Have we ever wished mowing our small, uneven lawn felt less like a chore and more like a quick, simple task we could actually finish without wrestling with a heavy machine?
What Is the BLACK+DECKER BEMWH551-QS Electric Hover Mower?
This BLACK+DECKER BEMWH551-QS is a compact, corded 1200W electric hover mower with a 30 cm (12″) cutting width, designed especially for small gardens up to 250 m². Instead of running on wheels, it floats on a cushion of air, which lets us move it easily in multiple directions, including on slopes and bumpy patches.
We get a lightweight mower that is made for quick, straightforward lawn care rather than heavy-duty landscaping. It promises easy maneuverability, simple storage, and lawn-friendly features that should suit small urban and suburban lawns.
Key Specifications at a Glance
When we are short on time, it helps to see the key numbers laid out clearly. This hover mower is built around simplicity, but the details still matter if we want to be sure it truly fits our lawn.

Design and Build Quality
The overall design of the BLACK+DECKER BEMWH551-QS is centered around its hover functionality and compact footprint. Instead of a large metal chassis on wheels, we get a streamlined, plastic deck that rides on a cushion of air when the motor is running.
We should not expect premium metal finishes here; this is very much a practical, plastic-bodied mower, but that also keeps the weight down. At 6.93 kg, it is reasonably light for an electric mower, which makes it easier for us to carry, lift, and store between uses.
Compact Size for Small Gardens
The 30 cm cutting width makes this mower compact enough for tight corners and narrow paths where a bulky wheeled mower might be awkward. It is clearly targeted at lawns up to 250 m², which covers most small gardens, courtyards, and modest front lawns.
In daily use, this compact size means we can work around flower beds, under low shrubs, or near fences without constantly bumping into things. It is a sensible size if our main concern is a neat lawn rather than fast cutting over big spaces.
Hover Technology and Multi-Directional Movement
One of the standout aspects of this mower is its hover system. Instead of rolling on wheels, the mower lifts slightly off the ground on a cushion of air created by the motor and blade rotation. That effect is what makes it “hover.”
For us, this translates into very easy movement. We can push it forward, pull it back, and even move it sideways or at angles with less resistance than a classic wheeled mower. The multi-directional cutting capability is especially noticeable when we are trimming around awkward shapes and tight spots.
Why Hover Mowers Work Well on Slopes
Hover mowers like the BEMWH551-QS tend to handle sloped or uneven lawns better than traditional wheeled mowers. Because the mower is not relying on wheels to keep a fixed height off the ground, it can float over small bumps and dips.
This means we are less likely to scalp the high spots or miss grass in low patches. The deck maintains a more consistent distance from the grass, which helps avoid the “patchy” look we sometimes get when we use rigid, wheeled machines on lumpy lawns.
Power and Performance (1200W Motor)
The BLACK+DECKER BEMWH551-QS is armed with a 1200W electric motor, which is quite adequate for small lawns and typical domestic grass types. It is not meant to tackle overgrown fields, but for regular maintenance, the power output is well judged.
With 1200W, we get enough strength to keep the blade spinning briskly and maintain the hover effect, even when we encounter slightly thicker patches of grass. We might notice a bit of strain if we let the lawn grow very long between cuts, but for weekly or fortnightly mowing, the motor power should feel sufficient.
Quiet Operation vs. Petrol Mowers
While no mower is ever silent, this corded electric model is described as quiet relative to petrol alternatives. There is still a clear hum and airflow noise, but the absence of engine rumble and exhaust makes mowing more comfortable for us and less intrusive for neighbours.
We might still want ear protection if we are sensitive to noise, but overall, it is far less aggressive on the ears than a conventional petrol machine.
Cutting Width and Height Adjustments
The 30 cm cutting width is modest, but that is by design. For lawns around 100–250 m², it finds a balance between maneuverability and efficiency. We can cover small lawns in a reasonable time without struggling to navigate obstacles.
Cutting Heights: 20, 30, and 40 mm
The mower offers three adjustable cutting heights: 20 mm, 30 mm, and 40 mm. This gives us a basic but useful range:
- 20 mm: A short, close trim for formal-looking lawns.
- 30 mm: A balanced, everyday length for most conditions.
- 40 mm: A slightly longer cut, helpful in hotter conditions or when the grass is a bit stressed.
We should not expect a large number of micro-adjustments like on premium cylinder mowers, but these three height settings cover what most small-lawn owners actually use. It is a practical set of options, and the 20–40 mm range ensures a neat, tidy finish rather than an over-long, shaggy cut.
Winged Blade for Better Cutting and Collection
The mower uses a winged blade, which is designed to both cut and create airflow to help lift and disperse the grass. While this product is more about simple cutting than bagging and collection, that blade design still improves efficiency and cutting consistency on uneven ground.
We will likely notice that even slightly damp or thicker grass gets sliced more evenly because the wings generate enough airflow to stand the grass up just before the blade cuts.
Corded Power: Pros and Cons
This is a corded electric mower, powered via the mains. That brings a few very clear advantages and some compromises we should consider before buying.
Benefits of a Corded Hover Mower
- Unlimited runtime: As long as we are plugged in, we can mow; there is no battery to recharge or petrol to refill.
- Consistent power: The motor runs at a steady output, which means no performance drop as we go.
- Lower running costs: Mains electricity is generally cheaper and cleaner than petrol, and we do not have to buy oil or maintain fuel systems.
- Lighter than many battery mowers: Because there is no heavy battery pack, the unit stays relatively light and easy to handle.
Limitations of the Power Cable
The listed cable length is about 46 cm, which effectively means we must use our own extension lead for real-world mowing. That is an important point: this mower assumes we already have (or are happy to buy) a suitable outdoor-rated extension cord.
We will need to:
- Plan our mowing route to avoid running over the cable.
- Keep the cable positioned behind us or to the side.
- Use a good quality extension lead with the correct rating for outdoor use.
If we are comfortable with that, the corded design is a non-issue. If we dislike managing cables, a battery mower might be more appealing, but we would likely sacrifice some lightness and pay more.
Handling, Maneuverability, and User Comfort
Maneuverability is the core of what sets this hover mower apart from many budget options. Because it floats on a cushion of air, we can easily push it, pull it, and sweep it side to side without fighting the usual friction of wheels on grass.
Multi-Directional Cutting in Practice
In real use, the multi-directional motion helps us:
- Work around trees, planters, and garden structures.
- Tidy tricky corners of the lawn without awkward three-point turns.
- Maintain sloped areas with less effort, as we are not pushing against gravity as strongly.
We may find ourselves using more of a sweeping, gliding motion rather than rigid forward-and-back stripes. For small lawns that do not require perfectly striped patterns, this style of mowing is quick and convenient.
Weight and Grip
At 6.93 kg, the mower strikes a reasonable balance between feeling substantial and not being a burden to carry. We can pick it up with one hand on the handle and another under the deck if we need to move it between the front and back garden.
The product information notes that there is no soft grip, so the handle is standard plastic or metal without an extra padded covering. For short mowing sessions typical of small lawns, this is rarely an issue, but if we have sensitive hands or like extra comfort, we may notice the basic grip.
Performance on Different Lawn Types
Not all small lawns are equal. Some are flat like a bowling green, while others are patchy, sloped, or riddled with bumps and roots. The BEMWH551-QS is specifically pitched as being well-suited to sloped and uneven lawns, and that is where it can really shine.
On Flat, Small Lawns
On a simple, flat, small lawn, this mower performs very predictably. The hover action feels smooth, and we can cover the whole area quickly with overlapping passes. We may find ourselves finishing in less time than with a heavier, wheeled model.
The 30 cm width is ideal for modest lawns, so if our grass area is similar to a small back garden or front patch, we will appreciate how quick and easy it is to guide around.
On Sloped or Uneven Ground
Uneven ground is where hover mowers demonstrate their advantage. Instead of wheels dropping into dips or catching on bumps, the mower floats over the surface, keeping the blade closer to a consistent cutting height.
For us, this means:
- Fewer scalped patches on high spots.
- Better coverage of low spots that wheels might skim over.
- Less physical effort when mowing on a slope because we are not pushing heavy wheels uphill as strongly.
If our lawn is particularly rough, full of small humps or slopes that frustrate traditional mowers, the BEMWH551-QS can feel like a relief.
Suitability for Lawns up to 250 m²
BLACK+DECKER recommends this mower for gardens up to 250 square metres, which is roughly 1.2 tennis courts. That gives us a clear upper limit: it is not built for very large properties.
For lawns within this size range, we can expect:
- Manageable mowing times, usually under 30–40 minutes depending on how thorough we are.
- Little fatigue because the mower is light and glides easily.
- Minimal stress on the motor, assuming we cut regularly.
If our lawn is significantly larger than 250 m², we may find the 30 cm cutting width too narrow, and mowing sessions may become longer than we would like. In that case, a wider mower would be more efficient.
Storage and Portability
Storage can be as important as performance when we live in smaller homes or have limited shed or garage space. The BEMWH551-QS is clearly designed with compact storage in mind.
Folding Handle for a Smaller Footprint
The folding handle allows the mower to occupy much less space when not in use. We can fold it down and stand the deck against a wall or tuck it under shelving.
For us, that means:
- Easier storage in small sheds, balconies, or utility rooms.
- Less clutter when we already have other garden tools to store.
- Simpler transport in a car boot if we need to take it to another property.
Because the hover design eliminates big wheel assemblies, the overall shape is flatter than many standard lawn mowers.
Light Enough to Carry
At under 7 kg, we can carry this mower with modest effort. That helps when we have steps to navigate, different garden levels, or a long walk from our storage space to the lawn area.
If we have limited upper body strength, we may still feel the weight, but compared with many heavier mowers, this is on the more manageable side.
Ease of Use and Setup
One of the core strengths of a straightforward hover mower like this one is how little setup and maintenance it requires.
Getting Started
Typical first-use steps will be along these lines:
- Unfold and secure the handle according to the instructions.
- Check that the blade is properly fitted and tightened.
- Plug the mower into a suitable outdoor extension lead.
- Set the cutting height (20, 30, or 40 mm) as desired.
- Switch on and begin mowing, keeping the cable behind us.
We do not need to worry about fuel mixing, oil changes, battery charging schedules, or pull-start mechanisms. Once assembled the first time, future mowing is mostly a matter of plugging in and going.
Simple, Straightforward Controls
We should expect basic on/off controls rather than a panel full of complex settings. This suits the design philosophy of the product: a quick, compact mower for small lawns without unnecessary complexity.
For those of us who prefer a “plug and mow” experience, this simplicity is ideal.
Maintenance and Blade Care
Although maintenance on an electric hover mower is minimal compared with petrol machines, we still need to give it some basic attention to keep it working well and cutting cleanly.
Cleaning After Use
After each mowing session, it helps if we:
- Unplug the mower completely.
- Turn it over carefully.
- Brush or wipe away the grass clippings from under the deck and around the blade.
- Check for any stuck debris or stones.
Keeping the underside clean helps the hover effect work properly and avoids built-up grass affecting the airflow. It also prevents lingering moisture from creating unpleasant odours or accelerating corrosion on metal parts.
Blade Sharpening and Replacement
The winged blade will dull over time, especially if we occasionally hit small stones or hidden debris. A dull blade tears grass rather than slicing it, which can make the lawn look ragged and can stress the grass.
We should:
- Inspect the blade periodically.
- Sharpen or replace it when we start noticing uneven cuts or frayed grass tips.
- Always follow safety instructions when handling or replacing the blade.
BLACK+DECKER blades are generally easy to source, so replacement should be straightforward when needed.
Safety Considerations
Even a small, quiet electric mower needs to be used with care. The BEMWH551-QS is safer than petrol options in some respects, but it still has a fast-spinning blade and high-speed airflow.
Cable Safety
Because this is a corded mower, cable safety is critical. We should always:
- Keep the cable behind us, never in front of the cutting path.
- Use a brightly coloured extension cord rated for outdoor use.
- Regularly check the cord and plug for damage and never use if they are compromised.
Some of us like to start mowing close to the power source and work away from it, always keeping the cable trailing behind rather than crossing in front of us.
General Safe Use
We also want to:
- Only mow when the grass is reasonably dry to avoid slipping and overloading the motor.
- Clear the lawn of stones, branches, and toys before starting.
- Wear closed shoes and, if desired, eye protection against debris.
- Keep children and pets away while we mow.
These habits help keep mowing safe and trouble-free.
One-Year Manufacturer Warranty
The mower includes a 1-year manufacturer warranty, which gives us basic protection against defects in materials or workmanship. We should always check the specific warranty terms in our region and make sure we keep proof of purchase.
While a year is standard at this price level, it also reflects that this is a consumer-grade, not professional, tool. It is built to be reliable for its intended use—small, domestic lawns—rather than for continuous, heavy commercial use.
If we appreciate extra peace of mind, we may wish to register the product with BLACK+DECKER (where applicable) and follow any recommended usage guidelines.
Strengths of the BLACK+DECKER BEMWH551-QS
To help us decide if this mower fits our needs, it helps to summarise its main strengths. These are the aspects where it stands out versus many low-cost alternatives in the same class.
Excellent Maneuverability for Small, Tricky Lawns
The hover design and lightweight body make it very easy to move around. If our garden has curves, corners, and irregular shapes, this mower lets us work more freely than a heavier wheeled model.
We can move in different directions without much resistance, which is especially nice around patios, raised beds, or other landscaping features.
Designed for Slopes and Uneven Ground
The mower is particularly well-suited to sloped or bumpy lawns. We do not have to constantly adjust for wheels tipping into hollows. The hover effect keeps the cutting deck gliding smoothly, which results in a more uniform finish.
For many of us with older or irregular gardens, this feature alone makes a strong case for choosing a hover mower.
Compact, Easy to Store, and Light to Carry
If we have limited storage space or need to carry the mower up and down steps, the folding handle and sub-7 kg weight are real advantages. We can often tuck it away in spaces where a large, wheeled mower simply would not fit.
This also makes it a good option for shared homes, small apartments with lawns, or secondary mowers at holiday properties.
Limitations and Things to Keep in Mind
No mower is perfect for everyone, and this model has a few limitations we should consider before buying.
Not Ideal for Large Lawns
With a 30 cm cutting width and a recommended garden size of up to 250 m², this mower is intentionally focused on smaller spaces. If we have a large lawn, we will likely find mowing with such a narrow deck time-consuming.
In that case, we may want to look at wider hover mowers or standard wheeled mowers with broader cutting paths to reduce our mowing time.
Cable Management Required
Because the cable is short (around 46 cm) and the mower is corded, we must be comfortable managing an extension lead during use. If we hate dealing with cables, this will feel like a compromise.
We should factor in the cost of a good-quality outdoor extension if we do not already own one.
Basic Comfort Features
The lack of a soft grip and advanced controls underlines that this is a simple, budget-friendly tool. Functionally it works well, but if we are looking for premium comfort features, adjustable ergonomic handles, or advanced grass collection systems, we will not find them here.
For short mowing sessions typical of its intended lawn size, most of us will find this acceptable, but it is worth noting.
Who Is This Mower Best For?
Putting all the strengths and limitations together, we can identify who is most likely to benefit from the BLACK+DECKER BEMWH551-QS.
This hover mower is a strong fit for us if:
- Our lawn is small to modest in size, up to about 250 m².
- We have slopes, bumps, or uneven patches that frustrate wheeled mowers.
- We prefer a lightweight, easy-to-store mower rather than a bulky machine.
- We are comfortable using a corded mower with an extension lead.
- We want simple, no-fuss mowing with straightforward controls and minimal maintenance.
On the other hand, it may not be ideal if:
- Our lawn is very large or we want to mow large open areas quickly.
- We strongly prefer cordless operation and do not want to manage power cables.
- We require a mower with advanced collection, striping, or comfort features for extensive use.
Everyday Experience: What Using It Feels Like
Beyond the specifications and technical details, what counts is how it feels when we take it out on a regular Saturday to tidy the lawn.
We plug in our extension lead, set the height, and start the motor. As the hover effect kicks in, the mower feels noticeably lighter, and we guide it with a fairly gentle push. We work across the lawn, gliding in short sweeps, adjusting direction easily around shrubs and borders.
The noise is there but not overwhelming, and we do not have to shout over a petrol engine. After a short session, the grass looks visibly tidier and more even, especially across small uneven spots that might have tripped up a rigid-wheeled machine.
When we are done, we unplug the mower, flip it over carefully, brush away clippings under the deck, fold the handle, and tuck it back into a corner without wrestling for storage space.
That is the kind of straightforward, low-stress routine this mower is designed to offer.
Final Thoughts: Is the BLACK+DECKER BEMWH551-QS Worth It?
If we are looking for an uncomplicated, compact mower for a small garden—especially one with slopes or uneven ground—the BLACK+DECKER BEMWH551-QS Electric Hover Mower makes a very compelling case.
We get:
- A 1200W motor with enough power for regular small-lawn maintenance.
- A 30 cm cutting width that suits compact spaces.
- Hover technology for easy, multi-directional movement.
- Simple height adjustments between 20, 30, and 40 mm.
- A folding handle and lightweight build for easy storage and carrying.
- A straightforward 1-year warranty for basic peace of mind.
We trade off cable management, a lack of premium comfort features, and a relatively modest cutting width, but for its intended role—quick, efficient mowing of smaller lawns—it delivers what it promises.
If our garden matches that profile and we value easy handling on slopes or uneven turf, this BLACK+DECKER hover mower is a practical, friendly, and user-focused option that can make regular lawn care feel far less of a burden and more like a simple, manageable task we can finish without fuss.
