How every page rescues you
Department-store sites display everything and decide nothing — you get a wall of specs and homework. Every SmartBuyCompare page is built to hand you the decision instead:
- Key specs — the essence, not the encyclopedia. Store pages bury the five specs that decide it under fifty that don't. We pull the five out. Your evening back.
- Why this pick — chosen, not just listed. Out of thousands of look-alikes, we tell you which one we'd buy, and why, in three lines.
- The honest note — the catch, up front. Every product has one. Stores bury it in fine print. We print it in orange before you pay.
- Three stores, real prices, one page. The same product at Amazon, Walmart and Target, side by side — every price checked, and the check date printed on the page. When the lowest price is tied, we say so, and we say which store we send you to.
- +α — the value twin, trade-off included. Nearly the same performance for at least 20% less, when one honestly exists — and what you give up for the saving, stated in one line, never hidden.
- Why this comparison — a reason, not a dump. Every comparison tells you why these two belong together, and what the price gap buys you — or costs you.
+α — THE VALUE OPTION
Nearly the same power — $260 less.
Nearly the same performance as the compared pick — for much less money.
And the +α store can be any of the three — even when Amazon wins the comparison, the find may be at Walmart or Target.

Why does the cheaper one last longer between bag changes? The Gen 2 dock also washes mops, so it carries water tanks and a smaller dust bag (3.2L · 100 days). The D20 dock only collects dust — a bigger bag (4L · 120 days).
