Best robot vacuum 2022: Clean up with the 8 most effective robot vacuums

Advertisement

Sick of doing the weekly hoovering? Why not let a robot vacuum cleaner give you a helping hand?

With technology progressing rapidly in recent years, the humble robot vacuum cleaner is now the best way to keep your house clean with minimal effort. You no longer need to push a heavy vacuum around your home to keep your floors in pristine condition.

Crucially, robot vacuum cleaners are no longer the expensive pieces of home cleaning tech they used to be. You can now pick up a reliable robot vacuum cleaner for less than £200, although there are still some high-priced options to choose from if you prefer a robot vacuum cleaner with all the bells and whistles. If you’re after an easy and effort-free way to keep your floors clean, buying one of these robotic helpers could be one of the best investments you ever make.

Thanks to the use of built-in cameras and a variety of sensors, robot vacuum cleaners will find their way around your home with minimal fuss – and the more expensive models come with different cleaning modes and advanced features such as the ability to produce maps of where they've cleaned and for how long.

However, with such a wide variety of models to choose from – at varying prices – it can be tricky to choose which robot vacuum cleaner suits your needs and budget. Here at Expert Reviews, we’ve tested all the latest models, to prevent any guesswork on your part when you buy. These are the only robot vacuum cleaners you need to consider buying in 2022.

How to choose the best robot vacuum cleaner for you

How well do they deal with household obstacles?

All robot vacuums employ bumpers and sensors to help them navigate their way around your home and to prevent them coming to grief by falling down the stairs. But some are more efficient at finding their way around than others.

The cheaper versions run to a random cleaning pattern and bump around your rooms blindly, cleaning as they go. This works up to a point but it can take a while for these types of vacuum to finish cleaning a room and, although they do their best to cover all the floor, they often miss spots here and there.

The more expensive robots employ cameras and advanced laser sensors to map out their surroundings first before tackling each room. This means they can work out the most efficient route before getting started and don’t need to cover the same spot twice, as can happen with robot without these sensors.

Even then, advanced sensors can only go so far. A big problem with robot vacuums is that, no matter how good they are at mapping out their surroundings, they often get beached on low-lying furniture and stuck on stray cables.

The best way to avoid this is to keep your floors clear of such items, but in some cases that isn’t possible, which is where you want a robot that comes with the ability to set virtual no-go zones in the accompanying app. That way you can instruct your robot to avoid the places you don’t want it to go near.

Which robot vacuums give the best cleaning performance?

Although most robot vacuums look the same from the outside, they deliver vastly different levels of cleaning performance. And this is affected by a number of different factors. Probably the most important aspect is brush configuration.

Our favourite robot vacuums have brushes that span the full width of the unit, allowing them to clean right along the edges of your room and into the corners. Alas, these aren’t particularly common and most stick with the popular disc-shape, with the main brush situated between the wheels and a couple of less effective spinning brushes in the “corners” of the vacuum to drag dust into the mouth of the vacuum.

Next, you need to consider suction power. Typically expressed in Pa (pascals), this is a measurement of how powerful the motor is inside a robot vacuum. A good number to look for here is around 2,000Pa or above for an effective clean.

How we test

We test each robot vacuum cleaner by installing it in a typical domestic setting. The charging station is always placed in the same location, and the robot is given the same basic floorplan to clean, so we can see how elements such as navigation and speed compare between every robot we review. It’s a challenging floor plan that challenges even the smartest robot, with plenty of corners, tight spots, low furniture, surface changes and cable nests.

During testing each robot is connected to Wi-Fi and controlled through the supplied app, where available. We test all the features and functions available, including navigation to a second storey, to ensure robots can handle switching between multiple maps. If a robot has a self-emptying station or comes with a mop attachment, we test those too.

When it comes to analysing a robot’s cleaning capabilities, we test each robot using measured spillages of rice and flour. We send the robot to perform a spot clean of each spill on both carpet and hard floor, and measure the amount collected each time. This indicates how effective each robot is at gathering these problematic materials, and allows us to compare the results with every robot vacuum cleaner we’ve ever tested.

Is there anything else I should consider?

  • Bin capacity: Robot vacuums need emptying more frequently than a regular vacuum, but there’s still quite a variation in bin capacity from model to model. The largest you’ll see tend to be around 0.7 litres in size, but they can be as small as 0.4 litres. Some models have larger bins built into their base stations that they automatically empty into when charging, but these tend to be very expensive
  • Mop attachments: As robot vacuums become more popular, we’re seeing more manufacturers build in mopping features as a way to set their robots apart. These use a small water reservoir with a cleaning pad attached to the bottom that drags around the floor as the robot makes its way around your room. You’ll still need to use a proper mop to get stubborn stains off, though: a mopping robot is only good for cleaning up light dirt and dust from your hard floors.
  • Height: One thing robot vacuums are great at is cleaning below low-lying furniture, but some are considerably taller than others so it’s well worth checking out the dimensions before you buy to make sure it will fit where you want it to go.

The best robot vacuum cleaners to buy in 2022

1. Eufy RoboVac 15C Max: The best-value robot vacuum cleaner

Price: £250 | Buy now from Amazon

You might not have heard of Eufy, but don’t let that put you off: this superb RoboVac 15C Max is a solid choice if you’ve got £250 to spend.

The Eufy RoboVac 15C Max is the more fully featured version of our previous budget robot vacuum top pick, the RoboVac 30C. It costs a little more more – the RoboVac 30C has dropped in price since launch – but the 15C Max provides much more suction power than its predecessors. With 2,000Pa of suction, the 15C Max is very powerful considering its price but despite the extra power, it’s still impressively quiet regardless of which of the three settings you use (t has three cleaning settings: Standard, Boost IQ and Max).

Carpet areas will benefit from some of the more powerful settings, but we found the standard setting to be more than suitable for easy-cleaning hard flooring. Boost IQ adjusts the suction power automatically as the vacuum cleaner transitions between different types of flooring. The RoboVac 15C Max can also run up to 1hr 40mins on a single charge and is compatible with Alexa and Google Assistant for a fully hands-off approach to your daily cleaning.

It isn’t quite as feature-rich as some of the other robot vacuum cleaners on this list – it lacks infrared scanning and room-mapping – but at well under £300, the RoboVac 15C Max barely places a foot wrong and you’ll be hard pressed to find anything better at this price.

2. AEG RX9.2: The best all-round robot vacuum cleaner

Price: £554 | Buy now from John Lewis | Buy now from Amazon 

Best robot vacuum: AEG RX9.2

The AEG RX9.2 is unique among robot vacuum cleaners because it breaks free from the standard hockey puck circular design with a more triangular shape. It’s a stroke of genius, because it lets the corner brush reach all the way into the corners – an operation that is hampered by the curved edges of circular robots.

It uses a camera and lasers mounted on its front edge to weave its way around your furniture, carefully stopping in front of table and chair legs, and moving around them with minimal contact. This makes it a bit slower than robots with a more aggressive attitude to obstacles but your tables and chairs – and pets – will thank you for it.

The robot is controlled by an app, and we found its initial mapping a little fiddly to complete but we got there in the end. Once it’s all set up, however, the RX9.2 proved to be one of the best-performing robot vacuum cleaners we’ve tested to date.

Key specs – Size: 320 x 270 x 85mm; Weight: 2.5kg; Battery life: 40mins; Charge time: 2.5hrs; Bin capacity: 0.7l; Wi-Fi connectivity: Yes; Decibel volume: 75dB

3. Eufy RoboVac X8: The easiest to use robot vacuum cleaner

Price: £450 | Buy now from Amazon

Best robot vacuum: Eufy RoboVac X8

A good robot vacuum cleaner needs to be a good all-rounder: effective at picking dust and dirt off your floor but also supported by solid navigation and a good app. The Eufy RoboVac X8 lines up all these elements. It isn’t the best cleaner we’ve ever seen in terms of dealing with serious mess in a spot clean but it is a solid general cleaner, has a brilliant app and is excellent at mapping, which makes it easy to configure and use.

Its cameras and lasers build up a detailed map of your floor as it performs its initial clean. This is then saved by the smartphone app, so you can send the X8 to clean individual rooms and set virtual boundaries to cordon-off no-go areas. This simple and intuitive operation, accompanying an affordable and capable robot, makes for a compelling package that’s excellent value for money.

4. Dyson 360 Heurist: The best for a thorough clean

Price: £899 l Buy now from John Lewis

With twice the suction power of any other robot vacuum cleaner we’ve tested, the Dyson 360 Heurist may be the priciest vacuum on this list, but it’s the only one with a genuine claim to being the only one that could replace your standard upright cleaner. With the Heurist, Dyson has not only improved suction by a claimed 20% but has also introduced an LED lighting ring so the robot can navigate in dark rooms and developed an improved app that gives more control over the robot.

The design hasn’t changed much between generations; it’s still around the same size and shape as the previous model – the 360 Eye – and it even uses the same digital motor as before. Instead, the new Dyson 360 Heurist builds on the things that set Dyson’s last robot apart from the competition – tank tracks for climbing obstacles, a full-width brush bar for close-to-the-edge cleaning and a 360-degree camera for all-around vision. If you want a robot vacuum cleaner with all the perks, look no further.

Key specs Size: 2.3 x 2.4 x 12cm; Weight: 2.51kg; Battery life: 75mins; Charge time: 2.5hrs; Bin capacity: 0.5l; Wi-Fi connectivity: Yes

5. Eufy RoboVac 30C: Best budget robot vacuum cleaner

Price: £220 | Buy now from Amazon

The RoboVac 30C is another solid robot vacuum cleaner for the budget-conscious. It’s circular in shape and has a low profile so it can fit under furniture and clean the carpet under your bed, and it will recharge itself at its base when it runs low on battery power. With up to 100 minutes of cleaning per charge, though, it should be able to cope with even the largest of rooms before having to do that.

Other features include Alexa and Google Assistant support (so you can tell it to go clean via your Echo or Google Home speakers), a companion app so you can control it via your smartphone and a useful remote control that lets you direct operations when your phone isn’t handy.

With 1,500Pa of suction power, the Eufy RoboVac is pretty powerful for the money, and it’s reasonably quiet, too. If you’re looking to dip your toe in the water of automatic vacuum cleaning but don’t want to spend in the region of £500, this is the next best thing.

Key specs Size: 32.5 x 32.5 x 7.2cm; Weight: 2.7kg; Battery life: 1hr 40mins; Charge time: 3hrs; Bin capacity: 0.6l; Wi-Fi connectivity: Yes; Decibel volume: 55

6. Ecovacs Deebot Ozmo 920: Best value robot vacuum for features

Price: £400 | Buy now from Amazon

Best robot vacuum: Ecovacs Deebot Ozmo 920

Before you splash out £400 on a robot vacuum cleaner, there’s a laundry list of features you’ll want to tick off. Laser scanning is the priority, allowing the vacuum to map out its surroundings before proceeding to clean, methodical cleaning is another and room mapping with virtual no-go zones is essential. The Ecovacs Deebot Ozmo 920 has all of these things and doesn't cost the earth (relatively speaking).

It also includes a mopping function with a sizeable 240ml water tank and even allows you to adjust how much water is used remotely via the app. There’s automatic surface detection, so it can ramp up the suction power when travelling from hard floor to carpeted areas, and a large battery gives up to 1hr 50mins of cleaning per charge.

In our testing, we found it cleaned effectively and efficiently, without getting stuck in the usual places, and it’s pretty quiet, too. It’s a great all-rounder and, although suction and cleaning power can’t match the Dyson 360 Heurist, it is quicker and a lot cheaper.

Key specs – Size: 350 x 350 x 93mm; Weight: 2kg; Battery life: 1hr 50mins; Charge time: 4hrs; Bin capacity: 0.43l; Wi-Fi connectivity: Yes; Decibel volume: 66dB

7. iRobot Roomba j7: The best robot vacuum for pet owners

Price: £700 | Buy now from Amazon

One of the annoying things about robot vacuum cleaners is that you generally have to tidy up before you set them off. Encounters with charging cables, stray socks or, if you’re really unfortunate, pet poo, can cause them to get stuck or make more mess than they clean up. There’s not much point in setting an automatic schedule for your robot to clean if you’re prone to leaving stuff on the floor.

However, you don’t need to worry about such things with the iRobot Roomba j7. It isn’t going to tidy away your mess but it will give a wide berth to obstacles that could cause it problems. It still gets nice and close to furniture but won’t be phased by the odd dropped sock.

It’s also a proficient cleaner, with a two-roller system that does a good job of scooping up dirt and dust while avoiding hair tangles. If you want a robot that also empties itself, check out the Roomba j7+, which is the same robot but comes with a charging station that empties the collection bin after every clean.

Key specs – Size: 340 x 340 x 92mm; Weight: 3.3kg; Battery life: 1hr 15mins; Charge time: 2hrs; Bin capacity: 0.25l; Wi-Fi connectivity: Yes; Decibel volume: 55dB

8. Proscenic M8 Pro: The best value self-emptying robot vacuum

Price: £499 | Buy now from Amazon

There aren’t many robot vacuum cleaners that offer as many features as the Proscenic M8 Pro. It has the ability to both vacuum and mop your floor and it can empty itself into its self-emptying recharging station as well. Even more impressive is its price, which is several hundred pounds less than most other models that come with similar capabilities.

The M8 Pro navigates using LiDAR, so builds an accurate map of an area as it goes. This is fed into the smartphone app and can be used to control where the robot cleans and where it should avoid. It’s worth noting, however, that it can only save one map at a time, making it a bit of a pain to use on more than one storey of a household with multiple floors.

Key specs – Size: 350 x 350 x 98mm; Weight: 6.7kg; Battery life: 4hrs 10mins; Charge time: 4-6hrs; Bin capacity: 0.28l; Wi-Fi connectivity: Yes; Decibel volume: 68dB
