Bosch Unlimited 7 Aqua: two-minute review

The Bosch Unlimited 7 Aqua is marketed as a hybrid hero: part cordless vacuum, part mop, all in one sleek stick. It sits alongside the regular Unlimited 7, which is a standard cordless vacuum, but the Aqua version comes with two floorheads: a powered vacuum head, and a mopping head with suction. As such, it’s a direct rival to Dyson V15s Submarine, but with a lighter feel and a friendlier price. However, after using it for nearly three weeks, I found it wasn’t quite up there with the best wet and dry vacuums on the market.

On test, I found this vacuum light and nimble, with a properly practical design. There’s a long, flexible nozzle attachment for getting behind radiators, and the main vacuum wand can be released to bend forwards to 90 degrees too, enabling me to skim under sofas, kickboards and low tables without crouching or dragging furniture around.

However, it’s not well suited to strenuous cleaning. With the vacuum head attached, suction was strong enough for everyday crumbs, dog hair and dust bunnies, but not on a par with the best cordless vacuums on the wider market – it struggled to get fine dust out of carpet and wasn’t great on edges, either. The mop head did a decent job of freshening up hard floors, but tended to smear spillages around rather than mopping them up. Plus, the gap between the two rotating pads meant several passes were required for complete coverage. Both the dustbin and water reservoir are quite small, which means frequent emptying and refilling.

Still, if you live in a smaller home, perhaps with mostly hard floors, and are just looking for an all-in-one solution for everyday use, the Bosch Unlimited 7 Aqua is well worth a look. You’ll still need to dig out the mop for more thorough cleans, but this stick vacuum will help keep things fresh in the meantime. Read on for my full Bosch Unlimited 7 Aqua review.

Bosch Unlimited 7 Aqua review: price & availability

• List price: £499.99 / AU$699
• Launch date: January 2024 (AU), April 2024 (UK)
• Available: UK and Australia

In the UK, the Unlimited 7 Aqua officially launched in April 2024, and it’s already seen some decent discounts. The list price is £499.99, but at the time of writing I spotted it on offer for £379.99 with free delivery (which actually makes it cheaper than the base Unlimited 7). Considering the Aqua version comes with a handy mop head as well as the standard vacuum attachment, it feels like a no-brainer if you’ve got hard floors.

Over in Australia, the Unlimited 7 Aqua arrived in January 2024 with a price tag of $699. That puts it neatly in line with the rest of the Unlimited 7 range, which varies between AU$549 and AU$749 depending on which bundle you go for (extra batteries, pet brushes, that sort of thing).

I haven’t spotted any consistent discounts yet, so it’s probably safest to assume it’ll be sold close to full price for now. Sadly, Bosch doesn’t sell its vacuums in the US, so the Unlimited 7 Aqua won’t be making its way across the pond as far as we know.

As for where it sits in the market, the Aqua is at the lower end of the premium sector in both territories. But given the solid build quality, the option to mop and vacuum in one go, and Bosch’s reputation for durability, I’d say it’s pitched fairly.

Bosch Unlimited 7 Aqua review: design

• 2-in-1 vacuum and vac-mop, with separate heads for each
• Slim, lightweight, yet solid build
• Flexible wand and bendy hose get into hard-to-reach places

In the box, the Bosch Unlimited 7 Aqua comes with everything you’d expect, and more. You get two floorheads (a powered floorhead for vacuuming and the Aqua mop/vac head), a bendable hose, charging cable, battery pack, docking station, a 2-in-1 furniture brush, both short and long, bendy crevice nozzles, plus four textured pads for the mop.

It’s a generous bundle that meant I could get stuck in straight away without feeling short-changed on accessories. You can also store a couple of the nozzles on the wall-mounted docking holster once you’ve decided where it’s going to live.

The vacuum itself is slimline and lightweight and, crucially, it doesn’t feel top-heavy in the hand the way some stick vacs can. All the attachments click into place with satisfying smoothness, and the release buttons are ergonomically positioned, so swapping heads mid-clean never felt fiddly.

If I were to compare it to a car, the build quality was giving VW energy: solid, reliable, and clearly engineered to last, even if it doesn’t have the glossy, showy looks of a Merc or Beemer.

Controls are nice and simple. A single slider toggles between Eco, Turbo and Auto, and I mostly left it parked on Auto. Battery life is shown by three LEDs that switch off one by one as the charge drops. It’s functional, but a bit vague info-wise compared to a modern digital display.

The flexible hose was one of my favorite design touches. It bends like an elbow joint, letting me sweep under sofas and kickboards without crouching. I also made good use of the bendy crevice nozzle, which snaked neatly behind radiators and into tight spots.

The roller floorhead mixes stiff and soft brushes, though I couldn’t see an obvious way to pop the roller out for detangling hair without a screwdriver, which felt slightly old-school.

The mop head, on the other hand, is refreshingly straightforward: a lozenge shape with two spinning pads that attach via Velcro. Fill the small tank with water (and a splash of floor cleaner if you like), press a button to dampen the pads, click it back into place, and you’re ready to mop. All in all, the Unlimited 7 Aqua’s design is practical, flexible and reassuringly well built. It’s not especially flashy, but it’s smart where it counts.

Bosch Unlimited 7 Aqua review: performance

• Strong suction and flexible cleaning
• Mop tends to swish dirt around
• Small bin and tank need frequent stops

Since the Bosch Unlimited 7 Aqua is a game of two parts, I’ll start by covering the general stuff like ease of use, noisiness and maintenance, then focus on mop-ability.

Maneuvering the Bosch Unlimited 7 Aqua is effortless. Regardless of which floorhead is attached, it glides smoothly across every surface, getting tight to edges and right into the corners with ease, and barely needing any force, thanks to the powered floorhead.

On test, I especially loved the flexible main tube, which I could unlatch and bend to reach right under sofas and low furniture without having to twist my own body like a contortionist. It’s also very lightweight, even for a stick vacuum, so I could lift it up onto the sofas and upholstered ottoman, staircase runner etc.if I was feeling lazy, or switch to handheld vacuum mode if I wanted a bit more precision.

The array of nozzles make the fiddlier tasks easy, too. The crevice tool and furniture brush work exactly as expected, but my fave is the bendy long crevice nozzle, which managed to get into all the nooks and crannies of my fancy (but impossible to clean) radiators and also provided good reach for ceiling cobwebs and curtain rails.

This cordless is so light, I often didn’t bother switching to handheld (Image credit: Future)

While the mop head has a vacuum function, it’s really only designed to clear the way for mopping. For carpets and dirty hard flooring, you’ll need to employ the excellent motorized floorhead.

I loved that it has decent LEDs on the front to illuminate every crumb, and the anti-tangle roller had no truck with my daughters’ long tresses. In terms of noisiness, which I recorded using an app, in Eco mode it was fairly quiet at around 68 dB(A), so I could easily hold a conversation while cleaning. Turbo definitely ramped things up, hitting about 80 dB(A) and sounding punchier, but I used this mode sparingly to save juice so it was never really an issue.

The suction on this thing is way punchier than I expected. Even in Eco mode it guzzled up crumbs, pet hair and muddy paw/boot prints without breaking a sweat. Auto mode was the real star though – I could hear it cranking things up the second I hit a rug, then chilling out again on hard floors.

The vacuum dustbin was annoyingly small and needed emptying far more regularly than my cordless Miele – this wouldn’t be ideal if you have plenty of pets. On the plus side, it was very easy to empty, and the filter has an easy-clean function whereby you turn the red wheel in the top and the dust pours out. No washing filters under the tap and waiting for them to dry before you can vacuum again.

Mopping

To set the scene, my floors are mostly hard surfaces (engineered wood, porcelain, laminate) and they do not get an easy ride. With two kids, two dogs (including a mischievous puppy), an escapee budgie who thinks he rules the roost, and ponies that seem determined to send half the Devonshire countryside indoors on our boots and clothing, my mop and bucket get a lot of action throughout the week.

With that in mind, it’s fair to say the mop pads on the Bosch Unlimited 7 Aqua had their work cut out. They work by taking clean water from the reservoir to dampen the pads, then spinning fairly quickly as you push along, vacuuming at the same time. The mop head has a button you can press with your foot to charge the mop heads with water.

I found the mop pads spread the water and cleaning solution fairly evenly, except for the dry channel created by the gap between the two, which meant I did need to do multiple passes for full coverage. They definitely did some good, judging by the grubby pads afterwards – which were pretty grim, in a satisfying way.

If I’m honest, it often felt like the mops were pushing the dirt around rather than properly lifting it away. In short, when life got really filthy (pretty much every other day), I still needed to follow up with an old-fashioned mop to tackle the worst of it.

That’s the issue with this style of mop: although the pads are fed with clean water, the dirty stuff stays on them until the end of the cleaning session, when you can remove them and rinse them out or pop them into the washing machine.

In contrast, roller-based wet cleaners like the Dyson WashG1 have a scraper that siphons off dirty water as the mop pad rolls around. That kind of setup does require a separate dirty water tank, though.

That said, for everyday upkeep the Unlimited 7 Aqua was still a handy pal to have around. It gave our hard floors a nice little refresh, and I loved how quick and fuss-free it was compared with lugging out the mop and bucket.

For me, this is the machine to grab for a speedy once-over before guests arrive, i.e. when I want to pretend we don’t spend our days knee-deep in horse muck. But after a muddy hack through the fields or a puppy-induced disaster, the good old faithful mop was called back into action.

Cleaning tests

To really see what this machine was made of, I put the Bosch Unlimited 7 Aqua through a series of at-home tests that aim to replicate the kind of messes real families deal with daily. Here’s how it did.

Test 1: Fine dust
I started with a teabag’s worth of dry tea scattered on both hard floor and carpet. On hard floor, it was flawless – everything vanished in a single pass on Eco, without any effort. On carpet, though, it wasn’t quite as slick. Eco took several passes and still left bits behind until I cranked it up to Turbo, which eventually got the job done.

Test 2: Larger debris
Next up, 30g of oats scattered across the floor to mimic larger dirt particles. On hard floor it aced the challenge, sucking them up in one smooth pass without shoving them around like a mini snow plough. On carpet, they bounced about a bit at first, but a second pass on Eco cleared the lot.

Test 3: Edges
I lined oats along the skirting boards to see how close it could clean without swapping to a nozzle and was not terribly impressed. It needed multiple passes and still left a few stragglers that I had to tidy up with the crevice tool.

Test 4: Mop
This was the big one. I spilt milk on dark laminate and set the Aqua mop head to work. At first glance it looked promising… until I stopped and lifted it, at which point milk dribbled back out. Worse, when the floor dried, there was a faint white film where it hadn’t been properly cleaned.

A second test on my engineered timber floor seemed better at first, but a swipe with a wet wipe revealed plenty of dirt was still lingering. Safe to say, I won’t be relying on it for puppy accidents again anytime soon.

Overall, the tests showed that the Bosch Unlimited 7 Aqua is a strong performer on hard floors, handling both fine dust and larger debris with ease in Eco mode. Carpets were more of a challenge. It could cope, but often needed multiple passes or a boost to Turbo to get a thorough clean.

Edge cleaning wasn’t its strongest suit, and the mop function looked good at first glance but ultimately made me sad, leaving behind residue and proving unreliable for all but the quickest spruce-up.

• Performance score: 3 out of 5

Bosch Unlimited 7 Aqua review: battery

• Around 30 mins with the powered floorhead for vacuuming
• Mopping eats battery quicker, around 10–15 mins on Auto
• Turbo gobbles up the juice – about 9 mins max

Battery life on the Bosch Unlimited 7 Aqua isn’t mind-blowing, but it’s not a total washout either. In Eco mode, I squeezed out a respectable 41 minutes when using the smaller accessories, though the powered floorhead brought that down to about half an hour (28 minutes, if we’re being precise). Flick it into Turbo and the battery evaporates faster than my kids’ snacks after school – you’ll get around nine minutes before it keels over.

Mopping is another level of thirsty: with the Aqua head on Auto mode, I only managed 10–15 minutes before the lights started blinking. That said, I rarely needed Turbo when mopping, so it wasn’t a huge issue.

Charging is where Bosch redeems itself. Yes, it takes a yawnsome five hours if you plug it directly into the vacuum, but if you shell out for a fast charger base (not included as standard), that falls to just one hour, which feels far more realistic for a busy household. The battery is part of Bosch’s 18V Power For All Alliance, so I could technically pop it into a hedge trimmer or drill, which is pretty handy.

Overall, the runtime won’t blow you away, but I never ran out mid-clean in Auto mode. If you’ve got a bigger place or serious messes, a spare battery is your golden ticket.

Not dirt cheap, but you’re getting a vacuum and a mop in one, plus Bosch’s solid build. Deals make it even sweeter.

Design

Slim, light and packed with clever touches like the bendy wand. Feels sturdy and well thought-out, but not flashy.

4/5

Performance

Great suction on hard floors, less convincing on carpets and edges, and the mop turned out to be disappointing.

3/5

Battery

Enough juice for a decent clean, although Turbo and mop modes drain battery fast. Bosch’s fast charger (not included) is a lifesaver.

How I tested the Bosch Unlimited 7 Aqua

I spent nearly three weeks living with the Bosch Unlimited 7 Aqua, putting it through its paces in the chaos of my pet-filled four-bed family home in the country. To keep things fair, I ran TechRadar’s set tests, sprinkling fine tea leaves, scattering handfuls of oats, dragging it along skirting boards, and even pouring milk on my dark laminate to challenge the mop.

Day-to-day, I also used it for real-world chores: sucking up endless dog hair, chasing crumbs under the kitchen table, and tackling the fallout from pony gear being trailed through the hallway. The bendy wand and flexible crevice nozzle got a workout behind radiators and under sofas, while Auto mode proved handy for flitting between hard floors and rugs without me fiddling with settings.

I even gave the mop head a fair chance, though I quickly learned its limitations and gave up using it on Dotty the puppy’s many, many toilet-training fails. I generally found it quick, light and easy to use, even if it couldn’t quite conquer the messiest moments.
