DEWINNER2 pcs 8'' Vacuum Suction Cup with Pressure Gauge, Heavy Duty Vacuum Suction Cup with Handle Lifter, Glass Suction Lifter for Granite, Tile, Glass Lifting, Black

Really good suckers. I've been using them to lay 1200x600 ceramic tiles (18kg each). They grip to the slightly rough surface of the tile really well. I'm able to lower the tiles into place and, impressively, lift then again even when partially stuck to the tile adhesive. The pressure guage is essential as it gives you warning when the suction is starting to reduce (they don't hold forever) so no risk of it giving it without warning.

Pleasantly surprised. Picks up 900 x 600 x 20mm porcelain tiles/slabs no problem. 14 laid so far. Lets see if it holds out for the other 74.

Fantastic, using them on slightly textured porcelain outdoor floor tiles, and they really grip, I didn’t think they would, these tiles are 600x900x19 so no lightweight.Also used them to pull an integrated washing machine out of its hole.These are quality, strong, well made, and grip like hell you physically cannot pull them off once you have got the pressure up into the green.

Very good product!! Using 50 times except maybe 5 or 6 slips where the suction loses grip but over all very good.

Excellent choice. Holds double glazed inserts perfectly. Make sure you set the vacuum

I purchased the DEWINNER 2-pack 8" glass vacuum suction cups to help with lifting large glass panels and tiles during a home renovation project. Despite the impressive claim of a 200kg load capacity, the actual performance was far from reliable.From the first use, I noticed the suction was inconsistent. One of the cups lost grip midway through lifting a standard glass shower panel — thankfully no damage was done, but it was a close call. I followed all instructions carefully, ensured the surfaces were clean and smooth, but the vacuum seal just didn’t hold properly over time.The pump feels flimsy and requires a lot of effort to build suction, yet it deflates quickly and without warning. There’s a red line indicator to show suction loss, but it appears almost immediately, even when not under full load. This completely undermines any confidence in its “heavy-duty” label.The carry case is a nice touch, but what’s the point if the tool inside isn’t up to the job? These might work for very light-duty tasks, but I wouldn’t trust them for anything over 20–30kg, let alone 200kg.Overall, this product is misleading and not suitable for proper industrial or even serious DIY use. I wouldn’t recommend them if you value safety and reliability.

I have just used these suction cups to lift 80 large format (900x600) 20mm porcelain slabs in place on a new patio on my own. The slabs have a R11 slip-resistant surface and so I was sceptical about their ability to lift them safely. However, the suction cups worked perfectly with no issues at all. Just keep an eye on the pressure gauges and make sure they are in the green segment before lifting. Also keep all contact surfaces clean. My initial reason for buying these was to make it easier for my back when lifting but the bonuses are you can position the slabs without trapping your fingers when laying and place the slabs exactly where you want them before tapping them down plus use them for fine adjustments. If you decide a slab hasn’t gone down correctly you can also just pump the suction cups up again and lift the slab up; this takes considerable force but they hold! You do need to keep an eye on the gauges at all times as given the R11 surface the pressure does drop. I would say approx 2 minutes until they go into the red section, but that’s plenty of time to lift, place in position, tap down and final positioning. These suction cups are fantastic and I thoroughly recommend them.

Best purchase - lifts large 60X90 porcelain tiles comfortably!
