I first started reviewing robot vacuums six years ago, which means I've watched them progress from bumbling overpriced frisbees to genuine household helpers. While early robot vacuums often bumped their way around my living room, gobbling up wires and spreading messes in their wake, the smartest models you can buy in 2026 offer AI-driven obstacle avoidance, retractable mops that can scrub away dried-down dirt, and "all-in-one" stations that empty the dust, wash the pads with hot water, and even refill their own tanks.

In other words, if you've been holding off, I really think 2026 is the year to make the switch to robot vacuuming. And if it's been a few years since you've upgraded, the latest tech could seriously change your cleaning routine.

Reasons to avoid

-
Weaker on very deep carpets
-
App mapping can be frustrating
Buy it if:

✅ You want a true all-rounder: The Shark PowerDetect UV Reveal aced our tests with a 93.1 overall cleaning score —making it a strong pick for both vacuuming and mopping.
✅ Low-maintenance is a key consideration: With a bagless dustbin that lasts up to 60 days, most users rarely need to think about emptying the bin, which makes upkeep refreshingly simple.
✅ Spotless floors are a key consideration: The built-in UV light exposes stains and spills you might otherwise miss, which we found unexpectedly helpful for deep cleaning.

Don't buy it if:

❌ You have really deep carpets: In our carpet test, the Shark Reveal picked up just 55% of kitty litter — this was skewed by the abnormally deep carpets we tested on, but if your carpets are also deep, you might want to look for a stronger suction.
❌ A versatile app is a top priority: Editing the map in the app can be tedious and sometimes confusing.

The Shark PowerDetect UV Reveal stands out as our top pick for robot vacuums, with a 90% overall score in our controlled tests and incredibly strong performance in our real-world testing. It's the best on the market for most people.

Handling everyday debris and pet hair is where the Reveal truly excels. In our tests, it achieved a perfect 100 for pet hair removal. The integrated UV light made hidden stains, forgotten spills and dried-down dog dribble visible, something we tested didn't know he needed until it spotlighted a mess he’d missed under the couch.

Long-term maintenance is refreshingly simple. The 60-day bagless dustbin proved itself over weeks of use, with reviewer Jason noting that it was able to keep up seamlessly with his 1,300 square foot floorplan — the battery proving sufficient for cleans exceeding two hours. If you're dealing with a larger floorplan, it's up to the task.

While it's not the most premium or the best value option in this guide, we do think it's the best option for the average buyer. As the brand so often does, the Shark PowerDetect UV Reveal strikes a smart balance. Its mop pad isn't the most advanced on the market compared to the likes of the Dyson Spot+Scrub, but it does offer the self-cleaning and drying features we're seeing on flagship models in 2026. As for the UV-reveal light, that's a feature we've not seen before in our countless robot vacuum reviews.

There are trade-offs. While reviewer Jason caveated that his carpet is incredibly deep, the Shark's score of 55% in our kitty litter tests did significantly drag down its overall score. Annoyingly, Shark doesn't share the PA suction ratings of its robot vacuums, but the powerful Roborock Qrevo Curv 2 Pro offers an astonishing 20,000, and is our top pick for deep carpets.

The Shark PowerDetect UV Reveal is a great fit for buyers after reliable, whole-home cleaning with minimal upkeep. If you want a robot that covers all bases, at a price that feels reasonable, it's our top recommendation.

Best robot vacuum for pet hair

Specifications

Size: 15 x 18 x 19 inches
Power: 36,000 Pa
Mop type: Spinning pads
Dustbin capacity: 84 ounces
Dock dustbin: Self-emptying
Smart home compatibility: Alexa, Siri, Google Home

Reasons to buy

+
Powerful 36,000 Pa suction
+
Brush resists pet hair tangling
+
Smart obstacle detection & avoidance
+
Consistently removes embedded pet hair

Reasons to avoid

-
Mop missed spots in lab tests
-
An expensive pick
Buy it if:

✅ You struggle with daily pet shedding: If pet hair is a daily struggle, the Saros 20 reliably lifts fur from both carpets and hard floors, outperforming most rivals in our tests.
✅ Tangled hair brushes frustrate you: The Saros 20’s dual-tangle brush system means less hands-on maintenance, staying cleaner in homes with lots of shedding.
✅ Obstacle avoidance is a priority: The Saros 20 effectively dodges toys, bowls, and pet obstacles, so you can trust it to finish the job.

Don't buy it if:

❌ Spotless one-pass mopping is a must for you: The Saros 20’s mop often missed patches and left visible streaks in our lab tests—look elsewhere if mopping is a top priority.
❌ You're on a budget: While cheaper models can struggle on pet hair, there's no denying that the Saros 20 is a premium pick.

If you’re tired of battling pet hair stuck in your carpet or wrapped around your robot’s brush, the Roborock Saros 20 delivers a real solution. In our tests, its astonishing 36,000 Pa of suction power (the highest in this guide) made a noticeable difference in pulling up pet hair. Its dual-tangle brush design worked reliably to keep fur from winding around the roller, even after heavy use in a home with multiple pets.

The dual-tangle brush system isn’t just a spec; it shows up in daily cleaning. Over weeks of repeated sessions, we found the Saros 20 rarely needed manual brush clearing, and the vacuum consistently filled its bin with pet hair that other models left behind. Its suction remains strong on both carpets and bare floors, making it a good fit for households that constantly battle pet hair and dander.

For many pet owners, homes can often double as obstacle courses. The Saros 20 sensed errant toys and food bowls with impressive reliability, navigating around them to keep cleaning on track. In homes where pets are always underfoot, this level of obstacle avoidance takes the stress out of automated cleaning.

The one place the Saros 20 stumbles is mopping. In our trials, its mop often missed patches of dirt and left streaks behind. Buyers expecting a spotless mop finish will likely be disappointed and may need to rely on a separate mopping routine for best results. If mopping is a top priority, we suggest checking out the Dyson Spot+Scrub.

At its price point, the Saros 20 is a premium choice. Budget-focused buyers might turn to models like the Ecovacs Deebot N20 Pro, or the mid-priced Roborock QV 35S, although neither can match the Saros’s pet hair pickup or obstacle avoidance.

Best budget

Best robot vacuum for $200

Specifications

Size: 13.9 x 13.8 x 3.8 inches
Power: 8,000 Pa
Mop type: Removable pad
Dustbin capacity: 13.5 ounces
Dock dustbin: No
Smart home compatibility: Amazon Alexa, Google Assistant

Reasons to buy

+
Excellent value for the price
+
Dependable for daily cleaning
+
Quick setup and easy app controls
+
Better edge cleaning than most budget models

Reasons to avoid

-
Manual dustbin emptying required
-
Mopping is only for light jobs
-
Less suction than top-tier rivals
Buy it if:

✅ Affordable daily cleaning is your priority: The N20 Pro delivers reliable cleaning performance on everyday dust and debris, all at a very low price point. It's an affordable way to keep floors tidy without skimping on results.
✅ You have both carpets and hardwood: This robot vacuum keeps up with a variety of messes—pet hair, crumbs, and dust—on both carpets and hardwood, so you get reliable results throughout your home.
✅ Complicated app setups frustrate you: With app setup taking less than five minutes and intuitive controls for scheduling and cleaning modes, the N20 Pro is user-friendly from the start.

Don't buy it if:

❌ Hands-off bin emptying is a priority for you.: The N20 Pro requires you to empty its dustbin manually every few runs, so if you prefer a self-emptying model, you’ll need to spend more.
❌ Heavy-duty floor scrubbing is a must for you.: The N20 Pro’s mopping feature is basic—good for quick refreshes but not equipped for tough or sticky messes.

The Ecovacs Deebot N20 Pro is the top robot vacuum for under $200 we've tested. Combining a very low $199 price with impressively reliable cleaning on both carpet and hardwood floors, if you want a budget-friendly robot that still genuinely tackles daily dust and debris, the N20 Pro is an easy choice.

Getting started is straightforward. Reviewer Ashley had the N20 Pro mapped and running in minutes, with the app guiding each step clearly. The companion app isn’t overloaded with bells and whistles, but it covers the basics well: scheduling, no-go zones, and suction level settings. It’s easy for anyone to use without fuss.

Day-to-day, the N20 Pro handled pet hair, crumbs, and fine dust on a mix of surfaces with no trouble. One tester noted that it kept up with two shedding dogs and active kids, leaving floors noticeably cleaner every run.

Corners and edges often trip up budget robots, but the N20 Pro impressed by sweeping up along baseboards and into tight spots. Its edge cleaning is reliable enough for daily maintenance, offering peace of mind that messes aren’t left behind in the hardest-to-reach places.

There’s a key trade-off: you’ll need to empty the dustbin manually after every couple of cleanings. The N20 Pro doesn’t include an auto-empty dock, so maintenance is more hands-on than with pricier models. On the plus side though, this also means it takes up very little space, making it ideal for smaller homes or those who feel a robot vacuum would quickly become an eyesore.

You’ll also notice its suction is less powerful than the high-end competition. Compared to the Roborock Saros 20's 36,000 Pa, the N20 Pro's 8,000 Pa suction may sound a little feeble. That's not to say it won't get the job done, but don't expect deep cleaning. Likewise, its mopping feature is really just for light touch-ups, lacking the agitation you'll get with spinning pads, which can lift up dried-down stains.

We do our best to bring you a full set of controlled pickup results in our robot vacuum reviews, but at present, we don't have stats for the N20 Pro. However, reviewer Ashley has tested many robot vacuums in her home, and feels it's the best value option she's ever tested in both lab and real-world testing, which is why it's still featured in this guide.

Best robot vacuum for carpet

Affordable robot vacuum great for carpets

Specifications

Size : 17.7 x 17.7 x 17.7 inches
Power: 25,000 Pa
Mop type: Spinning pads
Dustbin capacity: 91 ounces
Dock dustbin: Self-emptying
Smart home compatibility: Alexa, Google Home, Matter

Reasons to buy

+
Excellent suction for deep carpet
+
Strong overall cleaning performance
+
Adaptive chassis handles thresholds
+
Hygienic hot water mop wash

Reasons to avoid

-
Mopping performance didn't wow us
-
Could be better at obstacle avoidance
Buy it if:

✅ You prioritize deep cleaning for carpets: The Qrevo Curv 2 Pro delivers 25,000Pa of suction and excels at deep-cleaning thick rugs, making it the obvious choice if carpet performance is your top need.
✅ You have many high floor thresholds: Its adaptive chassis design lets the Qrevo Curv 2 Pro cross thick rugs and room transitions without getting stuck, so homes with lots of carpet and thresholds will benefit.

Don't buy it if:

❌ You deal with heavy pet shedding: If pet hair is your main challenge, the Saros 20 outperforms the Qrevo Curv 2 Pro in that area — even though the Qrevo is better for deep carpet debris.
❌ Mopping is a top priority: While its carpet performance was hard to fault, we did have some complaints with the mop during testing.

The Roborock Qrevo Curv 2 Pro stands out as a strong option for deep carpet cleaning, whether you're dealing with thick rugs or wall-to-wall carpet. With 25,000Pa of suction power, it delivers robust overall cleaning performance that makes a noticeable difference.

In daily use, tester Matt found that it excels at pulling up embedded dust and debris from dense carpet fibers, while still providing solid performance on hard floors. Reviewers consistently praise how it tackles carpeted rooms, noting its effectiveness on a variety of fabric surfaces.

A key distinction is the adaptive chassis, which lets the Qrevo Curv 2 Pro confidently manage door thresholds and uneven carpet transitions. Matt found that it navigated thick rugs and furniture legs without getting stuck, making it well-suited for homes filled with plush carpet or mixed flooring.

Compared to our top pick, the Shark PowerDetect UV Reveal, the Qrevo Curv 2 Pro offers stronger suction, a clear advantage for deep carpet cleaning, even though its overall lab cleaning score is slightly lower when you factor in other floor types.

One limitation is the single brush arm. It occasionally leaves clumps at the edges, so if you’re picky about perfect side pick-up or often clean along baseboards, this trade-off is worth noting. This also impacted mopping performance. Reviewer Matt noted a range of "small but perceptible sticky smears from the spinning mops" after our ketchup tests, suggesting this is not the vacuum for tackling wet messes.

If deep carpet cleaning is your top concern, the Qrevo Curv 2 Pro offers strong performance compared to budget models for carpeted homes. But if you're dealing with mostly hard floors, you may prefer the Dyson Spot+Scrub.

Best robot vacuum and mop hybrid

A great robot vacuum and mop combo

Specifications

Size: 14.57 x 14.69 x 4.33 inches
Power: 18,000 Pa
Mop type: Rolling mop bar
Dustbin capacity: 100 ounces
Dock dustbin: Bagless self-emptying bin
Smart home compatibility: iOS and Android

Reasons to buy

+
Strong mopping and stain removal
+
High-temperature water for cleaning
+
Strong suction and vacuuming
+
Accurate mapping and navigation

Reasons to avoid

-
Large and bulky design with a divisive bagless bin
-
Not the cheapest hybrid option
Buy it if:

✅ You tackle sticky spills and dust simultaneously: The Dyson Spot+Scrub Ai handled dried-on food stains and sticky messes in our tests, delivering true dual-purpose cleaning that many hybrids miss.
✅ You find manual maintenance a chore: Its bagless, self-emptying dock means you don’t need to buy bags or empty a dustbin after every run, streamlining upkeep for busy households.
✅ Babysitting your robot frustrates you: Mapping was precise and setup a breeze, and once the Dyson was running, testers rarely needed to intervene—so targeted cleaning is easy and dependable.
✅ You want a simple, fuss-free interface: The Dyson’s simple controls and low-maintenance design mean it works quietly in the background without constant attention, making it ideal for hassle-free cleaning.

Don't buy it if:

❌ Your floor plan has tight spots: The Dyson is physically larger than most robot vacuums, so it’s less suited for homes with cramped layouts or low furniture.
❌ Finding a low-cost hybrid matters to you: This isn’t the cheapest hybrid robot out there, so shoppers on a tight budget may want to consider other options.

If you want a robot that truly vacuums and mops, the Dyson 360 Vis Nav Spot+Scrub Ai stands out for tackling dried-on messes, including stubborn kitchen stains, where many hybrids struggle. In our tests, it wiped away dried sauce and sticky spills with a single pass, giving it a clear edge in real-world mopping effectiveness.

What sets the Dyson apart is its mopping system. It uses high-temperature water, which helps break down grime and leaves floors feeling hygienic. And unlike any other vaccum featured in this guide, its rolling mop bar is constantly fed with a flow of clean water, meaning it's more likely to pick up dried-down messes, and less likely to spread dirt around your floors.

I tested this vacuum in my own home, and found that wherever the Dyson cleaned, it picked up dust and debris impressively well, handling everything from crumbs to long strands of hair without issue. Suction is only ok, though. With 18,000 Pa, it's not quite so powerful as the similarly-priced Roborock Qrevo Curv 2 Pro.

Navigation is another win. Mapping was accurate even in oddly shaped rooms, and setup was quick. I barely had to intervene after initial setup, a testament to how little hands-on maintenance is needed once it’s up and running, and in my continued daily use it very happily navigates around obstacles and changing floorplans with no drama.

For busy homes, the bagless, self-emptying dock is a genuine convenience. It automatically empties debris, reducing touch points, so you don’t have to worry about changing bags or frequent emptying. Still, there are trade-offs. The Dyson is larger than most robot vacuums, so it’s more noticeable in the room and may not fit under every piece of furniture. Its drying cycle after mopping can be noisy and takes longer than you might expect, which may bother those sensitive to sound or who need quick turnaround times between cleans.

The Spot+Scrub Ai is best for buyers who want strong, consistent hybrid cleaning and minimal daily fuss. If you don’t need every bell and whistle but value real mopping performance and low-maintenance vacuuming, this robot nails the hybrid brief.

Best value robot vacuum

The QV 35S gets the balance right between specs and price

Specifications

Size: 20.5 x 13.5 x 19 inches
Power: 10,000Pa
Mop type: Spinning pads
Dustbin capacity: 91 ounces
Dock dustbin: Self-emptying
Smart home compatibility: Amazon Alexa, Google Home, and Siri Shortcuts

Reasons to buy

+
Cleaned up most debris on hard floors
+
Simple and unobtrusive to use
+
Excellent obstacle avoidance
+
Long battery life
+
Strong suction for the price

Reasons to avoid

-
Struggles with high-pile carpet
-
Not as effective for heavy pet hair
-
Lacks advanced dock and mop features
Buy it if:

✅ You want a good value cleaner that really works: The QV 35S cleaned up most visible debris on hard floors in our tests, delivering reliable daily results at a reasonable price.
✅ Complex navigation and controls frustrate you: With reliable obstacle avoidance and easy app mapping, the QV 35S is simple to set up and use, even in cluttered or unmapped spaces.
✅ You're looking for low-maintenance cleaning: Setup takes minutes, and the self-emptying dock means you’ll rarely have to deal with daily dustbin dumps or complicated maintenance.

Don't buy it if:

❌ Deep cleaning and pet hair matter to you: The QV 35S isn’t as effective as pet-focused models on thick carpets or for picking up heavy pet hair, leaving behind more fuzz and debris.
❌ You expect advanced mopping or luxury features: While it has a self-emptying dock, the QV 35S lacks advanced mopping and premium dock features

While the Ecovacs Deebot is still our top pick for budget buyers, if you can afford to splash out on some key extras, you'll see the difference with the Roborock QV 35S. For one, it has a self-emptying dock, and its spinning mop pads are a big step up compared to the likes of the Deebot's basic pad.

When we tested the QV 35S on hardwood floors, its 10,000Pa suction was impressive, pulling up nearly all visible debris in a single pass. In home use, it rarely left behind dust bunnies or tracked-in grit, a level of performance that’s unusual for entry-level bots. You'll need stronger suction for deep-pile carpets, but it also fared well on shallow rugs, picking up an average 84% of debris across our three tests.

Navigation is another high point. The QV 35S proved adept at maneuvering around chairs in our testing area, rarely getting stuck or confused even when running with no pre-set map. While it has a bumper on the front, reviewer Ashley noted that she never saw the Roborock use it due to its excellent sensors.

Ashley also enjoyed using the Roborock app during testing. Its mapping process took under 15 minutes, and controls stayed intuitive throughout. Its 180 minutes of battery life is also impressive, and the QV 35S could comfortably cover large areas on a single charge.

The QV 35S includes a self-emptying dock and performs well on hardwood floors. You’ll give up advanced mopping and luxury extras, but for the money, this bot automates the basics better than most.

Also tested

We've tested many robot vacuums at Tom's Guide. While most perform great, they aren't as easy to recommend for everyone. That's due to a lack of features at higher prices or more niche use cases that aren't as versatile as the top models in our list. Still, the models below are worth checking out if money isn't an issue.

iRobot Roomba Plus 505 Combo
iRobot Roomba Plus 505 Combo: at Amazon

One of the newest Roombas of the range, the Plus 505 Combo is an impressive all-rounder. Not only does it excel in pet hair pick-up and grime, but its 70x-more, powered mop scrubs pet messes in no time. It also comes with AI-advanced features, a great app and can go up to 75 days of auto-emptying.

SwitchBot  K11 Robot Vacuum and Mop
SwitchBot K11 Robot Vacuum and Mop: at Amazon

Despite its small stature and budget price, this robot vacuum and mop hybrid did a great clean. This is thanks to its 6000 PA of suction power. In our tests, it impressed us with its pet hair suction, and managed to pick up every last bit of debris both on hardwood and carpet. Its only downfall was its mop cleaning and inconsistent mapping. However, its miniature size makes it perfect for smaller homes.

The all-in-one cleaning station can self-empty, self-clean, hot air dry, dispense detergent automatically, collect wastewater, and self-refill. Despite its decent performance and excellent mopping however, it fell short with picking up larger debris.

The SwitchBot K10+ Pro Combo robot vacuum scored top marks for innovative design. The robot vacuum and stick makes for an effective combo. In our tests, both were easy to use, had a great smart mapping system, and cleaned fairly well. However, it struggled picking up larger debris, such as cereal, and other heavy-duty messes. for money. Another caveat is the robot vacuum can't get into deep/sharp corners, or navigate around obstacles if the path isn't big enough.

Although the RS20 Pro did a decent job at maintenance cleaning, has plenty of settings, and a great app, it fell short on several other things. It couldn't cope well with heavy-duty messes, particularly when tested on cat litter. And considering there are cheaper models that perform better, this was a major downside. However, if you just need it for light cleaning, this is adequate, but you might want to consider other options.

How we test

Over the past 10 years, we've tested dozens of robot vacuums, both by performing objective tests as well as real-world setups.

Each model we review is first evaluated to see how well it can pick up three types of debris. We measure out 20 grams of Cheerios, 20 grams of kitty litter, and 20 grams of pet hair.

Next, we scatter each individually across a hardwood floor, and then weigh the contents of the robot vacuum's dustbin to see how much of each it picked up. We then repeat the same three tests on a low-pile carpet. Afterwards, the robot vacuum receives a cleaning performance score, which is the percentage of debris it was able to collect.

After we record each robot vacuum's scores, we let these machines loose in our tester’s home to see how each holds up in terms of navigation, obstacle avoidance, and coverage in real-world testing. Any special features such as app control, mopping functions, and self-emptying bases are factored in too. This all adds up to weeks of testing; it takes time, but helps ensure we're evaluating them all properly.

How to choose the best robot vacuum

Narwal Flow robot vacuum review

(Image credit: Future)

Before you start shopping for a new robot vacuum, you should consider what you need from it and how much you’re happy to spend. Here are some of the most common features you can find in robot vacuums.

Carpets or hardwood?

Most robot vacuum models can easily handle cleaning both carpets and hardwood, but some are better at cleaning one or the other. Higher-end robot vacuums can accommodate rapid surface changes by folding its mop pad atop itself and ramping up power whenever carpet is detected, and then throttling back down when it senses hardwood. Rugs should also factor into your buying decision. You might find that lower-end models will get caught up in tassels.

What features do I need to look for?

Features to look for include whether it has Wi-Fi compatibility. Most robot vacuums can connect to your smartphone via Wi-Fi, but some lower-end models don’t have this option. However, you can control and monitor your robot vacuum from your phones.

Additionally, battery life is important to consider and this will depend on your usage and settings. If you opt for a model which comes with a base, it can self-charge between runs. Plus, the dust canister needs to be a sufficient size. Look for a minimum of 400ml. The smaller the dustbin, the faster it will fill.

Another handy feature is a self-emptying base. Once the robot vacuum’s dustbin is full, it will return to its charging dock to ‘self-empty’. This is then stored in the dock until this larger bin is full and needs emptying, which you will need to do, usually once a month or less, depending on how often your robot vacuum cleans.

What is a "hybrid" robot vacuum?

Some robot vacuums also have a mopping function, so you can more effectively clean your hardwood floors and tiles without needing one of the best robot mops. More importantly, it will save you the back-breaking chore of using a traditional mop and bucket!

Mapping functions

Most smart robot vacuums can map-out your home using sensors, so they can remember any obstacles, such as the stairs, and let you identify specific rooms/multiple floors.

Some models allow you to set no-go zones if there’s certain areas you want to avoid, targeted rooms or particular areas.

Scheduling features

This is quite a common feature for robot vacuums. By connecting with your smartphone app, you can schedule when you want it to clean, be it daily, weekly or when you’re not at home.

Robot vacuum FAQs

Should you get a self-emptying base?

Premium robot vacuums often come with self-emptying charging bases. These start from about $500 and can go as high as $1,400 with the latest features. There are lots of benefits to getting a self-emptying base. First, your robot vacuum can literally self-empty, so if the onboard dustbin is filled mid-route, it can empty itself and then continue cleaning uninterrupted. A self-emptying base saves you from the chore of emptying the dustbin so often as well, with most bases able to hold a minimum of 45 days of dust.

If your robot vacuum has a mopping function, some bases come with water tanks and scrubbing abilities as well, so it can keep the mop cloth clean. However, there are some drawbacks to self-emptying bases. Besides the additional cost, these take up a lot more floor space.

Can a robot vacuum replace a normal vacuum?

Robot vacuums have improved tenfold since they were first introduced, both in terms of navigation and pickup. And while the gap between these devices and upright models is indeed closing, there is still admittedly a gap. Robot vacuums do not offer as strong a performance as upright vacuum cleaners, particularly corded ones. It’s for this reason that we don’t recommend throwing away the best vacuum cleaner even if you decide to invest in one of these strong contenders.

Robot vacuums are recommended more for light, everyday cleaning, rather than for handling really embedded debris. So, ideally you will still want to run your regular vacuum every so often, while the robot vacuum helps keep dust down in the interim. By keeping on top of the light debris, you won’t need to use your full-sized vacuum so often.

Where should I place my robot vacuum?

First and foremost, you should follow the directions in your instruction manual for where to place the robot vacuum. While most will offer similar guidance, the measurements required can vary, and some designs may prefer a greater clearance. Generally speaking though, your robot vacuum should be placed against a flat and straight wall on a level surface, with around 3 ft of clearance on each side, and at least 4 ft in front. This is so that it has adequate space to start cleaning and dock on re-entry, without any furniture getting in the way. Don’t forget that it needs access to a power socket as well.

If you’re using a standard charging base, you may have to fix it to the wall, so the robot vacuum won’t knock it out of place. Some bases come with stickers to help with this issue. If you’re lucky enough to own a robot vacuum with a self-emptying base, it should be heavy enough to hold itself in place. Although this does mean it will likely require more clearance space and will protrude further out from the wall as well. Make sure you have a space in mind for your robot vacuum’s dock before you make a purchase, otherwise you might have to move some furniture around.
