My neighbor in Portland had the same thing happen with a kit from some startup, and we just ended up using a cheap pole mop with microfiber and a little vinegar, works perfect and never scratches.

Taking the lowball was smart, but the real win is that she liked you enough to send referrals. Most clients who pay full price just take your invoice and vanish. A referral from someone who got a steal makes you look like a hero to their friends, not a bargain bin. Plus, those five new clients might pay your normal rate, so you basically bought a marketing campaign for $850 off. I'd do that trade again every week.
