Pros and Cons of Robotic Vacuum Cleaners (Easy Cleaning)

Going over all the robotic vacuum cleaner’s good and bad points will give you a clearer view of the product. This article features some pros and cons of robotic vacuum cleaners to help you make the right decision.

I was in the same situation, wondering whether one would be worth it. I don’t think it’s for everyone, so I’d like to present an argument for both sides.

Robot vacuum pros

Here are a few pros to do with robotic vacuum cleaners:

  • Autonomous cleaning: Keeping your floor clean without having to lift a finger.
  • Wi-Fi Connectivity: Allows you to take full control using an app on your smartphone.
  • Data monitoring: View the history of the robotic vacuum’s cleaning on your device.
  • Time-saving: This, to me, is their key benefit. If you are busy and cannot get to the vacuuming, this will be the likely decision-making factor.
  • Voice Control: Connect it to your voice assistant, like Alexa, for convenient voice control.
  • Mapping: The smart vacuum cleaner can map out the layout of your rooms, so it knows where it’s already been.
  • Different Surfaces: It can clean just about any type of surface, including rugs.

What are the cons?

Let’s have a look at some of the cons associated with it:

  • Maintenance: No battery lasts forever, not yet, anyway. You must consider replacing the battery when it’s not going far on a full charge. Other items, like brushes, filters, etc., must be replaced or cleaned regularly.
  • Corners: Hard-to-access corners won’t be cleaned very thoroughly.
  • Cost: Paying the initial and other maintenance costs might not be worth it if you can pull out the vacuum cleaner and do the job yourself.
  • Not quite there yet: Compared to the cleaning accomplished by an ordinary vacuum cleaner, the robotic vacuum cleaner isn’t up to the same level of cleaning.
  • Too many items lying around: If too many items are left about, it will diminish the area that it will clean as it cannot move these items out of the way.

What difference does the battery capacity make?

The longer the battery lasts, the longer the robot vacuum can do its job without returning to the dock.

As the battery ages, the vacuuming duration becomes less before it returns to the dock for charging.

What is the lifespan of the battery of a cleaning robot?

This can vary based on the battery quality chosen by the manufacturer.

Here are the different types of batteries commonly used in a robotic vacuum cleaner and their lifespans.

  • Ni-MH or NiMH (Nickel-metal Hydride): 180 – 2000 Cycles
  • Li-ion (Lithium Ion): 400 – 1200 Cycles

What is a cycle? Using a fully charged battery until it is fully discharged.

Having a look at the specifications of the smart vacuum cleaner will reveal the type of battery. This will enable you to compare it to the list above.

I realize this is a vague indication, but unfortunately, it depends on the individual manufacturers’ products.

I would try and find out from a local dealer how long the battery would last for each specific model you are interested in.

What other maintenance services are required?

Here are a few of the other items that need maintenance:

  • Brushes: Because of the frequent cleaning of the unit, brushes need to be replaced every 6 to 12 months. Some models are brushless and don’t need this maintenance. You still need to clean them every week. Twice a week if you have any pets.
  • Filters: New filters need to be installed every month.
  • Charging contacts: Every month, you must ensure the charging contact on your vacuum is clean, so charges remain effective.
  • Sensor lenses: These need cleaning every month.
  • Other miscellaneous parts: Other model-specific parts may need maintenance. This is like caster wheels and other moving parts. I cannot see this being more regular than a period shorter than about a month. You may want to consider other options if there are too many extras.

Does it keep out of my way?

If it bumps into your foot, it will immediately change direction. But I think a better way is to vacuum your house when you are at work or somewhere else.

You don’t want to trample over it when walking around the house, especially when carrying something.

Will it damage my furniture or parts of my home?

I wouldn’t say there is much of a risk short term. However, you might notice issues long term.

Places like walls or skirting might have marks on them over time. So if you are renting, it may be an issue.

As for the furniture, it’s unlikely, but not impossible for damage.

Newer models avoid contact completely. Some have rubber bumpers along their outer edges. So I think it could be a problem that will be nonexistent shortly.

Can it pick up my pet’s hair?

Most modern models have become quite good at dealing with pet hair. It’s not perfect but does a fairly reliable job.

I have noticed it’s not good at getting ingrained pet hair out of the carpet. So you may want to get a deep clean before setting the machine loose on its regular cleaning missions.

How well does it cope with getting on and off rugs?

It was surprising to see that they handled obstacles like getting onto thick rugs quite easily.

It varies by the degree of ease, depending on which model negotiates the carpet.

This particular activity doesn’t depend on the unit’s price.

How often must it be emptied?

With most of them given their limited size, you need to empty the bin after each vacuum.

So you will probably be emptying it every day.

Will a robot vacuum handle stairs?

Will it vacuum the stairs? No. But it will avoid them. So you won’t have one of these come crashing down the stairs.

The movement in that direction will cease when it senses the floor not being fully present around or under it.

Sensors allow it to know when this happens, and it will proceed in the opposite direction.

How does it work around pets?

Generally, this shouldn’t be a problem. This is true, especially if your pets don’t have a problem with the cleaner.

Some dogs love playing with it, and I imagine certain pets wanting to ride on it.

It will come down to your pet’s personality, but hopefully, they will simply leave it to do its work.

Make sure that it doesn’t clean anywhere near your animal’s feces. This could lead to a trail being smeared around your house. Some could also be tracked along in the small treads on the wheels. So it’s important to be aware of this.

There will also be cases where a pet won’t like this machine. Although it will occur in the minority, it’s still possible.

Unfortunately, I don’t have a perfect solution for you. The only thing that comes to mind is to ask someone you know (or that they know) who has one to try out.

The robotic mop

Some higher-end models of the robotic vacuum cleaner also have a mop feature.

There are also robotic mops. Their sole purpose is just to mop.

Some of them have pads that collect the dirt off the floor. Others are more elaborate and can do a light brush and vacuum. Some can release a small amount of spray so the pads can pick the dirt up easier.

It operates the same way as the robotic vacuum cleaners in terms of controlling it.

So this could be a separate purchase for keeping your hard surface floors clean.


A robotic vacuum cleaner can help you and is a product worth mentioning as a housekeeping gadget that can make cleaning easier.

But honestly, you won’t be getting rid of your existing vacuum cleaner. If you have stairs, you still need to vacuum them.

So let’s sum up to determine whether one is worth it.

I would say that your lifestyle would be the determining factor. However, it doesn’t take long to quickly run a vacuum cleaner over the floor every couple of days.

If you have little time and extra money lying around, then yes, it might be for you.

But if you are on a tight financial budget and have some spare time now and again, I’d pass on it.

Would spending around $200 – $500 and dealing with the maintenance be worth it for a surface-level autonomous clean?

Maybe it would, but on the other hand, I could easily vacuum a four-bedroom home in under half an hour.

I’d like to see what these products will be like. Give it another 7 or 10 years, and I’ll likely have a different view of them. Perhaps even a bit sooner.

That’s it for the article. I hope that you have the desired information you need.
