I deliberately didn’t take the battery version but the corded version. It's a "VAX SpotWash Max Duo Carpet Cleaner - White & Tiger Blue". So mine is without the spin wash (not the pet version), but is the larger capacity tanks (really you need this), and the large 500W motor (you want this), you get three heads including the thin crevice head which is good for cleaning the carpet boundary to the skirting board. Lastly that version has a little hole in the back for self cleaning (you take the head off and push the pipe into it and it flushes the pipe with solution).
There's a number of variants of the spot wash with similar naming - some corded, some with batteries, some with large motors and some with different attachments (like the pet attachment).

Supposedly the battery version charge gives 25 mins but the recharge time is slow and you can't swap out the battery. Hence I went corded and would again - I did two days of 5+ hours of cleaning. The great thing is the unit has a cable tidy and a pipe tidy built in.
Also I sort of settled on the VAX anti-bacterial solution, although there's a premium variant with carpet guard in it. I went through the 500ml and a 1.5L solution when doing the house! We now have 2 litres of solution ready for the next time. Fluffs up the carpet, removes the dirt/dust/grease from feet and has a nice smell too.
I also have some 'Cybergold Stain Remover" which a friend in the high price end of the carpet industry (2nd gen) recommends. If it's good for £100+/sqm then it's good enough for our poverty carpets! It also really really does work on the ingrained stains that the vax solution failed to move. Naturally you then use the vax over the top and clean up with it.
