Quick verdict
A 40V brushless cordless 3-in-1 that blows, vacuums and mulches, rated by MZK at up to 700 CFM and 180 MPH, with four speeds, a 10 second turbo, a 40 liter bag, wheels and two 4.0 Ah batteries in the box for up to 30 minutes of runtime. It suits a homeowner who wants no cord and no gas for a modest lot. The caveat is that MZK is a lesser-known brand with limited track record, and the 700 CFM figure is the maker's own.

Who this blower-vac is for
A cordless 3-in-1 is the leaf tool for a yard without a convenient outlet and an owner who does not want to keep gas around. The MZK 40V puts a brushless motor, a 40 liter bag and two 4.0 Ah batteries in one box, with wheels under the intake so the weight of a filling bag rolls instead of hangs. It is pitched at lawns and driveways on a modest lot where the leaf drop is real but not forest-scale.
This review is based on the maker’s published specifications and on recurring owner feedback. We have not run this product ourselves.
What you get
MZK lists a brushless 40V motor rated at up to 700 CFM and 180 MPH, four speed settings and a 10 second turbo burst, tool-free switching between blow, vacuum and mulch, a 15:1 mulch ratio, a 40 liter bag with a square connector and snap buckle, an internal suction tube described as anti-jam, a quick-access cleaning gate, an anti-static grip, and wheels with adjustable height. Two 4.0 Ah batteries are included and rated together for up to 30 minutes of continuous runtime. The listing does not state the unit weight, and it does not spell out the charger, so confirm what is in the box before ordering.
Blowing power
A stated 700 CFM is a big number for a handheld, and 180 MPH is a moderate one; together they describe a tool tuned to move volume rather than to blast wet leaves off concrete. Makers across this category quote peak CFM at the housing rather than the nozzle, so treat the figure as a ceiling. The four speeds let you sweep a bed edge gently and open up on the lawn, and the turbo burst is a sensible way to handle a stuck patch without running the battery flat on the top setting. Owners of 40V brushless blowers in this bracket generally find them strong enough for dry leaves and light wet work on a suburban lot, and short of a gas backpack for acreage.
Vacuum and mulch
The 15:1 ratio is above the class norm of around ten to one, which in practice means the 40 liter bag swallows a lot of leaves before it needs emptying. The anti-jam routing matters more than it sounds, since the usual blower-vac failure is a wad of damp leaves stuck at the tube joint; the cleaning gate gives a way in without dismantling the tool. The snap-buckle bag mount is a step up from the drawstring collars on some rivals. As with every machine in the class, dry leaves only, feed steadily, and keep acorns, twigs and gravel away from the impeller.
Runtime and batteries
Up to 30 minutes from two 4.0 Ah packs is the honest limit of this tool. A 40V brushless vacuum under load draws hard, and turbo draws harder, so a heavy fall drop on a quarter-acre is a two-session job or a wait on the charger. Having two packs helps if the charger can refill one while the other runs. The batteries are MZK’s own 40V platform and will not fit other brands’ tools, so the value case rests on this unit alone rather than a shared battery system.
Build, handling and ergonomics
Wheels with adjustable height and an anti-static grip are the comfort features, and they address the right complaints: a bag that drags the arm down and a dusty handle that tingles. The build is plastic in the normal way and the brand is a lesser-known name on Amazon, which shows in a thin record of long-term feedback and uncertain spare-parts support. A recurring theme with newer-brand cordless yard tools is that the tool itself is fine and the battery or charger is the weak point, so register the warranty on day one.
Living with it
Store the packs indoors at partial charge over winter, dry the bag after each use, and open the cleaning gate to clear the impeller after wet jobs. Warranty terms are on the product page and should be read closely for battery coverage. Keep the receipt; smaller brands handle claims through the seller more often than through a service network.
Alternatives to Consider
The Greenworks 40V blower-vac is the established cordless pick with a wide battery ecosystem behind it. The Worx 40V Trivac covers the same jobs with a better-known service path. If an outlet is within reach, the corded Craftsman CMEBL7000 removes runtime from the equation altogether and costs less to own.
Verdict
Buy the MZK 40V 3-in-1 if you want a cordless blower-vac with two packs, wheels and a big bag in one purchase for a modest lot, and you are comfortable with a lesser-known brand. Skip it if the leaf drop is heavy enough that 30 minutes will not cover it, or if you already own batteries from Greenworks, Ryobi or EGO and would rather stay on that platform.

MZK 40V Brushless 3-in-1 Cordless Leaf Blower, Vacuum and Mulcher with Two 4.0 Ah Batteries and 40L Bag FAQs
MZK rates the pair for up to 30 minutes of continuous runtime. That is at a moderate speed; turbo and the top setting pull it down. For a quarter-acre with heavy trees plan on recharging mid-job.
It gives a 10 second burst at full output to lift wet or stuck debris. It is a timed burst rather than a sustained mode, which protects the battery and motor from running flat out.
That is the maker's figure and there is no independent number in the listing. Treat it as a peak claim measured at the housing rather than a working figure at the nozzle, which is normal practice across the category.
MZK routes the suction through an internal tube so leaves do not catch at the joints between sections, and a square connector with a snap buckle holds the bag so it cannot twist loose. A cleaning gate gives access if something does lodge.
