@slmkhoo Hope it works for you! Not sure if the vibration can reduce strain on your arms… it is quite strong. I used it to scrub the tiles in my bathroom, and it is back breaking work just squatting down. But it does the job (or rather I did the job). Probably do it only every quarter.

I just bought one, and used it once so far. It does save some strain on my arms though not totally. Did a fair job of scrubbing the tiles and grouting. Have you tried using the extendable pole so you don’t need to squat? I haven’t tried that.

@slmkhoo I bought a scrubber from Shopee. Here’s the link:

It’s USB chargeable. I liked it. The charge last quite a while and the motion is pretty strong. I had to hold on to it tightly to stop it (or me) from flying off. It might be what you are looking for.

I’ve just ordered one. Hope it works for me! My elbows and wrists are OK at the moment (after a week’s holiday without cooking or housework!), but I know that they will be overtaxed easily as they are now inherently weak.

Not very sure it’s available there but you can checkout handy shop, like Self Fix.
