Aiper’s Black Friday sale is giving folks some of the best opportunities to stock up on quality autonomous cleaning solutions for when summer rolls back around, with its advanced Scuba S1 Pro Cordless Robotic Pool Cleaner down at $835.99 shipped and matching at Amazon. This newer model is more recently spending time at $1,200 after it fell from its original $1,400 MSRP after launching in May, with most of the discounts we’ve seen keeping things between $950 and $1,000. The two Prime Day events this year saw the lowest drops though, with July lowering prices to $855, while October saw a further fall to $836 for the first time. That latter rate is returning here today for a second shot at the all-time lowest price we have tracked, giving you $364 in savings on the most advanced model under Aiper’s flag. What’s more, you’ll also be getting some free gifts in the form of a free hook and four free roller films along with your purchase, worth $60.
