Robot vacuums have come a very long way since they were first invented. When the first robot vacuums were released, they weren’t that good.

One of the biggest challenges was navigation. Robot vacuums had a very difficult time moving around and avoiding things like chairs, walls, and other obstructions. But, the general concept was very interesting, and a lot of people were excited to see where robot vacuums would go, and what they would turn into.

Today, robot vacuums have become some of the most popular vacuum cleaners available. Instead of being bogged down by the navigation difficulties that many of the earlier robot vacuums had, as well as the lack of decent suction power, robot vacuums have solved those problems and gone on to become some of the most convenient and efficient vacuum cleaners around.


Finding the right robot vacuum cleaner is still a challenge, in some ways. There are a lot of options available, and it’s not always easy to find the right one.

If you’ve been looking and looking, and still haven’t had a lot of luck finding the right robot vacuum, then this might just be the guide for you.

Coredy R500 vs R300

We’re going to look at four robot vacuums that Coredy has manufactured. While Coredy isn’t the most well-known manufacturer, that doesn’t mean that you should ignore them. The robot vacuums that they manufacture are excellent, and they consist of many great features that make vacuuming an effortless experience.

To start, we’re going to look at the Coredy R300. Then, we’re going to look at the Coredy D400, the Coredy R500, and, finally, the Coredy R650!

What Does The Coredy R300 Have To Offer?

The Coredy R300 is a robot vacuum that requires you to use a remote control. There is no smartphone functionality. Using this remote control, you have access to features such as scheduling along with being able to directly control the vacuum. There are, of course, other features, such as being able to access various cleaning modes.

Coredy R300 vs R400

When the Coredy R300 is moving across your floors and vacuuming, it uses 1400Pa of suction power. Many other robot vacuums offer more suction power than that, but this is less expensive than most other robot vacuums.

For the most part, you won’t have any issues with the suction power that this robot vacuum cleaner offers. It’s not always the most efficient, especially on thick carpets and rugs. But, it works great on just about any hard floor, and thinner carpets and rugs are easy for the R300 to vacuum.

If you need to adjust the vacuuming process, you can do that. On the remote, you have access to four different cleaning modes.

The first of these cleaning modes is “Auto Mode”. Auto Mode is when the Coredy R300 moves across your floors, cleaning and relying on its sensors. This is the most common mode, and it’s completely hands-off.

Then, you have “Edge Mode” and “Spot Mode”. Edge Mode is for vacuuming the edges of walls and objects in that room. It’s very useful if those edges are especially dirty. With Spot Mode, the R300 focuses on one particular spot in your home, and vacuums that spot up very thoroughly.

Finally, you have “Low Noise” mode. Low Noise mode is a mode that is, well, low noise. It’s when the Coredy R300 makes very little noise, and uses less suction power. If you have a simple and quick vacuuming that needs to be done, it’s a good mode to use.

On a single charge, the Coredy R300 gives you 110-minutes of battery-life. For a robot vacuum of this price, that’s a lot of battery-life.

Ultimately, the Coredy R300 is a very well-designed and useful robot vacuum. It’s one of the simplest robot vacuums available, but if you just need something simple, efficient, and convenient, you can’t go wrong with it!

What Does The Coredy D400 Have To Offer?

On the surface, the Coredy D400 has a much nicer aesthetic design than the Coredy R300. The design is slick, and very precise. But, when you look at the different features and attributes that the vacuum offers, there aren’t too many notable differences between the Coredy D400 and the Coredy R300. Except, that is, for a couple that are very notable.

Coredy R400 vs R650

To use the Coredy D400, you can use a remote control. But, you’ll probably want to use your smartphone, or a Google Assistant/Amazon Alexa device, because the Coredy D400 supports those.

When you are using your smartphone, you have access to all of the regular features that you’d expect, such as scheduling and the different cleaning modes. But, you can also access a map of the floor that the D400 is currently vacuuming.

Having this extra functionality is very useful, since it allows you to access the settings and features of the D400 at any time.

Another cool feature is that the Coredy D400 comes with two “Virtual Boundary Strips”. These are strips that you lay out in front of the areas that you don’t want the robot vacuum to cross. If you don’t want the D400 to clean your room, or to leave a room, you can lay out a strip in front of the door frame.

Other than that, the Coredy D400 is quite similar to the R300. You have 1400Pa of suction power, the same cleaning modes, and many of the same basic design traits. Although, you do have two-hours of battery-life, which is ten-minutes more than the R300.

If you’re looking for a robot vacuum that’s still affordable and efficient, but with smartphone functionality, the Coredy D400 is an excellent choice that improves on the R300!

What Does The Coredy R500 Offer?

The Coredy R500 doesn’t give you any smartphone functionality. You’ll be using a remote control to access all of the different features and settings that the R500 offers. But, it’s a very cheap robot vacuum, and it gives you, among other things, a mopping system.

Using this mopping system, you’re able to keep your hard floors nice and clean, free from dirt and dust stains that sometimes pop up as a result of vacuuming. This mopping system isn’t a replacement for regular mopping, but it’s very good at giving your floors a nice rinse and making sure that things are still looking nice.

When it comes to the suction power, you have access to 1400Pa. But, while the suction power is the same, the overall efficiency of the vacuum is a little better, thanks to a more elaborate cleaning system that involves brushing and sweeping. It’s not a huge difference, but if you need to vacuum on carpets and rugs, you’ll notice that it’s a little more efficient than the previous two robot vacuums.

Just like the D400, the R500 comes with two-hours of battery-life, and Virtual Boundary Strips. Having two-hours of battery-life ensures that you can vacuum for as long as you need. With the Virtual Boundary Strips, you’re able to tailor the vacuuming process to the exact spaces and rooms that you need to vacuum.

For what the Coredy R500 is, it’s great. It’s super affordable, gives you plenty of vacuuming power, and has a couple of really nifty features that keep the vacuuming process quick and easy!

What Does The Coredy R650 Offer?

When you look at the Coredy R650, you won’t notice much in the way of differences. It looks a lot like the previous Coredy robot vacuums, and, for the most part, it is.

Coredy R650

To use the Coredy R650, you’ll be relying on a remote control. There’s no smartphone functionality. But, this remote control keeps things easy for you, and it gives you full access to the various features and settings that are available.

Just like the previous two Coredy robot vacuums, you have access to Virtual Boundary Strips. These make it easy for you to tailor the vacuuming process to particular spaces and areas.

The big difference between the Coredy R650 and the other three robot vacuums is the fact that the R650 gives you 1600Pa of suction power, instead of 1400Pa. Now, that may not sound like a huge difference, but it is, because it gives you the freedom to vacuum on other surfaces with a lot more ease and efficiency.

There are two other differences, as well. When you’re vacuuming, everything flows through a simple HEPA-Filter, and then a sponge filtration system. These two systems keep dust and allergens out of your air.

When the stuff you’ve vacuumed up flows through those two systems, it flows into a large dustbin. This dustbin can hold 500ML of dirt, dust, and debris, so you don’t have to empty it as much.

Coredy R650 Robot Vacuum

Ultimately, if you’re looking for an efficient, powerful, easy-to-use, and very affordable robot vacuum, the Coredy R650 is a great choice! It doesn’t add much to the design that Coredy started with, but it’s still a great robot vacuum, especially if you’re on a budget!
