Best robot vacuum 2021 – for pet hair, carpets, and even mop functions

Hands-free cleaning really does become a reality when you buy the best robot vacuum. Many robot vacuums come with app compatibility and smart scheduling, so you don’t even need to be at home to achieve those spotless floors you’ve been slaving over with your upright vacuum. We’ve reviewed top robot vacuums from iRobot, Dyson, Ecovacs, Roborock, Proscenic and Roomba to bring you our complete list of the best robot vacuums you can buy.

There was a time when robot vacuums were a bit of a gimmick, with tiny battery lives and the propensity to throw themselves down the stairs or get stuck on your bath mat. Now though, they’ve proven themselves to be one of the best investments you can make when it comes to cleaning your home. Not only can you buy some of the best robot vacuums for under £200 (sometimes less, if there’s a good sale on) but you can also make the most of smart home mapping, mopping attachments, and battery life for a couple of hours, or more!

Should I buy a robot vacuum?

Anyone who has ever paid for a cleaner will know the joy of returning home to a spotless house. Even the most hi-tech of robotic vacuums can’t yet compete with that just-polished smell. But they can keep on top of the daily once-around. And all without you lifting a finger. Sure, we all know people who manage to vacuum virtually every day. But if you’re busy working and hate the idea of losing free time to chores, a robotic vacuum could be for you. Especially if you have pets.

We’re not suggesting they’re perfect by any means. A shoe lace, lump of Lego, or even rug can bring your robot underling to a premature stop. They work best on large open-plan houses on one level (like the typical American home). Therefore they may not be right for your small higgledy cottage. What we do know is, whatever makes the cleaning easier is well worth testing!

Best robot vacuums 2021

1. Proscenic M7 Pro

Best robot vacuum overall

Dimensions: ‎34.67 x 34.67 x 9.65cm
Dust bin:
0.4 litres
App, on-board
Reasons to buy:
Scheduling and the option of self-emptying
Reasons to avoid:
Dust collector costs extra

Let’s get the disappointment out of the way first, because the Proscenic M7 Pro doesn’t have its intelligent dust collector included. You’ll need to buy it separately, but it is nice to have the option of not emptying by hand after every use. In testing we enjoyed how easy it was to empty the Proscenic M7 Pro by hand and how easy it was to control on the app. You can set zones and customise cleaning between each one. There’s also the option of scheduled cleaning, which is ideal for those who are out of the house a lot and like to come home to a squeaky clean space.

There’s a brush on each side of the Proscenic M7 Pro which can sweep the surrounding area as it works. There are a total of 24 sensors included, meaning it won’t drop down the stairs or bump into fragile items while on its cleaning route. In particular, it did an excellent job of picking up pet hair thanks to the powerful suction.

Smart options are lacking but it can be paired to a smart speaker and instructed to start and stop cleaning as and when you desire. Not the most high-tech of options, but it covers the basics well. For the price, it’s the best robot vacuum.

2. Ecovacs Deebot N79S

Best budget-friendly robot vacuum

Dimensions: ‎33 x 33 x 7.8 cm
Dust bin:
App, on-board
Reasons to buy:
Reasonably price and great performance
Reasons to avoid:
The brush is prone to tangling

An Amazon favourite due to the low cost and easy use, we were impressed by just how powerful the Ecovacs Deebot N79S is on both hardwood and carpet. It’s got a Wide Reach bristle on either side of the front of the vacuum, both of which do an excellent job of sweeping debris in the path of the vacuum as it goes around the room. Its battery holds true to the 100-minute battery life promised by Ecovacs, but we did find that after about six months of use this had depleted to around 45 minutes. Still, that’s above average for many robot vacuums.

Not everyone will be drawn to a robot vacuum that requires lots of complicated controls and syncing to a phone, and one of the best things about the Ecovacs Deebot N79S is that you can simply press a button on the top of the machine and off it goes in Auto mode. Unlike some smarter vacuums such as the Roborock S6 it does move around more randomly instead of mapping a clear path around the room, but keep in mind that it does so for only a fraction of the price. Other modes include spot cleaning and edge mode, that targets skirting boards and corners very well.

Suction is powerful and the bin is large. The issues we encountered weren’t unique to the Ecovacs Deebot N79S. For example, the side bristles can get tangled easily if (well, when) they encounter long hair. When it comes to the top of the stairs it does detect an imminent drop, but we found that we needed to rescue it from the cliff before it would continue cleaning, despite the claim that it does this automatically.

Ideal Home rating: 4 out of 5 stars 

3. Roborock S6

Best robot vacuum and mop combo

Dimensions: ‎35 x 35.3 x 9.6 cm
App, on-board
Reasons to buy:
Mopping power and smart mapping
Reasons to avoid:
It’s a hefty4kg

While it’s designed to be one of the best robot vacuums, the Roborock S6 has an optional mop attachment that works simply by filling up the water container. It’s great on hardwood floors and leaves a relatively dry trail while still picking up superficial dirt. It’s no stand-in for an actual mop because there’s no suds or antibacterial cleaning solution involved, but for a tougher clean on laminate and tile we found it did a perfectly good job.

Onto the vacuuming, which really is the star of the show, the Roborock S6 is incredibly smart. It automatically maps out your space and figures out the smartest way to clean, meaning it tracks more of a zig-zag across your room than a random dodgem route; something we found with less smart robot vacuums. The vacuum also scans the room using the LiDAR navigation on top of the machine. Other features we enjoyed included automatic recharging and the rubber bristles that aren’t prone to tangling and can accurately detect barriers and move dirt into the path of the vacuum.

If you’re looking for the best robot vacuum and mop combination it’s a smart pick, and not the most expensive option in our guide.

4. iRobot Roomba 980

Best robot vacuum for total performance


Dimensions: ‎50dia x H91mm
App and on-board
Reasons to buy:
Consistent cleaning
Reasons to avoid: The docking system is a faff

iRobot, the company behind Roomba, actually started out making bomb disposal robots for the American military. The company has been selling robotic vacuums in the US for decades. The Roomba 980 is their top-of-the-range Wi-Fi connected design that costs less than the Dyson. In our opinion, it outperforms it.

The 350dia x H91mm lozenge can sneak under all but the lowest sofa, detects when it moves from hard floors to rugs and carpet. It boosts the motor speed for better cleaning results. It has a clever twin rubber brush bar. This is easy to clean and untangle and seriously good at picking up pet hair. The brush bars don’t extend right to the edge of the vacuum. However, the two spinning brushes sweep dust into the bars, so it can clean right up to the skirting boards.

It comes with two battery powered digital fencing devices that prevent the Roomba going where it shouldn’t. Away from a tangle of wires, or outside onto the decking for instance. But we’ve not found much of a need for them. It’s excellent across all sorts of terrain. It can climb onto thick piled rugs and hasn’t fallen down stairs once.

While not as simple to empty as the Dyson, the 980 has a HEPA filter to reduce allergens escaping back into the room. The consistency of the cleaning is the best we’ve come across. That’s both in terms of the amount of dust it picks up, and how well it navigates around the room. We rarely come home to find it tangled or trapped, just docked and recharging.

One word on the docking system though. Irritatingly, it can only be plugged in from one side, which limits where you can position it. We resorted to using Blu-Tack to keep it in the right position. It was a struggle to rest it flush against a wall.

5. Eufy BoostIQ RoboVac 11S

Best quiet robot vacuum

eufy by Anker, BoostIQ RoboVac 11S

Dimensions: ‎32.5 x 32.5 x 7.25 cm
Dust bin:
0.6 litres
Reasons to buy:
It’s quiet and affordable
Reasons to avoid:
You can’t pair it with an app

Robot vacuums are pretty smart, but that doesn’t mean you need to get one with all the bells and whistles. If you’re a bit scared of setting up new apps, or you don’t get along with Alexa, the Eufy BoostIQ RoboVac 11S could be a good choice for you.

It has a good old-fashioned remote control that allows you to select a cleaning style (spot clean, edge clean etc) and how deep you would like your clean to be. The vacuum also automatically adjusts to carpets, which means you’ll get custom cleaning no matter what room it’s in.

One other thing we love is the size. It’s only 7.25 cm tall, so plenty small enough to reach under the sofa. The Eufy BoostIQ RoboVac 11S is quiet, too. It reaches only 55bD when testing.

6. Dyson 360 Heurist

Best robot vacuum for reliability

Dimensions: ‎240 x 230mm
Dust bin:
0.33 litres
App and on-board
Reasons to buy:
Excellent suction and easy to empty
Reasons to avoid: The dust bin is tiny and it’s prone to getting stuck

Instantly recognisable as a Dyson product, the Dyson 360 Heurist is gorgeous. Well made, it has the same feeling of dependability (and usability) as their other vacuum cleaners. It might only measure 240 x 230mm, but it boasts of having ‘twice the suction of any other robot vacuum’. It also has the ability to look 360° around a room. And it has a high-quality carbon fibre brush bar (like the one found on the excellent Dyson V8 Handheld).

With one simple button – and a comprehensive smartphone app – it’s a breeze to use. Easy to set timers, it’ll even draw you a map to show how much cleaning it does while you’re at work. It isn’t the simplest device to link to your Wi-Fi, requiring long passwords and a fair amount of faffing. The transparent dust collector is easy to empty without creating a mess. The filters can be rinsed under the tap and the docking station sits flush with the wall.

The cord can be plugged in either on the right or left hand, depending on the nearest socket is. Watching the 360 Eye work is slow going but give it time – you’re at work after all. The excellent mapping cameras and sensors will cover the open ground with ease. The short 45min battery life and slow recharge rate mean it took over three hours to cover a large living room.

The small size means it can get through chair legs more easily than the rest. At 12cm tall it might struggle under very low sofas, but we didn’t have an issue. The first time we used it, we were embarrassed by how much dust and dirt it collected.

It was hugely impressive, with the living room looking and feeling cleaner. Over time though, we did get frustrated by its tendency to get stuck on the fireplace hearth (The Roomba or Miele had no issues with this). It became a bit of a joke as to where Dyson would be when we got home.

How to buy the best robot vacuum for you

1. How does a robotic vacuum cleaner work?

Basic robotic cleaners generally clean in straight lines, running until they bump into something. They turn around and head back the way they came. Some work by spinning in a spiral from the middle of the room until the hit the edges. However, the latest designs boast NASA style sensor. This helps them map out any room and prevent them toppling down the stairs.

All robot vacuums have drop sensors to avoid falling, and most have bump sensor in case the do run into things. A combination of cameras and even lasers help guide the top of the range designs. These robots track what has been cleaned and what is left to clean until they’ve finished that particular section of your home. It might look like they work randomly, but trust us, it’s anything but!

Some can also tell if they change surfaces – from carpet to hard floor for instance. They can decrease motor power in that instance. Some can even sense if there’s more dirt and pass over the area more frequently.

2. How much should I spend on a robot vacuum cleaner?

A good robot vacuum isn’t cheap, and you should budget around £500. Anything less and you’re looking at more of an automated floor sweeper than intelligent appliance. Our best buys cost around £700 which is a lot, especially given you’ll still need to occasionally run around with a regular cleaner, but if you’re a pet owner sick of hair balls blowing across the room, the daily clean of a robotic vacuum will be worth every penny.

3. How well does a robot vacuum really clean?

We were horrified by how much dust, dirt and pet hair was collected by the robot vacuums. Remember to pick obstacles off the floor before leaving the house. This way you will come back to a much cleaner floors. And the beauty is, it will clean every day, without complaining. Admittedly the quality of cleaning is dependent on the vacuum’s ability to clean unobstructed.

If you have stuff everywhere you should expect it to get stuck from time to time. Also, it can’t get right into the corners, no matter what the blurb on the box says. It also can’t climb stairs. So if you want to clean bedrooms or bathrooms you’ll need to take it up and turn it on. If you ask us, it’s still better than doing it yourself.

What features should I look for when choosing a robot vacuum cleaner?

  1. Timers: An absolute must, there’s little point having a robot cleaner if it can’t do the housework while you’re not there. The easiest to program are the connected app-controlled models, but even basic design will have digital clock style timers.
  2. App control: If your robot vacuum comes with a smartphone app you’ll be able to control it remotely. Turn on from work for instance if you’ve got an unexpected visit from the in-laws. Plus, you can now track your vacuum’s progress and see how much of the room it has cleaned. This is useful to see if there’s areas the robot can’t access.
  3. Filters: The vast majority of cleaners have built-in air filters to trap unwanted particles and stop them being pumped back into the room. Look for washable designs for longevity, although all brands sell replacements.
  4. Docking station: All vacuums need recharging at some stage and being able to take themselves home for a refuel is a huge bonus. However, battery life isn’t that significant assuming you’re in no rush to get the floors cleaned. If you’re out at work, you can let the cleaner work all day – charging up as it goes. Positioning the dock however can be an issue, so check if you have a well-located spot against a wall, in close proximity to a plug.

Robot vacuum cleaners aren’t perfect yet, but you can help them perform better with these easy tips:

1. Tidy up

Even the most hi-tech sensors can’t navigate around piles of Lego or dirty laundry, so to give the vacuum the best chance of a success, have a quick tidy before you leave.

2. Don’t get rid of the old vacuum

Robots can’t clean stairs, curtains or upholstery (yet!).  Therefore you will still need a proper vacuum, or a decent cordless handheld with a nozzle and crevice attachments.

3. Use the timers

Robot vacuums work best if they clean every day. Learn how to use the schedule and set it to clean when you know you’ll be out the house.

4. Clean it regularly

As with a regular vacuum, make sure you clean the filters regularly. Get rid of any tangles as soon as you discover them.
