TBH your expectations and requirements are too high and varied to be fulfilled by a single device. While a vacuum cleaner is a quintessential device for us City dwellers. Due to engineering limitations, all your expectations can't be done through a single device. Handhelds can't handle wet loads. Wet mopping is done well with robot cleaners., they too have lot of limitations. What will work quite well is a bagless wet and dry vaccum, like so. https://shopkarcherindia.com/wet-and-dry-vacuum-cleaner-wd-3-v-15-4-20.html This is quite bulky, you need storage, noisy and also consumes some power, but makes you smile everytime you use it cause the suction is quite insane. We use an older model of this at home and is running quite well for 10th year. Can clean anything and everything imaginable with this. Now there are a lot of brands in the space and with quite varied warranties, just research around the brands.
Second this WD3 model as I own one. It's ugly but it's cheap, reliable and does its job.
100% this - I have had the same Karcher for 10 years now and it works as well as it did on the day I bought it. They are practically indestructible, can handle long continuous use time and I literally have used mine to vacuum stones, sand, leaves, metal filings and everything in-between. I recommend them to everyone. My entire family and previous boss has them too😅😂 EDIT: I have a WD3, which is a smaller vacuum in the range and it’s a beast regardless😎
>So I needed a really strong vacuum to suck over a long distance. There are a lot of wet and dry vacuums with a ridiculous amount of air watts for much cheaper. (Edit: like this for example https://www.hardwarespecialist.com.sg/wet-dry-vacuums/3883-karcher-wd-3-wet-and-dry-vacuum-cleaner.html)
Karcher WD3, wij hebben 2 konijnen die permanent in de rui zijn en hun hooi overal verspreiden. Dit monster werkt echt kei goed hiertegen. Voordeel is dat je 'm ook voor natte dingen kan gebruiken en dat 'ie tegen een stootje kan.
Karcher WD3, Wet & Dry. Best one that's served me well for long. Had a Eureka Forbes one previously which went dead in under a year.
They've service centers all around Kerala. I've never had any problems with all these years of using my Karcher products, got a pressure washer and that vacuum. Just Google them and you can get their addresses. For longevity and product quality I'd recommend them. They're in an affordable range, check them out and see if it suits for your use.
