Quick verdict
A battery-powered vacuum lifter with a 20 litre per minute pump that seals onto rough, dusty and semi-porous surfaces that a hand suction cup cannot hold, with an automatic pump that keeps the vacuum up as air seeps in and a digital gauge that shows the hold, so riven sandstone, textured concrete pavers, wet slabs, plywood and drywall are lifted and placed by one person with a handle instead of fingers under the edge. It is the tool paving crews moved to for relaying patios, and the Pro adds the auto pump and gauge that make a long session safe.
Strengths
- Lifts rough and porous pavers that hand cups cannot grip
- Auto pump maintains vacuum as air seeps through the stone
- Digital gauge shows the seal strength before lifting
- One-person lifting and precise placement
- Also lifts plywood, drywall, glass, tile and metal
Weaknesses
- Costs many times a hand suction cup
- Battery and seal are consumables; keep spares
- Very rough or crumbly stone still seeps faster than it pumps

The Slab a Suction Cup Lets Go
A hand suction cup lifts a polished slab and slides off a riven one, because air seeps through the texture faster than the cup can hold. A powered lifter pumps the air out as fast as it comes in. The GRABO Pro is a battery vacuum lifter with a 20 litre per minute pump, an automatic mode that tops up the vacuum and a digital gauge, and it holds rough sandstone, textured concrete and wet slabs that nothing else will.
This review is based on the maker’s specifications and on how powered vacuum lifters are used in paving and construction generally. We have not used this lifter ourselves.
On a Patio
Brush grit off the slab. Set the foam pad flat on it and press the button; the pump draws down and the gauge climbs. When the reading is in the safe band, lift by the handle, carry the slab the few feet to its bed and lower it. Release and the slab is placed to the millimetre with no fingers under it. A sunken slab is lifted, re-bedded and replaced in minutes, and a whole relaid patio is a day instead of a back injury.
Auto Pump and Gauge
Porous stone leaks continuously. The Pro senses the drop and runs the pump to hold the vacuum, which is what makes a long carry safe. The digital gauge shows the seal before the lift, so a slab that is too crumbly to hold is known before it is off the ground.
Beyond Paving
Plywood and OSB sheets onto a roof, drywall into position, a glass panel, a stone countertop, a steel plate, a tile. Builders of every kind have adopted it for the same reason as pavers: one person, no edge to grip, no fingers in the gap.
Consumables
The foam seal wears on rough stone and tears on a sharp edge; it replaces in a minute and a spare lives in the case. The battery charges between jobs and a second one keeps a crew going.
Safety
Lift within the gauge band, keep the load low and never over a foot or a hand. A powered lifter is strong enough that a dropped slab is a serious injury; the gauge is the safeguard.
Who Should Buy It
- Anyone relaying a patio in riven or textured stone.
- Landscapers and small paving crews.
- Builders handling sheets, glass and stone alone.
Common Owner Complaints
Price and seal wear. It is a professional tool; keep a spare seal.
Alternatives to Consider
The GRABO Nemo for a lighter-duty version. A pump suction cup for smooth slabs only. A slab clamp for a cheap mechanical grip.
Verdict
For rough pavers and slabs, a powered vacuum lifter is the tool that finally works, and the Pro adds the auto pump and gauge that make it safe for a day of lifting. Brush the slab, watch the gauge, keep the load low.

GRABO Pro Electric Vacuum Suction Cup Lifter with Auto Pump and Digital Pressure Gauge FAQs
A hand cup holds only on smooth non-porous surfaces because it cannot replace the air that leaks in. The GRABO pumps continuously, so it holds on textured and porous stone where air is always seeping.
Brush the slab, set the pad flat, press the button; the pump draws the vacuum and the gauge rises. Lift by the handle, place the slab on the bedding and release. Relaying a sunken slab is a two-minute job.
The rating on a clean non-porous surface is well over 100 kg; on rough stone it is lower and the gauge says how much seal there is. Never lift above a foot or a hand.
The foam seal and the battery. Both replace, and a spare seal in the case means a torn one does not end the day.
