Coredy are an up-and-coming manufacturer of robot vacuums, positioning themselves at the budget end of the market with their R-series.

The devices stack up well against other cheap robot vacuum cleaners such as the Eufy. In this review, I’ll take a look at the R750 which is their most feature-heavy robot vacuum.

Quick Summary

The Coredy R750 is one of the top robot vacuum cleaners in the budget category. It performs well on both low and medium-pile carpets, often tackling thicker rugs with ease too. It has 2,000pA of suction power and a 500ml dust bin which are both well above average for the price.

It doesn’t map your home, however, the random path navigation provides near-perfect coverage of larger rooms and decent coverage of smaller rooms. It does have mopping capability but this isn’t a stand-out feature for the reasons I’ll discuss below.

It’s the only device in Coredy’s range to include Wi-Fi so that you can control it via the app and activate it with Alexa or Google Home, albeit only using basic commands.

I recommend this device to anyone looking for a cheap robot vacuum to keep on top of dirt in between regular vacuuming. If app control isn’t essential to you, it might be worth considering the lower-priced Coredy R650 which has a better price-to-features ratio.

If you want more advanced features such as mapping your home and room-by-room cleaning schedules, you’ll need a mid-range vacuum such as the Neato D7 or Roomba 960.

Here are the pros and cons of the Coredy R750:

Suitable for both low and high pile carpets
Boundary tape included for creating no-go zones
Control via app or using Alexa/Google Home (although voice commands are very basic)
Low maintenance as there is no roller brush

Mopping ability is less than impressive

Full Review

The Coredy R750 is Coredy’s most-encompassing robot vacuum, although compared to the rest of the market it’s still considered a budget device.

In this review, I’ll run through the key features of the R750 and take a look at how it fares for navigation and cleaning performance.

What’s Included?

Here is what will be included in the box:

  • Coredy R750 robot vacuum
  • 2 x 2m (6’6ft) magnetic boundary strips
  • 4 x side brushes
  • Spare HEPA filter
  • Remote control (with batteries included)
  • Charging dock with AC power adapter
  • Cleaning tool
  • Owner’s manual

Features Overview

As with all Coredy robot vacuums, the R750 still has a low profile that comes in at just 7.2cm tall. This means it can fit under most furniture in your home. It has a standard circular design for a robot vacuum with suspended wheels that can climb over thresholds up to 15mm, about the same as Roomba.

It has the largest battery out of all the Coredy products with a 3200 mAh capacity (compared to 2,600 mAh in the rest of the range), however with more suction power, its run time is still similar at 120 minutes which is enough for most small to medium homes.

The R750 has Wi-Fi connectivity which allows you to connect it to the Coredy app for controlling it. This allows you to change schedules, set cleaning modes, and monitor your device. You can also connect the app to Alexa or Google Home for voice control, however, it is limited to basic commands such as start and stop.

The Coredy app is essentially a white label version of the Smart Life app so you could use this instead of having a separate app for your vacuum.

There is still a traditional remote control included which is also capable of adjusting all the settings if you’d rather use this.


As you’d expect from a budget robot vacuum, it doesn’t use smart navigation or floor mapping, instead, it uses random path navigation which bounces around your home until it predicts that the entire floor has been covered.

Whilst this takes longer than smart navigation robots, you’ll still get near-perfect coverage of larger rooms, although the algorithm isn’t quite as good when it comes to smaller rooms so it may miss a few spots on each cycle.

You can set no-go zones using the included magnetic boundary strips. This is ideal if you have delicate objects or if there are certain areas where the vacuum frequently gets stuck such as under a bed or on some cables. The R750 comes with 2 x 2m strips and you can purchase extra strips at £30 for 2m.

You do not need to place strips at the top of your stairs as the robot also has built-in cliff sensors to detect and avoid large drops.

The lack of any mapping means you cannot see a floor plan in the app or schedule cleaning on a room-by-room basis like some of the best robot vacuums on the market.

Cleaning Performance

The R750 provides the best cleaning performance in the Coredy range, which shouldn’t be a surprise. It has suction power of 2,000 pascals (pA) which is slightly above average for its price.

The vacuum works well on both low and medium-pile carpets as well as hard floors, it also manages to navigate over thicker rugs providing there aren’t any awkward tassels.

The R750 doesn’t provide a perfect deep clean so won’t replace an upright vacuum altogether, however, it will certainly help keep the place looking spick and span in between vacuuming.

It has a removable, washable HEPA filter built-in, this is great for allergy sufferers as it traps tiny dust particles rather than releasing them into the air.

The Coredy has several different cleaning modes:

  • Auto mode – The main cleaning mode that will move around your home, adjusting the suction power as it encounters carpet and hard floor.
  • Edge mode – Use this mode if the edges of your room need an extra once-over.
  • Small room – A shorter 30-minute cleaning schedule.
  • Spot clean mode – Ideal when you’ve made a mess and need the Coredy to sort it out. The vacuum will spiral out from the spot you place it.
  • Max mode – This switch toggles the maximum suction power of 2,000pA.
  • Schedule mode – If you’ve set cleaning schedules in the app or with the remote control, use this mode to enable these.
  • Park mode – Send the vacuum back to its charging base

When on auto cleaning mode, the Coredy has a feature called Boost Intellect. This can detect when the vacuum has transitioned from carpet to hard floor and adjust the suction power accordingly.

Not only does this conserve power, but prevents lighter debris from being scattered as much.

Mopping Performance

If you’ve read my Coredy R550 review, you’ll know that I’m not a huge fan of their mopping feature and the same applies to the R750.

The R750 cannot switch between vacuuming and mopping by itself as it requires you to remove the dust bin and replace it with a water tank. At this point, you’ll also need to set boundaries to prevent the vacuum from lurking across onto the carpet.

The electric water pump on the mop pad is a welcome addition to control the water flow, however, the lack of any pressure on the pad means the pad just glides across the surface. This might be good for picking up dust, but it’s not going to remove any spillages so you may as well just stick to vacuuming.

You should also be aware that the 300ml water tank and mopping pad aren’t included with the R750 and should be purchased separately if you wish to use this feature.


The 500ml dust bin is a very decent size and will allow the vacuum to complete several cleaning cycles before it requires emptying in a medium-sized home. Once full, the dust bin features their newer single button clip which makes it very simple to empty.

As far as bristle brushes go, the R750 tackles hair quite well, especially compared to the Eufy. You will still need to remove tangled hairs now and again, but the new style roller brush makes this very quick to do. If you have pets, I would recommend looking at a Roomba as their dual rubber rollers tend to work much better with hair.

You’ll also have to wash the HEPA filter, but it comes with a spare to use in the meantime. There are also spare front brushes included which will need replacing from time to time.
