Product Overview
The 4 inch Gekko Hand Tool is a handheld tool for cleaning grout lines in walls, countertops and other areas that a floor tool cannot reach. It is the handheld version of the 4 inch Gekko Head (AR51D).
Important — Hand Tool, Not a Wand Head
This is a complete handheld tool. It is not the 4 inch head that fits the Gekko wand — that is AR51D.
The two are easy to confuse because both are described as the Gekko 4 inch. Check which you need before ordering: if you are buying something to fit a Gekko wand you already own, you want the AR51D.
Where It Is Used
- Wall tile and grout, including showers
- Countertops and splashbacks
- Stair risers, ledges and toe kicks
- Any tight space too small for a floor tool

Hydro-Force does not publish a weight or hose connection size for this tool, and there is no spec sheet or parts breakdown in the manufacturer's document libraries. Rather than estimate figures, we have left them out — ask us and we will confirm the connection before you order.
What It Runs On
Any truckmount or high-pressure portable extractor. Around 1,000 psi is sufficient for tile and grout work; the 2,000 psi rating is headroom rather than a target.
Operating Advice
- Control the water on vertical surfaces. Wall and shower work throws more than floor work, and a shower recess concentrates it.
- Work along the grout line rather than across the tile face.
- Do the vertical surfaces before the floor, so anything that runs down is picked up by the floor pass.
Frequently Asked Questions
Does it fit the Gekko wand?
No. It is a complete handheld tool. The wand head is AR51D.
What is the difference between this and the AR51D?
The same 4 inch cleaning width. This one is handheld; the AR51D fits the Gekko wand for floor work.
Can I use it on shower walls?
Yes, and that is one of the jobs it exists for. Watch the water in an enclosed recess.
Do I need it if I have the SX-7?
The SX-7 (AR51G) covers handheld and upright work on the Gekko wand. If you already run it, this is a duplicate for most operators.
What We See in the Field
The Gekko range gets bought head by head over time, and the generation question is what catches people out — an old wand with a new head, or the reverse, bought months apart from different places. Check the generation before ordering rather than after.
The other pattern is pressure. Operators who are disappointed with a hard surface result are usually short on dwell time or running the wrong chemistry, and no amount of extra pressure at the tool makes up for either.
