at specific days and times. So, you can arrange to come home after a long day to a house with clean floors and carpets.

Virtual Walls or Boundary Strips

Do you want to keep your robot vacuum contained in one area? Are there particular rooms (ones with napping babies, for example) that you want it to avoid?

In this case, you may want to look out for a model that offers virtual walls or boundary strips. This prevents the unit from leaving a designated area – it’ll turn around when it reaches a no-go zone.

Virtual walls are often created with a smartphone app, requiring a Wi-Fi enabled robot vacuum to work.

Boundary strips, on the other hand, are accessories included with your device or bought separately. You place them on the floor to mark where the vacuum shouldn’t go.

HEPA Filter

A high-efficiency particulate air or HEPA filter is an excellent feature to look for if you’ve got allergies. This filter can capture microscopic particles from your home, including bacteria, pet dander, and pollen.

A robot vacuum with a HEPA filter will release less dirt and dust back into the room (4). This reduces allergy symptoms, such as sneezing, skin irritation, and wheezing.

Dustbin Capacity

Since these vacuum cleaners are much smaller than traditional models, their storage capacity is also less. The size of the dustbin on a robot can range from as little as 0.2 liters up to 0.6 liters.

So, it’s best to look for a large dustbin capacity to make your life easier. This saves you from frequently stopping the robot vacuum to empty it. You may also want to consider how easy it is to empty.

Dustbins located on the side of a robot vacuum tend to be easier to empty. They slide out with minimal mess, and you can grip them properly. Plus, a dustbin underneath has a higher chance of spilling dust since they can be difficult to remove.

The Best Affordable Robot Vacuums of 2021

Because you deserve to find affordable robot vacuums, our team has located the top five. Before recommending products, we research them extensively, reading their specifications. We’ve also analyzed reviews from customers who have used the product, to find you the best.

1. Opodee Smart Navigation Robotic Vacuum Cleaner

Most Affordable Robot Vacuum with Powerful Suction

Do you want to make sure you capture everything – from small dust particles to large debris? In that case, you may want to choose this robot vacuum.

We’re very impressed with the suction power of this model, delivering 1800 pascals of vacuum pressure.

The unit is powered by a 2500 mAh lithium-ion battery. This provides up to 100 minutes of runtime on a single charge, and recharging will take four hours. A solid blue line will show when the battery is at full capacity.

The incorporated HEPA filter ensures that fine dust particles are captured.

This robot vacuum is suitable for hard floors and carpet, transitioning between the two easily with climbing wheels. There are four cleaning modes – edge cleaning mode, spot cleaning, single room model, and s-shaped cleaning mode.

When the vacuum runs out of battery, it’ll automatically return to the charging dock. It’s also self-navigating, to avoid obstacles in its path. We love that there are anti-drop sensors to avoid falling down stairs or any gaps.

The two wheels mean that it can transition smoothly from laminate, tile, or hard floors to low pile carpet. Plus, it can climb up to 16 millimeters.

If you’ve got sleeping children, you may not want the robotic vacuum to enter their room. Thankfully, this model includes boundary strips which will limit where it goes. Place them at the door entrance, and the machine will turn around and move in another direction.

It has a large dustbin for bigger cleaning jobs, with a capacity of 0.6 liters. Included with your purchase are four side brushes, a charging dock, and boundary strips.

Why We Love It

Powerful Suction

This one has the most powerful suction on our list. It boasts 1800 pascals, which may pick up outside dirt, food, and dust particles.

You Can Create No-Go Zones

With boundary strips, you can limit where your robot vacuum goes in your home. They’re easy to set up ­­– just attach them to your floor.

Four Cleaning Modes

We love that this unit has four cleaning modes to choose from. You can select one to suit your needs, whether you’re doing a quick clean-up or a more thorough weekly vacuum.

Keep In Mind

It Might Be Noisy

This robot vacuum is around 65 decibels. You may find that this is quite noisy if you have a quiet home. It’s certainly louder than some other models. So if quiet is a priority, this might not be the best choice for you.

2. ILife V3s Pro Robotic Vacuum

Best Affordable Robot Vacuum for Pets

Another budget robot vacuum we love is this one from ILife. It’s an ideal unit for pet owners.

For one, it has the manufacturer’s AirAway technology for additional filtering. It also has two long spinning brushes to capture hair from shedding pets. Additionally, the HEPA filter may help to trap pet dander and other allergens.

It can clean any floor surface, including hardwood, tile, and thin carpets. The vacuum is powered by a substantial 2600 mAh battery.

You can choose from four different cleaning modes. These include auto, spot, edge, and schedule.

The auto clean follows a random pattern to vacuum your home, while spot is good for ground-in dirt. For walls and corners, though, you may want to opt for the edge cleaning mode. You can also create a specified start-time on the schedule option.

Everything can be done directly from the remote control. Simply select the mode you want and press “clean.”

You don’t have to worry about this robot vacuum bumping into furniture or falling down the stairs. It has built-in obstacle-drop sensors on the front to safely guide the device. With a height of three inches, it also has a low-profile design.

The runtime on this model is around 100 minutes. That’s more than enough for cleaning lots of rooms in your home. When the robot vacuum runs out of battery, it’ll automatically return to the dock and start charging again.

It recommends that you empty the dustbin and clean the filter after each use. And, you should replace the filter every month to ensure the most effective cleaning.

Why We Love It

Deals With Pet Hair

The combination of AirAway Technology, long spinning brushes, and HEPA filter can benefit pet owners. Say goodbye to your furry friend’s shedding worries!

Choose From Four Cleaning Modes

Features Climbing Wheels

With the climbing wheels, this robot vacuum can transition between floor types. They have a reach of up to 15 millimeters.

3. iRobot Roomba 614 Robot Vacuum

Best Affordable Robot Vacuum for Ground-In Dirt

If you have a lot of stubborn dirt in your home, you may want to check out this Roomba. It has innovative Dirt Detect technology which recognizes areas that need to be cleaned. It then concentrates on this area to scrub it thoroughly.

There’s also an edge-sweeping brush to tackle those hard-to-reach spots. It’s designed to work at a 27-degree angle and gets into corners and along the edge of walls without problems.

On the top of the unit are three buttons – spot, clean, and dock. You choose the one you need. There’s no remote control or smartphone app for this vacuum.

We like that you don’t have to worry about this Roomba crashing into anything. It has 360-degree smart sensors and can make more than 60 decisions per second. There are also “cliff detect” sensors to avoid high drops.

This robot vacuum can clean carpets and hard floors with its three-stage system. The multi-surface brushes loosen and trap dust and debris before they are sucked into the dustbin.

Also, the auto-adjust cleaning heat will adapt the height for different surfaces.

Like others on this list, the Roomba also automatically returns to the base for charging. Before then, though, you can expect around 60 minutes of non-stop vacuuming. It charges relatively quickly too — only takes three hours to become fully charged.

Why We Love It

Patented Dirt Detect Technology

One of our favorite features on this unit is the Dirt Detect technology. It’s patented by Roomba, and especially suitable for high traffic areas in your home. It works well on stubborn, ground-in dirt.

Keep In Mind

Doesn’t Have a Remote Control

This robot vacuum doesn’t have a remote control. You have to use the buttons on the top of the unit to operate it. Unfortunately, this is a lot less convenient than being able to control it from across the room.

It’s also lightweight at 4.7 pounds, which means you can easily transport it around the house.

One thing you won’t have to worry about is this robot vacuum crashing into objects. It has sensors that will detect obstacles in its path and force the device to move in another direction.
