ro unit - I'd recommend a merlin. £230
Tank - I'll assume you want an IBC - £35 not cleaned, £50 cleaned
Pole - if you are mostly domestic and only do ground and 1st floor then an 18f extender/predator would be a good choice - £75 extender, £115 predator
Brush - included in the price of the pole, we mostly stock the salmon monofilament brushes, although we can supply any brush you want.
