Buying Considerations

Robot Vacuums

At this point, you’ve probably picked one of the robotic cleaners we reviewed. Finding robotic vacuums at an affordable price may seem impossible, but they do exist.  

The key to picking the best one is in considering all the important buying factors. Take a moment to discover these factors as we discuss each. 

Price Point

The most critical thing to mention is that robot vacuums typically cost much more than 100 dollars. These are the top of what the market has to offer, often featuring the most innovative high-end technology. For this reason, they tend to cost as much as $800 on average.  

Robot vacuums under $100 are essentially the same, but they usually lack the high-end tech voice commands, Wi-Fi connectivity, and Google Assistant compatibility. 

They are cordless, battery-operated, and can usually avoid collision and cliffs. In most cases, that’s pretty much all they can do while vacuuming and mopping. 

If you’re on a budget, then you might want to consider something else than a robot vacuum as they tend to be a bit more expensive. And so if that’s the case, we recommend that you check out our best vacuums for under $100 guide.

Your Expectations

Right of the bat, it’s really important that you lower your expectations. Robot vacuums are fun and innovative, but more affordable models might not be as impressive, more expensive ones.  

If you’re looking for a robot vacuum that connects to Wi-Fi and has every possible cleaning mode, you should be ready to pay far more than $100. 

For this reason, you should understand the price and features ratio. Most of those highly innovative features come at a price that’s usually far higher. 

Features

Robot Vacuum

As we mentioned, robot vacuums under $100 lack some of the most innovative features. However, these features are often not as necessary anyway, and most robots can do a great job without them. 

For this reason, you’ll find affordable robots that come with different sets of features. You should pick and choose among these controls and specifications based on your needs and preferences. 

Affordable robots may have sensors, dual brushes, automatic recharging, and variable speed. However, they almost always lack Wi-Fi connectivity, suction power settings, a HEPA filter, and Alexa or app control. 

Run Time

Most robot vacuums under $100 come with weaker batteries than what you’d find on more expensive models. However, in most cases, you’ll get at least 90 minutes of run time.  

More powerful batteries are usually expensive, so this is a way for manufacturers to cut a bit on the overall price. 

Charge Time 

As you probably noticed, most robot vacuums need at least 150 minutes to recharge, although that time usually ranges from 3 to 4 hours. 

This might seem like a lot, especially once you consider that these vacuums typically run for no longer than an hour and a half. 

Flooring Type

Cheaper robots vacuums aren’t as versatile as more expensive ones, so make sure to consider the type of flooring you have. Most of these models can only clean hard floors as they tend to struggle with rugs and carpets.  

Some can handle area rugs, but that’s about as versatile as they get when it comes to flooring type.

Cleaning Tasks

As we mentioned, robots cannot replace your full-size vacuum. They’re meant for quick cleanups and spot-cleaning, especially those models that don’t have as many different features.  

Cheaper robots are meant for simple maintenance, so don’t expect them to remove embedded dirt and dried stains regardless of the floor surface. 

Suction Power

Most of these robots have sufficient suction power to tackle everyday dirt and debris on hard floors. However, they don’t have enough suction to extract embedded dirt from carpets or any other surface.  

Also, their suction power depends on the battery as well. In other words, you’ll notice the suction reducing as the battery life comes to an end. 

Dust Bin Capacity

Much like all robots, cheaper models are rather small. While this is perfect for tight areas, it also means that they have small dust bin capacity.  

Some models have light indicators that tell you when you should empty the bin. How often you’ll have to do this depends on the particular model you go for. 

Noise

Level of Noise

All vacuums have to make some noise, although some are louder than others. Luckily, the price usually doesn’t indicate how loud or quiet the robot vacuum will be. 

In other words, even some of the most expensive models are quite loud when compared to cheaper options. 

Wheels

All robots have wheels regardless of their price. However, you have to be careful about whether the wheels are gentle enough not to damage your hard floors.  

Cheaper models tend to have low-quality wheels, so make sure to double-check whether they could scratch your flooring. 

Cleaning Pattern

Most robot vacuums under $100 don’t have smart navigation or pre-scheduled cleaning patterns. These models usually work in circles, cleaning randomly as they go. 

This isn’t the most convenient way of cleaning, but it does get the job done eventually.

Width & Height

Width and height are among the most important factors when it comes to convenience and versatility. Low profile and compact housing mean that the vacuum can fit under furniture, efficiently cleaning all the remote areas of your floors.  

Still, make sure to double-check the dimensions as some robots are larger than others. 

Ease of Use

These vacuums are the easiest to use, although their price indicates exactly how simple they are. Robots are made to work with minimal assistance on your part. 

Robots under $100 might require a bit more assistance when it comes to recharging. Some also tend to get stuck in different areas, which means you’d have to help them out. 

Brush Design & Quality

Look for a robot vacuum that has rotating brushes that extend its reach. These help pick up the dirt and dust that’s usually located in corners and edges.  

Brush quality is another thing you want to pay attention to, especially if you have hardwood floors since you don’t want the brush to damage the surface. 

Robot Performance

Sensors

As you probably noticed from the robots we reviewed above, those under $100 typically don’t have as many sensors. Luckily, most of them will have cliff and collision sensors, and that’s pretty much all you need to keep the robot vacuum safe from falling and breaking. 

Warranty

Warranty is always important regardless of the price you’re paying for your vacuum. Some manufacturers offer longer-lasting deals while others cut back on this. 

Look for a reliable brand that stands behind its product by offering a long-lasting warranty and customer service. 

Filtration

Although a HEPA filter is a popular choice, it’s something you’ll hardly ever find in robots under $100. However, most of these models still come with reliable filtration systems.  

Choosing between these options depends on how sensitive you are to dust and whether or not you have pets. 

Modes

Robot vacuums typically have at least one extra cleaning mode, allowing versatility and convenience based on the floor types you have.  

More affordable models usually have spot-cleaning, low-power, and high-power suction modes, although many of these vacuums have no modes at all. 

The Ultimate Robot Vacuum Guide

Robotic Cleaner

Do you know how robot vacuums work? Most people are impressed by these self-operating vacuums without understanding how they work without your assistance.  

Take a look at our short guide below as we explain what robots are and how they operate. 

What’s a robot vacuum, and how does it work?

Robots are self-operating, compact and cordless, working without or with minimal assistance on your part. They’re meant to supplement a standard, full-size vacuum, helping to keep your floors between two sessions of using one.  

You can run a robot vacuum every day, depending on your needs and how dirty your floors get over a certain period of time. If your floors don’t get as dirty, running the robot vacuum every day will help keep your floors spotless. 

iRobot Roomba is probably the most popular robot vacuum, and we’re sure that you’ve heard of it. Roomba 960 and Roomba i7 are the two best-selling robots, but they cost far more than $100. 

Still, more affordable robots work in a similar way to deliver satisfactory results. Cheaper models often don’t have as many innovative features, but at the end of the day, they clean the floors just fine. 

Although they don’t require much of your attention, every robot vacuum still requires you to empty its dust bin. 

Preparing your house for a robot vacuum

Robots can get stuck in places regardless of how expensive or smart they are. More advanced (and expensive) models have sensors that help avoid obstacles, but they can still tangle in cables and curtains. 

For this reason, it’s important that you prepare your house before you run your robot. The first thing to keep in mind is that its charging dock requires space. Your vacuum needs space so that it can line up with its base before docking properly, which is critical for successful recharging. 

Remove all cables and hazards such as LEGO pieces, metal screws, and other similar items. These things can damage any robot vacuum, even the most expensive one. Cords can be especially annoying because a robot will inevitably damage any cord it comes across. 

Also, unless your robot vacuum can mop as well, you want to avoid water and liquid of any sort. 

Prepare Your Home

Robot Vacuum Pros

Robots are usually compact and small, which allows them to fit under furniture. Most vacuums cannot fit there, so having a robot for that purpose is rather convenient.  

Still, the most significant advantage of robot vacuums is their ease of use. These vacuums are usually easy to use and ideal for floor maintenance. They’re great for spot-cleaning, ensuring that your flooring is always spotless between using a full-size vacuum. 

Another great thing is that robots can usually also work as mops. Even some of the more affordable models we reviewed have this feature. 

Robot Vacuum Cons

Much like all vacuums, robots have drawbacks as well. One of the most significant setbacks is the fact that you have to prepare your home before running a robot vacuum. As we mentioned, you have to remove all the cables and possible hazards which can be quite annoying. 

Also, these can get stuck in pretty much anything from curtains to carpets. Some models can clean area rugs, but most of them cannot handle high-pile carpets. 

More affordable models either don’t come with a docking station or struggle to find it before the battery runs out. 

Conclusion

Robots are probably the most popular innovations in the industry of vacuum cleaners. They’re convenient and quite fun to use regardless of the flooring you have. 

However, they can cost up to $1800, which is quite pricey for most people to pay for a vacuum cleaner. Luckily, more affordable options exist. Hopefully, you found yourself the best robot vacuum that’s on a cheaper side. 

We tried to keep our list versatile so that there’s something for everyone based on the different types of floors. Make sure to think about your preferences and needs as well as your budget before opting for any vacuum in particular. 

If you struggle to find yourself a robot vacuum, we suggest you go back to our reviews and buyer’s guide. The information included can help you pick one among the many models we reviewed.
