Coredy Smart Robot R750 Vacuum Mopper and Sweeper Review

The Coredy Smart Robot R750 Vacuum Mopper and Sweeper is among the highest-rated home robot cleaners. Is it worth buying? Here's an in-depth review of the R750
Coredy Smart Robot R750 Vacuum Mopper and Sweeper

The Coredy Smart Robot R750 Vacuum Mopper and Sweeper #amazon ad is a super-thin, only 2.7 inch, vacuum that can clean a hard floor and then move seamlessly on to carpets where it will automatically increase suction up to 2000Pa.

When you open the lid of the box, you’ll see printed in very large print on the inside of the lid of the box a “Quick Start Guide” showing five clear and easy-to-follow steps to get this robot up-and-running along with contact information for customer service.

Once you’re all set up, this lean, mean dust and crumb fighting robot vacuum machine will take ownership of your home’s hard-floors, sucking up the finest particles of dirt along with beach sand, popcorn kernels and those long-ago dropped peanut shells.

It’s a pet-owner’s dream when it comes to some medium-pile carpets with fringes. It will roll over and onto the carpet, increasing its suction to suck out any and all pet hairs along with dirt and dust. Note: the cat and dog may want to move, so it can clean their favorite sleeping spots.

With a water tank in place of the normal dirt bin holder, you’ll be able to give your floors a nice wipe-up of those areas that get a lot of foot traffic.

Two sturdy, durable driving wheels move this smart robot on its path to cleaning. The universal wheel between the two Side Brushes allows this vacuum robot to bounce back, turn, pivot, and move in any horizontal direction, to get at every corner of the room for cleaning. The wheels also allow the robot to roll onto carpets as well as move around on carpets.

Towards the back end is the Main Brush with a Brush Guard. The brush is made so that it will pick up fine dirt, large particles, cat and dog hairs without the hairs getting tangled in the brush. All of this is dumped into a 500 ml (16.9 oz) dust bin that can be easily removed, cleaned, and slid back into place.

One nifty-cool feature is that the Coredy Smart Robot has built in Smart Protection that will prevent the robot from plunging down stairs and falling off edges. This anti-collision technology also helps evading obstacles. It’s fun to watch.

Let’s dive more into this review and discover more about this amazing home floor-cleaning robot machine.

Floor Types and Carpets

The Coredy robot is intended for sealed floors like:

  • Hardwood floors
  • Tile and Ceramic Tile
  • Linoleum
  • Marble and Marble floors with granite drops
  • Vinyl and Vinyl Laminate
  • Laminated

Some reviewers have mentioned that the R750 moves right onto a rug with fringes. In addition, some folks have had success with the robot vacuuming a high-pile carpet.
Note: May not work with dark carpets, especially some high-pile carpets.

MAX Cleaning Suction Control

The vacuum starts cleaning at 800Pa, the default setting. However, pressing the “MAX” button on the remote will boost the suction to 2000Pa.

NOTE: How strong is 2000Pa? The Coredy R750 has enough suction to pick up AA batteries off the floor. That’s a lot of suction power!

Support Boost Intellect Technology

When the robot vacuum rolls on to a carpet it will automatically increase suction to 1200Pa. Once it rolls off the carpet, it goes back to normal suction, 800Pa.

Flexible Cleaning Options

The Coredy R750 has five options for cleaning your entire home. If at anytime the battery gets low during a cleaning cycle it will return to the Charging Dock to get recharged.
Note: There is no memory with this model. It will not pickup where it left off after being recharged.

The flexible cleaning options are:

1-Auto Cleaning

The robot will clean the floors in a random pattern until the floor is thoroughly cleaned.

From time-to-time it will touch up around the edges of chair legs and other furniture as well as clean the edges of the room.

It will continue to clean until the entire part of your home is cleaned at which point the good robot will return to the Charging Dock. However, if the battery gets low before the complete cleaning is done, it will return to the Charging Dock for recharging.

2-Spot Cleaning

When Spot Cleaning in selected the Coredy Robot will seriously clean a localized area by spiraling outward to about 3 feet (1 meter) diameter circle and then spiral inward to where it started. The robot will also boost the vacuum power when Spot Cleaning creating more suction and a deeper cleaning of that localized area.

VIDEO: Spot Cleaning

3-Edge Cleaning

Once the open floor spaces have been cleaned the smart little robot uses Edge Clean to get at those hard-to-clean edges under the counters, in the corners and around the furniture legs. You have the option to start a quicker edge cleaning by pressing the “Edge” button on the Remote Control.

VIDEO: Edge Cleaning

4-Single Room Cleaning

This is a nice option if you want a quick clean for a specific room or you have a small room. If there’s room for the robot to move around in your bathroom it can clean there too.

The R750 robot will work vacuuming a single room and stop after 30 minutes. The robot will clean the room in a random path. Pressing the little ‘House” button on the Remote Control will start the Single Room Cleaning.

IMPORTANT: Make sure the doors are closed so you ensure that this robot does wander off into another room.

5-Manual Cleaning

Finally, the robot can clean a specific area by using the directional buttons on the remote control.

  • Move forward
  • Move backward
  • Turn left
  • Turn right

Using Boundary Strips

If there are any places where you don’t want the Coredy R750 to go you can use boundary strips.

Measure the area you want to create a boundary around, cut the strips to create the boundary. When the smart robot comes to the boundary strip it will turn away and head in another direction. It will continue to head in a different direction every time it comes to a boundary strip until the cleaning cycle is finished.

Use the boundary strip to keep the robot off a special carpet, away from multi outlet extension cords, easy-to-tip-over stands, and the stairs of an outdoor balcony or patio and anyplace else you want to keep out-of-bounds for Coredy.

Intelligent Robot Mop Cleaning System

Coredy R750 has the ability to do either wet or dry mopping with the included washable and reusable microfiber cloth. The mop cloth can last from 3 to 6 months before changing or when it looks visibly worn. They can be either hand or machined washed.

The .3 L (10 oz) water tanks take the place of the dust bin.

The mopping feature is optimized for regular dirt and dirty shoe or paw prints. It’s not designed for heavy spills or dog saliva or pet accidents, ie., missing the toilet time.

The mopping system has an intelligent electronic-controlled water pump, that automatically controls the water flow to start and stop during the mopping cycle. It automatically monitors the water level control by sensing the dryness and humidity of the floor without spillage.

Four Mop Cleaning Modes

The four mop cleaning modes work in a similar fashion as the vacuum modes. Both the remote and Coredy Robot App can select the desired cleaning mode to help you get the most optimal mop cleaning for your home.

  1. Auto (default): can mop 150² sq. m. (1615 sq. ft.)
  2. Random: Mops in a back-and-forth random path.
  3. Spot: works in an outward circular motion to about a 3 ft diameter and then circles back in.
  4. Edge: Focuses on cleaning the edges of a room.

VIDEO: Mop-Spot Cleaning

Mopping Level Selection

The Coredy Robot App, not the Remote Controller, allows you to select the water flow levels for mopping in the Auto Mode:
Low – Runtime of 150 mins
Medium – Runtime of 120 mins
High – Runtime of 90 mins

Note: If you want to dry sweep/mop the floor don’t fill the water tank.

When mop cleaning the robot will not be able to detect nor avoid carpets. It’s best to use the Boundary Strips to prevent the robot from mopping the carpets.

Some reviewers mention if you want to mix in some floor cleaner, it’s best to dilute way down so the mop will not leave any streaks. Also, it’s important that the water tank is thoroughly cleaned when using any kind of cleaning solution. Other users recommend using only warm water.

There’s a snap on/off plug at the bottom of the water tank that makes it easy to empty the remaining water when done mopping. The tank can be easily filled from any kitchen faucet.

Consumer Ratings

The Coredy Smart Robot has continuously gotten high reviews for its ability to clean a variety of hard floors and carpets. Most pet owners are impressed how well the robot cleans the floor and carpets of pet hairs without getting the hairs tangled. In the even the hairs did get tangled the comb accessory easily cleans the brush.

The mopping is not as good as hand mopping. It’s more for adding an extra bit of cleanliness.

My Overall Review of the Coredy Smart Robot R750

The sturdiness of this robot as well as it’s integration with the Coredy Robot App make this smart robot the go-to cleaner of a home.

The price is competitive to other models. The price is cheaper than the price offered at the manufacture’s site.

This model would be a good fit for an apartment, small or large home that has a mix of hard floors and carpets. It would not be good if you have thick-pile carpets that are dark.

It’s a nice feature having the “Quick Start Guide” on the inside of the box cover. If you can trust that it’s doing it’s job with it’s random movements then you will not be disappointed. However, this model will not map out the rooms.

Connecting the robot to the Coredy Robot App adds more monitoring features, like battery life, accessory life, as well as connecting to Alexa and Google Assistant. However, it’s not essential. The Remote Control allows you to select the cleaning mode, schedule, select mopping level, start/stop, mop/vacuum cleaning, control direction (eg. right, left), and select select MAX suction power.

And finally, it’s easy to keep this robot running at peak performance following the Regular Robot Care outlined in the manual.
