Saw this and thought it looks a good offer, so I ordered one for collection at my nearest Argos. Went to collect it yesterday, but rejected the first one offered as Nilfisk seal was broken, and the box had obviously been opened and resealed with sellotape. Box was plain white and approx 65cm wide, 30cm deep and 55cm high. Second one brought to the counter, but was exactly the same, opened and taped up.
Didn't fancy a repacked item for obvious reasons and asked for a refund, which to Argos credit was actioned immediately, had the Paypal refund notification email inside 10 minutes.
Tried another nearby Argos, but their item was the same, i.e. white box opened and taped up, so didn't get it.
Carried on with other shopping etc, and over a coffee thought maybe I was being too picky, and that if there was anything missing or broken Argos would sort it and perhaps this was the reason they had the offer running. So, on way home, called at first Argos and bought another one.
This one (Titan X-Tra) appeared in a full colour retail box, approx 25cm x 28cm x 75cm, with Nilfisk seal intact. Much happier with this.
PS There is a discrepancy with Nilfisk product numbers between the Argos website and the item collected, but Nilfisk have so many compact washer offerings, it doesn't really matter.
