Coredy R3500 Design
The design of the Coredy R3500 robot vacuum is extremely simple and easy to use. It has a sleek, black body with minimal silver and bright blue accents.
The controls on top of the vacuum are very limited.. in fact, it’s just one button.
Pressing the button turns the vacuum on and allows you to start a cleaning cycle.
All additional controls and settings can be adjusted using the remote control. The controls on the remote control includes:
- Run auto mode cleaning cycle
- Return to charging base
- Schedule a cleaning
- Spot clean
- Edge cleaning
- Max mode
- Manual directional steering
What is on the underside of the Coredy?
- Side spinning brushes (qty: 2)
- Bristle-style brushroll
- Contact sensors (for charging)
- Edge sensors (for drop detection)
- Clear view into the dust bin
- Wheels (qty: 3)
- Power switch
Designed into the dust bin, there is also a washable HEPA filter. This helps to reduce maintenance costs, while still effectively removing those finer debris particles.
The Coredy R3500 has a few different cleaning modes which can be handy for variable cleaning jobs.
- Auto Mode – This cleaning mode will automatically adjust suction based on floor type. Although this model does not have digital mapping technology, it is able to clean until the battery gets below 15%, which is when it will automatically return to the charging dock.
- Edge Cleaning – When edge cleaning, the Coredy R3500 will navigate around the perimeter of the room, using the spinning side brush to capture debris along baseboards, edges, and corners.
- Spot Clean – For spot cleaning, you place the robot vacuum in the area you want cleaned. It will move in a circular pattern, working its way further outward until the area is clean.
- MAX Clean – In Max mode, the R3500 will run at its maximum suction power. This mode is designed for higher traffic areas or high pile carpets or area rugs.
Size & Dimensions
The Coredy R3500 is a little smaller than other robot vacuums on the market today. This is especially true for the height, as not many robot vacuums are under 3″ high.
- 12.5″ in diameter
- 2.7″ tall
- 5.6 pounds
Accessories & Parts
The Coredy R3500 comes with a basic set of parts and accessories for general use. I will add that the remote control is a nice addition, as not all robot vacuums comes with that tool.

Coredy R3500 Performance
The cleaning performance of the Coredy R3500 was just okay in my opinion. It consistently had a problem with pushing debris along edges and into corners and then was unable to clean it from there.
Hardwood Floor Cleaning
On hardwoods, the Coredy R3500 had the best cleaning performance of any floor test.
The results of the hardwood cleaning test were pretty good.
On average, this robot vacuum was able to capture about 92.5% of the cleaning debris.
The debris that it struggled with was consistently pushed along the edges or into the corners of our testing lane.
Once displaced, the Coredy had a hard time picking up debris from these tight spaces.
Low Pile Carpet Cleaning
On low carpet, we noticed a similar trend, in terms of performance.
The Coredy R3500 was only able to capture about 76.5% of debris tested on low pile carpet.
Similar to the hardwoods, the Coredy pushed debris to the outer edges of our testing lane and was then unable to pick up the debris from there.
This was mainly a struggle for finer debris particles which is why the image above looks like it cleaned most of the debris, but in reality, there were some issues.
High Pile Carpet Cleaning
Different floor type, similar story. On high pile carpet, the cleaning performance was identical to the performance on low pile carpet.
The Coredy was able to capture about 76.5% of all debris tested on high pile carpet.
Like with the other flooring types, the Coredy struggled here with debris along edges and corners.
If you have a mostly open-concept floor plan, the edge and corner cleaning may not be as big of an issue, but it’s certainly something to consider.
Usability & Maneuverability
The usability of the Coredy R3500 robot vacuum is pretty good and intuitive.
To setup this robot vacuum for a cleaning, you’ll need to:
- Charge the vacuum. (can take between 4-5 hours for a full charge)
- Start a cleaning cycle by pressing ‘start’ on the vacuum itself or by using the remote control.
- Let it get to work.
Before first time use, there is also a bit of unboxing and setup you’ll have to do. These tasks and simple though and include:
- Unbox the vacuum and remove all packaging.
- Install spinning brushes.
- Install HEPA filter.
How does it navigate?
Like most other robot vacuums, navigation is pretty self-directing on the Coredy R3500.
It doesn’t have any mapping technology or on-board camera, but it still does a pretty good job of cleaning the space.
Instead of “seeing” where it is going, it simply uses a “bump and continue” approach, lightly bumping into obstacles and then continuing into a different part of the room.

Removing and Emptying the Dustbin
To remove the dust bin, pinch down on the latch located along the perimeter of the vacuum and pull the dustbin out, away from the body of the vacuum.
From there, you can open up the dustbin by squeezing the two orange tabs on the top of the dustbin and pivoting it away from the body of the dust bin.
When it’s time to clean the HEPA filter, this is also where you can do that as well.
Coredy R3500 Maintenance
Maintenance on the Coredy R3500 is simple and low cost.
Here’s a short list of the items you’ll need to take care of to keep your Coredy running smoothly:
- Wash the filter / replace as needed
- Clear brushroll from tangles
- Empty dustbin
You can wash the HEPA filter with regular cold water and allow it to air dry. Generally, it takes a solid 24 hours for these types of filters to air dry enough to be reinstalled into the vacuum.

Is the Coredy R3500 a good value?
All things considered, I would say that the Coredy is a pretty solid value. It has a nice collection of features and the remote control is pretty handy.
It also has a long run time (up to 120 minutes) which helps to make up for the fact that it doesn’t have Recharge & Resume functions or digital mapping like other advanced models.
Cleaning performance was decent, although it definitely performed better on hardwood floors.
If you don’t mind the random navigation of the Coredy R3500, it is certainly a solid option worth considering.

Should You Buy the Coredy R3500?
Still wondering if this robot vacuum is a good choice for you and your home? Well, at the end of the day, it depends on a few factors.
I would recommend the Coredy R3500 if you’re looking for the following in a robot vacuum:
- Want a long run time: The Coredy R3500 can run for up to 120 minutes which should be more than enough time for the majority of cleaning jobs.
- Don’t need digital mapping: More and more robot vacuums are coming out with advanced digital mapping and wifi-integration. This can make it easier for your vacuum to navigate and for you to see where it has been. Of course, if you don’t need this feature, you can generally save a few bucks, as is the case with the Coredy R3500.
- Want an XL dust bin: This robot vacuum can hold up to 550 mL of debris in the XL dust bin. Translated into cups, that’s about 2.3 cups of dry debris.
- Want a budget friendly robot: The R3500 is priced in a sweet spot below many other robot vacuums on the market. True, it doesn’t have all the bells and whistles, but performance is still pretty good considering the price point.

Budget-Friendly, Fair Performance
- Design - 92%92%
- Performance - 82%82%
- Quality - 90%90%
- Usability - 92%92%
- Value - 90%90%
The Coredy R3500 is a budget-friendly robot vacuum with basic features. It was okay in our performance tests, removing 82% of total debris. It’s greatest struggle was on low and high pile carpet, where it only removed 77% (not bad for high carpet, but mediocre for low carpet). Nevertheless, given the price point, it’s still a good value and a good option if you’re looking for a basic vacuum bot.
